摘要:
A bushing assembly for use in eliminating axial and radial play in a connection joint is disclosed wherein the bushing assembly is comprised of various members which can be interconnected so that it can be assembled as a unit. Although various embodiments of the invention are disclosed, the bushing assembly of the present invention generally comprises first and second concentrically mounted sleeve members which are engaged along oppositely tapered surfaces such that the sleeve members, when axially tightened, are radially expanded. Both of the sleeve members are axially split so as to create a hoop stress which aids in eliminating the axial and radial play and which can increase the fatigue life of the connection joint.
