Embodiment 1

[0056] In the motors of the steel rolling production line, the commonly used motor carbon brushes are currently used. Taking the motor carbon brushes produced by ABB Co., Ltd. (Asia Brown Boveri Co., Ltd.) as an example, the general service life is only about 72 hours. The braids will come out and the motor carbon brushes must be replaced. After analysis, it was found that the main reason for the brush braids coming out was that the motor vibrated too much or the heating temperature was high, which caused the brush braids to be pulled, and the hard sealing glue between the brush braids and the carbon brush body was damaged. Due to the heavy load of the motor on the production line, vibration and heat are unavoidable, and it is difficult to solve the problem that the braids of the carbon brushes of the motor are easy to fall out and be damaged. ABB Co., Ltd. has not found a method for improvement either.

[0057] In order to prevent the brush braids from coming out, the applic...

Embodiment 2

[0096] On the basis of Embodiment 1, when the depth of the anti-loosening hole 110 is set in place in step 1, continue to cut the inner wall of the anti-loosening hole 110, so that the internal space of the anti-loosening hole 110 expands radially, forming a small opening and a large inside. The anti-loosening hole 110, the colloidal layer 500 formed after the colloidal material is shaped and hardened is not easy to come out from the anti-loosening hole 110, and the connection strength between the colloidal layer 500 and the carbon brush body 100 is improved.

[0097] Moreover, near the hard sealant 300 , the coverage of the glue layer 500 increases, which can further block heat transfer to the hard sealant 300 and improve the heat insulation effect.

[0098] like Figure 4 , Figure 4 A structure of the anti-loosening hole 110 is shown in , the middle part of the anti-loosening hole 110 expands in diameter to form a bottle shape with a small opening and a large middle part. ...

Abstract

The invention relates to the technical field of motor carbon brushes, in particular to a motor carbon brush reinforcing method and a motor carbon brush, and the motor carbon brush reinforcing method comprises the steps: 1, forming a heat insulation groove in the top of the carbon brush, forming an anti-loosening hole downwards from the bottom of the heat insulation groove with a brush braid as thecenter, and enabling the depth of the anti-loosening hole to be smaller than the sealing depth of a glue opening of the carbon brush; 2, removing dust and oil stains in the anti-loosening hole and the heat insulation groove; 3, filling the anti-loosening holes and the heat insulation groove with heat insulation anti-seismic colloid materials and shaping the colloid materials; and 4, placing the motor carbon brush in the storage space, and waiting for the colloid material to harden. According to the motor carbon brush reinforcing method provided by the invention, on the premise of not changingthe overall structure of the motor carbon brush, the service cycle of the motor carbon brush is prolonged, rapid batch processing can be realized, the method can be used for producing a new motor carbon brush and reinforcing the existing motor carbon brush, and the use cost of the motor carbon brush is saved.

Description

technical field [0001] The present application relates to the technical field of motor carbon brushes, in particular, to a method for strengthening motor carbon brushes and the motor carbon brushes. Background technique [0002] Carbon brush is a kind of sliding contact widely used in rotating electrical equipment. It is a device that transmits electric energy or signals between the fixed part and the rotating part of a motor, generator or other rotating machinery. When in use, the spring presses the carbon brush tightly. on the rotating rotating part. During use, the end face of the brush will gradually wear out, resulting in increased vibration and heat generation of the motor, or the situation that the motor load is large, resulting in large vibration and high heat generation, and the large vibration and heat generation of the motor will easily lead to carbon brush failure. The brush braids come out and become damaged. Contents of the invention [0003] The present ap...
