Lubricating oil monitoring and maintenance cap and methods of installation

摘要

A roller for a tracked vehicle has a lubricating oil reservoir and an open end to the lubricating oil reservoir. The open end of the roller is closed by a cap removably coupled to the open end. The cap is a sealing body having an outer side facing away from the open end, an opposed inner side facing toward the open end, and a standoff structure formed in the inner side. A compressible gasket is applied between the inner side of the cap and the open end and is under a compression between the inner side of the cap and the open end of the roller forming a fluid-impervious seal between the cap and the open end of the roller. The standoff structure of the cap interacts between the cap and the open end holding the cap away from the open end limiting the compression of the gasket.

主权项

1. Apparatus, comprising:
an open end to a reservoir; the open end being closed by a cap coupled to the open end, the cap having an outer side facing away from the open end, an opposed inner side facing toward the open end, and a standoff structure formed in the inner side; a compressible gasket applied between the inner side of the cap and the open end and being under a compression between the inner side of the cap and the open end forming a fluid-impervious seal between the cap and the open end; the standoff structure of the cap interacting between the cap and the open end holding the cap away from the open end limiting the compression of the gasket between the cap and the open end; the standoff structure comprises standoff prominences each being in direct contact with the open end; and the gasket has a length and the standoff prominences are equal in size and are equally spaced-apart along the length of the gasket forming an equally spaced-apart standoff distribution along the length of the gasket.
