ABSTRACT:
A multiple disc torque limiting clutch is presented. A stack of friction discs are splined to an output hub with a stack of separator discs interposed therebetween and keyed to a housing. Spring cup assemblies are positioned through openings in the separator discs to urge the separator discs into forceful contacting engagement with the friction discs. The spring cup assemblies include a compressed helical spring maintained within a cylindrical member and transmitting the spring force through the cylindrical member against the stack of separator and friction discs. The housing elements are of substantially unitary construction, with no relative movement capable therebetween. A wear indicator passes through the housing and indicates the degree of wear of the disc elements, while clearances between the interior of the clutch and the exterior are maintained at a minimum to provide a substantially explosion proof unit.
