Description

감속장치의 윤활유공급구조Lubricant Supply Structure of Reduction Gear

본 고안은 원동기의 동력을 감속하는 감속장치의 구조에 관한 것으로 더 상세하게는 감속장치의 윤활유 공급구조에 관한 것이다.The present invention relates to a structure of a speed reducer for reducing the power of a prime mover, and more particularly, to a lubricant supply structure of a speed reducer.

종래의 감속장치는 도1에 도시된바처럼 개방된 구조로서 베벨기어(11, 21)로서 원동기의 동력을 전달받는 입력축(1)과 입력된 동력을 감속하여 기관에 동력을 전달시키는 출력축(2)으로 이루어지는데 입력축(1)의 일측단부에 스프로켓휠(13)이 형성되어 체인(C)으로서 원동기로부터 동력을 전달받는다. 그리고 입력축(1)과 출력축(2)은 각각 판상체로 된 서포터(12, 22)에 베어링(B)으로 지지된다. 그런데 감속기는 기관의 내부에 깊숙히 존재하는 관계로 감속기의 베어링등에 윤활유공급이 원활하지 못하며, 또한 종래의 감속기는 상술한바와 같이 개방된 구조로 되어 있어 요란한 소음이 발생하고 종래의 감속기에서는 베벨기어에 윤활유공급이 원활하지 못하여 마모가 발생하므로 이에따라 소음이 발생되고 감속기 수명이 짧아지게 되는 것이다.Conventional deceleration device is an open structure as shown in Figure 1 as the bevel gears (11, 21) the input shaft (1) receiving the power of the prime mover and the output shaft for transmitting power to the engine by reducing the input power (2) Sprocket wheel 13 is formed at one end of the input shaft (1) to receive power from the prime mover as a chain (C). The input shaft 1 and the output shaft 2 are supported by bearings B, respectively, on the supporters 12 and 22 made of plate bodies. However, since the reducer is deep inside the engine, lubricating oil is not smoothly supplied to the bearings of the reducer, and the conventional reducer has an open structure as described above. Since the lubricant is not smoothly supplied and wear occurs, the noise is generated and the reducer life is shortened.

상기와 같은 종래의 감속장치의 문제점을 해결하기 위하여 본 고안이 창안되었는데, 본 고안의 목적은 감속장치에서 발생되는 소음을 줄이고 베벨기어의 마모를 저감하는데 그 특징이 있는 것으로, 본 고안의 목적을 달성하기 위한 본 고안에 따른 감속장치는 출력축과 입력축의 일측 자유단부에 형성된 베벨기어를 윤활유가 담겨있는 통상의 오일리테이너인 기어박스에 수납시키고, 이 오일리테이너인 기어박스를 밀봉하여 윤활유의 누설이 없도록 하므로서 베벨기어 및 축의 회동을 돕는 베어링에 윤활유를 상시 공급하도록 한 것이다.The present invention was devised to solve the problems of the conventional deceleration device as described above. The object of the present invention is to reduce the noise generated in the reduction device and to reduce the wear of the bevel gear. Reduction device according to the present invention for storing the bevel gear formed on one side of the free end of the output shaft and the input shaft in the gearbox of the ordinary oil retainer containing the lubricating oil, sealing the gearbox of the oil retainer to prevent leakage of the lubricating oil Lubricant is always supplied to the bearing which helps the bevel gear and the shaft rotate.

본 고안에 따른 감속장치는 도2 및 도3에 도시된바처럼 육면체로 밀폐된 기어박스(300)를 형성하고 기어박스(300)내에 베벨기어가 형성되는데 원동기로부터 동력을 전달받는 입력축(100)과 감속된 동력을 기관에 동력을 전달하는 출력축(200)이 기어박스(300)의 측면판(310,320)을 각각 베어링(B,도시생략)으로 결합하여 회동 가능하게 형성하며, 양축(100,200)은 서로 직각 방향으로 설치되며, 기어박스(300)내에는 윤활유(O)를 충진시킨다. 그리고 기어박스(300)내에서 입력축(100)과 출력축(200)에 각각 베벨기어(110,210)가 형성되는데, 입력축(100)의 자유단부는 대향되는 측면판(330)에 맞대어 베어링(B,도시생략)으로 회동 가능하게 고정된다.The reduction device according to the present invention forms a gear box 300 sealed with a hexahedron as shown in FIGS. 2 and 3 and a bevel gear is formed in the gear box 300. The input shaft 100 receives power from the prime mover. And output shafts 200 for transmitting power to the engine and the reduced power are formed to be rotatable by coupling the side plates 310 and 320 of the gearbox 300 to bearings (B, not shown), respectively. It is installed in the direction perpendicular to each other, the gearbox 300 is filled with lubricating oil (O). In addition, bevel gears 110 and 210 are formed in the input shaft 100 and the output shaft 200 in the gearbox 300, respectively. The free ends of the input shaft 100 are opposed to the side plates 330 facing the bearings B (not shown). Fixed) so that rotation is possible.

입력축(100)과 출력축(200)이 기어박스(300)내로 진입되는 각 측면판(310) 외측에는 기어박스(300)를 밀봉하여 윤활유의 누설을 막는 실링(S)이 각각 형성됨은 도2와 도3에 의해 알 수 있다. 그리고 기어박스(300)의 측면판(330)에 기어박스(300)내에 윤활유(O)를 주입하기 위한 오일주입구(331)와 기어박스(300) 내부를 들여다볼 수 있는 투시창(332)이 형성된다.Sealing (S) for sealing the gear box 300 to prevent the leakage of lubricating oil is formed on the outside of each side plate 310 into which the input shaft 100 and the output shaft 200 enters the gear box 300, respectively. This can be seen from FIG. In addition, an oil inlet 331 for injecting lubricating oil O into the gear box 300 and a see-through window 332 through which the inside of the gear box 300 is formed may be formed on the side plate 330 of the gear box 300. do.

상기 투시창(332)은 기어박스(300)내의 윤활유 양의 정도를 감시하기 위한 것이다.The see-through window 332 is for monitoring the amount of lubricating oil in the gearbox 300.

이와같은 구조로 되어 있는 본 고안의 감속장치는 베벨기어를 수납하는 기어박스(300)내에 윤활유(O)를 충진시키므로 윤활유(O)가 베벨기어(110, 210)뿐 아니라 입력축(100)과 출력축(200)의 회동을 지지하는 베어링(B)에 상시 윤활유(O)를 급유하므로 베벨기어 및 베어링에서 마찰 줄어들어 감속기어의 작동이 원활하게 되며, 투시창(332)로서 기어박스(300)내의 윤활유(O) 잔존유무를 확인할 수 있고, 기어박스(300)내에 윤활유(O)가 충분치 못하면 오일주입구(331)에 의하여 윤활유(O)를 주입하고 기어박스(300) 내측 공간이 크므로 한번의 윤활유(O) 주입으로 상당시간 윤활유 재 주입을 하지 않아도 되는 것이다.The deceleration device of the present invention having such a structure fills the lubricating oil (O) in the gearbox (300) for accommodating the bevel gear, so that the lubricating oil (O) is not only the bevel gear (110, 210) but also the input shaft (100) and the output shaft. Since lubricating oil (O) is always supplied to the bearing (B) supporting the rotation of the (200), the friction is reduced in the bevel gear and the bearing to facilitate the operation of the reduction gear, and the lubricating oil in the gearbox 300 as the see-through window 332 ( O) It can be confirmed whether there is remaining, and if the lubricant (O) is not enough in the gearbox 300, the lubricant (O) is injected by the oil inlet 331, and the inner space of the gearbox 300 is large, so that only one lubricant ( O) You do not need to refill the lubricant for a long time.

상기와 같은 구성 및 작용을 갖는 본 고안에 따른 구조에 의한 감속장치는 베벨기어 및 베어링에 충분한 윤활유를 공급하도록 되어 있기에 감속장치에서 발생되는 소음이 현저히 저감되고 마찰에 의한 마모가 저감되어 장치의 수명이 길어지고, 투시창으로 기어박스내의 윤활유 잔존상태를 감시할 수 있고 기어박스내에 한번의 윤활유 공급으로 오랫동안 윤활유 공급없이 감속장치를 사용할 수 있어 그만큼 편이하다 할 것이다.Reduction device according to the present invention having the configuration and action as described above is to supply sufficient lubricating oil to the bevel gear and bearing, so that the noise generated in the reduction device is significantly reduced and the wear caused by friction is reduced, the life of the device This longer, viewing window can monitor the lubrication oil remaining in the gearbox, and a single supply of lubricating oil in the gearbox allows the deceleration device to be used without lubricating oil for a long time.
