Abstract
A retainer for the installation of a seal or other component within a machine assembly including concentric first and second machine parts. One of the machine parts is formed as including a gland having a forward end wall and first and second peripheral walls. The first peripheral wall is spaced-apart a first distance from the other machine part and extends intermediate the forward end wall and an open rearward end, with the second peripheral wall being formed contiguously within the first peripheral wall intermediate the forward end wall and the open rearward end. The second peripheral wall is spaced-apart a greater second distance from the opposing machine part, and terminates at a rearward end wall. The retainer has an annular body configured to be receivable intermediate the first and second machine parts. The body extends from a forward end portion receivable within the gland to a rearward end portion configured as defining a plurality of cantilevered segments each extending from a proximal end to a distal end and having a camming surface. The segments are resiliently yieldable responsive to the bearing of the camming surface on the first peripheral wall of the gland to allow …
