The guide rails 9 having the grooves 9a and 9a 'formed on both side walls 8 and 8' of the housing 3, and inserting four support rollers 14 on the outer edge thereof. 9 ') is attached to the upper and lower parts so as to sandwich the support 10 having a projection 10' formed between the upper and lower surfaces therebetween, and the upper portion of the upper support rail 9 slides on the upper support rail 9. 11) to attach the adjustment lever 13 on the upper side of the support plate 5 and the pinion 12 protruded, and to the inside of the support 10, a yoke 10 " (2) and the sliding element (2) is coupled to the groove (15 ') formed on one surface of the rotation shaft 15 by the key (24), the rotation shaft (15) is a side wall (8) (8 1 ) And spur gears (17) And a shaft 25 is formed on one side of the housing 3 to build up the spur gear 17 'to engage with the spur gear 17 and the worm gear 18 on the shaft 25. And engage with the worm gear 18 'coupled to the shaft 26 fixed to the support plate 4, and insert the helical gear 19' on one side thereof to the output shaft fixed to the support plate 5 at the bottom thereof. It is configured to mesh with the helical gear 19 coupled to (20).
이와 같이 구성된 본 고안의 작용 및 효과는 다음과 같다.The operation and effects of the present invention configured as described above are as follows.
입력축(6)에 전달된 회전력을 체인(23)을 통해 전동축(7)에 전달하고 계속해서 이 회전력은 몸체(3)에 설치된 원반 마찰차(1)를 회전시키며, 그러면 원반 마찰차(1)에 접촉된 접동자(2)가 회전하면서 키이(24)에 의해 삽착된 회전축(15)이 동시에 회전한다.The rotational force transmitted to the input shaft 6 is transmitted to the transmission shaft 7 via the chain 23, and this rotational force rotates the disk friction wheel 1 installed on the body 3, and then the disk friction wheel 1 The rotating shaft 15 inserted by the key 24 rotates at the same time as the slide 2 in contact with the) rotates.
그러면 일단에 삽착된 스퍼어기어(17)와 회전하면서 이와 맞물린 스피어기어(17')가 회전하고 이 스퍼어기어(17')와 축(25)에 의해 연결된 워엄기어(18)가 회전하면서 상부에 맞물린 위엄기어(18')를 회전시키고 이 워엄기어(18')와 축(26)으로 연결된 헬리컬 기어(19')가 회전하면서 그 하부에 맞물린 헬리컬 기어(19)를 회전시킴으로서 이 헬리컬 기어(19)가 관상된 출력축(20)이 회전하게 되어 입력축(6)의 동력이 출력축(20)에 전달되는 것이다.Then, the spear gear 17 ', which is engaged with the spur gear 17 inserted in one end, rotates and the worm gear 18 connected by the spur gear 17' and the shaft 25 rotates, and the upper part rotates. The helical gear (18 ') engaged with the helical gear (19') and the helical gear (19 ') connected to the worm gear (18') and the shaft (26) by rotating the helical gear (19). The output shaft 20, which is correlated with 19, is rotated so that the power of the input shaft 6 is transmitted to the output shaft 20.
본 고안은 동력 전달시 그 회견속도를 무단변속 시키고 또한 역회전 동작이 가능한 바, 이를 구체적으로 설명하면 다음과 같다.The present invention is capable of continuously changing the speed of the interview during power transmission and also capable of reverse rotation, which will be described in detail as follows.
먼저 일정한 회전력이 입력축(6)에 전달될때 출력축(20)의 회전력을 변화시키고자 할 경우에는 원반마찰차(1)에 접촉된 접동자(2)를 이동시키면 되는데, 원반마찰차(1)의 중심에서 멀어질수록 출력축(20)의 회전수가 많아지며 그러므로 지지판(5)의 상부에 결착된 조절레버(13)를 회전시키면 이와 연결된 피니언(12)이 회전하고 그러면 이와 맞물린 래크(11)가 평행이동하는바, 이것은 래크(11)가 지지대(10)에 결착되어 있고 이 지지대(10)는 상, 하부에 돌기(10')가 형성되어 가이드레일(9)(9')의 홈(9a)(9a')에서 좌, 우 이동되어 결국 상부 가이드레일(9)의 상면에서 슬라이드되는 래크(11)의 이동에 따라 지지대 (10)가 이동하게 된다.First, when a constant rotational force is transmitted to the input shaft 6, when the rotational force of the output shaft 20 is to be changed, the sliding member 2 in contact with the disk friction vehicle 1 may be moved. As the distance from the center increases, the number of rotations of the output shaft 20 increases. Therefore, when the adjustment lever 13 attached to the upper portion of the support plate 5 is rotated, the pinion 12 connected thereto rotates, and the rack 11 engaged therewith is parallel. This is because the rack 11 is fastened to the support 10, and the support 10 has protrusions 10 'formed at the upper and lower portions thereof so that the grooves 9a of the guide rails 9 and 9' are formed. The support 10 is moved in accordance with the movement of the rack 11 which is moved left and right at 9a 'and eventually slides on the upper surface of the upper guide rail 9.
그러면 이 지지대(10)의 전면에 요크(10")가 부착되어 있고 이 요크(10")에 지지되는 접동자(2)는 회전축(15)에 형성된 홈(15')에서 키이(24)에 의해 걸려 있어 지지대(10)의 이동에 따라 동시에 회전축(15)상을 이동하므로 개재된 접동자(2)가 이동할 수 있게 되어 원반마찰차(1)의 중심에서 이동되는 것이다.Then, the yoke 10 " is attached to the front of the support 10, and the slide 2 supported on the yoke 10 " is provided to the key 24 in the groove 15 'formed in the rotation shaft 15. It is caught by the movement of the support shaft 10 at the same time to move on the rotating shaft 15 so that the interposed sliding member (2) is able to move is to be moved from the center of the disk friction car (1).
이와 같이 접동자(2)가 원반마찰차(1)의 중심에서 가장자리로 이동할수록 회전수가 많아지므로 회전속도가 빨라져 결국 각 기어(17)(17')(18)(18')(19)(19')를 매개로 하여 출력축(20)에 보다 상승된 회전수가 건달되어 변속이 이루어지는 것이다.In this way, since the number of revolutions increases as the slider 2 moves from the center of the disc friction car 1 to the edge, the rotational speed is increased, resulting in the gears 17, 17 ', 18, 18' and 19 '( 19 ') through the output shaft 20 is passed through the shift is made to shift.
한편 출력축(20)의 회전방향을 바꾸고자 할 경우에는 예를들어 원반마찰차(1)의 중심에서 우측에 접면된 접동자(2)를 원반마찰차(1)의 중심을 지나 좌측으로 이동시키면 역회전이 되는바, 이것은 조절레버(13)를 원래의 회전방향과 반대방향으로 회전시키면 피니언(12)과 맞물린 래크(11)가 반대방향으로 이동되며 이에 따라 지지대(10)의 이동에 따른 요크(10")가 움직여 접동자(2)가 이동하는 것이다.On the other hand, in the case of changing the rotation direction of the output shaft 20, for example, moving the sliding member (2) folded on the right side from the center of the disk friction car (1) to the left through the center of the disk friction car (1) It is reverse rotation, which means that when the control lever 13 is rotated in the opposite direction to the original rotation direction, the rack 11 engaged with the pinion 12 is moved in the opposite direction, and thus the yoke according to the movement of the support 10 is moved. (10 ") moves, and the sliding part 2 moves.
그러면 역회전된 접동자(2)의 회전력이 회전축(15)을 회전시켜 각 기어들을 경유하여 출력축(20)에 전달, 역회전이 수행되는 것이다.Then, the rotational force of the reversely rotated sliding element 2 rotates the rotation shaft 15 to be transmitted to the output shaft 20 via each gear, and reverse rotation is performed.
위와 같이 본 고안은 조절레버의 회전에 따라 원반마찰차에 접촉된 마찰차를 이동시켜, 무단변속 및 역회전이 원활하게 수행되며 그 제작이 간편하고 더욱이 양 지지판에 의해 외력의 영향을 차단하고 원반마찰차가 몸체내에서 회동되므로 외부의 영향을 받지 않고 안정되게 작동되어 그 회전력을 마찰차에 전달, 출력축에 최종적으로 전달함으로서 소음이 적으면서도 충격에 강한 잇점이 있는 것이다.As described above, the present invention moves the friction wheel in contact with the disk friction car according to the rotation of the control lever, so that the stepless speed change and the reverse rotation are performed smoothly, and the production is simple, and furthermore, the influence of external force is blocked by both support plates and the disk Since the friction wheel is rotated in the body, it operates stably without being influenced by the outside, and transmits the rotational force to the friction wheel and finally transmits it to the output shaft.
