The bearings for the journals of a universal joint a cross-brace

摘要

A bearing system in a universal joint for journaling each of the bearing pins at a cross trunnion includes a journal for receiving each one of the trunnion pins. At least two of the journals are mounted on a drive shaft flange and have projections which engage grooves in an end face of the flange for preventing radial and lateral displacement of the journals with respect to the flange. Each journal has a seating bore for receiving a pin of the cross trunnion. A bearing bushing, having a bottom wall and side walls, is carried in each seating bore. A roller bearing is positioned between the inside of the side walls of the bushing and the trunnion pin carried therein, and a removable guard ring is carried in an annular groove of each journal engaging the bottom wall of its respective bushing for securing the bushing in the seating bore, thereby permitting removal and replacement of the bushing and allowing the use of guard rings having different thicknesses to adjust for clearances.
