Problems solved by technology

At present, the main problem encountered by bearings is that the lubricity is poor, and the frequency of external lubrication is high. If there is a lack of oil or less oil, the wear resistance of the bearing will decrease significantly, and the service life will be reduced.

Abstract

The invention discloses a material and method for preparing a bearing. The bearing is prepared from, by weight, 55-65 parts of iron, 8-15 parts of zinc, 0.5-1.5 parts of cerium, 5-10 parts of manganese, 10-20 parts of copper, 8-12 parts of tin, 6-15 parts of graphite and 1-5 parts of nickel. The material and method for preparing the bearing have the characteristics of requiring no external oil supply and prolonging the service life of the bearing.

Description

technical field [0001] The invention relates to a bearing material, in particular to a material used for preparing the bearing. technical background [0002] Bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. When other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during the power transmission process and keep the center of the shaft fixed. pieces. It is a pivotal component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. At present, the main problem encountered by bearings is that their lubricity is poor, and the frequency of external lubrication is high. If there is a lack of oil or less oil, the wear resistance of the bearings will decrease significantly and the service life will be reduced. Con...
