Adjustable flexible electric brush and use method thereof

Abstract

The invention discloses an adjustable flexible electric brush and a use method thereof. The adjustable flexible electric brush comprises an electric brush, an outer ring and a proximity kit, the electric brush comprises three groups of electric brush main bodies disposed in an annular array, the outer contour of the electric brush main body is of an arc-shaped plate-like structure, a fixing protrusion is disposed above the electric brush main body, electric brush grooves are formed in two sides of the fixing protrusion, a plurality of fixing holes disposed in a rectangular array are formed ina plane of a top end of the fixing protrusion, the outer ring is disposed at the outside of the electric brush, the outer ring comprises a ring frame having an outer contour in a circular ring structure, three groups of positioning ridge grooves are uniformly distributed on a circular ring surface at the outside of the ring frame, the contour of the cross section of the positioning ridge groove has a triangular structure, ring mounting holes are formed in the ring grooves on one of the sides of the three groups of positioning ridge grooves, the ring mounting holes are counterbores, the ring mounting holes extend into a space formed by the positioning ridge grooves, and wire grooves are formed in the end faces of adjacent ring frames of the ring mounting holes. By adoption of the adjustableflexible electric brush and the use method thereof, a relative position between the electric brush and a motor can be determined, and the adjustable flexible electric brush and the use method thereofare suitable for widespread use.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to an adjustable flexible brush and a using method thereof. Background technique [0002] Motor (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. It can be divided into DC motor and AC motor according to the type of working power supply. The brush is an important part of the motor. The components are responsible for conducting current between the rotating part and the stationary part. Because they are mostly made of graphite, they are also called carbon brushes. [0003] Conventional brushes often use springs to press the brushes directly to the commutator on the electrode spindle, and the springs directly act on the carbon brushes to press the carbon brushes to the commutator. The stretching amount of the spring ...

Problems solved by technology

[0003] Conventional brushes often use springs to press the brushes directly to the commutator on the electrode spindle, and the springs directly act on the carbon brushes to press the carbon brushes to the commutator. The stretching amount of the spring on the carbon brush keeps increasing, and the force acting on the carbon brush is different from the force acting on the carbon brush when the stretching amount of the spring is small, which may cause the carbon brush to fail to press the commutator, resulting in abnormal operation of the motor
