1 : 전동기 3 : 동력전달기어1: electric motor 3: power transmission gear
4 : 감속기어 5 : 회전기어4: Reduction Gear 5: Rotating Gear
6 : 투입스프링6: closing spring
본 고안은 차단기 조작기구중 투입스프링을 인장(축세)시키기 위한 장치에 관한 것으로, 좀더 구체적으로는 투입스프링의 인장을 위한 전동기와 투입스프링 사이의 동력전달 구조를 개선하여 전동기의 동력이 투입스프링에 정확하고 안정되게 전달될 수 있도록 한 것이다.The present invention relates to a device for tensioning (increasing) the closing spring of the breaker operating mechanism, and more specifically, to improve the power transmission structure between the closing spring and the closing spring of the closing spring, the power of the motor is applied to the closing spring. It is to ensure accurate and stable delivery.
차단기의 조작기구는 제 1 도에 도시한 바와 같이 동력을 발생시키는 전동기(1), 전동기의 축(2)과 편심되게 설치된 회전아암(7), 회전아암에 결합되어 전동기의 회전운동을 직선 왕복운동으로 바꾸어 톱니바퀴에 전달하여 주는 링크(8), 링크(8)와 함께 연동하면서 라체트(10)를 물고 회전시키는 톱니비퀴(9), 라체트(10)와 함께 회전하면서 투입스프링(6)을 인장시키는 캠(11), 캠(11)의 회전을 정지시키기 위한 베어링(12), 캠(11)을 정지상태로 부터 해제시키는 누름버튼(13), 투입스프링(6)의 힘을 차단기 접점에 전달하는 레버(14)(15), 레버에 의해 승, 하강 운동을 하면서 차단기 접점(17)을 접속 또는 탈락시키는 절연플랜지(16)등으로 구성되어 있다.As shown in FIG. 1, the operation mechanism of the circuit breaker is coupled to the motor 1 for generating power, the rotation arm 7 eccentrically installed with the shaft 2 of the motor, and the rotation arm to linearly reciprocate the rotational motion of the motor. Coupling spring (9) to bite and rotate ratchet (10) while interlocking with link (8) and link (8), which are transferred to the gearwheel, and rotated together with the injection spring (6). ), The cam 11 for tensioning the bearing, the bearing 12 for stopping the rotation of the cam 11, the push button 13 for releasing the cam 11 from the stopped state, and the force of the closing spring 6 are interrupted. And an insulating flange 16 for connecting or disconnecting the breaker contact 17 while moving up and down by the lever 14 and 15 to be transmitted to the contact.
따라서 제 2a 도와 같은 상태에서 전동기(1)에 전원을 인가하면 전동기축(2)과 편심으로 위치된 회전아암(7)이 회전함과 동시에 링크(8)가 직선운동을 하게 되고 링크(8)의 직선운동에 의해 톱니바퀴(9)가 라체트(10)를 물면서 라체트(10)와 캠(11)이 회전하게 되며, 캠(11)의 회전에 따라 제 2b 도와 같이 투입스프링(6)은 인장된다.Therefore, when power is applied to the motor 1 in the same state as 2a, the rotary arm 7 which is located eccentrically with the motor shaft 2 rotates, and the link 8 moves linearly. The ratchet 10 and the cam 11 rotate while the gear 9 bites the ratchet 10 by the linear motion of the feeder. As shown in FIG. ) Is tensioned.
또 캠(11)이 회전하여 투입스프링(6)이 상사점까지 인장되며 베어링(12)에 의해 캠(11)의 회전이 정지되어 투입스프링(6)을 인장된 상태로 유지시키고, 이 상태에서 차단기의 투입을 위해 누름버튼(13)을 눌러주면 캠(11)이 베어링(12)과의 걸림상태에서 해제됨과 동시에 인장되어 있는 투입스프링(6)이 원상태로 수축되며, 그 힘이 레버(14)(15)를 통해 절연플랜지(16)에 전달되어 접점(17)이 투입된다.In addition, the cam 11 rotates and the feeding spring 6 is stretched to the top dead center, and the rotation of the cam 11 is stopped by the bearing 12 to keep the feeding spring 6 in a tensioned state. Pressing the pushbutton 13 for the input of the breaker releases the cam 11 from the locked state with the bearing 12 and at the same time, the tensioned closing spring 6 is retracted to its original state. It is transmitted to the insulating flange 16 through the (15) and the contact 17 is input.
그러나 상기한 종래의 장치는 전동기(1)의 회전력을 링크(8)의 직선운동으로 바꾸어 라체트(10)와 캠(11)을 회전시키는 구조이기 때문에 회전아암(7)의 편심회전에 따른 높은 하중에 의해 회전아암(7)부분의 마모손실이 크고, 특히 톱니바퀴(9)의 톱니부분이 라체트(10)와 맞물려 밀어올리는 충격마찰에 의해 캠(11)이 회전하는 구조이어서 맞물리는 부분의 마모가 증가됨은 물론 기계적 강도저하와 소음발생의 원인이 된다.However, the above-described conventional apparatus has a structure in which the ratchet 10 and the cam 11 are rotated by changing the rotational force of the electric motor 1 to the linear motion of the link 8 so that the high rotational force of the rotary arm 7 can be obtained. The wear loss of the rotary arm 7 is large due to the load, and in particular, the cam 11 is rotated by the impact friction in which the toothed portion of the gear 9 meshes with the ratchet 10 and is pushed up. Not only does the wear increase, but also the mechanical strength decreases and causes noise.
그리고 상기한 톱니바퀴(9)와 라체트(10)의 충격마찰은 차단기 본체에도 커다른 진동을 유발시켜 차단기의 내구성도 약해지는 문제가 있다.In addition, the impact friction of the cogwheel 9 and the ratchet 10 causes a large vibration in the circuit breaker body, and thus the durability of the circuit breaker is also weakened.
본 고안은 직선왕복운동을 하는 링크와 라체트 및 톱니바퀴에 의해 캠을 회전시키는 종래의 장치와는 달리 스피어 기어(Spur Gear)에 의해 캠을 회전시킬 수 있는 개선된 구조의 장치를 제공하기 위한 것인바, 이를 첨부된 도면 제 3 도에 의해 더욱 상세히 설명하면 다음과 같다.The present invention is to provide a device of an improved structure that can rotate the cam by a spur gear, unlike the conventional device that rotates the cam by the link and the ratchet and the cogwheel in a linear reciprocating motion It will be described in more detail by the accompanying drawings, Figure 3 as follows.
전동기(1)의 축(2)에 동력전달기어(3)를 고정함과 함께 이 동력전달기어(3)에 감속기어(4)를 맞물리고 감속기어(4)에 회전기어(5)를 맞물려 회전기어(5)의 회전에 의해 캠이 회전하면서 투입스프링(6)을 인장시킬 수 있도록한 것이다.While the power transmission gear 3 is fixed to the shaft 2 of the motor 1, the reduction gear 4 is engaged with the power transmission gear 3 and the rotation gear 5 is engaged with the reduction gear 4. The cam is rotated by the rotation of the rotary gear (5) to tension the closing spring (6).
이와 같이 구성된 본 고안의 작용효과를 설명한다.It describes the effect of the present invention configured as described above.
이와 같이 구성된 본 고안의 작용효과를 설명한다.It describes the effect of the present invention configured as described above.
먼저 제 3a 도와 같이 투입스프링(6)이 수축되어 있는 상태에서 전동기(1)에 전원을 인가하면 전동기축(2)에 고정된 동력전달기어(3)가 회전함과 동시에 동력전달기어(3)와 맞물린 감속기어(4)가 호전을 하게 되고 감속기어(4)의 회전력이 회전기어(5)에 전달되어 회전기어(5)가 회전하게 되며, 회전기어(5)가 회전하면 캠이 회전함과 동시에 투입스프링(6)이 인장된다.First, when power is applied to the motor 1 while the closing spring 6 is contracted as shown in FIG. 3a, the power transmission gear 3 fixed to the motor shaft 2 rotates and the power transmission gear 3 Gearbox is engaged with the gearbox 4 and the rotational force of the gearbox 4 is transmitted to the rotary gear 5 so that the rotary gear 5 rotates. When the rotary gear 5 rotates, the cam rotates. At the same time the closing spring (6) is tensioned.
또 투입스프링(6)이 상사점까지 인장되면 베어링에 의해 캠의 회전이 정지되어 투입스프링(6)은 인장된 상태로 유지되며, 이 상태에서 차단기의 투입을 위해 누름버튼을 누르면 걸림상태에 있던 캠이 걸림상태에서 해제됨과 동시에 투입스프링(6)이 원상태로 복원되면서 차단기 접점을 투입시키게 되는 것이다.In addition, when the closing spring 6 is tensioned to the top dead center, the rotation of the cam is stopped by the bearing, and the closing spring 6 remains in a tensioned state. In this state, when the push button is pressed for closing the breaker, As the cam is released from the locked state and the closing spring 6 is restored to its original state, the breaker contact is input.
이상에서와 같이 본 고안은 전동기의 동력을 3개의 스피어기어(동력전달기어, 감속기어, 회전기어)에 의해 캠에 전달시켜 투입스프링을 인장하는 구조이어서 동력전달 과정에서의 진동이나 소음이 거의 없고 관련부품의 마모손실이 적어진다.As described above, the present invention has a structure in which the power of the electric motor is transmitted to the cam by three spear gears (power transmission gear, reduction gear, and rotation gear) to tension the input spring so that there is little vibration or noise in the power transmission process. Less wear loss of related parts.
또 기어의 잇수비에 의해 정확한 동력의 전달이 가능해지며, 관련부품의 감소에 따라 조립성의 향상과 제조원가의 절감도 가능해진다.In addition, accurate gear transmission is possible by the number of teeth of the gear, and as the related parts are reduced, assembling performance and manufacturing cost can be reduced.
