Abstract

A trunnion and socket assembly is provided. The trunnion and socket assembly includes a trunnion, a socket, and a retention assembly. The trunnion includes a first portion and a second portion, the second portion defining an outer diameter. The retention assembly includes at least two cap elements and a ring member. The cap elements are coupled in an abutting relationship with a first surface of the socket. The cap elements have a second surface and a third surface. The ring member is adapted to be coupled in an abutting relationship with the third surface of each of the cap elements. The ring member has a fourth surface and a fifth surface. The ring member defines an inner diameter that is greater than the outer diameter of the second portion of the trunnion.

First claim

What is claimed is:

1 . A trunnion and socket assembly, comprising:
a trunnion having a first portion and a second portion, the second portion defining an outer diameter; a socket having a cavity formed therein, wherein the trunnion is adapted to be received into the cavity, the socket having a first surface defining a plurality of first apertures in a spaced apart arrangement from each other; and a retention assembly for retaining the trunnion in the socket, the retention assembly including:
at least two cap elements adapted to be coupled in an abutting relationship with the first surface of the socket, each of the at least two cap elements having a second surface and a third surface defining a plurality of second apertures therethrough in a spaced apart arrangement from each other; and
a ring member adapted to be coupled in an abutting relationship with the third surface of each of the at least two cap elements, the ring member having a fourth surface and a fifth surface defining a plurality of third apertures therethrough in a spaced apart arrangement from each other, wherein the ring member defines an inner diameter such that the inner diameter of the ring member is greater than the outer diameter of the second portion of the trunnion,
wherein the plurality of third apertures of ring member; the plurality of second apertures of each of the at least two cap elements, and the plurality of first apertures of the socket are adapted to be aligned with each other to receive mechanical fasteners therethrough.
