Problems solved by technology

Among them, the integral casting of copper alloy means that all the bearings are made of copper alloy material, which leads to a large amount of copper alloy, a large machining allowance, and high manufacturing costs.
Centrifugal casting is a technology that injects liquid copper alloy into a high-speed rotating mold, and makes the molten metal centrifugally move to cast a layer of copper alloy on the substrate. Meet the wear resistance and corrosion resistance performance requirements of sliding bearings

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0028] like figure 1 As shown, the manufacturing method of the wind power sliding bearing of this embodiment includes the following steps:

[0029] 1) Make the bearing base 1, place the bearing base 1 horizontally, and rotate the bearing base 1 around the central axis of the bearing base 1;

[0030] 2) Simultaneously spray tin bronze powder 2 and laser beam 3 on the surface of bearing base 1, and intersect tin bronze powder 2 and laser beam 3 before spraying onto the surface of bearing base 1 to form cladding in the cladding area 4 of bearing base 1 layer 5;

[0031] 3) Moving the cladding area 4 along the axial direction of the bearing base 1 , and repeating step 2), until the cladding layer 5 is formed on the entire surface of the bearing base 1 .

Abstract

The invention provides a manufacturing method of a wind power sliding bearing. The manufacturing method comprises the following steps of: manufacturing a bearing base body, horizontally placing the manufactured bearing base body, and rotating the bearing base body around a central shaft of the bearing base body; simultaneously spraying tin bronze powder and a laser beam on the surface of the bearing base body, and enabling the tin bronze powder and the laser beam to be intersected before the tin bronze powder and the laser beam are sprayed to the surface of the bearing base body, so as to form a cladding layer in a cladding area of the bearing base body; and moving the cladding area along the axial direction of the bearing base body, and repeating the step 2) until the cladding layer is formed on the surface of the whole bearing base body. The manufacturing method has the advantages that the performance of the bearing is guaranteed, the cost is saved, the operation is convenient, and the like.

Description

technical field [0001] The invention relates to the field of sliding bearing preparation, in particular to a method for manufacturing a wind power sliding bearing. Background technique [0002] At present, sliding bearings usually use copper alloy integral casting or centrifugal casting. Among them, the integral casting of copper alloy means that all the bearings are made of copper alloy material, which leads to a large amount of copper alloy consumption, a large machining allowance, and high manufacturing costs. Centrifugal casting is a technology that injects liquid copper alloy into a high-speed rotating mold, and makes the molten metal centrifugally move to cast a layer of copper alloy on the substrate. It meets the performance requirements of sliding bearings for wear resistance and corrosion resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a metho...
