Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 3 As shown, a brush holder assembly of the present invention includes a brush plate 7, and the center of the brush plate 7 is provided with an assembly hole 7-1 for installing the steering gear. The steering gear is cylindrical and installed in the assembly hole 7-1 And can rotate freely.

[0022] Two brush boxes 8 are arranged symmetrically on both sides of the assembly hole 7 - 1 , and the brush boxes 8 are pressed and fixed on the surface of the brush plate 7 . Inside each brush box 8, a brush 1 that can move back and forth is arranged along the radial direction of the assembly hole 7-1. The top surface of the brush 1 has a brush braid 1-1 for connecting the power supply. The brush spring 2, the end of the brush spring 2 leans against the inner wall of the end of the brush box 8, and the front end leans against the brush 1, and the brush ...

Abstract

The invention discloses a brush carrier assembly which comprises a brush plate, an assembly hole is formed in the center of the brush plate, brush boxes are symmetrically arranged at the two sides of the assembly hole, electric brushes are arranged in the brush boxes, the electric brushes are provided with brush litzendraht wires, electric brush springs are arranged at the tail ends of the electric brushes, the brush plate is provided with a clamping seat, a strip-shaped groove is formed in the clamping seat, two sets of elastic clamping bodies made of conductive materials are symmetrically arranged at the two sides of the strip-shaped groove, each elastic clamping body is connected with a sensor or an indicating lamp, the sensors or the indicating lamps are connected with brush litzendraht wires, a boss is arranged in the portion, close to the tail end, of the electric brush, and the boss extends into the strip-shaped groove and is clamped between the two elastic clamping bodies, and the elastic clamping bodies of the clamping boss and the sensor or the indicating lamp connected with the elastic clamping bodies of the clamping boss form a conductive loop through the electric brushes. The problems that the electric brushes are biased due to the friction force of a commutator and the abrasion state of the electric brush cannot be obtained in real time are solved.

Description

technical field [0001] The invention relates to a brush holder assembly for a brush motor. Background technique [0002] The brush holder of the existing brushed motor generally puts the brush in the brush box, and the brush is contacted with the commutator by the elastic force of the spring at the end of the brush to make the motor run. [0003] The current structure has disadvantages: due to friction, the commutator will have a tangential friction force in the circumferential direction on the brush during operation, which will cause the brush to be inclined in the brush box, which will bring There are two unfavorable factors: ①The contact between the end face of the brush and the commutator is unstable, sparks are easily generated, and the wear of the brush is unstable, which affects the service life of the motor; ②Because the brush is inclined during operation, the spring force is horizontal , As a result, the brush will swing back and forth in the brush box and produce ...
