Belt type grinding device for shaft for electric power overhaul

Abstract

The invention discloses a belt type grinding device for a shaft for electric power overhaul. The belt type grinding device comprises a mounting bottom plate, a transmission part, a bracket part and aclamping part; the bracket part comprises a first supporting frame and a second supporting frame; the first supporting frame and the second supporting frame are connected through a fastener; a first guide wheel is arranged on one side of the first supporting frame; a second guide wheel and a third guide wheel are arranged on the second supporting frame; and a guide wheel bracket part is arranged on the outer side face of the first supporting frame. According to the belt type grinding device, the clamping part is used for fixing and limiting, then a polishing abrasive belt is used for polishingthe welding position of a large shaft, excessive polishing is prevented, and the strength of the large shaft is prevented from being reduced; and meanwhile, the problem that assembly cannot be conducted due to the fact that polishing is insufficient can be solved, the polishing effect is guaranteed, the polishing efficiency is improved, and the use convenience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a belt-type grinding device for electric power maintenance. Background technique [0002] The generator set has a large capacity, can run in parallel and lasts for a long time, and can also run independently. During long-term operation, the generator shaft rotates at a high speed and bears a large torque, which inevitably causes wear on the transmission shaft After these situations arise, it is necessary to seek good technology and repair process to solve them. At present, repair welding machine processing, electric brush plating and other technologies are mostly used for repair. However, after repair, due to welding heat deformation or welding residue or protrusions, etc., assembly is caused. At present, manual hand-held grinding wheels are used for grinding the repaired large shaft. The machine is used for grinding, but the degree of grinding is too light, res...

Problems solved by technology

At present, repair welding machine processing, electric brush plating and other technologies are mostly used for repair. However, after repair, due to welding heat deformation or welding residue or protrusions, etc., assembly is caused. At present, manual hand-held grinding wheels are used for grinding the repaired large shaft. Machine grinding, but the degree of grinding is too light, resulting in the failure of assembly, grinding too heavy, will reduce the strength of the worn part, greatly increasing the uncontrollability of the work
