Generator motor collector ring carbon brush polishing device

Abstract

The invention discloses a generator motor collector ring carbon brush polishing device which comprises a carbon brush polishing device base and a carbon brush polishing device rail fixed to the top end of the carbon brush polishing device base, a sliding frame is arranged on the carbon brush polishing device rail, and a spring support is fixed to the sliding frame; a through groove used for containing a carbon brush is formed in the sliding frame, a constant-force spring used for fixing the carbon brush is arranged in the spring support, a limiting buckle is arranged on one side of the carbon brush, a collecting box is arranged at the top end of the carbon brush polishing device base, two handles are fixed to the outer wall of the collecting box, a partition plate is arranged in the collecting box, and the carbon brush polishing device is arranged in the partition plate. Protruding blocks are fixed to the two sides of the partition plate correspondingly, and sliding grooves matched with the protruding blocks are formed in the two symmetrically-arranged vertical inner walls of the collecting box correspondingly. According to the generator motor collector ring carbon brush polishing device, the carbon brush can be fixed conveniently, and scraps can be collected conveniently.

Description

technical field [0001] The invention belongs to the technical field of carbon brushes for collector rings of generator motors, in particular to a carbon brush grinding device for collector rings of generator motors. Background technique [0002] The collector ring carbon brush of the generator motor is used in the excitation system to input the excitation current to the rotor of the generator motor to provide the excitation current for the generator motor. If the carbon brush is in poor contact with the slip ring of the collector ring after replacement, it will cause ignition or cutting of the carbon brush, resulting in a large amount of carbon powder deposition, which will affect the normal use of the equipment. [0003] Therefore for this present situation, there is an urgent need to design and produce a generator motor slip ring carbon brush grinding device to meet the needs of actual use. Contents of the invention [0004] The purpose of the present invention is to pr...
