ABSTRACT:
A "standpipe" lubrication device for a universal joint assembly. In a preferred form, the lubrication device includes a plurality of annular protuberances on opposed first and second ends. The protuberances, serving as sealing and tolerance absorption media, define adjoining frustoconical and cylindrical surfaces. Each cylindrical surface terminates in a radially extending annular surface, the latter adapted to provide a self-locking feature against dislodgement of the device from a lubrication passage of the trunnion. Also in the same preferred form, the lubrication device is formed of a moldable material characterized by dimensional heat stability, for assuring proper operation at elevated temperatures.
