Problems solved by technology

[0006] However, in this conventional brush support member 62, the brush powder cannot be discharged and remains inside, causing a short circuit and shortening the life of the generator.
[0007] That is, the existing brush support member 62 such as figure 1 As shown, there is no air flow around the brush in contact with the conductive ring, and it is covered by the conductive ring guide 53, etc., making it difficult to discharge the brush powder, especially when the brush powder flows into the bearing 24 and damages the bearing. Seals are provided for this, but there is still the problem of not adequately blocking

Embodiment 1

[0019] The structure of Embodiment 1 is a structure after improving the structure of the brush support member 62 , the structure of the rear bracket 21 and the seal 20 .

[0020] That is, when forming the brush supporting member 62, the cylindrical portion 62a covering the conductive ring 50 and the brush supporting portion 62b in which the brush 61 can be built in a direction perpendicular to the cylindrical portion 62a are formed, An air inlet 62c is formed on the side end surface of the cylindrical portion 62a so that the air flows into the periphery of the brush, and the shaft hole 21a that does not touch the circumferential surface of the conductive ring 50 is formed on the rear bracket 21 and the shaft hole 21a from the conductive ring 50 is formed on the rear bracket 21 The shaft hole to the first guide hole 21b formed around the cooling fan 31 is provided between the inner section of the cylindrical portion 62a of the brush support member 62 and the periphery of the sha...

Embodiment 2

[0028] The structure of Embodiment 2 is also a structure in which the brush support member 62 , the rear bracket 21 and the seal 20 have been improved.

[0029] When forming the brush supporting member 62, the cylindrical portion 62a covering the conductive ring 50 and the brush supporting portion 62b in which the brush 61 can be built in a direction perpendicular to the cylindrical portion 62a are formed. An air inlet 62c is formed on the side end surface of the cylindrical portion 62a, and an air guide groove 62d is formed on the inner side of the support portion 62b so that the air flows around the brush 61, and the rear support 21 is formed to communicate with the support. The second guide hole 21c of the air guide groove 62d of the part 62b is provided between the inner section of the cylindrical part 62a of the brush support member 62 and the shaft hole 21a on the rear bracket 21 for blocking The inner side of the bearing 24 and its outer contour rectifier 70 seal 20 for...

Abstract

This invention relates to an electric brush support device of a car AC generator. Its support part is composed of a cylindrical part covering a conduction ring and a support part with the electric brush in it vertical to the direction of the cylindrical part, an air inlet is formed at the side end of the cylinder to let air flow around the brush, a shaft hole can't contact with the surrounding of the ring is formed on the back bracket and a first leading hole is formed around the shaft hole to said cold fan and an airtight packing is set between the internal section of the cylinder and surrounding of the back bracket shaft hold for stopping air from flowing into the rectifying device.

Description

technical field [0001] The present invention relates to a brush supporting device of an alternator for automobiles, more specifically, the conductive ring part of the brush is arranged outside the rear bracket, the conductive ring part is covered and the air flows in and out, by thus assembling the improved A brush support member so that brush powder generated by the brush is easily discharged along the inside of the brush support member. Background technique [0002] Generally, an automotive alternator is composed of a stator disposed between the front and rear brackets and a rotor disposed at the center thereof. Exciting current flows through the coils of the rotor through brushes and conductive rings, and the three-phase current generated in the stator coils The phase alternating current is rectified by the rectifier on the rear bracket to become direct current. [0003] In existing alternators so used, the brush assembly has features such as figure 1 structure shown. ...
