5 : 베어링 6 : 0링5: bearing 6: 0 ring

본 고안은 차량변속기의 기어윤활구조에 관한 것으로, 특히 윤활유가 베어링에 존재하게 되어 구조를 단순화시키고. 윤활작용을 향상시키도록 된 차량 변속기의 기어윤활구조에 관한 것이다.The present invention relates to a gear lubrication structure of a vehicle transmission, in particular lubricating oil is present in the bearing to simplify the structure. The present invention relates to a gear lubrication structure of a vehicle transmission adapted to improve lubrication.

일반적으로, 차량변속기는 기어의 치형과 맞물려 엔진으로부터 얻어진 동력을 감속 또는 가속시키어 차륜으로 전달함에 따라 각각의 기어에 마찰 및 마모가 발생하고, 이를 방지하기 위해 변속기내애 내장된 디퍼렌셜 파이널 드리븐기어(DIFFERENTTAL FINAL DRIVEN GEAR)로서 하부에 담겨진 오일 을 걷어올려 비산시켜 각기어의 마모와 마찰열을 감소시키게 되는데, 종래에는 제3도에 도시된 바와 같 이 주축(101)과 한쪽측면에 오일유입흠(106)을 갖춘 기어(102)사이에 마찰저항을 줄이기 위한 배어링 (105)이 삽입되고, 상기 기어(102)의 양측면에는 회전에 의한 기어(102)와, 상기 기어(102)의 오일 유입흠(106)으로 유입된 윤활유의 유출을 방지하기 위해 와셔(103)와 스냅링(104)이 체결되게 된다.In general, a vehicle transmission meshes with the teeth of a gear to reduce or accelerate the power obtained from the engine and transmits it to the wheels, thereby causing friction and wear to each gear. To prevent this, the differential final driven gear (DIFFERENTTAL) built into the transmission is prevented. FINAL DRIVEN GEAR) by lifting and scattering the oil contained in the lower portion to reduce the wear and frictional heat of each gear, conventionally as shown in Figure 3 oil inlet flaw 106 on the main shaft 101 and one side A bearing 105 for reducing frictional resistance is inserted between the gears 102 provided with the gears 102, and the gears 102 are rotated on both sides of the gears 102 and oil inflow flaws 106 of the gears 102. The washer 103 and the snap ring 104 are fastened to prevent the outflow of the lubricating oil introduced into the).

따라서, 엔진으로부터 동력을 전달받아 고속으로 회전되게 되는 기어(102)와 주축(101)의 결합부위에 는 디퍼렌션 파이널 드리븐기어에 의해 비산되어 각 기어(102)의 오일유입흠(106)으로 유입되는 윤활유가 공급되어 마모와 마찰열을 감소시키게 된다Therefore, the gear 102 and the main shaft 101 which are rotated at high speed by receiving power from the engine are scattered by the differential final driven gear and flow into the oil inflow flaw 106 of each gear 102. Lubricant is supplied to reduce wear and frictional heat.

그러나 이와같이 변속기내의 디퍼렌셜 파이널 드리븐기어에 의해 비산되는 윤활유가 기어(102)의 측면에 부딪쳐 이에 형성된 오일유입흠(106)으로 흘러들어가게 되면, 상기 디퍼렌셜 파이널 드리븐기어에 의해 비산되는 윤활유의 양이 충분치 못할 경우에는, 상기 오일유입흠(106)으로 유입되는 윤활유양이 적어 윤활작용이 충분히 되지 않게 되므로 결합부위에서 마모와 마찰열을 심하게 발생시키게 되는 등의 문제가 있었다.However, if the lubricating oil splashed by the differential final driven gear in the transmission hits the side of the gear 102 and flows into the oil inflow flaw 106 formed therein, the amount of the lubricating oil scattered by the differential final driven gear may not be sufficient. In this case, since the amount of lubricating oil flowing into the oil inflow flaw 106 is small and the lubrication action is not sufficient, there is a problem such that severe wear and frictional heat are generated at the coupling portion.

이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 주축과 기어사이에 삽입된 베어링에 윤활유를 내재시켜 변속기내의 윤활유양에 상관없이 항상 윤활작용이 되도록 된 차량변속기의 기어 윤활구조를 제공함에 그 목적이 있다.In order to solve the above problems, the present invention provides a gear lubrication structure of a vehicle transmission in which a lubricant inserted in a bearing inserted between a main shaft and a gear is always lubricated regardless of the amount of lubricating oil in the transmission. Has its purpose.

상기와 같은 목적을 달성하기 위한 본 고안은 주축과 기어.사이에는 윤활유를 내재시키고 베어링과 상기 베어링의 상측면 끝부위에는 0링이 삽입되고, 상기 기어(2)의 양측면에는 와셔(3)와 스냅링(4)이 체결되는 구조로 되어 있다.The present invention for achieving the above object is a lubricating oil between the main shaft and the gear. The zero ring is inserted into the bearing and the upper end of the bearing, and the washer (3) and both sides of the gear (2) The snap ring 4 is fastened.

이하 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 기어윤활구조를 도시한 것인 바, 주축(1)과 기어(2)사이에 윤활유를 내재시킨 베어링(5)과 상기 베어링의 양측면 끝부위에 마찰열에 의해 묽어진 윤활유의 유출을 방지하도록 0링 (6)이 삽입되고, 상기 기어(2)의 양측면에는 고속회전으로 인한 기어(2)의 이탈을 방지하기 위해 와셔 (3)와 스냅링(4)이 체결되게 된다.1 shows a gear lubrication structure according to the present invention, a bearing 5 having a lubricant embedded between the spindle 1 and a gear 2 and a lubricant thinned by frictional heat at both end portions of the bearings. The 0 ring 6 is inserted to prevent leakage of the washer, and both sides of the gear 2 are fastened to the washer 3 and the snap ring 4 to prevent the gear 2 from being separated due to the high speed rotation.

따라서 엔진으로부터 동력을 전달받아 고속으로 회전되게 되는 각기어(2)와 주축(1)의 결합부위에서 발생되는 마모와 마찰열이 베어링(5)에 내장된 윤활유에 의해 흡수되게 된다.Therefore, abrasion and frictional heat generated at the coupling portion of the angular gear 2 and the main shaft 1 that are rotated at high speed by receiving power from the engine are absorbed by the lubricating oil built into the bearing 5.

이상 설명한 바와 같이 본 고안에 의하면, 베어링에 윤활유가 내장되어 고속회전으로 인한 기어와 주축의 결합부위에서 발생되는 마모와 마찰열이 변속기내의 윤활유양에 상관없이 항상 흡수되고, 상기 기어에는 별도의 윤활유공급을 위한 장치가 필요없게 되어 구조가 간단하고 작업공정이 감소되는 효과가 있다.As described above, according to the present invention, the lubricating oil is embedded in the bearing so that the wear and frictional heat generated at the coupling portion between the gear and the main shaft due to the high speed rotation are always absorbed regardless of the amount of lubricating oil in the transmission. There is no need for a device for the structure is simple and has the effect of reducing the work process.
