Axial slide bearing turbocharger shaft in IC engine - has lubrication gap with profiled ring surface rotating with/around shaft, and wedge surfaces defined radially by sealing web

摘要

The bearing is for the shaft (14) of a turbocharger for an IC engine. It has a profiled ring surface (24), rotating with or around the shaft, several radial lubricant oil grooves (26), and wedge surfaces connected to these in circumferential direction. A locking surface is formed between each wedge surface and the neighbouring lubricant groove. Grooves and wedge surfaces are defined radially outwards by a sealing web. In the area of the lubricant grooves, the web has sediment grooves (30), which are open to the outside and to the lubricant grooves.
