In a Hooke's joint, needle bearing cups 2 have their transverse end walls 11 spaced from the end walls 12 of the trunnions 1 by means of an elastomeric sealing ring 7 compressed between a shoulder 8 and radial flange 9 on the trunnion 1 and cup 2 respectively which limits the inward movement of the cup. The ring may have a circular, bi-, tri-, or quadri-lobar section, and may have one or more sealing lips. The cups 2 are retained in the yokes 6 by force fit and/or by forming over forging beads 13a.</p> |
