Disc couplings from R+L Hydraulics with ATEX certification

R+L Hydraulics now offers Lovejoy disc couplings with ATEX certification. The specialist for power transmission technology and hydraulic accessories is owned by American coupling manufacturer Lovejoy Inc. and distributes the couplings throughout Europe. Typical applications for the ATEX-certified disc couplings are pumps and compressors for use in hazardous areas, such as the petrochemical industry. The disc couplings are suitable for rough environmental conditions. They are wear-free and excel with their high torsional rigidity and zero backlash. Lovejoy disc couplings furthermore require no maintenance and can be inspected without being dismantled. For use in hazardous areas, devices and components are classified according to device category, temperature class, explosion group and ambient temperature. The disc couplings’ certification covers the following categories: Ex II 2 GD c 135°C (T4) and Ex I M2 c for couplings with torques up to 259 kNm and Ex II 2 GD c 100°C (T5) as well as Ex I M2 c for torque values up to 4.6 kNm. There are ten versions of ATEX-certified disc couplings, covering a torque range from 0.24 kNm to 259 kNm. In addition to basic versions, various more sophisticated types with intermediate shafts or spacers are available. They are typically used in pumps and compressors. Specifically for use in the petrochemical industry, a series with spacer and guard ring – that fulfils the requirements of standard API 610 – is available. R+L Hydraulics produces a wide range of fluid and power transmission couplings as well as hydraulics accessories. Its products are used mainly in machinery, vehicles, hydraulics and in the steel and offshore industries.    www.jbj.co.uk...

The matching coupling for every shaft

Development and design competency for custom-made shaft couplings Shaft couplings are used in very different applications. Due to this, different coupling types with varying characteristics are required – as it is important that the coupling optimally matches the respective application. mayr® power transmission not only provides pioneering solutions for the increasingly popular high-performance couplings with high speeds, but also provides the decisive prerequisites for intelligent, networked machines with the ROBA®-DSM torque measurement shaft coupling. In machines and systems, shaft couplings transfer energy from one shaft to another in the form of torque and speed, and in the process compensate for any occurring shaft misalignment. In the course of this, each drive has its own special characteristics and places extremely different requirements on the couplings. As a result, depending on the application, the main focus is either placed on high torsional rigidity, large misalignment capability, low mass inertia, excellent damping capacity or even a combination of these characteristics. mayr® power transmission has developed and manufactured backlash-free shaft couplings for over 30 years and provides an extremely wide and sophisticated product range for different drive constellations featuring various steel bellows, elastomer and disk pack couplings. Precise thanks to ingenious design The smartflex® steel bellows coupling from mayr® power transmission is designed with a multiple-layer steel bellows which gives the coupling extremely high torsional rigidity. This ensures very high positioning accuracy and shaft run-out accuracy in servo axes even under difficult conditions, and guarantees an absolutely backlash-free and therefore flawless torque transmission between the two shafts. Furthermore, the multi-layer bellows design provides a much higher misalignment capacity in comparison to single-layer bellows....

Oldham couplings for printing applications

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. Roller can be quickly removed 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 customisable 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. Disk can be easily replaced 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...

UK FLOWTECHNIK HAS A DEDICATED IN-HOUSE PRODUCT TEAM IN THE UK

UK Flowtechnik Ltd is the UK stockist of HBE Hydraulic Components. HBE are German manufacturers of high quality, competitively priced drive couplings and hydraulic components such as oil tanks, heaters, coolers, level gauges and breathers. HBE develops and produces a large range of diverse hydraulic and drive components for power transmission and fluid technology applications. UK Flowtechnik also supply a range of magnetic drive couplings. The Softex is a low maintenance, fail-safe coupling The industry standard HBE Softex spider coupling is a popular choice when connecting motor/gear-box shafts for the purpose of power transmission. It uses the curved jaw design, which allows for greater shaft misalignments, and has a range of spider insert options for transmitting more or less torque, whilst offering varying degrees of shock absorption and noise reduction. The Softex is a low maintenance, fail-safe coupling and approved for ATEX Zone 1 hazardous area applications. The backlash-free Softex-ES design is an ideal coupling for high speed servo motor drives, torque transducers, encoders and all applications requiring high degrees of torsional stiffness connecting the drive shaft to the required system. It offers a cost effective alternative to bellows and steel lamina couplings. Available with both set-screw and clamp hub type fixing methods, there is also the new clamping ring hub design which is the perfect choice for high speed spindle drives of machine tools and heavy load presses.
