Synchronisation control in tripod construction - has friction reducing elements between roller carriers and rollers, acting against relative rotary movements and applying relative axial forces

摘要

Friction-reducing elements are located between roller carriers (137) and rollers (140). These act against relative rotary movements between the two, and apply relative axial forces. A roller bearing (145,146) is located between one end face of a roller, and an opposite surface of a retainer element, fastened to the roller carrier. The roller of the roller bearing s held in a cage (147) and is either a ball or a conical needle. A holder (185) with a reduced sliding friction is located between a roller end face and a face of the roller carrier. ADVANTAGE - Excitation forces are reduced due to slide friction in joint.
