The first idle gear 14 is press-fitted and fixed, and the second idle gear 18 with the bearing 12 interposed therein is press-fitted on the output shaft 16 for receiving the power of the input shaft 10 in the same manner as the input shaft 10. It is fixed and the first and second idle gears 14 and 18 are geared to each other.
이과같이 구성된 종래의 아이들기어는, 입,출력축(10)(16)에 베어링(12)을 각각 개재시킨 상태에서 서호 치차맞춤되는 제1 및 제2아이들기어(14)(18)를 고정시켜 차량의 주행속도에 알맞도록 회전비를 변경하면서 회전된다.In the conventional idle gear configured as described above, the first and second idle gears 14 and 18 that are geared to each other are fixed while the bearing 12 is interposed between the input and output shafts 10 and 16, respectively. Rotating while changing the rotation ratio to suit the running speed of.
그러나, 상기와 같이 입,출력축에 베어링이 개재된 아이들기어를 고정시켰기 대문에 이로 인하여 서로 치차맞춤되는 아이들기어가 한쪽방향으로 치우쳐지므로 치(齒)와 치 사이의 간극(g) 즉, 백래쉬(backlash)가 커져 차량 주행 또는 공회전시 소음이 발생되어 주행시 정숙성이 저하되는 문제점이 있었다.However, since the idle gears with bearings are fixed to the input and output shafts as described above, the idle gears which are geared to each other are biased in one direction, so that the gap (g) between teeth and backlash ( There is a problem that the backlash is increased and noise is generated when driving or idling the vehicle, thereby decreasing quietness during driving.
본 고안은 상기와 같은 문제점을 해결하기 위한 것으로서, 본 고안은 입,출력축에 개재된 베어링 외측으로 삽입되어 동력절단시 제1 및 제2아이들기어의 치와 치 사이의 간극을 줄여 소음을 저감시키는 탄성부재로 구성된 것에 의해 달성된다.The present invention is to solve the above problems, the present invention is inserted into the bearing outside the input and output shaft to reduce the noise by reducing the gap between the teeth and teeth of the first and second idler gear during power cutting. It is achieved by being composed of an elastic member.
본 고안에 따른 탄성부재는 베이링 외측에 삽입되도록 소정의 탄성을 갖는 스프링 링으로 제작된 것에 의해 달성된다.The elastic member according to the present invention is achieved by being made of a spring ring having a predetermined elasticity to be inserted outside the bearing.

이하, 본 고안에 따른 아이들기어의 소음 저감장치에 대한 바람직한 일실시예를 첨부도면에 의거하여 상세하게 설명한다.Hereinafter, a preferred embodiment of the noise reduction device of the idle gear according to the present invention will be described in detail based on the accompanying drawings.
도2 및 도3은 본 고안에 따른 소음 저감장치를 나타낸 도면으로서, 입력축(10) 외주면에는 베어링(12)이 압입고정되며, 베어링(12) 외측에는 탄성부재가 삽입되고, 탄성부재 외측에는 변속기 또는 차동장치의 동력을 전달하기 위한 제1아이들기어(14)가 압입고정된다.2 and 3 is a view showing a noise reduction device according to the present invention, the bearing 12 is press-fit and fixed to the outer peripheral surface of the input shaft 10, the elastic member is inserted into the bearing 12 outside, the transmission outside the elastic member Alternatively, the first idle gear 14 for transmitting power of the differential device is press-fitted.
또한, 입력축(10)의 동력을 전달받는 출력축(16) 외주면에도 입력축(10)과 마찬가지로 탄성부재가 삽입된 베어링(12)과 제2아이들기어(18)가 각각 압입고정되며, 탄성부재는 소정의 탄성을 갖는 스프링 링(20)을 제작된다.In addition, similarly to the input shaft 10, the bearing 12 and the second idler gear 18 into which the elastic member is inserted are press-fitted to the outer circumferential surface of the output shaft 16 through which the power of the input shaft 10 is transmitted. The spring ring 20 having an elasticity is manufactured.
