Abstract
본 고안은 입력축을 정방향 혹은 역방향으로 구동해도 출력축에 항상 일방향으로만 동력이 전달되도록 구성된 일방향동력전달장치에 관한 것으로, 입력축(115)에 기어(111,112) 2개를 일정간격으로 결합하고, 상기 기어(111,112) 중심부에 일방향클러치(113,114)를 각각 회전방향이 다르게 결합하여 정방향 회전동력 전달과 역방향 회전동력 전달을 담당하게 하는 입력회전동력전달부와, 상기 입력축과 평행한 출력축(145)에 폭이 입력축 기어(112)보다 2배 이상의 기어(141)를 결합하여 한편에는 입력축 기어(112)와 맞물리고, 입력축 기어(111)와 출력축 기어(141)가 안에서 원활히 회전할 수 있는 크기의 원통형내접기어(131)로 입력축 기어(111)와 출력축 기어(141)가 서로 맞물리지 않도록 간격을 두고 배치하여 입력축 기어(111)와 출력축 기어(141)를 휘 감듯 결합한다. 그래서, 입력축 기어(111)가 회전하면 원통형내접기어(131)가 회전하여 반대편 출력축 기어(141)를 입력축 기어(111) 회전방향과 같은 방향으로 회전시켜 출력축에 전달된다. 그리고, 상기한 입력축의 다른 방향의 기어(112)는 출력축 기어(141)에 바로 맞물려서 방향을 전환하여 출력축에 회전동력을 전달하게 되는데, 그러므로 출력축(145)은 항상 일정한 방향으로 회전한다. 특히 본 고안의 일방향동력전달장치는 구조가 간단하며, 정방향과 역방향간에 기어비를 같게할 수 있는 특징을 갖는다.The present invention relates to a one-way power transmission device configured to always transmit power in one direction to the output shaft even when the input shaft is driven in the forward or reverse direction. The two gears 111 and 112 are coupled to the input shaft 115 at regular intervals, and the gear (111, 112) Input rotational power transmission unit for the one-way clutch (113, 114) in the rotational direction is coupled to each other in the center to be responsible for forward and reverse rotational power transmission, and the output shaft 145 parallel to the input shaft width Cylindrical internal gear of a size that combines the gear 141 more than twice the input shaft gear 112 and meshes with the input shaft gear 112 on the other hand, and the input shaft gear 111 and the output shaft gear 141 can rotate smoothly therein. The input shaft gear 111 and the output shaft gear 141 are arranged at intervals such that the input shaft gear 111 and the output shaft gear 141 are not engaged with each other so as to enclose the input shaft gear 111 and the output shaft gear 141. Thus, when the input shaft gear 111 is rotated, the cylindrical internal gear 131 is rotated to rotate the opposite output shaft gear 141 in the same direction as the rotation direction of the input shaft gear 111 is transmitted to the output shaft. In addition, the gear 112 in the other direction of the input shaft is directly engaged with the output shaft gear 141 to change the direction to transmit rotational power to the output shaft. Therefore, the output shaft 145 always rotates in a constant direction. In particular, the one-way power transmission device of the present invention is simple in structure, and has the feature of equalizing the gear ratio between the forward direction and the reverse direction.

This can be useful for. For example, when a rotational power is obtained by a pinion gear in a rack gear that moves linearly, the rotational power is frequently changed in direction, and the rotational power that is frequently changed in direction is one-way power of the present invention. When combined with the pinion shaft on the input shaft of the transmission device, power is always rotated in one direction at the output shaft, which is useful for a device requiring power rotating in one direction.
이러한 일방향동력전달장치는 다양한 특징을 갖는 제품들이 널리 알려져 있는데, 보조기어를 사용한 일방향동력전달장치로 국외특허 EP0369925, US5435583 가 있으며, 국내특허 10-0291849, 10-0421238, 20-0339832 가 있다.Such one-way power transmission device is widely known products having a variety of features, as a one-way power transmission device using an auxiliary gear, there are foreign patent EP0369925, US5435583, there is a domestic patent 10-0291849, 10-0421238, 20-0339832.
그러나, 이들 발명들은 제작이 까다로운 베벨기어를 이용한다든지 외기어와 내기어 사이에 유성기어를 이용하다 보니 외기어와 내기어의 기어비가 달라 정방향과 역방향의 기어 변속비 달라지는 문제점등이 있다.However, these inventions have problems such as using a bevel gear that is difficult to manufacture or using planetary gears between the outer gear and the inner gear, so that the gear ratio of the outer gear and the inner gear is different so that the gear shift ratio in the forward and reverse directions is different.
본 고안은 앞서 설명한 종래기술의 문제점을 해결하기 위하여, 제작이 수월한 평기어를 사용하여 기어의 마찰을 최소화하며, 간단한 구조와 부품수 줄여 제작단가를 낮추고, 특히 정방향이나 역방향의 경로를 1:1의 기어비로 입력축과 출력축간에 강한동력을 전달하기에 무리가 없는 일방향동력전달장치.The present invention minimizes the friction of gears by using spur gears, which are easy to manufacture, to reduce the manufacturing cost by reducing the structure and the number of parts, and in particular, forward or reverse paths 1: 1. One-way power transmission device with good gear ratio to transfer strong power between input shaft and output shaft.
이를 위하여 본 고안에서는 제작이 수월하고 마찰이 적은 평기어 사용하였으며, 정방향이나 역방향에서도 입력과 출력간에 똑같은 1:1의 기어비로 강한회전동력을 전달하기에 무리가 없도록 구성되는데, 본 고안의 실시예를 첨부 도면을 참고하여 상세히 설명하면 다음과 같다.To this end, the present invention uses a spur gear that is easy to manufacture and has low friction, and is configured so that there is no difficulty in transmitting a strong rotational power with the same 1: 1 gear ratio between the input and the output in the forward and reverse directions. When described in detail with reference to the accompanying drawings as follows.
도 1은 본 고안의 일방향동력전달장치를 나타내는 조립사시도이며, 도 2는 입력축과 출력축을 기준으로 한 단면도이고, 도 3은 분해사시도이다.1 is an assembled perspective view showing a one-way power transmission device of the present invention, Figure 2 is a cross-sectional view based on the input shaft and the output shaft, Figure 3 is an exploded perspective view.
본 고안의 구성은 수시로 회전방향이 변환되는 입력축1(115)과 상기 입력축1에 입력회전동력전달기어1,2(111,112)들을 일정간격으로 결합하고, 상기 입력회전동력전달기어1,2(111,112)들 중심부에 일방향클러치1,2(113,114)들을 각각 회전방향이 다르게 결합하여 정방향 회전동력 전달과 역방향 회전동력 전달을 담당하게 하는 입력회전동력전달부와, 상기 입력축1과 평행한 출력축1(145)에 폭이 입력축1의 입력회전동력전달기어2(112)보다 2,3배인 회전동력반전용기어1(141)를 결합하여 한편에는 입력축1의 입력회전동력전달기어2(112)와 맞물리고, 입력축1의 입력회전동력전달기어1(111)와 출력축1의 회전동력반전용기어1(141)가 안에서 원활히 회전할 수 있는 크기의 회전동력전달용내접기어1(131)로 입력축1의 입력회전동력전달기어1(111)와 출력축1의 회전동력반전용기어1(141)가 서로 맞물리지 않도록 간격을 두고 배치하여 입력축1의 입력회전동력전달기어1(111)와 출력축1의 회전동력반전용기어1(141)를 휘감듯 결합한다. 그래서, 입력축1의 입력회전동력전달기어1(111)가 회전하면 회전동력전달용내접기어1(131)가 회전하여 반대편 출력축1의 회전동력반전용기어1(141)를 입력축1의 입력회전동력전달기어1(111) 회전방향과 같은 방향으로 회전시켜 출력축1에 전달된다. 그리고, 상기한 입력축1의 다른 방향의 입력회전동력전달기어2(112)는 출력축1의 회전동력반전용기어1(141)에 바로 맞물려서 방향을 전환하여 출력축1에 회전동력을 전달하게 구성되어져, 입력축1이 정방향과 역방향으로 방향이 수시로 변경되면서 회전하여도 입력축1에 결합된 입력회전동력전달기어1,2(111,112)와 일방향클러치1,2(113,114)의 결합 방향에 따라 방향이 결정되며 입력회전동력전달기어1(111)는 출력축1에 동력전달방향을 그대로 전달되고, 입력회전동력전달기어2(112)는 회전동력반전용기어1(141)과 맞물려 출력축1에 동력전달방향을 반전하여 전달하게 되어 결국 입력축1의 방향이 수시로 바뀌어도 출력축1은 항상 같은 방향을 유지할 수 있게 작용하게 되는 것이다.The structure of the present invention is coupled to the input shaft 1 (115) and the input rotational power transmission gears 1, 2 (111, 112) at regular intervals to the input shaft 1, the rotational direction is changed from time to time, the input rotational power transmission gears 1, 2 (111,112) One-way clutch 1, 2 (113, 114) in the center of the rotation direction is coupled to the input rotation power transmission unit for the transmission of the forward rotational power and the reverse rotational power, respectively, and the output shaft 1 parallel to the input shaft 1 (145) ) Is combined with the rotational power transmission gear 1 (141), which is 2,3 times larger than the input rotational power transmission gear 2 (112) of the input shaft 1, and is engaged with the input rotational power transmission gear 2 (112) of the input shaft 1 The input of the input shaft 1 into the internal power transmission gear 1 (131) of the size that the input rotational power transmission gear 1 (111) of the input shaft 1 and the rotational power transfer gear 1 (141) of the output shaft 1 can rotate smoothly therein. Rotational power transmission gear 1 (111) and output shaft 1 rotational power transfer machine 1, 141 is wrapped around the rotary power seemed half only one gear 141 of the output shaft 1 and input rotational power transmission gears 1 111 of the input shaft 1 and disposed at a distance from each other so that they do not catch engages. Therefore, when the input rotational power transmission gear 1 (111) of the input shaft 1 rotates, the internal power transmission gear 1 (131) rotates to rotate the rotational power reversing gear 1 (141) of the opposite output shaft 1 input rotational power of the input shaft 1 The transmission gear 1 111 is rotated in the same direction as the rotational direction and transmitted to the output shaft 1. Then, the input rotational power transmission gear 2 (112) in the other direction of the input shaft 1 is configured to transfer the rotational power to the output shaft 1 by directly engaging with the rotational power transfer gear 1 (141) of the output shaft 1, Even if the input shaft 1 is rotated while the direction is changed in the forward and reverse directions from time to time, the direction is determined according to the coupling direction of the input rotary power transmission gears 1, 2 (111, 112) and one-way clutch 1, 2 (113, 114) coupled to the input shaft 1. Rotational power transmission gear 1 (111) is transmitted to the power transmission direction as it is to the output shaft 1, input rotational power transmission gear 2 (112) meshes with the rotational power transmission gear 1 (141) to reverse the power transmission direction to the output shaft 1 As a result, even if the direction of the input shaft 1 changes from time to time, the output shaft 1 is always able to maintain the same direction.
도 4는 본 고안의 또다른 실시예를 나타내는 조립사시도이며, 도 5는 분해사시도로서, 입력축2(215)에 지름이 다른 입력회전동력전달기어3,4(211,212)들을 나란히 결합하고, 상기 입력회전동력전달기어3,4(211,212)들 중심부에 일방향클러치3,4(213,214)들을 각각 회전방향이 다르게 결합하여 정방향 회전동력 전달과 역방향 회전동력 전달을 담당하게 하는 입력회전동력전달부와, 상기 입력축2에 평행한 출력축2(225)에 지름이 다른 회전동력반전용기어2(221)와 출력회전동력전달기어(222)를 나란히 결합하여 입력축2(215)에 결합된 지름이 큰 입력회전동력전달기어3(211)와 출력축2(225)에 결합된 지름이 큰 회전동력반전용기어2(221)를 맞물리도록 하여 입력축2의 회전력을 출력축2에 반전시키며, 입력축2에 결합된 지름이 작은 입력회전동력전달기어4(212)와 출력축2에 결합된 지름이 작은 출력회전동력전달기어(222)는 지름이 작다보니 서로 맞물리지 않게 되며 회전동력전달용내접기어2(231)로 휘감아 결합하여 입력축2의 입력회전동력전달기어4(212)의 회전방향과 같은 방향으로 출력축2에 전달한다. 그래서, 상술한바와 같이 출력축2(225)은 항상 일정한 방향으로 회전하는 특징으로 구성된 입력축2가 수시로 방향이 변하여도 출력축2는 항상 일방향으로만 회전하는 작용을 하게 된다. 본 고안에 따른 일방향동력전달장치는 상기 회전동력전달용내접기어2(231) 대신에 벨트로 구성될 수 있다.Figure 4 is an assembled perspective view showing another embodiment of the present invention, Figure 5 is an exploded perspective view, the input shaft 2 (215) coupled to the input rotational power transmission gears 3, 4 (211, 212) of different diameters side by side, the input An input rotational power transmission unit which combines one-way clutches 3 and 4 (213 and 214) at the centers of the rotational power transmission gears 3 and 4 (211 and 212) so as to be in charge of forward and reverse rotational power transmission; Large diameter input rotational power coupled to input shaft 2 (215) by combining parallel output shaft 2 (225) with parallel output shaft 2 (225) and output rotational power transmission gear 222 and output rotational power transmission gear 222. The transmission shaft 3 (211) and the output shaft 2 coupled to the output shaft 2 (225) of the large rotational power transmission gear 2 (221) to engage the inverted rotation force of the input shaft 2 to the output shaft 2, the small diameter coupled to the input shaft 2 Input rotation power transmission gear 4 (212) and output shaft 2 The small output rotation power transmission gear 222 has a small diameter so that the output rotation power transmission gear 222 is not engaged with each other. The output rotation power transmission gear 222 is wound around the rotation power transmission internal gear 2 231 and coupled to the rotation direction of the input rotation power transmission gear 4 (212) of the input shaft 2. It transfers to output shaft 2 in the same direction. Thus, as described above, the output shaft 2 225 always rotates in one direction even if the input shaft 2 configured to rotate in a constant direction changes in direction at any time. One-way power transmission device according to the present invention may be composed of a belt in place of the rotational power transmission internal gear 2 (231).
이상에서 설명한 바와 같이 본 고안의 일방향동력전달장치는 적은 부품과 간단한 구조로 구현할 수 있으며 제작과 기어간 마찰이 적은 평기어를 사용하므로써, 생산원가를 절감과 품질향상을 기대 할 수 있다.
