R+W Coupling Technology - Calculating Application Torques

As a provider of flexible drive couplings and ball detent safety clutches, we are often asked to provide a bit of assistance in calculating application torques, especially for customers looking to retrofit existing equipment. (read more)

R+W Coupling Technology - Reliability under the most extreme conditions

Thousands of tons of copper matte is removed daily from the world's largest copper mine, which is 4,300 meters long, 3,000 meters wide and 850 meters deep . Huge bucket wheel excavators are used for this operation. To avoid very costly excavator downtimes, mechanical safety couplings by R+W are used to limit the force in the main and auxiliary drives (read more)

R+W Coupling Technology - 24 hours a day, 365 days a year

Depending on the application, extreme temperature ranges, heavy soiling, a high degree of vibration, and continuous operation 24 hours a day, 365 days a year are the prevailing conditions for tunneling technology. The mining material is transferred to conveyor belts and transported several kilometers for processing. (read more)

R+W Coupling Technology - Design Considerations for Heavy Equipment

The world of high horsepower drives often calls for mechanical design to be approached from different perspectives. As motors, gearboxes and machines increase in size, power density can become disproportionate from one driveline component to the next, emphasizing the need for more rugged, robust and compact equipment to be used.
