Embodiment Construction
[0011] A bimetallic composite material bearing comprises a matrix outer layer 1, an intermediate layer 2, an inner layer 3 and an inorganic lubricating film 4. The inner layer 1 of the bearing is provided with a middle layer 2, and the middle layer 2 is provided with a matrix outer layer 1; the matrix outer layer 1 and the middle layer 2 are closely combined through a sintering process, and the inner layer 3 and the middle layer 2 are closely combined through a sintering process; The material of the inner layer 3 is a composite material obtained by co-sintering lead-free copper alloy ball powder and solid lubricant; the material of the middle layer 2 is obtained by sintering spherical copper powder; a layer of inorganic lubricating film is sprayed on the working surface of the inner layer 3 4.
[0012] The material used for the base outer layer 1 is low-carbon cold-rolled steel plate or stainless steel plate.
[0013] The material used for the solid lubricating film 4 is grap...

The invention relates to the technical field of bearings, in particular to a bimetal composite bearing. The bimetal composite bearing comprises a substrate outer layer, an intermediate layer, an inner layer and an inorganic lubricating film, wherein the intermediate layer is arranged outside the inner layer of the bearing; the substrate outer layer is arranged outside the intermediate layer; the substrate outer layer and the intermediate layer are tightly bonded together by a sintering process; the inner layer and the intermediate layer are tightly bonded together by the sintering process; the inner layer is made of a composite material obtained by jointly sintering lead-free copper alloy ball powder and a solid lubricant; the intermediate layer is made of a material obtained by sintering spherical copper powder; and a layer of the inorganic lubricating film is sprayed on the working surface of the inner layer. The bimetal composite bearing has higher working strength and longer service life.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a bimetal composite material bearing. Background technique [0002] The currently used bimetallic sliding bearing is a plate made of sintered copper alloy layer on the surface of the steel plate, which contains two kinds of metals and properties, and rolled into a bimetallic sliding bearing. However, the bearing is damaged due to the weak combination of the two layers of materials during use, and due to the material characteristics of the plate itself, there are gaps at the joints during rolling processing, which makes the bearing easily deformed under a large load, which affects the bearing. service life. Therefore, in the working process, it is necessary to improve the bonding firmness of the bimetallic material of the bearing, and at the same time, perform high-precision welding on the joints to improve the service life and working strength of the bearing.
