Description

스타터모터의 오버 런닝 클러치용 커버 조립구조 {A COVER STRUCTURE FOR OVERRUNNING CLUTCH OF STARTER MOTOR}Cover assembly for overrunning clutch of starter motor {A COVER STRUCTURE FOR OVERRUNNING CLUTCH OF STARTER MOTOR}

본 발명은 스타터모터의 오버 런닝 클러치용 커버 조립구조에 대한 것으로서, 더 상세하게는 오버 런닝 클러치의 조립 후 내부 윤활유가 누출되는 것을 방지하기 위하여 커버를 씌우되 사이징 효과를 증대시킬 수 있도록 한데 특징이 있는 것이다.The present invention relates to a cover assembly structure for the overrunning clutch of the starter motor, and more particularly, to cover the cover to prevent leakage of internal lubricant after assembly of the overrunning clutch, but to increase the sizing effect. It is.

일반적으로 자동차의 스타터 모터는 도 1에서 보는 바와 같이 회전력을 제공하기 위한 아마츄어 어셈브리(1)와, 그 회전축(2)의 선단에 마련된 피니언 어셈브리(3)와, 상기 피니언 어셈브리(3)의 단락을 조작하기 위한 레버(4)와, 상기 레버(4)를 작동시키는 마그네트 스위치(5)로 이루어지는 바, 상기 레버(4)의 작동으로 피니언 어셈브리(3)가 전진하면 그 선단의 피니언(31)이 차량의 링기어(도시하지 않았음)에 치합되어 동력을 전달할 수 있게 된다.Generally, a starter motor of an automobile includes an amateur assembly 1 for providing rotational force, a pinion assembly 3 provided at the tip of the rotation shaft 2, and the pinion assembly 3 as shown in FIG. 1. A lever 4 for operating a short circuit of the pin and a magnet switch 5 for operating the lever 4, and the pinion assembly 3 moves forward when the pinion assembly 3 advances by the operation of the lever 4; 31 is engaged with a ring gear (not shown) of the vehicle to transmit power.

이때, 상기한 피니언 어셈브리(3)의 스플라인(32)과 피니언(31)의 사이에는 롤러(33)가 개입되고, 롤러에는 윤활유가 공급되는 바, 이 윤활유가 누출되지 않도록 하기 위한 커버(6)가 씌워진다.At this time, the roller 33 is interposed between the spline 32 and the pinion 31 of the pinion assembly 3, the lubricant is supplied to the roller, the cover 6 for preventing the lubricant from leaking ) Is covered.

그리고 이와 같은 커버(6)는 바깥쪽으로 빠지지 않도록 하기 위해서 그 끝단을 스플라인부재(32)의 외경 끝단에 맞게 커얼링 하게 되는데, 이는 별도의 공정이 추가되므로 생산성이 떨어지는 단점이 있다.And the cover 6 is to be curled to fit the outer end of the spline member 32 in order not to fall outwards, which has a disadvantage in that productivity is reduced because an additional process is added.

그리고 또 한편으로는 커얼링을 하지 않고 치수관리로 사이징(Sizing)을 하여 끼우는 예가 있으나, 실제 밀폐효과가 미비하여 문제가 되었다.On the other hand, there is an example in which sizing is carried out by dimensional management without curling, but it is a problem due to a lack of actual sealing effect.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 발명의 주된 목적은 커버가 끼워지는 스플라인부재의 외주면에 환테홈을 형성하여 사이징 효과가 증대될 수 있도록 하는데 있으며, 더 나가서 윤활유의 밀폐효과를 상승시키고자 하는데 있는 것이다.Therefore, the present invention has been made in view of the conventional problems as described above to solve the complement, the main object of the invention is to form an annular groove on the outer circumferential surface of the spline member to which the cover is fitted to increase the sizing effect, It is to go further and increase the sealing effect of the lubricant.

이를 위한 특징적인 실시 수단은 회전력을 제공하기 위한 아마츄어 어셈브리와, 그 회전축의 선단에 연결된 피니언 어셈브리와, 상기 피니언 어셈브리의 단락을 조작하기 위한 레버와, 상기 레버를 작동시키는 마그네트 스위치로 이루어진 자동차용 스타터 모터에 있어서, 상기한 피니언 어셈브리의 스플라인부재의 외주면에 윤활유의 누출을 방지하기 위한 커버를 씌우되, 스플라인부재의 외주면에 2개 이상 복수의 환테요홈을 형성하여 사이징 효과를 향상시킬 수 있도록 하는데 있는 것이다.Characteristic implementation means for this consists of an amateur assembly for providing rotational force, a pinion assembly connected to the distal end of the axis of rotation, a lever for manipulating the short circuit of the pinion assembly, and a magnet switch for operating the lever. In the starter motor for a vehicle, a cover for preventing the leakage of lubricant is put on the outer circumferential surface of the spline member of the pinion assembly, and at least two annular grooves are formed on the outer circumferential surface of the spline member to improve the sizing effect. It is to make it possible.

이하 본 발명의 구성에 따른 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment according to the configuration of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 구성을 보인 오버 런닝 클러치부의 단면도이고, 도 3 및 도 4는 본 발명의 환테요홈의 예시도이다.Figure 2 is a cross-sectional view of the over running clutch portion showing the configuration of the present invention, Figure 3 and Figure 4 is an exemplary view of the ring groove of the present invention.

스타터 모터는 회전력을 제공하기 위한 아마츄어 어셈브리(1)와, 그 회전축(2)의 선단에 연결된 피니언 어셈브리(3)와, 상기 피니언 어셈브리(3)의 단락을 조작하기 위한 레버(4)와, 상기 레버(4)를 작동시키는 마그네트 스위치(5)로 이루어진다.The starter motor has an amateur assembly 1 for providing rotational force, a pinion assembly 3 connected to the tip of the rotation shaft 2, and a lever 4 for manipulating a short circuit of the pinion assembly 3. And a magnet switch 5 for operating the lever 4.

이때, 본 발명에서는 상기한 피니언 어셈브리(3)의 스플라인부재(32)의 외주면에 윤활유의 누출을 방지하기 위한 커버(6)를 씌우되, 스플라인부재(32)의 외주면에 2개 이상 복수의 환테요홈(32a)을 형성하여 사이징 효과를 향상시킬 수 있도록 한다.At this time, in the present invention, the cover 6 for preventing the leakage of lubricating oil is put on the outer circumferential surface of the spline member 32 of the pinion assembly 3, the two or more plural It is to form a ring groove (32a) to improve the sizing effect.

그리고 상기한 환테요홈(32a)은 반원형 단면을 갖도록 하되, 어느 한쪽을 경사면(32b)을 갖도록 하는 것이 좋다.And the annular groove 32a is to have a semi-circular cross-section, it is good to have one of the inclined surface (32b).

이와 같은 본 발명은 스플라인부재(32)의 내경 속으로 피니언 어셈브리(3)의 일단을 끼우고, 이들 사이에 롤러(33)가 개입되도록 한 상태에서 조립하되, 상기 롤러(33)가 빠지지 않도록 와셔(34)와, 커버(6)를 차례로 끼워 조립하면 된다.In the present invention as described above, one end of the pinion assembly 3 is inserted into the inner diameter of the spline member 32, and assembled in a state in which the roller 33 is interposed therebetween, so that the roller 33 does not fall out. What is necessary is just to insert the washer 34 and the cover 6 in turn.

커버(6)의 내경이 스플라인부재(32)의 외주면에 끼워지면 치수가 꼭 맞게 되어 있을 뿐만 아니라 2개의 환테요홈(32a)이 있으므로 사이징효과가 발생하여 쉽게 빠지지 않게 된다.When the inner diameter of the cover 6 is fitted to the outer circumferential surface of the spline member 32, not only the dimensions are fit but also there are two annular grooves 32a, so that the sizing effect occurs and does not fall easily.

특히 환테요홈(32a)은 그 형상이 일측편으로 경사면(32b)을 갖고 있기 때문에 사이징효과를 더 높일 수 있게 되는 것이다.In particular, since the annular groove 32a has the inclined surface 32b on one side, the sizing effect can be further increased.

위에서 상세히 설명한 바와 같은 본 발명은 스플라인부재(32)의 외경에 커버(6)를 씌워 윤활유의 누출을 예방할 수 있도록 하되, 2개의 환테요홈(32a)으로 쉽게 빠지지 않도록 하였기 때문에 종래의 커어링 공정이 삭제될 수 있고, 또 수명이 오래가는 등 여러 가지 장점을 가지는 것이다.The present invention as described in detail above to cover the outer diameter of the spline member 32 to prevent the leakage of lubricating oil, but not easy to fall into the two ring grooves (32a) of the conventional curling process It can be deleted and have a long lifespan.
