Cylindrical roller bearing support for trunnions in fork eyes of universal joints

摘要

Support means for trunnions in fork eyes of universal joints comprising a bearing bushing consisting of a generally cylindrical sleeve section and a bottom section closing one axial end of the sleeve section adapted to axially support the trunnion and a plurality of cylindrical rollers arranged in at least two side by side rows. The rollers engage and roll between outer races in the bore of the sleeve section and inner races on the trunnion. The sleeve section has a constant uniform diameter over its entire outer peripheral surface and has outer races formed in its bore section which are offset in steps radially inward towards the bottom section. The inner races are disposed in side by side array on the trunnion and of the same diameter without offset.
