Abstract
The invention relates to a bimetallic bearing and belongs to the technical field of bearings. In the bimetallic bearing, a middle layer is arranged outside an inner layer of the bearing; a substrate outer layer is arranged outside the middle layer; the inner layer is made of a high-strength slide block material; the substrate outer layer and the middle layer are closely combined through a sintering process; the inner layer and the middle layer are closely combined through the sintering process; and the material of the middle layer is obtained by sintering spherical copper powder. The bimetallic bearing has the advantages of higher working strength and longer working life.
Description
Technical field
The present invention relates to a kind of bimetallic bearing, belong to technical field of bearings.
Background technique
Present employed bimetal sliding bearing is the sheet material of making at surface of steel plate sintered copper alloy layer that contains two kinds of metals and characteristic, and rolling becomes bimetal sliding bearing.But two layers of material is in use because in conjunction with the not firm damage of bearings that causes, and because the material behavior of sheet material itself adds the man-hour seam crossing and has the slit rolling, makes bearing deforming easily under the load greatly, influences the working life of bearing.So to improve in the course of the work the bearing bimetallic material in conjunction with fastness, simultaneously the butt joint place carries out the welding of degree of precision, to improve the working life and the working strength of bearing.
Summary of the invention
In view of the defective that prior art exists, the objective of the invention is to provide a kind of bimetallic bearing, and this bimetallic bearing has higher working strength and long operating life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bimetallic bearing, and the internal layer of described bearing is outside equipped with the mesosphere, and the mesosphere is outside equipped with the matrix skin, the employing high strength sliding block material of described internal layer; Described matrix is outer combines closely by sintering process with the mesosphere, combines closely by sintering process in internal layer and mesosphere, and the material in mesosphere is a spherical copper powder sintering gained.
Described high strength sliding block material mainly is made up of matrix and lubricated piece, and described matrix and lubricated piece are combined closely by sintering process, and fixes by the locating stud that is positioned at four jiaos of lubricated pieces; The composite material that the material of lubricated piece adopts Pb-free copper-alloy ball powder and solid lubricant co-sintered to be obtained; Matrix adopting high strength alloy material; The working surface of described lubricated piece is inlaid with the several solid oiling agent.
The invention has the beneficial effects as follows: a kind of bimetallic bearing, the internal layer of described bearing is outside equipped with the mesosphere, and the mesosphere is outside equipped with the matrix skin, the employing high strength sliding block material of described internal layer; Described matrix is outer combines closely by sintering process with the mesosphere, combines closely by sintering process in internal layer and mesosphere, and the material in mesosphere is a spherical copper powder sintering gained.This bimetallic bearing has higher working strength and long operating life.
