LUBRICATION RETAINING BEARING ABSTRACT This invention relates to lubrication retaining bearings. As is well known in the art, the interface between heavy load bearing surfaces of two relatively movable parts is subject to considerable wear, and when either of the parts has become too worn, it must be replaced at great expense. Moreover, when insuf- ficient lubricant is provided, the two parts occasionally lock together and interfere with the normal safe operation of the apparatus. The present invention provides a convenient and effective device for retaining a lubricant between relatively movable parts, which device Is relatively inexpensive to manufacture and easy to use. In accordance with the invention, there is pro- vided an improved lubrication retaining shim bearing arranged to be inserted between the two parts. The bearing includes an upper shim for engaging one of the parts, a lower shim for engaging the other part, and a middle shim having a plurality of apertures therethrough. A lubricant is retained between the upper and lower shims, and between the shims and their respective parts. In an alternative embodiment, the upper and lower shims are fixed with respect to the parts, and the lubricant is confined between the upper and lower shims.
