ABSTRACT:
The object of the invention is to provide a simple and cost-effective solution for reducing the wear and consequently for increasing the life of axial sliding bearings. For this purpose, the profiled annular surface (24, 24') of the lubricating gap (25, 25') arranged between the fixed bearing body (20) and the rotating bearing collar (19) is designed to rotate about or with the shaft (14). Said annular surface has a plurality of radially arranged lubricating oil grooves (26, 26') and, in each case, a wedge surface (27, 27') connected to these in the circumferential direction. A catch surface (28, 28') is designed between each wedge surface (27, 27') and the lubricating oil groove (26, 26') adjacent to the latter. The lubricating oil grooves (26, 26') and the wedge surfaces (27, 27') are delimited radially outward by a sealing web (29, 29'). The sealing web (29, 29') has, in the region of the lubricating oil grooves (26, 26'), dirt grooves (30, 30') which are open to these and which are likewise designed to be open in the direction of the bearing housing (17). Larger dirt particles contained in the coarsely purified lubricating oil (3) are consequently centrifuged out before they reach the lubricating gap (25, 25').
