Environmentally-friendly plastic thrust bearing bush and production method thereof

Abstract

The invention relates to an environmentally-friendly plastic thrust bearing bush and a production method thereof. The environmentally-friendly plastic thrust bearing bush comprises a steel bush base and a surface plastic layer, wherein the surface plastic layer is bonded on the steel bush base directly by a solvent-free adhesive to form the thrust bearing bush, a spring cushion does not need to be arranged between the steel bush base and the surface plastic layer, and brazed connection is also not required between the steel bush base and the surface plastic layer. Compared with the prior art, the environmentally-friendly plastic thrust bearing bush and the production method provided by the invention have the advantages of short molding cycle, outstanding environmental performance, uniform elastic modulus and the like.

Description

technical field

[0001] The invention relates to a thrust bearing bush and a manufacturing method thereof, in particular to an environment-friendly plastic thrust bearing bush and a manufacturing method thereof. Background technique

[0002] Traditional elastic metal-plastic thrust bearings are mainly composed of three parts: steel base, elastic layer and polytetrafluoroethylene plastic layer. At present, there are mainly two preparation methods. One is to evenly spread plastic powder in the gap of the elastic layer composed of springs. Among them, it is molded under a certain pressure, and after high temperature sintering, it is brazed with the steel tile base with a tin-lead alloy; After the layers are combined, solder dipping is required, and then the composite layer and the steel tile base are brazed, and the solder is usually a tin-lead alloy liquid. Therefore, heavy metal lead is used in these two processing methods, and under high temperature conditions, tin-lead allo...
