Problems solved by technology

[0002] At present, the domestically produced J201 electric brush is composed of copper powder, graphite powder, and medium-temperature asphalt. After mixing and sieving, it is pressed into various green bodies of different specifications. After heat treatment, it forms a semi-finished product, which is machined into a finished brush. Due to the limitations of formula and process, this kind of brush has poor lubricity and conductivity. When it is used in high-power motors, especially imported motors, it will generate large sparks and rapid temperature rise. It cannot quickly form an oxide film, and the motor cannot be guaranteed. normal operation

Embodiment Construction

[0020] In order to illustrate the invention, the following examples are provided.

[0021] The brush material is compounded from the following components with 200 kg components:

[0022]

[0023] The tungsten disulfide can greatly reduce the friction coefficient of the material and increase the wear resistance of the material;

[0024] The active molecules of the oleic acid are used to activate the active molecules on the edge of the graphite molecular layer, so that it can form a chemical adsorption effect with the metal powder, improve the pressing effect, thereby improving the structural performance of the brush material, and its production The density uniformity of the billet is guaranteed, and the flexural strength of the brush material is improved. The colloidal powder acts as a binding agent;

[0025] The phenolic resin, epoxy resin and denatured alcohol are mixed and the mixed resin solution is used to impregnate the brush material. The purpose is to improve the s...

Abstract

The invention discloses a method for manufacturing an electric brush used for an industrial motor. In the method, a main material is formed by proportioning 52 kilograms of copper powder, 5 kilograms of tungsten disulfide, 2 kilograms of surfactant oleic acid, 41 kilograms of rubber powder, 15 kilograms of phenolic resin, 5 kilograms of epoxy resin and 80 kilograms of industrial alcohol. The invention also discloses a preparation process for the electric brush used for the industrial motor. The method has the advantages of high abrasion resistance, prolonged service lives of the electric brush and a motor slip ring and the like.

Description

technical field [0001] The invention relates to a manufacturing method of a brush for industrial motors, which is applied to industrial large AC and DC motors or imported motors. Background technique [0002] At present, the domestically produced J201 electric brush is composed of copper powder, graphite powder, and medium-temperature asphalt. After mixing and sieving, it is pressed into green bodies of various specifications. After heat treatment, it forms a semi-finished product, which is machined into a finished brush. Due to the limitations of formula and process, this kind of brush has poor lubricity and conductivity. When it is used in high-power motors, especially imported motors, it will generate large sparks and rapid temperature rise. It cannot quickly form an oxide film, and the motor cannot be guaranteed normal operation. [0003] The purpose of the present invention is to improve the physical properties of the brush, ensure the uniformity of the volume density ...
