Abstract
A pin retention mechanism for a pivot joint which connects together two structural members of a machine for pivotal movement relative to each other. The pivot pin has a dynamic connection with one of the structural members and there is an annular spacer on the pivot pin adjacent the dynamic connection. The other structural member has a tapered opening through it with the taper either on the structural member itself or on a bushing within an opening in the other structural member. A collet in the tapered opening has an external surface mating with the tapered internal surface. A cylindrical sleeve is located between the collet and the pivot pin and in contact with the spacer.
