Abstract

A self crimping connection for inner and outer members and the method of making the same includes providing the inner member with stepped cylindrical exterior walls defining an outboard wall of reduced diameter relative to an inboard wall with an annular groove in the outboard wall; providing the outer member with a stepped bore defining an internal outboard wall and an inboard wall to slidably receive the outboard and inboard walls, respectively, of the inner member, with an annular groove in the outboard wall of the outer member; a first bushing encircling the outboard wall of the inner member and a second bushing encircling the outboard wall of the outer member, with each of the first and second bushings having a body portion and a crimp collar portion, the arrangement being such that as the inner member and first bushing are axially pressed into the outer member and its associate second bushing, the crimp collar portion of the first bushing is crimped into locking engagement into 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 into the annular groove in the inner member. Preferably, one of the walls is also knurled so as to also prevent rotation of these members as well as axial movement relative to each other.
