RIMOSTAT® Torque Limiters RS RINGSPANN - 1

Advantages • Particularly suitable in applications with frequent slipping • Better stability of slipping torque than Belleville spring torque limiters over duration of the operating period • Adjustment of slipping torque setting according to the number of active springs – not through modification of spring pressure The RIMOSTAT® Principle The contact pressure on the friction surfaces is produced by long coil springs. Because of the RIMOSTAT® Torque Limiter’s linear, flat-angle characteristic of the pressure force, practically no reduction of the slipping torque occurs even when friction linings are subjected to wear. As the diagram 64-3 shows, compared with Belleville spring torque limiters, assuming a friction wear of Δf the reduction of the slipping torque ΔM is negligible. Function Slipping torque M • When the preset slipping torque has been reached the built-in component (e. g. chain wheel) slips. • During the slipping process, input and output rotate relative to each other and the preset slipping torque continues to be transmitted. • Inherent in the slipping process is a high energy consumption. • Re-engagement is not necessary.
