Sliding thrust bearing for a wet running rotary pump

摘要

The plain thrust bearing for a wet-running circulating pump has a first bearing ring(1) with wave forms(3,4) in the running surface(2) orientated towards the second bearing ring and formed by injection, pressing or thermal reworking of the bearing ring. The wave forms are designed so that in the region of the prominence(3) bearing surfaces and non-bearing surfaces are formed in between. The material of the bearing is built on a carbon base. The running surface is formed without material removal machining.
