Self-crimping connection for inner and outer members and method of assembling the same.

摘要

A self-crimping connection for inner and other members and a method of making the same includes providing the inner member (1) with stepped cylindrical exterior walls defining an outboard wall (12) of reduced diameter relative to an inboard wall (11), with an annular groove (17) being formed in the outboard wall; providing the outer member (4) with a stepped bore defining an internal outboard wall (21) and an inboard wall (22) to slidably receive the outboard and inboard walls respectively of the inner member, with an annular groove (25) being formed in the outboard wall of the outer member; and providing a first bushing (2) encircling the outboard wall of the inner member and a second bushing (3) extending circumferentially within the outboard wall of the outer member, with each of the first and second bushings having a body portion (30) and a crimp collar portion (31), in an arrangement such that as the inner member and the associated first bushing are axially pressed into the outer member and its associated second bushing, the crimp collar portion of the first bushing is crimped into locking engagement in the annular groove in the outboard wall of the outer member, and the crimp collar portion of the second bushing is crimped into locking engagement in the annular groove in the inner member, to thereby prevent relative axial movement of the inner and outer members. Preferably one of the walls is also knurled so as to also prevent relative rotation of the inner and outer members.
