본 고안은 기어드 모터(Geared Motor) 감속기 윤활유의 모터측 유입방지장치에 관한 것으로서, 특히 가정이나 산업 설비의 동력원으로 이용되는 기계장치중에서 모터와 감속기가 일체형으로 구성된 동력발생 및 동력전달장치의 감속기 내부에 충진된 윤활유가 모터측으로 유입되는 것을 방지하기 위한 기어드 모터 감속기 윤활유의 모터측 유입방지장치에 관한것이다.The present invention relates to the inflow prevention device of the geared motor reducer lubricating oil. Especially, among the mechanical devices used as the power source of home or industrial equipment, the reducer of the power generating and power transmission device in which the motor and the reducer are integrated. The present invention relates to a motor-side inflow prevention device of a geared motor reducer lubricating oil for preventing the lubricant oil filled in the motor from flowing into the motor side.

종래에는 제1도에 도시한 바와같이 기어드 모터(Geared Motor)(21)가 모터(3)의 회전력을 감속기(1)에 전달하기 위해서 샤프트(5)를 사용하는데 모터의 샤프트와 감속기 기어샤프트가 감속기 내부에서 서로 연결되어 있다.Conventionally, as shown in FIG. 1, the geared motor 21 uses the shaft 5 to transmit the rotational force of the motor 3 to the reducer 1. They are connected to each other inside the reducer.

이때 모터 샤프트(5)와 감속기 기어샤프트는 오일 실(Oil Seal)(10)을 이용하여 감속기 내부의 윤활유가 모터(3) 측으로 유입되는 것을 방지하고 있다.At this time, the motor shaft 5 and the reducer gear shaft are prevented from entering the motor 3 side with lubricating oil inside the reducer using an oil seal 10.

그러나 오일 실(10)이 오랜 사용으로 마모되거나 열화에 의해 손상이 되면 오일 실의 실링능력이 저하되는데 이때 감속기 기어의 회전 작용에 의해서 감속기(1) 내부의 윤활유가 일정한 압력을 받아서 유동되다가 샤프트(5)와 오일 실의 틈으로 유출되어 모터(3) 내부로 유입된다.However, when the oil seal 10 is worn out or damaged by deterioration for a long time, the sealing capacity of the oil seal decreases. At this time, the lubricating oil inside the reducer 1 flows under a constant pressure due to the rotation of the reducer gear, and then the shaft ( 5) flows into the gap of the oil seal and flows into the motor 3.

따라서 감속기(l) 내부 윤활유가 모터(3) 내부로 유입되면 모터의 절연이 불량해지고, 이 때문에 모터가 소손되며, 또한 감속기 내부의 윤활유가 유출되어 레벨이 하락되면 기어의 작동이 원활하지 못하게 되고, 기어면에 마모 및 열화가 지속된다.Therefore, when the lubricant inside the reducer 1 flows into the motor 3, the insulation of the motor becomes poor, and thus the motor is burned out, and when the lubricant inside the reducer leaks and the level drops, the operation of the gear is not smooth. , Wear and deterioration on the gear surface.

본 고안은 상기와 같은 종래의 문제점을 해결하여 모터의 절연보호로 모터의 소손을 방지하고, 감속기의 파손을 방지할 수 있는 기어드 모터 감속기 윤활유의 모터측 유입방지장치를 제공함 그 목적이 있다.The object of the present invention is to provide a motor-side inflow preventing device of a geared motor reducer lubricating oil which can prevent the burnout of the motor by preventing the insulation of the motor to prevent damage to the motor, and to prevent breakage of the reducer.

상기의 목적을 달성하기 위하여 본 고안은 기어드 모터(Geared Motor)의 커플링 세트 케이스(Coupling Set Case) 하부에 내장되어 윤활유 출입을 위해 하부에 홈이 형성되는 케이스와, 상기 케이스에 오일의 부력에 의해 상하강되도록 부이(Buoy)가 내장되고, 상기 부이에 외해 상하강되도록 상기 케이스의 상부에 하부 금속판이 내장되며, 상기 하부 금속판의 상부에 설치되는 상부 금속판에는 부하가 연결되는 윤활유 유입감지부와, 상기 커플링 세트 케이스(Coupling Set Case)의 하면에 설치되는 드레인볼트로 구성되는 것을 특징으로 하는 기어드 모터 감속기 윤활유의 모터측 유입방지장치를 제공한다.In order to achieve the above object, the present invention is built in a coupling set case of a geared motor, and a case in which a groove is formed in the lower part for lubricating oil in and out of the buoyancy of oil in the case. Buoy is built up and down by the lower, the lower metal plate is built in the upper portion of the case so as to be lowered up and down outside the buoy, the upper metal plate installed on the upper portion of the lower metal plate and the lubricating oil inflow detection unit connected to the load and The present invention provides a motor-side inflow prevention device for a geared motor reducer lubricating oil, characterized in that it comprises a drain bolt installed on a lower surface of the coupling set case.

도면을 참조하여 본 고안을 상세히 설명한다.The present invention will be described in detail with reference to the drawings.

제2도는 본 고안에 따른 감속기 윤활유의 모터측 유입방지장치가 장착된 기어드 모터의 요부 단면도이다.2 is a sectional view of main parts of a geared motor equipped with a motor side inflow preventing device of a reducer lubricating oil according to the present invention.

윤활유 유입감지부(11)는 커플링 세트(Coupling Set) 케이스(22)의 내부 바닥 좌측홈에 설치되고, 커플링 세트(Coupling Set) 케이스(22)의 하면에는 드레인홀(Drain Hole)이 형성되어 개폐가 이루어지도록 드레인볼트(12)가 나합되어 있다.The lubricating oil inflow detection unit 11 is installed in the inner bottom left groove of the coupling set case 22, and a drain hole is formed in the lower surface of the coupling set case 22. The drain bolts 12 are screwed together to open and close.

그리고 윤활유 유입감지부(11)의 케이스(15)는 사각형상의 박스형으로 제작되어 좌측면을 제외한 나머지 삼면 하부에 윤활유의 출입이 자유롭게 이루어지도록 다수의 홈이 형성된다.In addition, the case 15 of the lubricating oil inflow detecting unit 11 is formed in a rectangular box shape, and a plurality of grooves are formed in the lower three surfaces except for the left side to freely enter and leave the lubricating oil.

또한 케이스(15)에는 윤활유의 부력에 의해 상하강되도록 구(球)형의 브이(Buoy)(13)가 내장되고, 브이의 좌우이동을 제한하고, 하부 금속판(19)의 쳐짐을 방지하기 위해 좌측에 금속판의 수직스토퍼(14)가 내장 설치된다.In addition, the case 15 has a spherical buoy 13 embedded therein so as to be moved up and down by buoyancy of the lubricating oil, to restrict the left and right movement of the v, and to prevent the lower metal plate 19 from sagging. On the left side, a vertical stopper 14 of a metal plate is built-in.

이때 케이스(15)의 좌측 상부에 내장되도록 설치되는 핀(16)에 좌측단이 회전 가능하도록 결합되는 하부 금속판(19)은 구(球)형의 브이(Buoy)(13)의 상하강 운동에 의해 상하강된다.At this time, the lower metal plate 19 coupled to the left end is rotatably coupled to the pin 16 installed to be embedded in the upper left of the case 15 to the vertical movement of the ball-shaped Buoy 13. By up and down.

여기서 하부 금속판(19)의 상부에는 상부 금속판(18)이 설치되고, 부이(13)에 의해 상하강되는 하부 금속판(19)의 우측단이 상부 금속판(18)의 하면에 접촉하게 된다.Here, the upper metal plate 18 is installed above the lower metal plate 19, and the right end of the lower metal plate 19, which is vertically lowered by the buoy 13, comes into contact with the lower surface of the upper metal plate 18.

한편 윤활유 유입감지부(11)에 외부 전원을 연결하여 윤활유 유입시 감지부(11)가 동작되면 통전이 되어 외부 부하(17)가 동작되도록 한다.Meanwhile, when an external power source is connected to the lubricating oil inflow detecting unit 11, when the sensing unit 11 is operated when the lubricating oil is inflowed, it is energized to operate the external load 17.

본 고안에 의한 기어드 모터 감속기 윤활유의 모터측 유입방지장치의 동작을 제2도를 참조하여 설명한다.The operation of the inflow preventing device of the motor side of the geared motor reducer lubricating oil according to the present invention will be described with reference to FIG.

오일 실(Oil Seal)(1O)의 열화, 마모, 손상으로 인한 실링(Sealing) 불량시 오일 실(Oil Seal)(10)과 샤프트(5) 사이에 틈이 발생하여 감속기(1) 내부의 윤활유가 샤프트(5)를 통해 모터(3)측으로 유입된다.In case of poor sealing due to deterioration, abrasion, or damage of the oil seal 10, a gap occurs between the oil seal 10 and the shaft 5, so that the lubricating oil inside the reducer 1 Flows into the motor (3) side through the shaft (5).

이때 유입된 감속기(1)의 오일이 커플링 세트 케이스(22)내부에 고이게 되면 윤활유 유입감지부(11) 내부의 부이(13)가 상부로 떠오르면서 하부 금속판(19)을 위로 밀어 올려서 상부 금속판(18)과 접촉이 된다.At this time, when the oil of the reducer 1 introduced therein accumulates in the coupling set case 22, the buoy 13 inside the lubricating oil inflow detection unit 11 floats upwards and pushes the lower metal plate 19 upward to raise the upper metal plate. In contact with (18).

여기서 하부 금속판(19)이 상부 금속판(18)에 접촉이 되면 통전이 되면서 외부의 설치된 부하(17)가 동작하게 되고, 이 시그널(Signal)을 확인 함으로써 감속기(1)의 윤활유 유출 상태를 외부에서 쉽게 확인할수 있다.In this case, when the lower metal plate 19 contacts the upper metal plate 18, while the electricity is supplied, the externally mounted load 17 is operated. By checking this signal, the state of lubricating oil of the speed reducer 1 is checked from the outside. Easy to see

한편 커플링 세트 케이스(22)의 내부 바닥에 일정한 양의 윤활유가 충진되면 드레인볼트(12)를 이용하여 유출시키면 부이(13)가 아래로 내려오게 되고, 하부 금속판(19)도 자중에 의해 아래로 내려오게 되며 수직스토퍼(14)에 의해 일정한 위치에서 멈추게 된다.On the other hand, when a certain amount of lubricating oil is filled in the inner bottom of the coupling set case 22, when the drain bolt 12 flows out, the buoy 13 is lowered, and the lower metal plate 19 is lowered by its own weight. It comes down to and stops at a certain position by the vertical stopper (14).

본 고안은 모터의 절연보호로 모터의 소손을 방지하고, 감속기의 파손을 방지할 수 있어 설비 보호와 정비비 절감 및 안정된 조업, 그리고 작업의 생산성을 향상시킬 수 있는 효과를 제공한다.The present invention prevents the motor from being burned out by the insulation protection of the motor and prevents the breaker from being damaged, thereby providing the effect of protecting the equipment, reducing maintenance costs, stable operation, and improving the productivity of the work.
