Patent

CA 2154538

The disclosure involves a new "pancake-like" thrust bearing arrangement with gravity-fed lubrication. The bearing is angular to a horizontal plane and has a top edge above such plane. A load-support structure oscillates on the bearing. Such bearing has a lubricant feed aperture at the top edge and plural lubrication grooves formed in the flat bearing face and connected to such aperture by feed passages. The grooves are oriented so that they "run downhill," i.e., so that they intersect a circle concentric with the bearing center. Grease moves by gravity along the grooves which are "closed- ended" to help prevent premature expulsion of grease from the bearing face.

Nouveau palier de butée de type plat, à lubrification par gravité. Ce palier est angulaire à un plan horizontal et possède un bord supérieur au-dessus de ce plan. Une structure porteuse de charge oscille sur le palier. Un tel palier présente une ouverture d'alimentation de lubrifiant dans le bord supérieur, et comprend plusieurs rainures de lubrification formées dans la face plate d'appui et reliées à l'ouverture par des passages d'alimentation. Les rainures sont orientées vers le bas, de façon à entrecroiser un cercle concentrique par rapport au centre du palier. La graisse descend par gravité le long des rainures qui sont fermées à l'extrémité pour éviter une expulsion prématurée de la graisse depuis la face d'appui.
