Method for resisting pivoting movement between an outer member and an inner member of a universal joint

摘要

A method for resisting pivoting movement between an outer member and an inner member of a universal joint includes engaging the outer member with the inner member in a chamber for pivoting movement through a first range of movement with a plurality of balls disposed in a plurality of inwardly facing grooves of the outer member and a plurality of outwardly facing grooves of the inner member to transmit rotation between the outer member and the inner member. The method includes enclosing the chamber portion with a boot having a plurality of convolutions defined by roots extending radially inward and resisting pivoting movement of the inner member relative to the outer member with an inner surface of a root contacting a shaft portion of the inner member upon the inner member and the outer member pivoting beyond the first range of movement.
