Abstract: Constant velocity joints are used in vehicles to transmit a torque from the drive train to the driven wheels and at the same time to allow bending movements to allow the vehicle to drive around bends or to dip the chassis relative to the driven wheels. An outer ring of a tripod roller has flanges which retain rollers and retain an inner ring. During assembly, the inner ring is cooled such that its diameter is reduced such that it can be moved into position axially without interference from the flange. Once the parts return to the same temperature, the inner ring and rollers are retained.

Abstract: A tripod roller for a constant velocity universal joint includes inner and outer rings separated by a set of rollers. During assembly of the tripod roller the rollers are assembled to one of the inner and outer rings and then the other of the inner and outer rings is moved axially into position. Then, a forming tool is applied to one of the rings, in a direction perpendicular to the roller axis, to create a securing region. The securing region prevents relative axial movement of the two rings during the assembly of the universal joint.
