Problems solved by technology

Because it is mostly made of graphite, it is also called carbon brush. The brush is mostly assembled on the commutator or slip ring. It is a sliding contact body and needs to be smooth, wear-resistant, and good in conductivity. , they are either partially metal parts (copper, silver, molybdenum), rich or enti

[0029] Example

[0030] reference Figure 1-5 In this embodiment, a brush adjustment device is proposed, which includes a bottom plate 1. Two side plates 2 are slidably mounted on the top of the bottom plate 1. The sides of the two side plates 2 close to each other are provided with slide grooves 3. Sliders 4 are slidably installed in the chute 3, and the same mounting plate 5 is slidably installed on the side of the two sliders 4 close to each other. The mounting plate 5 is provided with a mounting hole 6, and the mounting hole 6 is movably installed with a sleeve 7. One end of the spring 8 is fixedly installed in the casing 7, and the other end of the spring 8 is fixedly installed with a brush 9. The bottom of the mounting plate 5 is fixedly installed with two connecting blocks 12, and the bottom of the two connecting blocks 12 is fixedly installed with The same connecting plate 14, the top of the connecting plate 14 is fixedly installed with the first conductive block 15, and...

Abstract

The invention discloses a brush adjusting device and method. The brush adjusting device comprises a bottom plate, wherein two side plates are slidably mounted on the top of the bottom plate; the adjacent sides of the two side plates are provided with sliding slots; slide blocks are slidably mounted in the two sliding slots; the same mounting plate is slidably mounted on the adjacent sides of the two slide blocks, and is provided with a mounting hole; a sleeve is movably mounted in the mounting hole; one end of a spring is fixedly mounted in the sleeve; a brush is fixedly mounted on the other end of the spring; two connecting blocks are fixedly mounted on the bottom of the mounting plate; and the same connecting plate is fixedly mounted on the bottoms of the two connecting blocks. The brushadjusting device facilitates the adjustment of the tightness of the spring, avoids a phenomenon of poor contact of the brush, can remind a user when the spring reaches a limit, can adapt to differentsizes of brushes by adjusting the distance between the two side plates, and can easily remove and replace the brush.

Description

technical field [0001] The invention relates to the technical field of brush adjustment, in particular to a brush adjustment device and an adjustment method thereof. Background technique [0002] The brush (Brush) is an important component of the motor, responsible for conducting current between the rotating part and the stationary part. Because it is mostly made of graphite, it is also called carbon brush. The brush is mostly assembled on the commutator or slip ring. It is a sliding contact body and needs to be smooth, wear-resistant, and good in conductivity. , they are either partially metal parts (copper, silver, molybdenum), rich or entirely made of metal, after the brushes are worn for a long time, the elasticity of the springs connected to them is weakened, which in turn makes the brushes and commutator Poor contact makes the brush unusable, so we have withdrawn a brush adjustment device and its adjustment method to solve the above problems. Contents of the inventi...
