Clamp Style Shaft Collars for Food Equipment

Marlborough, MA - Ruland manufactures clamp style shaft collars with high holding power, fine finishes, and precise face to bore perpendicularity. They are commonly used for guiding, spacing, stopping, mounting, and component alignment on food processing, packaging, and handling equipment.

Food equipment manufacturers benefit from the tightly controlled face to bore perpendicularity of Ruland shaft collars (TIR of = .002" or .05mm) which is critical when they are used as a load bearing face or for aligning components such as bearings or gears. All Ruland shaft collars are machined to a fine burr free finish that reduces places for bacteria to be trapped and complements or enhances the appearance of food processing equipment. They are manufactured from solid bar stock that is sourced exclusively from North American mills.


Clamp style shaft collars do not mar the shaft, have high holding power, and allow for simple positioning adjustments. They distribute compressive forces evenly around the shaft for a tight fit and improved holding power when compared to set screw collars. Two-piece styles offer in-place installation and disassembly, increased holding power, and are mated throughout the manufacturing to ensure proper fit and alignment. The Ruland name and bore size are stamped on every shaft collar for ease of identification.

Ruland shaft collars are supplied with fastening hardware that tests beyond industry standards for maximum torque capabilities and holding power. Shaft collars made from 303 and 316 stainless steel utilize hardware of like material for consistent corrosion resistance and to meet regulatory standards. All stainless steel hardware undergoes an in-house surface treatment process to prevent galling. Delrin or plastic shaft collars can be used as a cost effective alternative to stainless steel at the expense of performance. They are supplied with stainless steel hardware for corrosion resistance.


Patented hygienic clamping assemblies eliminate traditional shaft collar hot spots such as screw pockets,
saw cuts, and surface imperfections where bacteria can buildup and transfer into the system. They are designed for corrosive high pressure washdown environments and provide a smooth uninterrupted surface for easy cleaning, making them a more hygienic alternative to standard shaft collars.

ContiTech Ensures Higher Productivity and Falling Operating Costs

Improved design, expanded range of lengths, higher availability: the wrapped narrow-section V-belt Conti-V Advance from the ContiTech Power Transmission Group is now available, not just for project business but also as a stock item in small quantities. Thanks to a tensile member made of reinforced polyester, a fiber-reinforced compound, and a doubled fabric jacket, the belt is ideally suited to high-performance applications.

  • Wrapped narrow-section V-belts ideal for high-performance applications
  • Increase of well over 40% in power potential compared to standard V-belts
  • Now available as stock items


ContiTech developed the Conti-V Advance particularly for heavy-duty drives in the general mechanical engineering sector. The narrow-section V-belt is typically used in compressors, fans, construction machinery, and gardening equipment. It is also suitable as a coupling belt as well as for applications that require counterflexing. "The Conti-V Advance offers increased overall efficiency as well as an increase of well over 40% in power potential compared to standard V-belts," explains Regina Arning, head of the Industry segment at ContiTech Power Transmission Group. "The better longitudinal stability also ensures minimal maintenance outlay. This allows the operating costs to be reduced and productivity increased."

Another advantage – since the Conti-V Advance transmits significantly more power than a conventional V-belt, drives in which belt sets are used can be designed to be much narrower. The number of belts can thus be reduced, which helps to save on system costs. In accordance with ISO 1813, the Conti-V Advance is electrically conductive, temperature resistant from -30°C to +80°C, has limited oil resistance, and is available in SPZ, SPA, SPB, and SPC profiles.



Heavy Duty Shaft Collar

Heavy duty shaft collars from Ruland have a larger outer diameter, width, and forged screws for increased clamping force and axial holding power. This makes them an ideal fit for bulk material handling, shaking, inspection, loading, and filtration systems in industries such as oil and gas, sand and gravel, paper, water treatment, and off-highway equipment.
Standard bore sizes range from 3" to 6" and 75mm to 150mm and are available in 1215 lead-free steel for high holding power and 303 stainless steel for added corrosion resistance. Ruland shaft collars are manufactured using select North American bar stock and hardware that exceeds DIN 912 12.9 standards.
Ruland offers heavy duty shaft collars in one- and two-piece clamp styles. One-piece shaft collars have high holding power, allow for simple positioning adjustments and do not mar the shaft. Two-piece shaft collars have a higher holding power and can be installed without removing other components from the shaft. Two-piece styles are mated together throughout the manufacturing process for proper fit and alignment.
Ruland large bore shaft collars are machined to ensure a consistent face to bore perpendicularity of TIR < 0.076mm. The face to bore relationship is important for many applications where components such as bearings need to be properly aligned on the shaft. It also creates even pressure on the interfaced components prolonging their life and reduces the likelihood that the shaft collar will shift when it is subject to shock loads. A circular groove on the shaft collar indicates that it has been single point faced. Ruland collars should be installed so that the circular groove is on the side that will receive the shock load or against the components that need precise positioning or even pressure.


Raw-edge V-belt from ContiTech: more power, longer service life

Growth for the drive belt range: With the FO Pioneer, the ContiTech Power Transmission Group introduces a high performance raw-edge V-belt for drive solutions in machine and plant engineering. Compared to the FO Advance, the FO Pioneer offers up to 20 percent more power transmission and longer service life – a development that demonstrates the extensive material expertise of the specialist in rubber and plastics technology.

The raw-edge drive belt is oriented towards the needs of the industry. It owes its improved product properties to its base material ethylene propylene diene monomer rubber. “EPDM has numerous advantages over conventional rubber compounds,” explains Regina Arning, Head of the industry segment at the ContiTech Power Transmission Group. “The material is dynamically more stable and has a higher temperature resistance ranging from -40 °C to + 120 °C.”


A sub-construction made of EPDM forms the basis, a tensile member made of polyester and a cotton cover provide more stability. The new belt is resistant to dust and tropical conditions, it is also conductive according to ISO 1813 as well as partially oil resistant. It will be available in the fourth quarter of 2015 and will replace the FO Advance in dimensions up to 2,932 mm. “Our customers benefit from a consistent development, whereas the price level remains the same,” says Arning. For applications that require belt lengths over 2,932 mm, ContiTech continues to offer the V-belt FO Advance.



Five-meter mark exceeded - ContiTech timing belts in hovercrafts


In two new hovercrafts, the British manufacturer Griffon Hoverwork relies on timing belts with carbon tensile member of the ContiTech Power Transmission Group.

With 5,502 mm and 4,956 mm, they are the longest endless polyurethane belts that were ever produced. They drive the propellers and turbines of the giant hovercrafts, which are employed to connect Portsmouth (England) and the Isle of Wight. The belts are made in cooperation of ContiTech and Griffon Hoverwork at the ContiTech site in Dannenberg.

The two new hovercrafts, which are currently under construction, each have two propellers and fans that interact in order to set the vessels in motion. The propellers and fans are driven by timing belts. “Due to the high powers that are transmitted within the drives of the hovercrafts, the Synchrochain Carbon is the ideal belt for this application,” explains Barrie Oldham, Industrial Sales Director ContiTech UK. The vessels are equipped with two engines with 793 kW (1,079 hp). The high amount of power is needed: The hovercrafts take roughly the area of a tennis court and carry up to 88 people.

Griffon Hoverwork has equipped the drives of their hovercrafts with timing belts for quite some time. However, the cooperation with ContiTech, the use of the Synchrochain Carbon as well as endless timing belts, which exceed the five-meter mark, are new. “ContiTech is the only manufacturer who can craft timing belts in the required lengths,” says Oldham.

The Synchrochain Carbon is very wear-resistant and abrasion-proof, it transmits high powers extremely reliable. This makes it the ideal solution for the hovercrafts of Griffon Hoverwork. The heart of the belt is the carbon tensile member, which at the same load stretches less than an aramid tensile member. In addition, the high stiffness of the cord minimizes pre-tension losses and the efficiency of the drive is further enhanced. The belt is thus virtually maintenance-free – which helps to minimize costs in the area of maintenance and replacement.

The two new hovercrafts of Griffon Hoverwork will connect the city of Portsmouth and the Isle of Wight and will start operation in the course of 2016. This ferry service is already run with two hovercrafts of Griffon Hoverwork.

Timken Researchers Address Critical Issue for Wind Turbine Operators

Research conducted by The Timken Company (NYSE: TKR; www.timken.com), a global maker of bearings, to address a critical issue for wind turbine operators received the 2015 Wilbur Deutsch Memorial Award from the Society of Tribologists and Lubrication Engineers (STLE). Timken researchers used their deep technological expertise to solve customer problems in the wind energy sector and underscored the value of Timken® Wear-Resistant® bearings in helping to prevent smearing damage to turbine gearbox bearings.
Dr. Maureen Hunter, president of the Society of Tribologists and Lubrication Engineers, presents the 2015 STLE Wilbur Deutsch award to Dr. Ryan Evans of The Timken Company. Dr. Evans and three other Timken associates co-authored a research paper on the root cause of smearing in wind turbine gearbox bearings.

Dr. Ryan Evans, manager of engineering fundamentals and physical testing at Timken, led a team of researchers in investigating the root cause of smearing damage to turbine gearbox bearings manufactured by various companies. It was known that lightly loaded high speed shaft bearings (usually cylindrical roller bearings, or CRBs) in turbine gearboxes sometimes exhibited smearing damage in bands across various surface areas. These smeared areas can be initiation points for much more severe damage over the service life of a bearing.

The specific bearing assembly dynamics that caused the smearing were not well understood, and other researchers had been unable to reproduce the damage on full-size CRBs in a laboratory. "It took us a few months and some creative test-rig settings and instrumentation to determine how to generate the smearing damage. In addition, we recognized the importance and value of measuring key bearing dynamic attributes like cage slip in real time," Dr. Evans said. "We took it a step further and were able to model the test conditions using the Timken CAGEDYN dynamic model, which led to a proposed 'smearing criterion' that can be used to assess smearing risk in other bearings and dynamic situations."

The team's research proved that erratic load zone conditions contribute to smearing damage. "As that was the only way we could reproduce the damage in a laboratory, others outside Timken increasingly point to the same mechanism as an explanation for not only smearing, but other types of bearing damage in real wind turbines," Dr. Evans said.

He and three other Timken researchers co-authored the award-winning paper that presented the results. They are Todd Barr, principal product development engineer, based in North Canton, Ohio; Steve Boyd, senior application specialist – product, also based in North Canton; and Luc Houpert, senior scientist – product, based in Colmar, France.



Ruland disc couplings for semiconductor and solar equipment

Marlborough, MA - Semiconductor and solar equipment such as wafer handlers, bonders and screen printers often require rapid movements over short increments to precisely position wafers, chips or panels. Disc couplings from Ruland are torsionally stiff, operate with zero-backlash and have a balanced design, making them an excellent choice for these highly accurate systems with speeds of up to 10,000 rpm.

Disc couplings are comprised of two anodized aluminum hubs for low inertia and multiple flat stainless steel disc springs that allow for a substantial amount of shaft misalignment while remaining rigid under torsional loads. Ruland carefully fastens the discs to the hubs to ensure a secure fit that does not allow for any backlash or play. The disc springs are very thin, allowing them to bend easily under all types of misalignment with relatively low bearing loads.



Ruland disc couplings have a balanced design for reduced vibration, benefiting solar and semiconductor equipment which often position items that are highly sensitive to minor vibrations. The balanced design also allows for higher speed capabilities of up to 10,000 rpm. Single disc styles are well suited for applications where compact installation is required. Double disc styles have a center spacer to increase misalignment capabilities. The center spacer is available in anodized aluminum for general purpose use, or insulating acetal for electrical isolation. Parallel misalignment is accommodated by the double disc style or by essentially using two single disc couplings in tandem.

Ruland manufactures disc couplings with or without keyways in inch, metric and inch to metric bore combinations ranging from 1/8” to 1 1/4” (3 mm to 32 mm). All hardware is metric and tests beyond industry standards for maximum torque capabilities. Stainless steel hubs and spacers and custom designs are available by special request.

Disc couplings are part of Ruland’s complete coupling line which includes rigid couplings with precision honed bores and five styles of motion control couplings: beam, bellows, disc, zero-backlash jaw and oldham. All Ruland products are manufactured in its Marlborough, Massachusetts factory and are RoHS2 and REACH compliant.

Established in 1937, Ruland focuses on the design and manufacture of high performing shaft collars and couplings. All products are carefully manufactured in Marlborough, Massachusetts USA factory under strict controls using proprietary processes. 3D CAD files, full product specifications, and additional technical information, are available at www.ruland.com.

Ruland Oldham Couplings for Printing Applications


Marlborough, MA - Ruland manufactures zero-backlash oldham couplings that accommodate high amounts of parallel misalignment with low bearing loads and have a balanced design for reduced vibration at higher speeds. Print equipment manufacturers benefit from the combination of flexibility and accuracy of motion. The three-piece design allows for in place servicing without machine disassembly, a useful feature for removing or changing out rollers.

Ruland oldham couplings consist of two hubs that mate to a torque transmitting center disk making them adaptable to a wide variety of printing applications. This three-piece design is ideal for equipment where the roller must be frequently changed out. Hubs can be left in place and the roller can be quickly removed by sliding the disk and assembly off the driving hub. Oldham couplings are highly customizable and can easily combine clamp and set screw hubs with inch, metric, keyed, and un-keyed bores. Hubs are standard in black anodized aluminum for improved lubricity, increased life, and low inertia. Ruland utilizes a proprietary hub machining process that leaves a smoother surface for interaction between the hub and disk leading to a longer life and increased performance.



Oldham couplings transmit torque by mating the slots on the center disk to the drive tenons on the hubs. They accommodate angular and axial misalignment, and are especially useful in applications where parallel misalignment is present. The replaceable center disk is available in acetal plastic for high torsional stiffness, nylon for shock absorption and noise reduction, and PEEK for high temperature and low out-gassing. In the event of wear or failure, the disk can be easily replaced restoring the coupling’s original performance characteristics. Oldham couplings have the advantage of electrical isolation due to the non-conductive nature of the center disk preventing electrical currents from being passed to delicate instruments which can cause inaccurate data readings or damage.

Ruland offers oldham couplings with bore sizes ranging from 1/8” (3mm) to 1-1/8” (30mm). Stainless steels hubs are available upon request for use in high corrosion or clean room environments. Disks can be manufactured with a center hole to allow further shaft penetration or tapped holes to attach the disk to a hub so it stays in place during disassembly.

Oldham couplings are part of Ruland’s complete coupling line which includes rigid couplings with precision honed bores and five styles of motion control couplings: beam, bellows, disc, zero-backlash jaw, and oldham. All Ruland products are manufactured in its Marlborough, Massachusetts factory and are RoHS2 and REACH compliant.

Twice the Rated Fatigue Life for Longer Life in a Variety of Environments
New BNEQARTET Long Life Bearing for Front-Loading Washers


NSK Ltd. (NSK; Headquarters: Tokyo, Japan; today announced that it has developed BNEQARTET, a new long life bearing for front-loading washers. This new product achieves more than twice the rolling fatigue life of that of the standard product used for drum support in front-loading washers, delivering longer life in a variety of usage conditions. NSK is targeting 1.5 billion yen in annual global sales for this new product in 2018.

Development Background
In the European market, the size of the drums used in mainstream front-loading washers is increasing in order to accommodate larger laundry capacity. As a result, the load placed upon drum support bearings is increasing, which can result in shorter bearing life.

Due to the fact that washers have space constraints and must be energy-saving, there is an inevitable increase of load on the bearing which cannot be countered by simply making the bearing larger. In response to this, NSK leveraged one of its core material technologies to increase the life of the bearing while keeping it the same size as the standard product.

Product Features
NSK developed the material for this new bearing through a combination of alloy component optimization and proprietary cleaning control technology, enabling double the usage life under heavy load conditions. The new bearing is also reliable under harsh conditions, including those that involve exposure to contamination.

Twice the rated fatigue life
Suppression of surface-originated flaking due to stress concentration from dents caused by contamination
Suppression of white structure flaking
Suppression of flaking in high-temperature environments

Accumulation chains from iwis


wis accumulation chains ensure not only easy positioning of the conveyed material with simple mounting points, but also prevent jerky chain stops and starts.


iwis accumulation chains have idler rollers on both sides that serve two purposes: firstly, they engage with the sprocket teeth to transmit power, and secondly, they support the chain in the profile.

One special feature are the
slightly protruding bushes in the inner link (1) which prevent contact corrosion between inner link and outer plate.



Low-friction rollers
All 1/2” and 3/4” iwis accumulation chains are fitted with low-friction sintered metal rollers (
2) that provide consistent and extreme light running and are not slowed down by lubricant.

The length of our application conveyor can therefore be built about
30% longer without any need for modification of the drive motors; alternatively, if the system length remains unchanged, smaller drive units may be fitted. Less strain on the chain and drive means a longer service life for the entire conveyor system.

ContiTech and Techmi built Europe’s longest conveyor


November 2014 - The conveyor belt is installed across a distance of 6.2 km at a French cement factory.

Faster, longer, more innovative: When it comes to peak performances, ContiTech knows a thing or two – and now has another achievement to add to its portfolio together with its partner Techmi. The longest conveyor belt in Europe recently went into operation at a cement factory in Montalieu, France.

The community of Montalieu lies in eastern France between Lyon and Geneva. It’s a small town located on the banks of the Rhône and home to the cement plant Vicat. To bring in limestone from the quarry 6.2 km away, Vicat required a cost-effective solution and launched a project to realise its transport needs by conveyor belt. They engaged Techmi, the French expert in bulk handling to build up the entire conveyor system. Techmi compiled in 2012 a quotation including specific requirements concerning the belt. In 2013, ContiTech beat a large number of other bidders to the contract and so became Techmi’s strategic partner.

“Requirements for this conveyor belt are tough, especially for return solution,” reports Stefan Hoheisel, Segment Leader for Industry at the Conveyor Belt Group. The result of the project is something to be proud of: The endless belt is about 13 km long and does a twist and turn on the head and tail of the system to run parallel to the loaded belt on the return. “For Vicat and Techmi the classic return solution wasn’t really an option on this occasion. The innovative turn solution means we now have a base construction which is not higher than just 80 cm,” explains Nicolas Raphaël, team leader of the French conveyor belt team. Another advantage is that limestone residues remain on the returning belt rather than falling underneath it. This makes the system considerably easier to clean and is an advantage not just for Vicat but also for the environment.


The system blends into its surroundings without any difficulty – based on a patent of Techmi. Concrete walls and a cover encase the conveyor belt. People, animals and vehicles can cross over the construction without any problems.

The 250 tons conveyor belt is now in operation, powered by three electric motors delivering 250 kW each. In normal conditions, the belt can transport up to 700 tons of limestone an hour. At maximum capacity, it can shift as much as 1,000 tons. The belt has officially been in operation since mid October.



Exclusive parking solution at a dizzy height

For the parking lift of a luxury loft, timing belts are used as load-carriers

The Hamilton Scotts Apartments are one of the best residential addresses the city-state of Singapore has to offer. Residents of the 30-storey condominium can park their luxury cars directly in front of their apartment. This is enabled by a fully automated parking lift sytem of Wöhr, which employs ContiTech timing belts.

Residents of the Hamilton Scotts Apartments do not park in front of the building or in a garage, but take their vehicles to the floor they live. Through a large glass pane, they can marvel at their vehicles in the “Sky Garage” from their sofa, while at the same time, they can let their eyes wander over the Asian metropolis.

While the residents reach their apartments by a passenger elevator, the parking lift takes their cars over at an access point at the ground floor in order to carry and park them in front of the particular apartment. This solution is not only exclusive, it also offers excellent space efficiency: “While underground parking requires extensive ramps and driving lanes, the parking lift system uses the existing space in the manner of a high bay,” says Andreas Zangerle, Development Manager of Wöhr.

Extra long belts
The belts that lift the vehicles up to a height of 370 feet come from ContiTech. “For very high parking lifts, timing belts are our first choice,” says Zangerle. For the first time, they were used in 2006 for the parking systems in two 170 feet high towers in Mumbai, India.

For the project in Singapore, Wöhr has ordered 6,600 feet of the timing belt CONTI® SYNCHRODRIVE, in single lengths around 400 feet. “It is actually a standard belt”, says Thomas Winkler from the Application Engineering of ContiTech Power Transmission Group. “But it has never been installed in such lengths before”. Usually, the belt is used in industrial lifting applications, where differences between 30 to 100 feet must be bridged.

Large weights are not a problem for the CONTI® SYNCHRODRIVE – it features steel cord, the strongest tension member in the ContiTech belt portfolio. But the belt provides other important characteristics as well, which are important for the project: A noise-reducing cover fabric makes it anti-static. “This protects the control electronics of the parking lift and can prevent disturbances in its operation,” says Winkler. In addition, the tension member has been optimized: it offers a very low elongation and an improved setting behaviour, which is important for the length required in Singapore.

Smooth parking
The cars are lifted on parking pallets. “The quick-change pallet system allows very speedy access, so that parking and exiting functions takes place smoothly and fast,” explains Zangerle. The car elevator lifts up to ten tons upward with a speed of 9 feet per second. The elevator platform measures approximately 20 by 20 feet, it is supported by two timing belts at each corner.

“Of course, a rope or chain drive would have been a cheaper solution for the parking lift,” says Winkler. But that applies only to the purchase. Due to the much lower maintenance costs of the belt – for example, lubrication is unnecessary – and their longer lifespan, belts are the more effective solution by far. Also, the noise level is kept within narrow limits, so that residents are not disturbed. And the teeth of the belt prevent slippage, so that the parking lift comes to stop where it is supposed to, without complex position control.

Speeds, loads and available space are just some of the many factors that must be taken into account when designing a drive system capable of reliably meeting the demands placed on it, during long term operation." explains Daniel Thalmann, Application Engineering Manager at NKE.

One of the major strengths of the Steyr-based rolling bearing manufacturer is its range of single row cylindrical roller bearings. NKE manufactures over 3,000 different variants, which enable an enormous variety of application possibilities. The bearings are suitable for high radial loads and moderate to high speeds. Made from pure rolling bearing steel, they have an exceptional lifespan, while the raceways' high surface quality reduces the operating temperature down and wear. The inner and outer rings of the cylindrical roller bearings can be fitted separately, simplifying installation. Notable for their outstanding economy and operating reliability, they can be produced at the Steyr factory with short lead times.

In addition to cylindrical roller bearings, NKE's standard portfolio of industrial gearbox bearings comprises spherical and taper roller bearings as well as angular contact and deep groove ball bearings. Of particular interest are the company's special bearings for gearboxes, which are developed in close cooperation with the customer and ensure optimum balance of space and performance.

NKE offers gearbox manufacturers a comprehensive service including consulting, assistance with design, calculations and training courses. All bearings made by NKE are subject to stringent quality requirements and are tested using modern inspection and measurement procedures.

NKE produces standard and special bearings for all industrial applications. Engineering, product development, production and final processing of components, modular assembly, quality assurance, logistics, sales and marketing are centralised at NKE's headquarters in Steyr. A wide range of standard bearings is available from stock or at short production lead-times. NKE also provides tailored products and solutions. NKE's products are distributed through 15 international representative offices and more than 240 distribution outlets in 60 countries.



CONTI® POLYROPE replaces steel ropes in elevators


Alternative suspension means offers advantages in comparison to steel ropeslifespan reduces maintenance costsin 25 mm and 50 mm wide versionsback side allows narrower construction width

With the CONTI® POLYROPE, ContiTech further develops the successful flat belt technology, which was introduced in the elevator industry in the late 1990s. The CONTI® POLYROPE is certified according to the Lift Directive 95/16/EC, available in two different widths, with and without profiled back side and offers numerous advantages compared to conventional steel ropes.

Over 100 years, steel ropes were indispensable as suspension means for elevators. Around the turn of the millennium, first alternatives came up with robust polyurethane belts, which were much lighter than steel ropes, allowing more efficient drives and easier maintenance. Now, ContiTech pursues this development: “The composite rope CONTI® POLYROPE is a patented solution of ContiTech,” says Hubert Göser, head of research and development at the ContiTech site in Dannenberg, Germany. “It is available on the free market for elevator manufacturers all over the world.”


CONTI® POLYROPE
The composite rope CONTI® POLYROPE consists of steel cables that are embedded in a coat made of polyurethane. As suspension means for lifts, it offers numerous advantages in comparison to steel ropes.



Advantages in comparison to steel ropes
The CONTI® POLYROPE features 2 mm thick steel ropes consisting of 49 individual strands, which are embedded in a polyurethane coating. They give the suspension means its high tensile and breaking strength. The coating is durable, resistant to hydrolysis and has very good traction properties: even at maximum load, a reliable power transmission is given. The CONTI® POLYROPE is available in 25 mm and 50 mm wide versions and with a flat as well as with a profiled back side.

As a result, the product offers an extremely long life span. The CONTI® POLYROPE holds up to three times longer than comparable steel ropes and is 20 % lighter, it also does not need to be lubricated. This helps to reduce downtime and maintenance costs.

CONTI® POLYROPE
The back side of the new variants of the CONTI® POLYROPE feature a profile. In a 2:1 elevator suspension, deflection pulleys can be provided with a corresponding profile, which enables a smaller and narrower construction width.



More space in the shaft
While the inner side of the CONTI® POLYROPE is fluted and lead exactly on accordingly profiled drive pulleys, the prototype has a flat back side. Since the flat side of the CONTI® POLYROPE runs over deflection pulleys in a 2:1 suspension, these are slightly curved outwards, so that the suspension means can centre up. Due to the convex shape, drive and guide pulleys need to be wider than with steel cables.

For this reason, ContiTech has developed more variants of the CONTI® POLYROPE, with back sides featuring a profile. “Deflection pulleys can be provided with a corresponding profile, which enables a smaller and narrower construction width. Thus they take even less space in the elevator shaft,” says Göser. “The obtained space can be used for other components.”


Certified by renowned testing institute
The approval of the CONTI® POLYROPE as suspension means for elevators was granted by the Dutch testing agency Liftinstituut after successful examination. “The Liftinstituut is internationally renowned in the elevator industry,” says Göser. “Thus, a certification by the Liftinstituut opens doors for marketing in the whole world.” The CONTI® POLYROPE is not yet fitted as standard – but the developments of elevator manufacturers are in full swing.


Beam Couplings for Medical Applications

Ruland beam couplings are zero backlash, have high torsional stiffness and accommodate misalignment making them well suited for encoder, tachometer, and light duty power transmission applications commonly found in medical equipment. They offer low inertia, light bearing loads, and a balanced design for reduced vibration at higher speeds.

Ruland beam couplings utilize two sets of overlapping spiral cuts to increase torque capabilities and torsional rigidity when compared to the commodity style single beam coupling. Separating the spiral cuts into two sets gives the coupling better parallel misalignment capabilities while easily accommodating angular, complex, and axial misalignment. Zero backlash beam couplings are ideally suited for test and measurement, robotics, imaging, patient positioning, liquid chromatography, and lab analysis equipment which require accuracy of motion.

Ruland beam couplings are available with four or six beams in inch, metric, and inch to metric bore combinations ranging from 3/32" (2mm) to 3/4" (20mm). Four beam couplings are more flexible with lower bearing loads while six beam couplings feature a larger body size with shorter spiral cuts to provide increased torque capability, repeatability, and torsional stiffness. Multiple beam couplings are available in aluminum for additional flexibility and low inertia or stainless steel for higher torque and increased corrosion resistance. Special dimensions, spiral cut patterns, finishes, and materials are available by request.

Beam couplings are part of Ruland’s complete zero backlash coupling line which includes: rigid, beam, bellows, disc, jaw, and oldham types. All Ruland couplings are manufactured in our Marlborough, Massachusetts factory and are RoHS2 and REACH compliant.

Established in 1937, Ruland focuses on the design and manufacture of high performing shaft collars and couplings. All products are carefully manufactured in Marlborough, Massachusetts under strict controls using proprietary processes. 3D CAD files, full product specifications, and additional technical information, are available at www.ruland.com.

A ContiTech innovation is among the strongest timing belts in the world

Extreme performance and impressive dimensions make the ContiTech Power Transmission Group’s CONTI® SYNCHROCHAIN CARBON a top player among timing belts. At almost five metres long and 22 centimetres wide, it transmits 315 Kilowatts of power onto the drivetrain of a high-performance shredder by a company called UNTHA.

When it comes to heavy-duty polyurethane timing belts, the CONTI® SYNCHROCHAIN CARBON is in the top league. With tension members from carbon, it can transmit extreme traction forces, with outstanding performance and durability guaranteed. But an enquiry from Kuchl, in the Austrian state of Salzburg, presented the ContiTech Power Transmission Group with a new challenge: A company called UNTHA, which produces industrial shredders, was looking for a drive belt for its highperformance flagship model, the TR3200. The belt would have to transmit 315 kilowatts to the enormous machine’s drive train to enable it to process up to 15 tonnes of domestic waste per hour.

Teaming up for development

At five metres in length and 22 centimetres across, the belt they were looking for “was way beyond anything we had in our portfolio at the time,” recalls Axel Thor, Sales Manager with ContiTech Austria in the town of Wiener Neudorf. Responsible with trading partner Synchrotech Antriebstechnik GmbH for taking care of customers in the Alpine republic, Thor passed the request from Kuchl on to the team at the Power Transmission Group in Dannenberg.



Highest specifications


A conversation with Christian Lanner provides clarity over why UNTHA chose ContiTech to supply the heavy-duty belt it needed. Describing the incredibly tough requirements on industrial shredders like the TR3200, the company’s Head of Product Management says: “Most of our machines work in the open air or unheated halls across various continents around the world. In Guatemala temperatures can reach 45 degrees Celsius or more, while in Scandinavia our machines have to work at 20 degrees below zero.” But irrespective of climate differences, shredders have to be sure to deliver the tremendous forces needed to tear materials of any kind into pieces no larger than 30 millimetres – small enough to fall through the perforated screen in the machine. In preparing household refuse for heat recovery, materials are first pre-shredded and sorted. The next stage of processing falls to secondary shredders like the TR3200. “After that, granulates can be used as fuel,” Lanner explains. As a source of power, granulates from waste are particularly beneficial to more energyintensive industries, such as cement production, as they save oil, gas, coal and other fossil fuels, and consequently help protect the environment. Treated waste of this kind also benefits waste management companies, as EU landfill guidelines coming into force in many European countries allow domestic refuse to be deposited in landfills only in exceptional cases, or indeed not at all. Before the new high-performance belt could finally go into operation, it had to undergo rigorous testing.
Fine-tuning for top results

To protect the belt during prolonged use, the engineers at UNTHA decided to modify the drivetrain of their shredder. “While we were testing, we decided to replace the shear pin couplings we’ve used until now with a shift segment coupling,” Christian Lanner explains. “The new coupling is far more precise, so if the machine is operated incorrectly or overloaded, it prevents the belt from being damaged.”

When it came to putting the finishing touches to their product, the specialists in Dannenberg remained ambitious. “During this final stage our people managed to make the tension members even stronger and integrated additional carbon fibres into them,” says sales expert Axel Thor. Along with Synchrotech’s Manuel Spanner, he was in constant contact with both the customer and production at ContiTech throughout. After months of testing and fine-tuning, the world’s strongest PU timing belt finally reached series maturity.

Good prospects

Collaborative development work for this product has been a worthwhile undertaking for all sides. Our ContiTech belts are currently driving 35 machines around the world – and numbers are rising all the time. “At the moment our most important markets are the UK and Poland,” announces UNTHA’s product manager Christian Lanner with delight. He is also looking ahead to a bright future, as the product is expected to sell especially well in eastern and southern European countries, where the implementation of EU landfill guidelines is firmly on the agenda.


Axel Thor is among those who are highly satisfied with international collaborations on this project. He is full of praise for cooperations with the customer. “For ContiTech this is a success story, without doubt,” he says. Not least because “UNTHA has already indicated that they intend to fit more machines with our belts – wood shredders, for example.”

Number of engines with belt drives growing faster than those with chain technology • Timing belts in oil can be narrower than the dry-running version • System competence for the entire drive

Less friction + less weight = less fuel consumption – and so fewer CO2 emissions. This simple formula is a dominant theme today in the development departments of automotive manufacturers and their suppliers. It has long ceased being all about grand savings and has instead become a matter of highly detailed work, since every saved gram of CO2 counts in the final analysis.This is one of the reasons why the timing belt in the timing assembly has gained significantly in importance once again in recent years. Volkswagen is again fitting belts instead of chains in the Golf VII and Audi A1. And other manufacturers too are increasingly designing their new engines for high-tech drive belts made from rubber and plastic, because they know that belts have distinct advantages over chains in reducing fuel consumption and CO2 emissions from combustion engines.The latest development at ContiTech Power Transmission Group is the timing belt in oil: It can be made narrower than the model which runs in the dry and is even quieter as the oil not only reduces friction but also damps the belt.

Image Download (JPG, RGB, 300dpi, app. 13x22cm, 1.5MB)

Studies also confirm this: According to FEV GmbH, an independent engine designer, the belt drive lowers fuel consumption compared to the chain, and therefore reduces CO2 emissions. In a 1.6 liter gasoline engine, for example, the belt drive reduces fuel consumption by more than 1% and saves up to 1.5 grams of CO2 per kilometer. "Belt drives are lighter and run a lot more quietly too. Belts don't tend to lengthen either," says Hermann Schulte, head of Timing Belt Development at the ContiTech Power Transmission Group. "A significant advantage, because a lengthening chain alters the engine timing. As a result, consumption increases and performance drops. Emissions levels are quickly exceeded." In endurance tests, a belt lengthened by just 0.1% after 240,000 kilometers of service life – the figure was five times greater with a chain.Many large automotive manufacturers in Europe are now making use of the benefits of timing belts in their engines and this number is growing. ContiTech supplies dry-running timing belts to manufacturers including Audi, Volkswagen, Volvo, Ford, Opel, and PSA. It's not only camshafts that are controlled by timing belts, but injection systems and oil pumps too. ContiTech developers are already considering whether to use a timing belt to drive balance shafts as well and therefore make spur gears superfluous. And their focus is on unconventional yet safe solutions, such as the timing-belt-in-oil system. "Since the start of 2013, the ContiTech Power Transmission Group has been part of the group of series production suppliers for these applications. Timing belts are already in use for oil pump and timing drives in the newer Ford, PSA, and Volkswagen engines," says Ralf Berger, head of Key Account Management and Application Engineering at the ContiTech Power Transmission Group.What was previously unthinkable is today running along without a hitch in series production. To achieve this, ContiTech has adapted the elastomer, the fabric, and the cord to the new environment. In addition to polyamide and aramid fabric with a Duralon coating containing Teflon, an ultra-durable rubber compound made from ACN-HNBR (hydrogenated acrylonitrile butadiene rubber), as well as E-glass and K-glass, is also being used for high length stability. Because of these special components, even impurities in the oil cannot harm the belt, whereas simple soot particles in the oil can destroy chains.The advantage of the timing belt in oil is that it has a narrower construction than the dry-running version and it is even quieter. In the case of a crankshaft pulley with 19 teeth, no noise can be detected, even with the engine operating under full load, because the oil not only reduces friction, it absorbs sound as well. This is important for the simple reason that the increasingly popular downsized engines generally run less smoothly. Here is where a belt can help minimize vibration and make driving a pleasant experience despite the use of environmentally friendly technology.Benchmark trials also demonstrate that belts today have at least the same and often even better properties than chain drives with their hydraulic tensioners and plastic guides. This is why developers are no longer concentrating on durability – this has long been a given. In on-road tests, the belts still ran without a hitch even after 300,000 kilometers.The question today is one of making the belts even narrower – every millimeter counts, because installation space in vehicles is becoming ever tighter. "This is where the belt has another advantage. The engine designer has more flexibility in designing the belt drive than with a chain," says developer Hermann Schulte. The aim is to reduce belts for the camshaft drive in the next generation of engines from today's 16 – 20 mm width to 14, 12 or even 10 mm. Belts for oil pump drives currently measure just 9 mm – and so are as narrow as a chain.Yet when it comes to the issue of reducing weight, it is not enough to consider the belt alone. Tensioners, idlers, and toothed pulleys are critical too. This is why developers at the joint venture company ContiTech-INA are already working on drives that can make do with simpler, and therefore lighter, tensioning systems. Or even none at all. In this way more grams can be saved and the CO2 emissions ultimately reduced even further. Vehicle manufacturers are backing this trend with their development commissions and in so doing reveal their confidence in ContiTech's many years of experience in the field of drives.
The many advantages offered by modern timing belts, including their long service life, reduced friction and reduced noise, will again expand the market share of timing belts. Experts estimate that it will include at least two thirds of European vehicles in 2015 and over 70% in 2017. The share of belts running in oil will more than double from today's 8% to over 20%. A development that will benefit the environment and motorist alike.
