Pluggable brush holder brush box and installation method thereof

Abstract

The invention discloses a plug-in brush holder brush box and a mounting method thereof, and relates to the field of motor brush holder brush boxes, the plug-in brush holder brush box comprises a brush box, a brush holder and a brush carrier, the inner wall of the brush box is fixedly connected with a plurality of groups of connecting feet, connecting grooves are formed in the connecting feet, two opposite groups of connecting grooves are uniformly provided with heating deformation bins on the opposite surfaces of the inner walls, and the heating deformation bins are connected with the brush box. The top end of the inner wall of the brush holder cavity is fixedly connected with a hollow fixing column, the lower end of the fixing column is slidably connected with a top column, the bottom end of the top column is connected with the top end of a carbon brush seat movably arranged in the brush holder cavity, the top end of the top column is provided with an adjusting spring in the fixing column, and the top end of the adjusting spring is in contact with a bottom foot of a screw. The screw rod is in threaded connection with the top end of the brush holder and the upper part extends out of the brush holder. According to the invention, the efficiency of replacing the carbon brush is greatly improved, the brush box and the brush holder can be in stable contact when the motor works, and the purpose of conveniently increasing or reducing the pressure between the carbon brush and the collector ring is achieved.

Description

technical field [0001] The invention relates to the field of motor brush holding brush boxes, in particular to a plug-in brush holding brush box and an installation method thereof. Background technique [0002] During the operation of the generator, the excitation device rectifies the alternating current obtained from the generator outlet into the direct current with the required parameters. It is installed in the brush holder, so the entire operating condition of the brush holder affects the running effect of the carbon brush. [0003] Most of the existing motor brush holders and brush boxes are fixedly connected to the brush holder by bolts, and gaps are easily formed at the connection between the brush holder and the brush box, which causes the brush holder to vibrate in the brush box when the motor is working, causing the carbon rods to not wear out. It is uniform and generates relatively large noise. Since the brush holder is fixed in the brush box, it is more troubles...

AI Technical Summary

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide a plug-in brush holder brush box and its installation method to solve the problem that the existing motor brush holder brush box is prone to gaps at the connection between the brush holder and the brush box, and it is relatively difficult to replace the carbon brush. Troublesome, and at the same time cannot conveniently control the technical problem of the pressure between the carbon brush and the collector ring
