Two piece clutch brake

摘要

A clutch brake is formed from a pair of identically shaped semi-annular halves. One end of each of the halves is formed with a first circumferentially extending protrusion located near the outer circumferential edge thereof. Each of the opposite ends of the halves is formed with a second circumferentially extending protrusion located near the inner circumferential edge thereof. The outer protrusions are disposed adjacent to the inner protrusions in circumferentially overlapping fashion. A pair of radially extending threaded fasteners are used to secure the two clutch brake halves together. The threaded fasteners extend radially through aligned apertures formed in the overlapping outer and inner protrusions. The radially innermost ends of the threaded fasteners extend a sufficient distance so as to engage splines formed on a transmission input shaft upon which the clutch brake is mounted. Notches are formed on the outer surfaces of each of the clutch brake halves to easily position a chisel or similar tool to fracture the two halves when it is desired to remove the clutch brake from the shaft. A plurality of apertures may be formed through and a plurality of recessed areas of reduced thickness may be formed in each of the semi-annular halves to reduce the weight of the clutch brake.
