Abstract

The invention discloses a self-lubricating bearing based on fiber fabric modification and a manufacturing method thereof. The self-lubricating bearing includes an outer bushing and an inner lining layer installed in the outer bushing. The inner lining layer includes a metal substrate and a For the fiber resin composite layer on the substrate, the fiber fabric treated with the silane coupling agent is first impregnated with the epoxy resin-based composite material to obtain the fiber fabric composite material, and then the fiber fabric composite material and the metal substrate are pre-pressed and thermally cured and thermally cured Two steps are used to obtain the flat dry friction self-lubricating composite material, and the flat dry friction self-lubricating composite material is rolled into an inner liner of a shaft sleeve and installed in an outer bush to obtain a self-lubricating bearing. The dry friction self-lubricating bearing of the present invention has better bearing capacity, its friction coefficient is effectively reduced, and its self-lubricating performance is significantly improved.

Description

Technical field [0001] The present invention belongs to the mechanical field, and relates to a method of manufacturing a sliding bearing, and particularly relates to self-lubricating bearings modified method for manufacturing a fiber-based fabric. Background technique [0002] Working conditions due to some constraints, and the slide bearing has to work (such as high temperature, high pressure, ambient dust) in the harsh working conditions, and the common fluid lubrication Bearing friction characteristics due to the limited material, not well adapted to this particular condition requirements. The self-lubricating bearings are better able to solve by relying on the limitations of grease lubrication in order to achieve better performance in maintaining oil-free conditions, so the self-lubricating bearing material research study is the mainstream trend, how to design a better self-lubricating bearings mechanical strength but also has good tribological properties is becoming a hot re...
