Axial thrust clutch/bearing/freewheel

Abstract

A unidirectional clutch of the hyperboloidal type is provided having an inner race member defining an inner race surface, an outer race member defining an outer race surface and a plurality of thrust transmitting cylindrical rollers therebetween. Each of the rollers makes line contact with the inner race surface and line contact with the outer race surface along generators of these surfaces. A biasing member is provided for biasing the inner and outer race surfaces axially toward one another to maintain the rollers in line contact with both inner and outer race surfaces. The inner race member is connected to a driven member and the outer race member is connected to a driving member. Torque is transmitted between the driven and driving members causing the biasing member to impose a net axial force on the inner race member tending to urge the inner and outer race surfaces toward one another axially.
