본 고안은 연사기용 워엄기어통에 있어서 윤활유 유출방지구조에 관한 것이며, 좀더 상세하게는 통상의 워엄기어통 내실 일측 저부에 형성된 베어링집을 워엄기어가 간섭받지 않는 범위내에서 신장시키고 워엄기어와 치합된 워엄의 일측 하단면과 베어링집에 결합된 베어링의 상면에 밀착되게 윤활유 유출방지구를 형성하여 워엄축의 저부에 결합된 풀리에 벨트장력이 걸려도 워엄축의 흔들림이 최소화되도록 견고히 잡아주고 또, 워엄축의 흔들림에 의한 유격을 방지함으로서 주입된 윤활유가 새는 것을 방지토록 한 것에 관한 것이다.The present invention relates to a lubricating oil leakage prevention structure in a worm gear box for a twisting machine, and more specifically, a bearing house formed at one bottom of an inner chamber of an ordinary worm gear box is extended within a range where the worm gear does not interfere and is engaged with the worm gear. Lubricating oil leakage prevention port is formed to be in close contact with the lower surface of one side of the worm and the upper surface of the bearing coupled to the bearing housing so that the pulley coupled to the bottom of the worm shaft firmly holds the worm shaft to minimize shaking even when the belt tension is applied. The present invention relates to preventing leakage of injected lubricant by preventing play by

종래의 경우 도면 제2도에 도시된 바와같이, 워엄기어통(1a) 내식의 일측 상, 하부에 형성된 베어링집(2a)(3a)에 결합된 베어링(8a)(9a)에 지지되도록 워엄(4a)이 결합된 워엄축(5a)을 축설하여 워엄기어(6a)를 치합하고, 하부 베어링집(3a)에 결합된 베어링(9a) 밑면에 밀착되게 오일시일(10a)이 내삽된 커버(7a)를 결합한 구조로서, 워엄(4a)과 워엄기어(6a)의 치합 구동시 발생되는 마모 및 발열에 대한 냉각, 윤활작용을 하는 윤활유 주입량이 결정되는 하부 베어링집(3a)의 높이(h)가 워엄기어(6a)의 간섭때문에 상대적으로 낮게 형성되어 있는 관계로 윤활유를 교체, 주입하는 주기가 짧아지게 되고 하부 베어링집(3a)의 높이(h)보다 윤활유를 많이 주입하게 되면 주입된 윤활유가 하부 베어링집(3a)의 구멍(D)으로 바로 유입되어 베어링집(3a)의 내경과 베어링(9a)의 외경 끼워맞춤 공차에 의한 틈새 및 워엄축(5a)의 외경과 베어링(9a)의 내경 끼워맞춤 공차에 의한 틈새로 윤활유가 유출되고, 또 워엄기어(6a)가 회전하면서 원심력에 의해 기어에 묻어 올라오는 윤활유가 워엄(4a)과 치합시 구멍(D)으로 떨어져 끼워맞춤 공차에 의한 틈새로 유출되고, 상·하부 베어링(8a)(9a)에만 의존하여 축설된 워엄축(5a)은 지지력이 약한데 워엄축(5a)의 저부에 결합된 풀리(11a)에 엔드레스벨트(12a)가 걸려 회동하게 되면 엔드레스벨트(12a)의 장력에 의해 워엄축(5a)에 과부하가 걸려 흔들림이 발생하면서 커버(7)에 결합된 오일시일(10a)과 베어링(9a)의 내, 외경 틈새가 더욱 더 벌어져 윤활유가 유출되면서 풀리(11a)와 엔드레스벨트(12a)에 묻게 되어 엔드레스벨트(12a)에 접촉되어 회전하는 스핀들의 회전비가 일정하지 않아 보빈에 권취된 실을 꼬아주는 연사작업 불량이 발생되고 또 엔드레스벨트(12a)에 묻어 튀어오르는 윤활유가 보빈에 권취된 실이나 연사되는 실에 묻어 오염되는 관계로 품질저하의 요인이 되며 엔드레스벨트에 묻은 윤활유를 닦아내거나 세척하기 위해 연사기를 정지시켜 엔드레스벨트를 풀리와 스핀들로부터 벗겨내야 함으로 생산성 저하의 문제가 있었다.In the prior art, as shown in FIG. 2, the worm gear (1a) is supported on the bearing (8a) 9a coupled to the bearing housing (2a) (3a) formed on one side, the lower portion of the corrosion resistance (1a) Cover 7a in which oil seal 10a is inserted in close contact with bottom surface of bearing 9a coupled to lower bearing housing 3a by erecting worm shaft 5a coupled with 4a). ), The height (h) of the lower bearing housing (3a) is determined to determine the amount of lubricating oil to cool and lubricate the wear and heat generated during the driving operation of the worm (4a) and worm gear (6a) Since the lubrication gear 6a is formed relatively low due to the interference of the worm gear 6a, the cycle of replacing and injecting the lubricating oil becomes shorter, and when the lubricating oil is injected more than the height h of the lower bearing housing 3a, the injected lubricating oil is lowered. Directly flows into the hole D of the bearing housing 3a, the inner diameter of the bearing housing 3a and the outer diameter of the bearing 9a Lubricant flows out of the gap due to the fitting tolerance and the gap between the outer diameter of the worm shaft 5a and the inner diameter fitting tolerance of the bearing 9a, and the worm gear 6a is rotated and buried in the gear by centrifugal force. The lubricating oil falls into the gap due to the fitting tolerance when the lubricating oil falls into the hole (D) when engaged with the worm (4a), and the worm shaft (5a) built up depending only on the upper and lower bearings (8a) and (9a) has a weak bearing force. When the endless belt 12a is caught and rotated by the pulley 11a coupled to the bottom of the worm shaft 5a, the worm shaft 5a is overloaded and shakes due to the tension of the endless belt 12a. The gap between the inner and outer diameters of the oil seal 10a and the bearing 9a coupled to the gap increases and the lubricant is leaked to the pulley 11a and the endless belt 12a so as to contact and rotate the endless belt 12a. The rotation ratio of the spindle is not constant and twist the thread wound on the bobbin. The main cause of poor quality of twisting work and the contaminated lubricating oil buried in the endless belt (12a) is contaminated by the thread wound on the bobbin or the twisted thread, which is a factor of deterioration.Wipe or clean the lubricating oil on the endless belt. In order to stop the twister, the endless belt has to be peeled off from the pulley and the spindle, which leads to a problem of reduced productivity.

즉, 본원고안의 워엄기어통(1)는 워엄(4)과 워엄기어(6) 치합 구동시 발생되는 마모와 발열을 방지하기 위한 윤활유 주입량이 워엄기어(6)의 간섭을 받지 않도록 하부 베어링집(3)의 높이(h')보다 주입되는 윤활유가 넘지 않도록 워엄기어통(1)의 일측에 설치된 유량계(17)로서 비교, 판단하여 주입하게 되고 윤활유 교체시는 드레인밸브(16)를 열어서 신속, 용이하게 배출하게 되는 것이다.That is, the worm gear box 1 of the present application has a lower bearing collection so that the amount of lubricating oil injected to prevent wear and heat generated when the worm 4 and the worm gear 6 are driven together is not interfered with the worm gear 6. It is compared, judged and injected as the flow meter 17 installed on one side of the worm gear box 1 so that the lubricating oil injected from the height h 'of (3) is not exceeded. It is easy to discharge.

워엄기어통(1)의 하부 베어링집(3) 높이(h')만큼 윤활유를 주입한 다음 워엄(4)과 워엄기어(6)를 치합 구동하게되면 주입된 윤활유는 워엄기어(6)의 기어에 묻어 워엄(4)에 치합되면서 그 접촉면에 유막을 만들어 마찰을 줄임으로서 마모, 발열을 적게하고 기어에 묻은 일부 윤활유는 하부로 떨어져 모이게 되는데 이 윤활유가 떨어지는 과정에서 워엄(4)의 밑면과 윤활유 유출방지구(14) 상면이 밀착 밀폐되어 윤활유가 워엄축(5)에 스며들지 못하고 윤활유 유출방지구(14)가 베어링집(3) 상부 내연에 밀삽되고 또 0형 링(15)으로 밀폐되고 떨어지는 윤활유가 유출되지 못하게 하면서 워엄축(5)을 견고히 지지하여 워엄축(5)의 흔들림을 방지하여 1차적으로 윤활유가 새는 것을 방지하고, 윤활유 유출방지구(14)의 오일시일(13)과 커버(7)의 이중 오일시일(10)로 윤활유 유출을 최종적으로 방지하게 되는 것이다.If lubricating oil is injected as much as the height h 'of the lower bearing housing 3 of the worm gear cylinder 1, and then the worm 4 and the worm gear 6 are driven to drive, the injected lubricant is gear of the worm gear 6; When the lubrication is applied to the worm (4), it creates an oil film on the contact surface to reduce friction, thereby reducing wear and heat, and some of the lubricating oil on the gear drops to the bottom. The upper surface of the outflow opening 14 is tightly sealed so that the lubricating oil cannot penetrate the worm shaft 5, and the outflow opening of the lubricating oil 14 is pushed into the upper portion of the bearing housing 3, and is sealed with the zero ring 15.
