The LP Survivor Series of disc-pack couplings from R+W America, Bensenville, Ill. (www.rw-america.com), transmit torque using friction. A series of bushings press the disc pack together. Precise ...

I'm trying to calculate the friction torque between to flat surfaces rotating against one another, and can't find any examples of this particular problem for guidance--only for rotating cylinders.

You can't escape friction. The force that resists motion between two objects that are in contact with one another exhibits itself all over the place: in between your engine's rod bearings and its ...

This file type includes high-resolution graphics and schematics when applicable. Simply put, holding brakes hold rotating equipment in place: If rotation is not desired, a brake can be applied. Many ...
