Abstract
A retainer (76) is disclosed for retaining a first element to a second element. Various construction details are developed which provide means to secure a second element to a first element wherein the elements are highly stressed, such as the rotating components of a turbomachine. In one particular embodiment, the retainer has a deformable portion (86) on one end, an internally threaded portion (88), and a shoulder (84) disposed on the end opposite the deformable portion and having a flat surface (92) to prevent rotation of the retainer during assembly. The deformable portion extends through cooperating retainer apertures (52, 68) in the two elements. The deformable portion is flared in place to produce a clinching force between the deformable portion and the shoulder and thereby secure the two elements together.
