Elastomer couplings with higher torque handling capacity
The growing popularity of curved jaw (elastomer) style couplings for precision applications has driven the need for couplings that handle more than the traditional torque capacity of 2,150 Nm up to a maximum torque of 25,000 Nm. Available with split clamping collars or keyway and set screw connections, the three new body sizes allow for […]
Six factors to remember about couplings in a motion system
Updated May 2019 || Physical values such as torque, torsional rigidity, spring stiffness, moment of inertia, imbalance, and zero-backlash play a major role in coupling design. Here are a few facts to keep in mind when you design your motion system. 1. Torque (Nm) is the product of an acting force and the effective length […]
For safety, electronics may not be the best choice
The trend of replacing mechanical systems with electrical systems continues. Even developers of hydraulic and pneumatic systems are following it. But, as is becoming evident through the latest unintended acceleration issues, electronic components can have a few drawbacks that should not be overlooked in a design. When in comes to designing a system for safety, […]
Thermoplastic Insert Couplings from R+W America
R+W has developed the ECOLIGHT- TX1 series of molded thermoplastic insert couplings. The couplings feature a dramatically reduced mass and moment of inertia, accompanied by a high level of chemical compatibility and tolerance for heat, making the TX couplings ideal for both pump drive and servo applications. These plastics also provide major cost reduction compared […]
Expanded Line of Servo Insert Couplings
The SERVOMAX line of precision elastomer insert couplings from R+W has been expanded to include both smaller and larger sizes as well as enhanced mounting options. The R+W SERVOMAX utilizes secondary heat treatment of the injection molded polyurethane insert to smooth out inconsistencies in the driving surfaces, allowing for a smooth fit and higher repeatability.
