Two-Year Project Produces Safety Coupling 60-70% Lighter
The German couplings specialist R+W has developed a safety clutch which, it claims, is 60–70% lighter than conventional designs, and allows smaller clutches to be used in some applications. The SL series clutch, which made its debut at the recent Motek exhibition on Germany, is the result of a two-year collaborative project with universities. The […]
Hybrid Coupling Combines Fluid, Electronics, Tubing and Cable
The Hybrid Connector integrates fluidics and electronics into a single connection point. Combining dual flow paths into an integral hose assembly eliminates the need for multiple connections and simplifies the user interface between modular tools, umbilicals or hand pieces and a device. Integrating high-cycle electrical contacts directly into the connector eliminates the need for a […]
6 ways to assess torque needs for safety couplings
Safety couplings that operate on the ball detent principle primarily suit disengagement torque applications. But, with some modification, they can suit highly dynamic applications with resonant frequencies and torsional rigidity. Here is a brief examination of common equations used to calculate the following torques for safety coupling design in a drive system: disengagement torque, acceleration […]
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, […]
Handbook for Mechanical Torque Limiters
As a part of a series of technical handbooks developed for the European manufacturing industry, R+W has released a new handbook for the design and application of safety and overload couplings. Covering the very basics of what torque limiters are, the varieties available, and why they are used, all the way though complex theories and […]
