본 고안은 차량용 교류발전기의 슬립링 가이드에 관한 것으로 특히 브러쉬와 슬립링과의 회전마찰로 생기는 브러쉬 마모분에 의해 슬립링 가이드 내에서 단락되는 것을 방지한 교류발전기의 슬립링 가이드에 관한 것이다.The present invention relates to a slip ring guide of an automotive alternator, and more particularly, to a slip ring guide of an alternator which is prevented from being short-circuited in the slip ring guide by brush wear caused by rotational friction between the brush and the slip ring.
차량용 교류발전기는 차량 내의 전기시스템과 밧데리에 전류를 공급하게 되는 것으로 그 구조는 제1도에서와 같이 풀리(11)와 회전자(12)가 장착된 회전자축(13)과 상기 회전축(13)과 풀리(11) 사이에 설치된 후론트베어링(14)과 상기 풀리 반대측에 설치된 리어베어링(15)과 상기 회전자(12)의 외주부를 감싸는 고정자(16), 회전자(12)와 고정자(16)를 지지하는 1쌍의 브래킷(17)과 브래킷(17) 내측에 설치된 정류기(18) 및 전압조정장치(19)로 구성되고 회전자(12)와 리어베어링(15) 사이에는 제2도에서와 같이 브러쉬(2)가 브러쉬홀드(5) 내에서 스프링(4)으로 탄지되게 고정지지되고, 하부에 슬립링(1)이 슬립링가이드(3)에 감싸여 브러쉬(2)와 섭동하며 전류를 공급하게 되어 있는데 이때 슬립링가이드(3) 내에는 고정체인 브러쉬(2)와 회전체인 슬립링(1)이 섭동함에 따라 회전마찰이 발생되어 브러쉬(2) 마모분이 발생하게 되고 상기 브러쉬 마모분이 슬립링 가이드(3)의 안쪽 한 곳에 집진됨에 따라 +축 브러쉬와 -축 브러쉬간 또는 +축 브러쉬와 브라켓 간에 단락 현상이 발생하는 불량이 발생하게 된다.The vehicle alternator supplies electric current to the electric system and the battery in the vehicle. The structure of the vehicle alternator includes the rotor shaft 13 and the rotating shaft 13 on which the pulley 11 and the rotor 12 are mounted, as shown in FIG. And a front bearing 14 installed between the pulley 11 and the rear bearing 15 provided on the opposite side of the pulley and the stator 16 surrounding the outer circumference of the rotor 12, the rotor 12, and the stator 16. It consists of a pair of brackets 17 and a rectifier 18 and a voltage regulating device 19 installed inside the brackets 17 for supporting the shaft, and between the rotor 12 and the rear bearing 15 in FIG. Likewise, the brush 2 is firmly supported by the spring 4 in the brush holder 5, and the slip ring 1 is wrapped in the slip ring guide 3 at the bottom to perturb the brush 2 and the electric current. At this time, the slip ring guide (3) in the slip ring guide (3) and the rotating ring slip ring (1) as perturbation Abrasion of the brush (2) occurs due to total friction, and the brush wear is collected in one place of the slip ring guide (3), causing a short circuit between the + -axis brush and the -axis brush or between the + -axis brush and the bracket. Defects will occur.
본 고안은 이와 같은 점을 감안하여 안출한 것으로 브러쉬와 슬립링의 회전마찰로 생기는 브러쉬 마모분을 분산집진 될 수 있게 함에 따라 단락되는 불량을 방지할 수 있도록 한 것이다.The present invention has been devised in view of such a point to prevent the short-circuit defect as the brush wear caused by the rotational friction of the brush and the slip ring can be dispersed and collected.
이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.
본 고안은 회전자(12)와 고정자(16)로 이루고 회전자(12)에 브러쉬(2)와 슬립링(1)이 섭동하며 전류를 공급하는 교류발전기에 있어서, 브러쉬(2)와 섭동하며 회전자(12)에 전류를 공급하는 슬립링(l)의 슬립링 가이드(3) 내주면에 다수의 턱(6)을 형성시킨 구조이다.The present invention consists of a rotor (12) and a stator (16), the brush (2) and the slip ring (1) perturbing the rotor 12 in the alternator to supply a current, perturbing with the brush (2) A plurality of jaws 6 are formed on the inner circumferential surface of the slip ring guide 3 of the slip ring 1 for supplying current to the rotor 12.
제3도는 본 고안의 슬립링 가이드(3) 내에 슬립링(1)과 브러쉬(2)가 섭동되는 구조를 나타낸 구성단면도로써 슬립링 가이드(3) 내에 슬립링(1)이 브러쉬(2)와 섭동하게 내장되고, 브리쉬(2)는 브러쉬홀드(5) 내에 스프링(4)으로 탄지되게 고정지지되며, 슬립링 가이드(3) 내주면에는 브러쉬(2)와 슬립링(1)의 마찰에 의해 발생되는 브러쉬가루가 분산축적될 수 있도록 수평(축)방향의 턱(6)을 1개 이상 구비하게 되어 있다.3 is a cross-sectional view showing a structure in which the slip ring 1 and the brush 2 are perturbed in the slip ring guide 3 of the present invention, and the slip ring 1 in the slip ring guide 3 is separated from the brush 2. Perturbingly embedded, the bristle (2) is firmly supported by the spring (4) in the brush holder (5), the inner peripheral surface of the slip ring guide (3) by friction between the brush (2) and the slip ring (1) At least one jaw 6 in the horizontal (axial) direction is provided so that the generated brush dust can be accumulated and accumulated.
이와같이 구성된 본 고안은 발전기가 발전을 하기 위해서는 회전자(12)가 자화되어 고정자(16)내에서 회전하면서 고정자코일에 기전력을 유기하게 되는데 이때 회전하는 회전자(12)에 자화시킬 수 있는 전류를 공급하기 위해서는 회전하는 슬립링(1)에 브러쉬(2)가 섭동하며 전류를 공급하게 된다. 이때 슬립링(1)과 브러쉬(2)가 섭동하면서 발생되는 브러쉬 마모분이 슬립링 가이드(3) 내에 집진되면서 단락되는 불량이 발생되는데 슬립링 가이드(3) 내주면에 브러쉬 마모분이 골고루 분산되어 쌓일 수 있는 턱(6)을 설치함으로써 브러쉬 마모분이 한 곳에만 집중적으로 쌓여서 생기는 불량을 방지하게 된다.The present invention configured as described above is to generate an electromotive force in the stator coil while rotating the rotor 12 in the stator 16 to magnetize the generator, the current that can be magnetized to the rotating rotor 12 In order to supply, the brush 2 is perturbed and supplies a current to the rotating slip ring 1. At this time, the brush wear caused by the perturbation of the slip ring 1 and the brush 2 is collected in the slip ring guide 3, and a short circuit occurs. The brush wear is evenly distributed on the inner circumferential surface of the slip ring guide 3. By installing the jaw (6) to prevent the defect caused by the intensive accumulation of brush wear in only one place.
이상에서와 같이 본 고안은 브러쉬와 슬립링의 회전마찰에 의해 생긴 브러쉬 마모분을 골고루 분산하여 집진하므로 브리쉬 마모분이 한쪽에 쌓여서 생길 수 있는 단자사이의 단락이나 단자와 브래킷과의 접지 등에 의한 불량을 방지할 수 있는 효과가 있다.As described above, the present invention evenly distributes and collects the brush wear caused by the rotational friction of the brush and the slip ring, so that a short circuit between the terminals of the bristle wear and the grounding between the terminal and the bracket may occur. There is an effect that can prevent.
