Wear sensing device for graphene carbon motor carbon brush component and use method of wear sensing device

Abstract

The invention discloses a wear sensing device for a graphene carbon motor carbon brush component. The wear sensing device comprises a first sensing mechanism and a second sensing mechanism; the secondsensing mechanism is arranged on one side of the first sensing mechanism; the first sensing mechanism is provided with a first carbon brush; the second sensing mechanism is provided with a second carbon brush; each of the first sensing mechanism and the second sensing mechanism comprises a first mounting seat; an accommodating groove is arranged on the side surface of each first mounting seat andis fixedly provided with a control mechanism, a pressure detection mechanism and an alarm mechanism inside; and a cover plate is fixedly arranged on the side surface of each pressure detection mechanism. According to the wear sensing device provided by the invention, by arranging springs and the pressure detection mechanisms, whether the first carbon brush and the second carbon brush need to be changed or not is judged through numerical values detected by the pressure detection mechanisms; compared with existing manual judgement, a judgement result of the wear sensing device is more accurate,and the condition that the first carbon brush and the second carbon are not used all when being changed, and the manpower is wasted can be effectively avoided.

Description

technical field

[0001] The invention relates to the technical field of carbon brushes, in particular to a wear sensing device for a carbon brush assembly of a graphene carbon motor and a method for using the same. Background technique

[0002] Carbon brush (Carbon brush) is also called electric brush, as a kind of sliding contact, it is widely used in many electrical equipment. Carbon brushes are mainly used in graphite, fat-impregnated graphite, and metal (copper, silver) graphite. A carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery. It is generally made of pure carbon and a coagulant. A spring presses it tightly on the rotating shaft. When the motor rotates, the electric energy is transmitted to the coil through the commutator. Because its main component is carbon, it is called a carbon brush, which is easy to wear. It should be regularly maintained and replaced, and ...
