1 : 변속기 하우징 2 : 오일가이드 통로1 Transmission housing 2 Oil guide passage
3 : 샤프트 4 : 오일통로3: shaft 4: oil passage
본 고안은 중장비용 변속기에 있어서 공회전하는 각 기어와 샤프트사이에 오일을 별도의 공급수단없이 공급될 수 있도록 한 변속기의 윤활장치에 관한 것이다.The present invention relates to a lubrication device of a transmission such that oil can be supplied without a separate supply means between each idle gear and shaft in a transmission for heavy equipment.
일반적으로 중장비의 변속기에 있어서 전, 후진을 결정하는 전, 후진기어 및 속도를 변속하는 각 변속기어는 샤프트의 회전에 관계없이 공회전을 하다가 싱크로 매쉬에 의해 그 회전이 선택되어 지는데 이때, 각 기어와 샤프트 사이에는 마찰이 발생하게 된다.In general, in the transmission of heavy equipment, each of the transmission gears that determine forward and backward and the gear shifting speed are selected by the synchro mesh while idling regardless of the rotation of the shaft. Friction occurs between them.
상기 마찰에 의해 베어링과 샤프트 및 각 기어가 마모되는 것을 방지하기 위하여 전, 후진기어 및 변속기어가 설치된 샤프트와 베어링에 오일을 공급하게 되는 것이다.In order to prevent wear of the bearing, the shaft, and each gear due to the friction, oil is supplied to the shaft and the bearing in which the forward, reverse and transmission gears are installed.
그런데, 종래에는 오일의 공급을 단순히 기어의 회전에 의하여 발생하는 오일의 비산으로 부분 윤활하거나 강제로 윤활오일을 공급하다보니 별도의 오일펌프가 필요하였다.However, in the related art, since the oil is partially lubricated or forcedly supplied with lubricating oil by scattering of oil generated by simply rotating the gear, an additional oil pump was required.
따라서, 본 고안은 이와같은 문제점을 제거하기 위하여 안출된 것으로서, 기어의 회전에 의하여 비산하는 오일을 오일가이드를 통해 샤트와 기어사이 및 베어링에 분리 공급함으로써 베어링, 기어 및 샤프트의 마모를 방지하고, 마찰열의 발생을 억제하기 위한 별도의 오일 펌프없이 윤활성을 증대시키는데 목적이 있다.Therefore, the present invention was devised to eliminate such a problem, and prevents wear of bearings, gears and shafts by separately supplying oil scattered by the rotation of the gears between the shaft and the gears and the bearings through oil guides, The purpose is to increase the lubricity without a separate oil pump to suppress the generation of frictional heat.
전술한 목적을 달성하기 위한 본 고안의 특징은, 중장비용 변속기에 있어서, 상기 변속기의 하우징(1)과 커버(2')에 오일가이드 통로(2)를 연통되게 형성하고, 전후진 기어(5)(6)및 변속기어(7)가 장착된 샤프트(3)에 오일통로(4)를 형성하며, 상기 샤프트(3)의 일단부에 상기 오일가이드 통로(2)를 통해 유입되는 오일이 베어링과 오일통로(4)로 공급되게 양분하는 스페이스(8)를 장착함을 특징으로 하는 중장비용 변속기의 윤활장치를 제공한다.Features of the present invention for achieving the above object, in the transmission for heavy equipment, the oil guide passage (2) is formed in communication with the housing (1) and cover (2 ') of the transmission, and the forward and backward gear (5) (6) and the oil passage (4) is formed in the shaft (3) on which the transmission gear (7) is mounted, and oil flowing through the oil guide passage (2) at one end of the shaft (3) is bearing. And a space (8) for dividing the oil to be supplied to the oil passage (4).
이하, 본 고안을 첨부도면에 따라 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안이 적용된 상태의 변속기 단면도이고 제2도는 본 고안의 요부를 나타낸 부분단면도로서, 도면부호중 1은 변속기하우징, 2는 오일가이드 통로, 2'는 커버, 3은 샤프트, 4는 오일통로, 8은 스페이스이다.1 is a cross-sectional view of a transmission in the state of the present invention is applied, and FIG. 2 is a partial cross-sectional view showing the main part of the present invention. Oil passage, 8 is space.
제1도와 제2도에 도시된 바와같이, 엔진의 동력을 변속시키는 변속기에 있어서, 변속기의 하우징(1)및 커버(2')에 각 기어의 회전에 의해 오일을 샤프트(3)의 중심축 및 베어링 측으로 유동될 수 있도록 오일가이드 통로(2)를 연통되게 형성하고, 상기 샤프트(3)에 오일양분용 스페이스를 장착하여 오일가이드 통로(2)로부터 유입된 오일이 샤프트(3)중심 및 베어링으로 유입되도록 오일통로(4)를 형성한다.As shown in FIG. 1 and FIG. 2, in a transmission for shifting the power of an engine, oil is applied to the housing 1 and the cover 2 'of the transmission by rotation of each gear to the central axis of the shaft 3. And forming an oil guide passage 2 so as to flow to the bearing side, and installing an oil nutrient space on the shaft 3 so that oil introduced from the oil guide passage 2 is in the center of the shaft 3 and the bearing. The oil passage (4) is formed to flow into.
이때, 오일통로(4)를 샤프트(3)와 전, 후진 기어(5)(6)및 변속기어(7)가 마찰되는 부분으로 오일이 공급되도록 연장하여 형성한다.At this time, the oil passage 4 is formed by extending the oil to be supplied to the portion in which the shaft 3 and the forward, reverse gears 5, 6 and the transmission gear 7 are rubbed.
상기와 같이 구성된 본 고안은 엔진이 가동되어 각 기어가 회전을 하게 되면 각 기어(5)(6)(7)의 회전력에 의해 오일이 비산되게 된다.According to the present invention configured as described above, when the engine is operated and each gear rotates, oil is scattered by the rotational force of each gear 5, 6, 7.
이때, 비산되는 오일이 하우징(1)미 커버(2')에 형성된 오일가이드통로(2)로 유입되어 샤프트(3)일단에 장착된 스페이스(8)에 의해 양분되어 베어링에 오일의 일부가 공급되고 오일가이드 통로(8)를 통해 유입된 오일의 일부는 샤프트(3)의 오일통로(4)로 유입되면 샤프트(3)의 원심력에 의해 오일이 샤프트(3)와 기어가 접촉하는 접동부위로 흘러들어 가게 된다.At this time, the scattered oil flows into the oil guide passage (2) formed in the housing (1) and the cover (2 ') and is bisected by the space (8) mounted at one end of the shaft (3) to supply a part of the oil to the bearing. And part of the oil introduced through the oil guide passage (8) enters the oil passage (4) of the shaft (3) to the sliding part where the oil is in contact with the shaft (3) by the centrifugal force of the shaft (3). It flows in.
따라서, 베어링 및 샤프트(3)와 각 기어(5)(6)(7)가 마찰에 의해 마모되는 것을 방지할 수 있게 되고, 마찰력이 미세하게 발생되므로 마찰열에 의한 오일의 온도상승됨을 방지할 수 있는 등의 효괴가 있는 것이다.Therefore, the bearing and shaft 3 and the respective gears 5, 6 and 7 can be prevented from being worn by friction, and since the friction force is generated finely, the temperature rise of the oil due to frictional heat can be prevented. There is an effect such as that.
