Maintenance-type carbon brush pressure compression spring

Abstract

The invention discloses a maintenance-type carbon brush pressure compression spring, belongs to the field of basic electrical components, specifically relates to a maintenance-type carbon brush pressure compression spring in order to solve a problem that during the operation of a carbon brush, when the pressure of an original carbon brush compression spring is insufficient and is required to be adjusted, no carbon brush compression spring with pressure greater than the pressure of the original carbon brush compression spring by 1 to 10 percent can replace the original carbon brush compressionspring. A technical solution to the problem is characterized by providing a new carbon brush compression spring type besides the original carbon brush compression spring type, wherein the pressure ofthe type of carbon brush compression spring is greater than the pressure of each type of original carbon brush compression spring by one to ten percent. The maintenance-type carbon brush pressure compression spring is used when the carbon brush pressure is insufficient and needs to be solved by adjusting the pressure of the carbon brush compression spring.

Description

technical field [0001] The utility model relates to a carbon brush pressure compression spring of a maintenance type motor, which belongs to the field of basic electrical components. Specifically relates to a maintenance type motor carbon brush pressure compression spring Background technique [0002] At present, my country's motors, including generators, and carbon brush compression springs are single-sided and double-sided respectively. The pressure of each single-turn style is continuously shortened during the working process, and the pressure of the compression spring is continuously reduced. At the same time, due to daily maintenance, the length of the carbon brush on the same brush holder will be different, and the pressure on the carbon brush will be different. They are different from each other. For example, if sparks are caused by the friction between the carbon brush and the motor slip ring, it may cause a ring fire phenomenon in severe cases. At the same time, th...
