본 고안은, 자동차 등에 사용되는 시동전동기의 방수장치에 있어서, 특히 앞면브래킷의 방수수단에 관한 것이다.The present invention relates to a waterproofing device of a starter motor for use in an automobile or the like, and more particularly, to a waterproofing means of a front bracket.
제 3 도 및 제 4 도는, 종래의 시동전동기의 방수장치를 나타내는 단면도 및 정면도이다. 도면에 있어서, 1은 직류전동기이고 다음과 같이 구성되어 있다. 2는 계철이고, 계자극(界磁極)(3)이 부착되어 있다. 4 및 5는 계철(2)에 고정되는 뒷면브래킷 및 앞면브래킷, 6은 전기자이고 이의 회전축(7)이 베어링(8) 및 (9)를 사이에 두고 뒷면브래킷(4) 및 앞면브래킷(5)에 의해 지지되어 있다. 10은 뒷면브래킷(4)에 장착된 브러시장치이다.3 and 4 are cross-sectional views and front views showing a waterproofing device of a conventional starting motor. In the figure, 1 is a direct current motor and is configured as follows. 2 is yolk, and a field stimulus 3 is attached. 4 and 5 are the rear bracket and the front bracket fixed to the yoke (2), 6 is the armature and its rotation shaft (7) between the bearing (8) and (9) between the rear bracket (4) and the front bracket (5) Is supported by 10 is a brush device mounted to the rear bracket (4).
다음에, 11은 회전축(7)에 전진과 후퇴가 가능하도록 지지된 오버러닝클러치이고, 클러치의 전단부에 피니언(12)가 일체적으로 형성되어 있다. 13은 회전축(7)에 고정된 스토퍼이고, 전진된 피니언(12)를 저지시킨다. 14는 전자스위치이고, 전자코일(도시생략)이 통전되며 플런져(15)를 안쪽으로 자지흡인하고, 훅(16)을 같은 방향으로 이동시킨다. 17은 지점부(17a)를 중심으로 훅(16)에 의해 회전되고 시프트레버로 오버 러닝 클러치(11)를 전진과 후퇴시킨다. 앞면 브래킷(5)에는 피니언(12)부의 아래쪽에 개구부(5a)와, 뒤쪽 하부에 물빠지는 구멍(5b)이 마련되어 있다.Next, 11 is an overrunning clutch supported by the rotational shaft 7 so that forward and backward movement is possible, and the pinion 12 is integrally formed in the front end of the clutch. 13 is a stopper fixed to the rotational shaft 7 and blocks the advanced pinion 12. 14 is an electronic switch, an electromagnetic coil (not shown) is energized, the plunger 15 cocks inside, and the hook 16 is moved in the same direction. 17 is rotated by the hook 16 about the point portion 17a and moves the overrunning clutch 11 forward and backward with the shift lever. The front bracket 5 is provided with the opening part 5a in the lower part of the pinion 12 part, and the hole 5b which drips in the lower back part.
다음에 동작에 대해 설명한다.Next, the operation will be described.
도면과 같이 정지상태에 있는 시동전동기에 있어서 전자스위치(14)의 전자코일에 통전되면, 플런저(15)에 의해 훅(16)이 안쪽으로 이동되고, 시프트레버(17)을 반시계방향으로 회전시킨다.As shown in the figure, when the electromagnetic coil of the electronic switch 14 is energized in the starting motor in the stationary state, the hook 16 is moved inward by the plunger 15, and the shift lever 17 is rotated counterclockwise. Let's do it.
이에 의하여, 오버러닝클치(11)이 전진이동되고 피니언(12)가 기관의 링 기어에 물린다. 이때 동시에 전자스위치(14)의 동작에 의해, 가동접점이 고정접점(각각 도시생략)에 접촉하고 주회로를 폐로 시키고, 전기자(6)이 회전하여 피니언(2)를 통하여 링기어를 시동회전시킨다.As a result, the overrunning clutch 11 is moved forward and the pinion 12 is bitten by the ring gear of the engine. At the same time, by the operation of the electronic switch 14, the movable contact comes into contact with the fixed contact (not shown), the main circuit is closed, and the armature 6 rotates to start and rotate the ring gear through the pinion 2. .
상기와 같은 종래의 사용전동기의 방수장치에 있어서는, 앞면브래킷(5)의 개구부(5a)로부터 물보라등이 침입할 경우, 보통은 물빠지는 구멍(5b)를 통해서 배수된다. 그러나, 배수되지 못할 경우는, 계철(2), 뒷면브래킷(4)내로 물이 침입하고, 절연을 해치기도 하고, 브러시를 고차기키기도 하여 시동전동기의 동작 불량을 야기시키는 문제점이 있었다.In the waterproof device of the conventional use electric motor as described above, when a spray or the like intrudes from the opening portion 5a of the front bracket 5, it is usually drained through the water draining hole 5b. However, when the water cannot be drained, water penetrates into the yoke 2 and the rear bracket 4, insulates the insulation, causes the brush to be kicked high, and causes a malfunction of the starting motor.
본 고안은, 이와 같은 문제점을 해결하기 위해 이루어진 것으로 앞면브래킷의 개구부로부터의 물의 침입을 억제하고 물빠지는 구멍을 통해서 배수가 이루어지도록 하고, 전동기동작불량을 없앤 시동전동기의 방수장치를 얻는 것을 목적으로 하고 있다.The present invention has been made to solve the above problems, and the purpose of the present invention is to prevent water from entering the opening of the front bracket, to drain the water through the draining hole, and to obtain a waterproofing device of the starter motor, which eliminates the malfunction of the motor. Doing.
본 고안에 관한 시동전동기의 방수장치는, 앞면브래킷의 피니언부에 대한 하방 위치에 개구부에, 피니언의 외경과 근소한 간극을 두고 방수벽을 설치하고, 이 방수벽의 저부에 배수구멍을 설치한 것이다. 본 고안에 있어서는, 앞면브래킷의 개구부에 외부로부터의 물보라 등을 맞더라도, 방수벽에 의해 침입이 억제된다.The waterproofing device of the starter motor according to the present invention is provided with a watertight wall in the opening at a position below the pinion of the front bracket with a slight gap between the outer diameter of the pinion and a drainage hole at the bottom of the watertight wall. . In the present invention, intrusion is suppressed by the waterproof wall even when splashing from the outside hits the opening of the front bracket.
피니언과 방수벽의 간극을 통해 침입한 물은 저부의 배수구멍을 통해서 배출된다. 그리고 남은 물은 소량으로, 앞면브래킷의 뒤쪽밑바닥에 뚫려 있는 물빠지는 구멍을 통해서 배출된다.Water penetrating through the gap between the pinion and the bulkhead is discharged through the bottom drain hole. The remaining water is discharged in small amounts through the water draining holes in the rear bottom of the front bracket.
제 1 도 및 제 2 도는 본 고안에 의한 시동전동기의 방수장치의 한 실시예를 나타내는 단면도 및 정면도이고, 1~4, 6~17, 17는 상기 종래의 장치와 동일한 것이다. 20은 계철(2)에 부착된 앞면브래킷이고, 피니언(12)부의 아래쪽 개구부(20a)에 피니언(12)의 외경으로부터 근소한 간극을 두고 방수벽(21)이 설치되고, 그 저부에 배수구멍(21a)이 뚫려 있다. 또, 앞면브래킷(20)의 후방하부에 물빠지는구멍(21b)가 뚫려있다.1 and 2 are a cross-sectional view and a front view showing an embodiment of the waterproof device of the starting motor according to the present invention, 1 to 4, 6 to 17, 17 are the same as the conventional device. 20 is a front bracket attached to the yoke 2, and a watertight wall 21 is provided in the lower opening 20a of the pinion 12 with a slight gap from the outer diameter of the pinion 12, and a drainage hole at the bottom thereof. 21a) is open. In addition, a hole 21b for draining is formed in the rear lower portion of the front bracket 20.
앞면브래킷(20)의 개구부(20a)에 설치된 방수벽(21)에 의해 외부로부터의 물보라 등의 침입이 억제되고 있다. 그러나, 피니언(12)이 외경과는 간극이 있고, 또 피니언(2)의 이(爾)사이에는 골이 있어 완전무결하게는 방수될 수 없다. 이들의 간극을 통해서 새어 들어온 소량의 물은 배수구멍(21a)를 통해서 배출된다. 그리하여, 남은 물은 있다하더라도 앞면브래킷(20)의 후방하부에 이르러 물빠지는 구멍(20b)를 통해서 배출된다.The waterproof wall 21 provided in the opening part 20a of the front bracket 20 suppresses the intrusion of the spray from the outside. However, the pinion 12 has a gap with the outer diameter, and there is a valley between the teeth of the pinion 2, so that it cannot be completely waterproof. A small amount of water leaked through these gaps is discharged through the drain hole 21a. Thus, the remaining water is discharged through the water hole 20b which reaches the rear lower part of the front bracket 20 even if there is any.
이상과 같이, 본 고안에 의하면, 앞면브래킷의 피니언부에 대한 하방위치의 개구부에 피니언의 외경과 근소한 간극을 두고 방수벽을 설치하고, 이 방수벽의 저부에 배수구멍을 갖추고, 또, 앞면브래킷의 후방하부에 물빠지는 구멍을 설치하고 있으므로, 개구부로부터 앞면브래킷 내로의 물 침입이 방수벽에 의해 억제되고, 침입한 물은 배수구멍을 통해서 배출되며, 소량의 물이 남아 있다하더라도 물빠지는 구멍을 통해서 배출되고, 전동기의 동작불량을 일으키는 일은 없다.As described above, according to the present invention, a watertight wall is provided in an opening at a lower position with respect to the pinion portion of the front bracket with a slight gap between the outer diameter of the pinion, and a drain hole is provided at the bottom of the watertight wall. Since a water draining hole is provided in the rear lower part of the water inlet, water intrusion from the opening into the front bracket is suppressed by the waterproof wall, and the intruded water is discharged through the drainage hole, and even if a small amount of water remains, It is discharged through and does not cause a malfunction of the motor.
