CONSTITUTION: An overrunning clutch(5) comprises an armature installed in a housing having an electronic switch, a spline arranged at an axis of the armature, and a pinion(6), the overrunning clutch(5) and the pinion(6) being coupled with each other by a cover(7), wherein a panel(71) to form the cover(7) is cut to have an appropriate diameter, and bent to form a roll shape, thus forming the cylindrical cover(7). At a state where the pinion(6) is pressedly inserted into the overrunning clutch(5) with the cover(7) penetrating the pinion(6), the overrunning clutch(5) is coupled thereto.

Description

시동전동기의 오버런닝 클러치 {Over running clutch of start motor}Over running clutch of start motor

본 발명은 자동차 등의 엔진 시동을 위하여 엔진의 링기어와 치합되면서 시동시키는 피니언을 설치하고 이 피니언의 과동작을 방지하기 위한 오버런닝 클러치를 설치한 시동 전동기에 있어서, 상기 오버런닝 클러치에 피니언을 커버로 고정되게 설치하고 상기 커버를 판재상태에서 롤상으로 형성하여 이를 피니언의 외경크기에 상관없이 설치할수 있도록 한 시동전동기의 오버런닝 클러치에 관한 것이다.The present invention provides a starter motor having a pinion which starts while being engaged with a ring gear of an engine for starting an engine of an automobile, and an overrunning clutch for preventing over pin operation of the pinion. The overrun clutch of the starter motor is fixedly installed by a cover and the cover is formed in a roll shape in a sheet state so that it can be installed regardless of the outer diameter of the pinion.

일반적으로 자동차 등의 엔진에는 엔진의 시동과 관성을 이용하기 위하여 링기어가 설치된 플라이 휠을 설치하고 있으며 이 플라이 휠은 시동전동기에 설치된 피니언으로 회전시켜 엔진을 시동시키도록 되어있고, 상기 시동전동기는 밧데리로부터의 전원을 인가 받아 작동되는 전자 스위치에 의해서 피니언이 상기 링기어와 치합되어 엔진을 시동시킨 다음, 오버런닝 클러치에 의하여 다시 원위치되는 작동을 하도록 되어있다.In general, engines such as automobiles are provided with a flywheel in which a ring gear is installed in order to use engine starting and inertia, and the flywheel is configured to start the engine by rotating with a pinion installed in the starting motor. The pinion is engaged with the ring gear to start the engine by an electronic switch which is operated by receiving power from the battery, and then is operated again by the overrunning clutch.

한편, 상기와 같이 작동되는 시동전동기에 있어서, 종래의 오버런닝 클러치는 도 1 및 도 2에서와 같이 전자스위치(2)가 설치되는 하우징(1)에 아마츄어(3)를 설치하고 이 아마츄어(3)의 축(4) 일방에는 스플라인을 형성하여 이에 피니언(6)이 설치되는 오버런닝 클러치(5)를 설치하되, 이 오버런닝 클러치(5)와 상기 피니언(6)을 외주에 상기 피니언의 치형 사이를 통과하는 절곡편(702)이 형성된 커버(701)로 결합되도록하여 구성되어 있었다.On the other hand, in the starting motor operated as described above, in the conventional overrunning clutch, the armature 3 is installed in the housing 1 in which the electronic switch 2 is installed, as shown in Figs. On one side of the shaft 4, a spline is formed and an overrunning clutch 5 to which the pinion 6 is installed is provided, and the overrunning clutch 5 and the pinion 6 are formed on the outer circumference thereof. The bent piece 702 passing therebetween was configured to be coupled to the formed cover 701.

그러나, 상기와 같은 종래의 것은 상기 오버런닝 클러치에 설치되는 커버에 피니언의 치형에 맞는 절곡편을 여러개 형성하면서 제조해야 하므로 이를 제조하기 위한 공정이 많이 들게 되어 생산성이 크게 저하되는 폐단이 있었고 또, 상기 피니언의 외경이 상기 커버의 절곡편 내주와 같거나 클 경우 상기 커버를 피니언을 관통시킬 수 없었기 때문에 상기 커버의 절곡편 내주는 상기 피니언의 외경보다 크게 형성해야 했으며, 상기 피니언의 외경을 확장시키는 경우에는 상기와 같이 피니언과 커버 및 오버런닝 클러치(5)를 결합하지 못하게 되고 이에 따라 상기 커버의 전체적인 크기와 부피가 커지게 되어 시동전동기 전체의 부피가 늘어나게 되는 등의 문제점이 있었다.However, the prior art as described above has to be manufactured while forming a plurality of bending pieces that fit the teeth of the pinion on the cover installed in the overrunning clutch, so that a lot of processes for manufacturing them take place, and the productivity is greatly reduced. Since the cover could not penetrate the pinion when the outer diameter of the pinion was equal to or greater than the inner circumference of the bent piece of the cover, the inner fold of the cover should be made larger than the outer diameter of the pinion, and the outer diameter of the pinion was expanded. In this case, the pinion and the cover and the overrunning clutch 5 cannot be coupled as described above, thereby increasing the overall size and volume of the cover, thereby increasing the volume of the entire starter motor.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 자동차 등의 엔진 시동을 위하여 엔진의 링기어와 치합되면서 시동시키는 피니언을 설치하고 이 피니언의 과동작을 방지하기 위한 오버런닝 클러치를 설치한 시동 전동기에 있어서, 상기 오버런닝 클러치에 피니언을 커버로 고정되게 설치하고 상기 커버를 판재상태에서 롤상으로 형성하여 이를 피니언의 외경크기에 상관없이 설치할수 있도록 한 시동전동기의 오버런닝 클러치와 그 조립방법을 제공하려는 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, and installs a pinion to be started while being engaged with a ring gear of an engine for starting an engine such as a car, and installs an overrunning clutch for preventing over pinion operation. In one starting motor, the overrunning clutch of the starter motor and its assembly are installed so that the pinion is fixed to the overrunning clutch with a cover, and the cover is formed in a roll shape in a plate state so that it can be installed regardless of the outer diameter of the pinion. It is intended to provide a method, which will be described in detail below with reference to the accompanying drawings and embodiments as follows.
