본 고안은 모터의 베이스 플레이트 후부에 스크류축 및 이에 연동되는 링크기구를 장착하여 손쉽게 벨트의 장력 및 원동축과 종동축의 축간거리를 조절할 수 있도록 고안된 벨트길이 조절장치에 관한 것이다.The present invention relates to a belt length adjusting device designed to easily adjust the tension of the belt and the distance between the axis of the driven shaft and the driven shaft by mounting a screw shaft and a link mechanism linked to the rear of the base plate of the motor.

잘 아는 바와같이, 원동축의 종동축의 회전으로 전달 시키는데 있어서는 두 축간거리가 가까우면 마찰차 또는 기어등에 의한 직접 접촉에 의해 전동할 수 있으나 그 거리가 멀면 직접 접촉에 의한 동력 전달이 불가능하므로 벨트를 사용하게 되는데, 벨트는 장기간 사용하면 늘어지고 마모되기 때문에 장력을 재조정하거나 새것으로 교환하여야만 정상적으로 동력을 전달할 수 있게 된다.As is well known, in the transmission of the driven shaft of the driving shaft, if the distance between two axes is close, it can be transmitted by direct contact by friction difference or gear, but if the distance is far, the belt cannot be transmitted by direct contact. Since the belt is stretched and worn out over a long period of time, it is necessary to readjust the tension or replace it with a new one to transfer power normally.

상기와 같은 원인으로 벨트의 장력을 재조정하거나 교환하는 경우 종래에는 모터를 베이스 플레이트에 고정시킨 볼트를 풀어 이동시키거나 혹은 호형의 장공이 마련된 모터 일측 브라켓의 볼트를 풀어 타측 고정부를 힌지로 회전이동시키면서 축간거리를 조정하는 등의 수단으로 행하여 왔기 때문에 소형모터를 사용하는 경우에는 별다른 문제점이 없었으나 중형 또는 대형 모터의 경우에는 중량이 크므로 많은 인원이 필요하고 여러가지 공구를 사용함으로써 번거로움과 많은 시간이 소비되어 작업성 및 생산성 저하의 원인이 되는 문제점을 내포하고 있었다.In the case of adjusting or replacing the tension of the belt due to the above reason, conventionally, by unscrewing and fixing the bolt fixed to the base plate of the motor or by unscrewing the bolt of one bracket of the motor provided with the arc-shaped hole, the other fixing part is rotated by the hinge Since it has been done by means of adjusting the distance between the shafts, there is no problem when using a small motor, but the weight of a medium or large motor is large, so a large number of personnel are required. Time was consumed and contained the problem of causing workability and productivity fall.

따라서 본 고안자는 상기와 같은 종래의 수단들이 비경제적이고 능률적이라는 것을 충분히 감안하여 모터의 베이스 플레이트 후부에 스크류축과 이에 연동되는 링크기구를 설치하여 스크류축의 일측에 장착된 핸들을 회전시킴으로써 손쉽게 벨트의 장력을 조절함은 물론 원동축과 피동축의 축간거리를 조절하여 벨트의 교환이 용이하도록 고안된 본 고안의 벨트 길이 조정장치를 안출하게 되었다.Therefore, the present inventors fully consider that such conventional means are uneconomical and efficient, and easily install the screw shaft and the link mechanism interlocked with the screw shaft at the rear of the base plate of the motor, thereby easily rotating the handle mounted on one side of the screw shaft. As well as controlling the distance between the axis of the driving shaft and the driven shaft, the belt length adjusting device of the present invention is designed to facilitate the exchange of the belt.

이하, 본 고안의 구체적인 내용을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the specific content of the present invention in detail as follows.

도시한 바와같이 모터(1)가 부착된 지지판(2)의 저부는 베이스 플레이트(3)에 핀(4)으로 고정하고 상부 후면의 중앙부에는 주링크용 브라켓(5)이 형성되어 베이스 플레이트(3)상에 공지와 같이 베어링 하우징(6), (6')에 의해 횡방향으로 설치된 스크류축(7)상의 이동 브라켓(8) 사이에 주링크(9)를 개재하여 핀(10), (10')으로 연결하되 이동브라켓(8)은 환봉인 상태에서 양측에만 나사부가 마련되며 스크류축(7)의 일측 선단에는 핸들(11)을 부착하는 한편, 상기 주링크용 브라켓(5)의 하부 지지판(2)의 양측에는 보조링크용 브라켓(12), (12')이 마련되어 이와 대응하는 위치의 베이스 플레이트(3) 내부에 횡방향으로 마련된 안내봉(13), (13')에 좌, 우 미끄럼 이동이 가능하도록 설치된 지지구(14), (14')와의 사이에 보조링크(15), (15')를 개재시킨 핀(16), (16')으로 연결하여서 구성한 것으로 미설명 부호 18은 구동 V-벨트이다.As shown in the figure, the bottom of the support plate 2 to which the motor 1 is attached is fixed to the base plate 3 with a pin 4, and a main link bracket 5 is formed at the center of the upper rear surface to form the base plate 3. Pin 10, 10 via a main link 9 between the movement brackets 8 on the screw shaft 7 provided laterally by the bearing housings 6, 6 'as shown in the figure. ') But the movable bracket (8) is provided with a screw only on both sides in the state of the round bar and attaching the handle (11) to one end of the screw shaft (7), while the lower support plate of the main link bracket (5) Brackets 12 and 12 'for the auxiliary link are provided on both sides of (2), and the left and right guide rods 13 and 13' are provided in the transverse direction inside the base plate 3 at the corresponding position. By connecting the pins 16 and 16 'with the auxiliary links 15 and 15' between the supporters 14 and 14 'installed to allow the sliding movement. That generated by reference numeral 18 is a driving V- belt.

이와 같이 구성된 본 고안의 작용 효과를 제3도 (a), (b)를 보면서 설명하면 다음과 같다.Referring to Figure 3 (a), (b) the effect of the present invention configured as described above is as follows.

벨트(18)를 장기간 사용한 후 벨트(18)의 장력을 재조정하고자 할때에는 스크류축(17)의 일측에 부착된 핸들(11)을 역회전 시키면 스크류축(7)상에서 나사이동하는 이동브라켓(8)은 좌측으로 이동하게 되고 이와 연결된 주링크(9)가 기울어 지면서 지지판(2)이 우측으로 기울어져 축간거리가 멀어지게 됨으로써 벨트(18)의 장력을 조절할 수 있게 되는 것이며 반대로 벨트(18)의 교환시 즉, 양축간거리를 줄이고자 할때는 상기의 역순으로 핸들(11)을 정회전시키면 이동브라켓(8)이 우측으로 나사이동하면서 주링크(9)를 세우게 됨으로써 지지판(2) 또한 세워져 축간 거리가 줄어들게 되면 이때 벨트(18)를 새것으로 바꿔 끼운후 장력 조절시처럼 핸들(18)을 역회전 시키면서 조절하게 되는 것이다.In order to readjust the tension of the belt 18 after the belt 18 is used for a long time, when the handle 11 attached to one side of the screw shaft 17 is rotated in reverse, the movable bracket 8 which moves the screw on the screw shaft 7 is rotated. ) Is moved to the left side and the main link (9) connected thereto is inclined so that the support plate (2) is inclined to the right side so that the distance between the shafts can be farther away and the tension of the belt (18) can be adjusted. When replacing, that is, to reduce the distance between the two shafts, if the handle 11 is rotated forward in the reverse order as described above, the support bracket 2 is also erected because the support bracket 2 is erected while the movable bracket 8 is screwed to the right. When it is reduced, the belt 18 is replaced with a new one, and then it is adjusted while rotating the handle 18 in the same way as when the tension is adjusted.

여기서 지지판(2)의 좌, 우 양측으로 보조링크(15)를 설치한 것은 모터(1)의 작동시 지지판(2)의 떨림을 방지하기 위한 것으로서 주링크(9)와 같이 동작된다.The auxiliary link 15 is provided on both the left and right sides of the support plate 2 to prevent shaking of the support plate 2 during the operation of the motor 1 and is operated like the main link 9.

이상에서와 같이 본 고안에 의하면 종래에 비하여 볼트의 풀고 조임이 없이 손쉽게 핸들을 정, 역회전 시켜 벨트의 장력 및 축간거리를 조절함으로서 작업자에게 편리함을 제공하여 생산성 및 작업성 향상에 기여할 수 있는 실용적인 고안이라 하겠다.As described above, according to the present invention, the handle can be easily rotated forward and backward without loosening and tightening the bolt, thereby adjusting the belt tension and the distance between the shafts and providing convenience to the worker, thereby improving productivity and workability. It would be a devise.
