Description
본 고안은 웜과 웜기어를 통하여 연사기의 각 운동부에 동력을 전달하는 투포원 연사기용 기어박스에 관한 것이다.The present invention relates to a gearbox for a topo circle twister that transmits power to each moving part of the twister through a worm and a worm gear.
투포원 연사기용 기어박스에 대하여는 실용신안등록 제84551호 및 동제117783호등이 고안된 바 있으나 이들은 완벽한 누유방지는 기대할 수가 없고 또 웜축의 상부를 연결지지하는 볼트의 이완으로 부품의 손상 및 안전사고우려가 제기되고 있는 것이다.Utility model registration No. 84551 and No. 117783 have been devised for the two-wheeled twister gearbox, but they cannot be prevented from leaking completely. Also, the bolts supporting the upper part of the worm shaft are loosened to prevent damage and safety accidents. It is being raised.
즉 이들은 웜축의 회전시 기어박스 내에 공급된 윤활유가 웜축을 따라 배출되는 것을 방지하기 위하여 베어링 케이스 상부에 돌출부를 형성하고 웜축에는 별도제작되는 커버를 결합고정하여 베어링 케이스의 상부돌출부가 커버의 저부결합공에 결합되도록 한 것으로서, 커버로 인한 부품수의 증가로 제작경비가 추가소요되고 또 웜축과 커버 사이에 오링을 끼워준다 하더라도 장시간 사용시 오링의 마모로 누유가 발생되므로 완벽한 누유방지는 기대할 수가 없다.That is, they form a protrusion on the upper part of the bearing case to prevent the lubricant oil supplied into the gearbox from being discharged along the worm axis when the worm shaft rotates, and a cover manufactured separately is fixed to the worm shaft so that the upper protrusion of the bearing case is coupled to the bottom of the cover. As it is coupled to the ball, the manufacturing cost is additionally increased due to the increase in the number of parts due to the cover, and even if the O-ring is inserted between the worm shaft and the cover, oil leakage occurs due to the wear of the O-ring over a long period of time.
또한 웜축은 그 상단부에 볼트공을 형성하여 기어박스에 지지되는 상부베어링을 관통하도록 한 다음 와샤가 끼워진 볼트를 볼트공에 채결하여 지지고정토록 한 것으로서, 이는 웜축의 고속회전 및 고속회전시의 진동으로 볼트가 쉽게 이완될 우려가 있고 이완시에는 웜축이 자중에 의해 기어박스로부터 이탈하여 부품을 손상시키게 되고 또 안전사고를 야기시키게 되는 등의 문제점들이 있는 것이다.In addition, the worm shaft has a bolt hole formed at the upper end thereof to penetrate the upper bearing supported by the gear box, and then the bolt with the washer is attached to the bolt hole to fix the support. This is the vibration of the worm shaft at high speed and high speed. There is a concern that the bolt is easily loosened, and when the worm is loosened, the worm shaft is separated from the gearbox by its own weight, causing damage to the parts, and causing a safety accident.
이에 본 고안은 웜축을 통한 누유를 완벽하게 차단할 수가 있고 또 웜축의 상단부를 보다 견고히 연결지지할 수가 있는 투포원 연사기용 기어박스를 제공함에 그 목적이 있다.Therefore, the present invention has a purpose to provide a gearbox for a topo circle twister that can completely block leakage through the worm shaft and can more firmly support the upper end of the worm shaft.
상기한 목적달성을 위하여 본 고안은 웜축의 회전시 웜축으로부터 낙하하는윤활유가 웜축에 일체로 가공형성된 커버를 타고 흘러내리도록 하고 웜축 상단부에는 볼트를 일체로 가공형성하여 더블너트를 죄여줄 수 있도록 구성함을 특징으로 한다.In order to achieve the above object, the present invention is configured to allow the lubricating oil falling from the worm shaft to flow down through the cover formed integrally with the worm shaft while rotating the worm shaft, and to form a bolt integrally formed at the upper end of the worm shaft to tighten the double nut. It is characterized by.
