Patent JP-S4947737-A (JP)
IPC: F16C27/08
Filed: 1973-05-08
Abstract: A clutch release mechanism having an axial bearing wherein one of the race members is interconnected with a retaining bolt or securing pin movably extending through a central hole or bore of the housing of the release mechanism. A spring is arranged between the housing and the race member which normally biases the housing and bearing assembly apart but which allows them to be moved inwardly relative to each other when wear occurs to the clutch. Preferably, the spring is a coil spring surrounding the retaining bolt and the spring travel is limited on inward depression by a sleeve bushing coaxial with the spring and the retaining bolt. The free traverse of housing and bearing assembly defines the degree of play of the clutch on its closing and opening actuation.
