RIMOSTAT®-Torque Limiters RSHD for heavy-duty applications Features • 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 • Superb wear-behaviour during high energy consumption • High temperature resistant Built-in component (e. g. flange, pulley, chain wheel, etc.) (optional) Bearing bush Bx (optional) Friction pad wear indicator Friction pad Pressure ring Assembly group spring carrier 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 68-3 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. v-belt pulley) 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. • No wear adjustment required due to coil springs.
