Title (EN) LUBRICATION RETAINING BEARING
(FR) PALIER A RETENTION DE LUBRIFIANT
Abstract: front page image
(EN)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 insufficient 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 provided an improved lubrication retaining shim bearing (10) arranged to be inserted between the two parts (14, 32). The bearing (10) includes an upper shim (38) for engaging one of the parts (32), a lower shim (40) for engaging the other part (14), and a middle shim (42) having a plurality of apertures (44) 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 (38, 40) are fixed with respect to the parts (32, 14), and the lubricant is confined between the upper and lower shims (38, 40).
(FR)Paliers a retention de lubrifiant. Comme il est connu dans l"art anterieur, l"interface entre les surfaces d"un palier a charge elevee est sujette a une usure considerable, et lorsque l"une ou l"autre des pieces sont trop usees, elles doivent etre remplacees, entrainant une depense elevee. De plus, lorsque la lubrification est insuffisante, les deux pieces peuvent se coller ensemble et empecher le bon fonctionnement de l"appareil. La presente invention prevoit un dispositif convenable et efficace pour la retention d"un lubrifiant entre des pieces mobiles lequel dispositif est peu onereux et facile a utiliser. Selon l"invention, il est prevu un palier ameliore pour la retention d"un lubrifiant (10) dispose de maniere a etre insere entre les deux parties (14, 32). Le palier (10) comprend une cale superieure (38) cooperant avec l"une des pieces (32), une cale inferieure (40) cooperant avec l"autre piece (14), et une cale mediane (42) ayant une pluralite d"ouvertures traversantes (44). Un lubrifiant est retenu entre les cales superieures et inferieures, et entre les cales et leurs pieces respectives. Dans une variante de mise en oeuvre, les cales superieures et inferieures (38, 40) sont fixees par rapport aux pieces (32, 14) et le lubrifiant est renferme entre les cales superieures et inferieures (38, 40).
