Bearing material with low friction coefficient

Abstract

The invention discloses a bearing material with a low friction coefficient, and belongs to the technical field of mechanical materials, wherein the bearing material comprises the following raw materials by weight: 10-30% of ultra-high molecular weight polyethylene, 10-20% of carbon fibers, 10-20% of nitrile butadiene rubber, 1-2% of a plasticizer, 5-10% of a self-lubricating agent, 0.5-5% of zincoxide, 0.1-1% of stearic acid, 0.1-3% of a cross-linking agent, 0.2-3% of an antioxidant, 5-10% of a modified resin, 0.5-1% of di-sec-octyl phthalate, 1-2.5% of a foaming agent and 0.2-0.8% of a flameretardant. According to the invention, the components are novel, the advantages of self-lubrication and wear resistance of the ultra-high molecular weight polyethylene are maintained while the wear resistance is further improved by introducing the self-lubricating agent, the carbon fibers and other components, the heat resistance of the bearing is further improved by adding the flame retardant and the antioxidant so as to prolong the service life of the bearing, so that the high-requirement occasion of the bearing is further met.

Description

technical field [0001] The invention belongs to the technical field of mechanical materials and relates to a bearing material, in particular to a bearing material with a low coefficient of friction. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings. [0003] There are two main methods of marine bearings: water ...

Problems solved by technology

[0004] The present invention aims to solve the problems that the bearings made of traditional bearing materials have a relatively large friction coefficient, which is easy to cause temperature rise after high-speed operation, resulting in melting of lubricating grease, further reducing wear resistance, and affecting the service life of the bearing, etc., and provides a low friction coefficient The bearing material, by changing the components of the bearing material, the bearing can obtain higher wear resistance, which can meet the use of high-demand occasions
