Generator regulator carbon brush holder convenient to clean

Abstract

According to the generator regulator carbon brush holder convenient to clean, the annular scrap collecting groove body is formed in the bottom of the cylinder part, the annular scrap collecting groove body is located on the outer side of a slip ring of a generator rotor after installation, and when a generator works, the generator rotor rotates at a high speed, so that the slip ring on the generator rotor makes contact friction with a carbon brush; after a long time, carbon powder generated by abrasion of the carbon brush is scattered into the inner cavity of the annular scrap collecting groove body through the centrifugal force of rotation of the slip ring of the generator rotor, so that the carbon powder is prevented from being accumulated or adhered to the generator and other electrical elements or a bearing chamber, and normal operation of the generator is guaranteed. A cleaning banister brush is rotationally arranged on the annular scrap collecting groove body, and a tiny gap is formed between the cleaning banister brush and the generator rotor slip ring, so that after carbon powder generated by abrasion of a carbon brush adheres to the outer surface of the slip ring, the size of the outer surface of the slip ring is increased, and the slip ring makes contact with the cleaning banister brush; and therefore, the cleaning banister brush can clean the carbon powder adhered to the outer surface of the slip ring.

Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a generator regulator carbon brush holder which is easy to clean. Background Art

[0002] The automobile generator regulator is an electronic component, also known as a voltage regulator. Its main function is to ensure that the automobile battery obtains the appropriate charging current and voltage by automatically adjusting the output voltage and current of the generator, thereby ensuring the normal operation of the automobile electrical system. The existing voltage regulator is provided with a carbon brush holder, and two carbon brush holes are arranged in parallel in the carbon brush holder for slidingly installing carbon brushes. The carbon brush is a conductive part made of carbon material, which is used to establish an electrical connection with the rotating part of the generator (usually the rotor). At present, when the generator rotates, due to the high-speed rotation of the generator rotor, the slip ring on it contacts and rubs with the carbon brush on the voltage regulator. Since the carbon brush is made of carbon material and is a consumable part, during long-term use, the friction between the carbon brush and the slip ring will cause it to produce carbon chips or carbon powder, which will accumulate or adhere to the generator and other electrical components or the bearing chamber, thereby causing damage to other electrical components or bearings, and further affecting the normal operation of the generator.

The carbon brush 10 is blocked; an annular chip trough body 4 is fixedly provided at the bottom of the barrel 3, the annular chip trough body 4 and the barrel 3 are an integrally formed structure, and the inner cavity of the annular chip trough body 4 is connected with the inside of the barrel 3, and the inner side wall of the annular chip trough body 4 is arranged close to the generator rotor slip ring 8. Specifically, the inner diameter of the inner cavity of the annular chip trough body 4 is smaller than the inner diameter of the barrel 3, and the inner diameter of the inner cavity of the annular chip trough body 4 is slightly larger than the outer diameter of the generator rotor slip ring 8. This design makes the inner cavity of the annular chip trough body 4 extend toward the generator rotor slip ring 8, thereby making the carbon brush 10 contact and rub against the high-speed rotating rotor slip ring The carbon powder generated after wiping can be scattered into the inner cavity of the annular chip trough body 4 to a greater extent. In addition, the outer diameter of the inner cavity of the annular chip trough body 4 is larger than the outer diameter of the barrel 3. This design can increase the inner cavity volume of the annular chip trough body 4, so that the inner cavity of the annular chip trough body 4 can have enough space to accommodate the carbon powder generated by the wear of the carbon brush 10, and the inner side wall height of the inner cavity of the annular chip trough body 4 is set to be smaller than the outer side wall height of the inner cavity of the annular chip trough body 4.

In the inner cavity; In addition, a plurality of reinforcing ribs 7 are fixedly arranged between the annular chip trough body 4 and the barrel 3 along the circumferential direction of the barrel 3, which can enhance the structural strength of the annular chip trough body 4, and the top of the outer wall of the inner cavity of the annular chip trough body 4 is arranged as an inclined surface 41, and the design of the inclined surface 41 makes it possible for the carbon powder to be poured out more smoothly from the inclined surface 41 of the annular chip trough body 4 when the barrel 3 is removed from the carbon brush holder 2 and the carbon powder in the barrel 3 is dumped; A plurality of vertically arranged cleaning soft brushes 6 are arranged at the top of the inner wall of the annular chip trough body 4 along its circumferential rotation, and the gap size between the outer edge of the cleaning soft brush 6 and the generator rotor slip ring 8 is 0.1-1mm, so that when the carbon powder produced by the wear of the carbon brush 10 adheres to the outer surface of the generator rotor slip ring 8, the outer surface size of the generator rotor slip ring 8 increases and contacts with the cleaning soft brush 6, so that the cleaning soft brush 6 can clean the carbon powder adhered to the outer surface of the generator rotor slip ring 8; a protective cover plate 5 is installed on the top of the barrel 3, a clamping block 52 is fixed at the bottom of the protective cover plate 5, and a clamping groove 32 is opened on the top of the barrel 3. The position setting and size of the clamping block 52 and the clamping groove 32 are corresponding. The protective cover plate 5 is connected to the barrel 3 through the clamping assembly of the clamping block 52 and the clamping groove 32.

[0022] In summary, it can be known that by setting the annular chip collecting trough body 4 at the bottom of the cylinder 3, and after installation, the annular chip collecting trough body 4 is located outside the generator rotor slip ring 8, so that when the generator is working, the generator rotor rotates at a high speed so that the slip ring thereon contacts and rubs with the carbon brush 10, and the carbon powder generated by the wear of the carbon brush 10 after a long time is scattered into the inner cavity of the annular chip collecting trough body 4 through the centrifugal force of the rotation of the generator rotor slip ring 8, thereby avoiding the accumulation or adhesion of carbon powder in the generator and other electrical components or the bearing chamber, thereby ensuring the normal operation of the generator; and by rotating on the annular chip collecting trough body 4 The cleaning soft brush 6 and the tiny gap between the cleaning soft brush 6 and the generator rotor slip ring 8 enable the carbon powder produced by the wear of the carbon brush 10 to adhere to the outer surface of the generator rotor slip ring 8, and the outer surface size of the generator rotor slip ring 8 increases and contacts with the cleaning soft brush 6, so that the cleaning soft brush 6 can clean the carbon powder adhered to the outer surface of the generator rotor slip ring 8, and the cleaned carbon powder can also be scattered into the inner cavity of the annular chip collecting trough body 4 by the centrifugal force of the rotation of the generator rotor slip ring 8, so as to avoid the cleaned carbon powder from accumulating in the generator.
