Description

모터의 브러시홀더Brush holder of the motor

일반적으로 차량용 발전기를 포함한 모터는 회전자와 고정자로 구성되어 있고 상기 회전자의 일단에는 정류를 위한 코뮤테이터가 설치되어 있으며 이 회전되는 코뮤테이터와 외부장치(레귤레이터등)와의 전기적 접속을 위하여 통상 카본재질의 브러시를 설치하여 사용하고 있고, 상기 브러시는 코뮤테이터와 면접촉을 하면서 통전이 이루어지도록 되어 있다.In general, a motor including a generator for a vehicle is composed of a rotor and a stator, and a commutator for rectifying is installed at one end of the rotor, and usually carbon is used for electrical connection between the rotating commutator and an external device (regulator, etc.). A brush made of a material is installed and used, and the brush is made to conduct electricity while making surface contact with the commutator.

또, 상기와 같이 작용하는 브러시는, 상기 코뮤테이터와 마찰하면서 접속하기 때문에 이의 안정적인 설치와 마모된 상태에서도 쉽게 접속시키기 위하여 상기 브러시를 내장하는 브러시홀더를 구비하고 있고 이 브러시홀더에는 탄력수단을 구비하고 있다.In addition, the brush acting as described above is provided with a brush holder incorporating the brush for easy connection even in a worn state, since the brush is connected with friction with the commutator, and the brush holder has elastic means. Doing.

한편, 상기와 같이 구성되는 종래의 브러시홀더는 그 내부에 스프링 등의 탄력수단이 자유상태로 삽입되어 있고 이 탄력수단의 탄력을 받는 상태로 브러시가 삽입 설치되어 있으며 상기 탄력수단은 브러시의 중심부에서 탄발력을 발휘하도록 구성되어 있었다.On the other hand, the conventional brush holder is configured as described above, the elastic means such as a spring is inserted into the free state therein, the brush is inserted into the state receiving the elastic means of the elastic means is installed in the center of the brush It was configured to exert elasticity.

그러나, 상기와 같은 종래의 것은 브러시를 브러시홀더내에 삽입시킨 상태에서 탄력수단인 스프링이 브러시의 중심부에서만 탄력작용을 하기 때문에 상기 브러시의 탄력중심이 편심되는 폐단이 있었으며 상기 브러시의 편심으로 인하여 코뮤테이터와의 접속이 불안정하게 되고 또, 브러시가 편마모되는 결점이 있었으며 상기 편마모가 심하거나 모터의 급격한 부하가 걸리게 될 경우 브러시가 이를 이겨내지 못하고 파손되는 일이 종종 발생되는 문제점이 있었다.However, such a conventional method has a closed end in which the elastic center of the brush is eccentric because the spring, which is the elastic means, acts only at the center of the brush while the brush is inserted into the brush holder, and the commutator is caused by the eccentricity of the brush. There was a drawback in that the connection with the instability was unstable, and the brush was unevenly worn, and when the uneven wear was severe or a sudden load of the motor was applied, the brush often failed to overcome it and was broken.

본 고안은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 브러시가 탄력설치되는 브러시홀더에 2단계의 탄력수단과 가이드수단을 구비하고 이들로써 브러시홀더에 설치되는 브러시를 안정된 상태로 탄력지지시키며 브러시의 편심을 방지하여 편마모를 방지하면서 모터내에 설치되는 코뮤테이터와의 상호 접속이 안정적이면서 확실하게 이루어질 수 있도록 한 모터의 브러시홀더를 구성한 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the conventional problems as described above, the brush holder is provided with a resilient means and guide means of the two stages in the brush holder is installed elastically support the elasticity of the brush installed in the brush holder in a stable state The brush holder of the motor is configured to stably and securely interconnect the commutator installed in the motor while preventing eccentric wear of the brush, which will be described in detail with reference to the accompanying drawings. Is as follows.
