Description
본 고안은 등속조인트의 내륜 이탈방지구(A leave preventer for shaft washer of constant velocity joint)에 관한 것으로, 더욱 상세하게는 내륜의 이탈을 방지함과 더불어 중공부로의 그리스 유입을 방지하는 이탈방지구를 제공할 수 있도록 한 것이다.The present invention relates to an A leave preventer for shaft washer of constant velocity joint, and more particularly, a release prevention device for preventing grease from entering into the hollow part while preventing the departure of the inner ring. It is to be provided.
일반적으로, 등속조인트는 구동축과 수동축간의 동력전달에 있어서 회전속도의 변동이 없이 두축의 접점을 축의 교차각의 2 등분선상에 있게 하여 등속으로 동력을 전달되게 한 것으로, 이와 같은 등속조인트는 앞바퀴 굴림식의 구동과 뒤바퀴 굴림식의 독립현가방식 등 큰 각도로 동력을 전달하는 부분에 사용된다.In general, constant velocity joints transmit power at constant speed by keeping the two-axis contacts on the bisector of the intersection angle of the shaft without changing the rotational speed in the power transmission between the drive shaft and the manual shaft. It is used for the part that transmits power at a large angle, such as a rolling drive and a rear suspension independent suspension method.
그리고, 상기한 바와 같은 등속조인트는 버필드조인트와 중간축 및 더블 오프셋 조인트로 구성되어 있는 것으로, 슬라이드형인 더블 오프셋 조인트는 트랜스액슬의 디프 사이드 기어의 스플라인에 삽입되고, 고정형인 버필드 조인트는 휠 쪽의 휠 허브의 스플라인에 삽입되게 되어 있다.The constant velocity joint is composed of a burfield joint, an intermediate shaft, and a double offset joint. The slide type double offset joint is inserted into the spline of the deep side gear of the transaxle, and the fixed burfield joint is a wheel. It is inserted into the spline of the wheel hub on the side.
또한, 상기 중간축의 양단에 결합되는 버필드조인트와 더블 오프셋 조인트는 내면에 오목형태로 케이지에 지지되어 내륜에 구속되어 있는 볼이 안내되는 구면의 안내홈이 형성되어 있어 상기 볼을 매개로 미끄럼접촉하며 동력이 전달되게 되어 있다.In addition, the burfield joint and the double offset joint coupled to both ends of the intermediate shaft are formed in a concave shape on the inner surface of the spherical guide groove which guides the ball that is supported by the cage and is constrained to the inner ring is sliding contact through the ball And power is to be transmitted.
한편, 상기 볼이 구속되는 내륜은 도 1 에 도시된 바와 같이 그 외면이 볼록한 형태로 이루어져 볼(24)이 안착되는 6 개의 안내홈이 등간격으로 형성되어 중간축(20)에 스플라인 결합되고, 그 외측에는 내륜(21)의 이탈을 방지하기 위하여 스냅링(22)이 결합되며, 윤활을 위하여 공급된 그리스가 중간축(20)의 중공부로 유입되는 것을 차단하기 위하여 상기 중공부(20a)를 밀봉하는 플러그(23)가 구비되어 있다.Meanwhile, as shown in FIG. 1, the inner ring on which the ball is constrained has a convex shape on its outer surface, and six guide grooves on which the ball 24 is seated are formed at equal intervals to be splined to the intermediate shaft 20. A snap ring 22 is coupled to the outside to prevent the inner ring 21 from being separated, and the hollow part 20a is sealed to prevent the grease supplied for lubrication from flowing into the hollow part of the intermediate shaft 20. The plug 23 is provided.
그러나, 상기한 바와 같은 종래의 등속조인트의 내륜(21)이 중간축(20)에서 이탈되지 않게 하는 스냅링(22)과 중공부(20a)로의 그리스 유입을 방지하는 플러그(23)가 별도 구비되어야 하므로 제조원가가 상승되고, 조립공정이 복잡하여 생산성이 저하되며, 내륜(21)의 위치확보 및 고정성능의 확보가 곤란한 한편, 그리스의 밀봉이 곤란한 문제점이 있다.However, a snap ring 22 for preventing the inner ring 21 of the conventional constant velocity joint from being separated from the intermediate shaft 20 and a plug 23 for preventing grease from entering the hollow portion 20a should be separately provided. Therefore, the manufacturing cost is increased, the assembly process is complicated, the productivity is lowered, it is difficult to secure the position of the inner ring 21 and to secure the fixing performance, and difficult to seal the grease.
이에, 본 고안은 상술한 문제점을 해결하기 위하여 안출된 것으로, 등속조인트의 내륜이 축에서 이탈되는 것을 방지함과 더불어 중간축의 중공부로의 그리스 유입을 방지하는 이탈방지구를 제공할 수 있도록 함을 본 고안의 목적으로 한다.Accordingly, the present invention is devised to solve the above-described problems, to prevent the inner ring of the constant velocity joint from being separated from the shaft, and to provide a release prevention tool for preventing grease from entering the hollow portion of the intermediate shaft. It is for the purpose of the present invention.

상기 목적을 달성하기 위한 본 고안은 중간축에 내륜의 이탈이 방지함과 더불어 중공부에 나사 결합되어 상기 중공부를 밀봉하는 이탈방지구와, 상기 이탈방지구에 풀림방지수단을 구비한 것으로, 내륜의 이탈을 방지함과 더불어 중공부를 밀봉하고 풀림방지수단에 의하여 이탈방지구의 풀림도 방지한다.The present invention for achieving the above object is to be provided with a separation prevention means for sealing the hollow part by being screwed to the hollow portion and preventing the separation of the inner ring on the intermediate shaft, and the release prevention means to the release prevention means, In addition to preventing separation, the hollow part is sealed and the release prevention tool is also prevented from loosening by the release preventing means.
이하 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings.
도 2 는 본 고안의 분해 사시도이고, 도 3 는 본 고안에 따른 측단면도로서, 본 고안은 내륜(21)의 이탈을 방지함과 더불어 중공부(20a)를 밀봉할 수 있도록 한 이탈방지구(1)를 구비한 것으로, 중간축(20)에 결합된 내륜(21)의 이탈을 방지함과 더불어 중공부(20a)로의 그리스 유입을 방지하며, 상기 이탈방지구(1)에 풀림방지수단을 구비하여 지면으로부터 전달되는 진동등으로 인한 이탈방지구(1)의 풀림을 방지한다.Figure 2 is an exploded perspective view of the present invention, Figure 3 is a side cross-sectional view according to the present invention, the present invention is to prevent the departure of the inner ring 21 and the separation prevention to seal the hollow portion (20a) ( 1), and prevents the separation of the inner ring (21) coupled to the intermediate shaft 20, and prevents the grease flow into the hollow portion (20a), and the release preventing means (1) It is provided to prevent the loosening of the separation prevention (1) due to vibrations transmitted from the ground.
이상과 같은 풀림방지수단으로는 스프링와셔(2) 또는 웨이브 와셔 등을 사용함으로 그 목적을 달성할 수 있다.As the anti-loosening means as described above, the purpose can be achieved by using a spring washer (2) or wave washer.
이하 본 고안의 작용에 대하여 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.
상기한 바와 같은 본 고안을 구비한 등속조인트는 중간축(20)에 결합된 내륜(21)의 이탈이방지하는 이탈방지구(1)가 스프링와셔(2)와 같은 풀림방지수단에 의하여 중공부(20a)에 풀림이 방지되게 나사 결합되어 있으므로 중간축(20)에 결합되어 있는 내륜(21)이 지면으로 전달되는 진동 등에도 이탈되지 않고, 중공부(20a)로의 그리스 유입으로 인한 그리스의 부족현상이 방지된다.The constant velocity joint provided with the present invention as described above has a release part (1) preventing the separation of the inner ring (21) coupled to the intermediate shaft (20) by a loosening preventing means such as a spring washer (2). Since it is screwed to prevent loosening in the 20a, the inner ring 21 coupled to the intermediate shaft 20 is not detached from vibrations transmitted to the ground, and there is a lack of grease due to grease inflow into the hollow portion 20a. The phenomenon is prevented.
따라서, 본 고안은 트랜스미션에서 바퀴로 동력을 전달하는 등속조인트의 내륜의 이탈을 방지하는 이탈방지구가 중공부로의 그리스 유입을 방지하므로 구성을 단순화하여 생산원가를 절감하고, 생산공정을 단순화하여 생산성을 향상시킬 수 있도록 한 매우 유용한 것이다.Therefore, the present invention prevents the inflow of the inner ring of the constant velocity joint that transmits the power from the transmission to the grease to prevent the inflow of grease into the hollow part, thereby simplifying the construction, reducing the production cost, and simplifying the production process, thereby improving productivity. One very useful thing to help improve it.
