본 고안은 동력경운기의 로터리 변속기어장치에 관한 것으로, 특히 간단한 구조로 로터리축을 정. 역회전 시킬수 있도록 된 동력경운기의 로터리 변속기어장치에 관한 것이다.The present invention relates to a rotary transmission gear device of a power cultivator, and in particular, defines a rotary shaft with a simple structure. The present invention relates to a rotary transmission gear device of a power tiller capable of rotating in reverse.

일반적으로 동력경운기로 부터 동력을 인출해서 각종 작업기구돌을 구동시키도록 된 동력인출축(PTO)은 한쪽 방향으로만 회전하도록 되어 있어서, 이 동력인출축에 연결되어 구동되는 작업기구 역시 한쪽방향으로만 회전구동시킬 수 밖에 없었다.In general, the power take-off shaft (PTO), which draws power from the power cultivator and drives various work tool stones, rotates in only one direction, so that the work tool connected to the power take-off shaft is also driven in one direction. Only rotation was forced to drive.

그런데 동력인출축에 연결해서 작업하고자 할때는 정. 역회전시켜야 할필요가 있을 때도 있게 되는바, 예컨대 작업기구로서 로타리를 장착하는 경우에는 땅속깊이 묻힌 초근등을 절단하거나 각종 배수로잡업 또는 복토,배토작업을 하기 위해 로타리를 교대로 정. 역회전시킬 필요가 있게 된다.But when I want to work with the power take-off shaft, There may be times when it is necessary to reverse the rotation. For example, if a rotary is used as a work tool, the rotary may be rotated alternately to cut the deep roots buried deep in the ground, or to carry out various drainage jobs, covering soil, and covering work. It will be necessary to reverse.

이와 같은 경우를 만족시키기 위해 본 출원인은 기히 실용신안등록출원 제 89-15285호로, 동력인출축에 트랜스밋션구조가 고정설치되어 동력인출축을 정회전 또는 역회전시켜주기도 하고 변속시킬 수도 있도록 된 동력경운기의 트랜스밋션구조물 제안한바 있으나, 이는 부품의 갯수가 많이 소요되고 구조가 복잡할 뿐만 아니라 동력인출에 필요한 트랜스밋션이 항상 갖추어져야 하기 때문에 무게가 많이 나가는 등의 결점이 있었다.In order to satisfy such a case, the present applicant is a utility model registration application No. 89-15285, which has a transmission structure fixedly installed on a power take-off shaft, which allows the power take-off shaft to rotate forward or reverse, or to shift. Transmission structure has been proposed, but it has a drawback such as a large number of parts, a complicated structure, and a heavy weight because the transmission required for power take-off must always be equipped.

또한 이러한 동력인출용 트랜스밋션구조 이외에도 로터리자체에 로터리 변속기어를 일체로 설치해서 동력인출력으로 부터 체인을 동해 전달된 동력이 변속되고 정역 회전시켜질 수 있도록 된 것도 있는바, 이러한 것은 로터리자체에 변속기어가 붙박이로 부착되어 있어야 하므로 간단한 로터리의 가격을 상승시킴은 물른 구조도 복잡해질 뿐만 아니라 부품의 과다로 제조단가를 높이게 되는 결점이 있었다.In addition to the transmission structure for power take-off, some rotary transmission gears are installed on the rotary body so that the power transmitted through the chain from the power-in output can be shifted and rotated forward and reverse. Since transmission gears should be built-in, the cost of a simple rotary will not only increase the complexity of the structure but also increase the manufacturing cost due to excessive parts.

이에 본 고안은 상기와 같은 제반 결점들을 해소하기 위해 안출된 것으로, 간단한 구조로 되어 필요할 때 간편하게 착탈시켜 로터리축을 정. 역전시킬 수 있도록 된 동력 경운기의 로터리 변속기어장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above-mentioned shortcomings, it is a simple structure to easily remove when needed to determine the rotary shaft. It is an object of the present invention to provide a rotary transmission gear device of a power tiller capable of reversing.

상기와 같은 목적을 달성하기 위한 본 고안은, 동력경운기의 동력인출축과 로우터를 구동시키는 로터리축에 각각 2개의 상. 하부기어케이스가 결합되면서, 이들 기어케이스에는 다수의 베벨기어가 설치되어 동력의 전달방향을 전환시키도록 되어 있고, 상기 양쪽 기어케이스는 양쪽 기어 케이스에서 각각 뻗어나온 연결축을 매개로 연결되면서, 이들 연결축의 길이가 가변시켜질 수 있도록 스플라인결합 되면서 상대적으로 회전결합시켜질수 있게 되어 있다.The present invention for achieving the above object, two phases each in the rotary shaft for driving the power take-off shaft and the rotor of the power cultivator. As the lower gear case is coupled, a plurality of bevel gears are installed in the gear case to switch the transmission direction of the power, and the two gear cases are connected through the connecting shafts respectively extending from both gear cases. It can be spun coupled so that the length of the shaft can be changed while being relatively rotatable.

따라서 상기 동력경운기의 동력인출축에 결합된 상부 기어케이스를 앞. 뒤쪽에서 반대로 결합하게 되면 로터리축이 정. 역회전시켜지게 되고. 상기 상. 하부기어케이스를 동력인출축과 로터리축에 각각 반대방향으로 바꾸어 결합하게 되면 로터리축이 변속시켜지게 된다.Therefore, the front gear case coupled to the power take-off shaft of the power tiller. If you reverse from the rear, the rotary shaft will be positive. Will be reversed. Above phase. When the lower gear case is coupled to the power take-off shaft and the rotary shaft in opposite directions, the rotary shaft is shifted.

이하 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도 및 제2도는 각각 본 고안 로터리 변속기어장치가 부착된 평면도 및 개략정면도로서, 로터리 변속기어장치는 경운기의 동력인출축(1)과 로터리축(2)을 연결시켜 동력을 전달하는 변속기유닛(3)으로 구성되는바,이 변속기유닛(3)은 동력인출축(1)에 스플라인 결합되는 상부기어 케이스(4)와, 로터리축(2)에 스플라인결합되는 하부기어케이스(5)로 분리형성되어져 있다.1 and 2 are a plan view and a schematic front view of the rotary transmission gear device of the present invention, respectively, wherein the rotary transmission gear device transmits power by connecting the power take-off shaft 1 and the rotary shaft 2 of the tiller. The transmission unit (3) is divided into an upper gear case (4) that is splined to the power take-off shaft (1), and a lower gear case (5) that is splined to the rotary shaft (2). It is formed.

여기서 상부기어케이스(4)에는, 상기 동력인출축(1)이 좌우 양쪽방향에서 각각 삽입결합되면서 양단이 베어링(6)으로 지지되어 그 내부에 상기 동력인출축(1)의 외주면에 형성된 스플라인돌기를 끼워 수납하도록 스플라인홈(S)이 가공된 제1결합축(7)에 일체로 고정시켜진 제1수직베벨기어(8)와, 이 수직베벨기어(8)와 직각방향으로 맞물리면서 상기 상부기어케이스(4)의 바깥쪽으로 뻗어나와 그 상부가 베어링(9)에 지지되어진 제1연결축(10)에 일체로 고정시켜진 제1수평베벨기어(11)가 설치되고, 또 상기 하부 기어케이스(5)에는 로터리축(2)이 한쪽 방향에서는 삽입결합되면서 한쪽끝이 배어링(12)으로 지지되는 제2결합축(13)에 일체로 고정시켜진 제2수직베벨기어(14)와, 이 제2수직베벨기어(14)에 직각방향으로 맞물리면서 베어링(15)에 지지되어 이 하부기어케이스(5)의 바깥쪽으로 뻗어나와 있는 제2연결축(16)에 고정시켜진 제2수평베벨기어(17)가 설치되어 있다.Here, the spline protrusion formed on the outer circumferential surface of the power take-off shaft 1 inside the upper gear case 4 while the power take-off shaft 1 is inserted and coupled in both left and right directions, respectively, supported by a bearing 6. A first vertical bevel gear (8) integrally fixed to the first coupling shaft (7) on which the spline groove (S) is machined so as to be inserted into the first bevel gear (8), and the upper gear is engaged with the vertical bevel gear (8) at right angles. A first horizontal bevel gear 11 is provided which extends outwardly of the case 4 and is secured integrally to the first connecting shaft 10 supported by the bearing 9, and the lower gear case ( 5) a second vertical bevel gear 14 fixed integrally with the second coupling shaft 13 supported by the bearing 12 while the rotary shaft 2 is inserted and engaged in one direction; The lower gear is supported by the bearing 15 while meshing with the second vertical bevel gear 14 at right angles. Device has a second horizontal bevel gear 17 is secured to the binary second connecting shaft 16 and extending in the outside (5) is installed.

그리고 상기 상. 하부기어케이스(5,6)의 제1,2수평베벨기어(11,17)가 고정설치되어 바깥쪽으로 뻗어나온 제1 및 제2연결축(10,16)은. 각각 그 외주면에 길이방향으로 스플라인돌기가 형성되고 다수의 핀구멍(10a,16b)에 관통되면서 그 내면에 길이방향으로 스플라인홈이 형성된 원동형 연결부재(18)와 대향하는 반대쪽에서 각각삽입되어, 연결핀(19)을 상기 핀구멍(10a,10b)에 끼우게 되면 연결부재(18)와 제1 및 제2연결축(10,16)이 서로 결합되어 일체로 회전하도록 되어 있는바, 상기 연결부재(18)에는 다수의 연결구멍(18a)이 구비되어 상기 제1,2결합축(10,16)을 체결시켜주는 연결핀(19)의 간격이 변화시켜질 수 있도록 되어 있어서, 상기 동력인출축(1)과 로터리축(2) 사이의 거리가 다른 경운기에도 적용할 수 있도록 되어 있다.And said phase. The first and second horizontal bevel gears 11 and 17 of the lower gear case 5 and 6 are fixedly installed and extend outwardly. Spline protrusions are formed on the outer circumferential surface thereof in the longitudinal direction and penetrated through the plurality of pinholes 10a and 16b, respectively, and are inserted from opposite sides of the cylindrical connection member 18 having the spline grooves formed on the inner surface thereof in the longitudinal direction. When the connecting pin 19 is inserted into the pin holes 10a and 10b, the connecting member 18 and the first and second connecting shafts 10 and 16 are coupled to each other to rotate integrally. The member 18 is provided with a plurality of connection holes 18a so that the spacing of the connecting pins 19 for fastening the first and second coupling shafts 10 and 16 can be changed so that the power take-off can be changed. The distance between the shaft 1 and the rotary shaft 2 can be applied to other tillers.

또한 상기 제1결합축(7)에 설치된 제1수직베벨기어(8)의 직경은 제2결합축(13)에 설치된 제2수직베벨기어(14)의 직경보다 크거나 작게되어 있어서, 상기 제2결합축(13)의 회전 속도가 제1결합축(7)의 회전속도보다 빠르거나 늦어지게 됨으로써 상기 동력인출축(1)과 로터리축(2)에 상기 제1,2결합축(7,13)을 선택적으로 바꿔 결합시키게 되면 변속효과가 얻어질 수 있도록 되어 있다.In addition, the diameter of the first vertical bevel gear (8) provided on the first coupling shaft (7) is larger or smaller than the diameter of the second vertical bevel gear (14) provided on the second coupling shaft (13), The rotation speed of the second coupling shaft 13 is faster or slower than the rotation speed of the first coupling shaft 7, so that the first and second coupling shafts 7, By selectively changing 13), the shifting effect can be obtained.

다음에는 이상과 같이 구성된 본 고안의 작용에 대해 설명한다.Next, the operation of the present invention configured as described above will be described.

먼저 로터리축(2)을 정회전시킬 경우에는, 제3도에 도시된 상태로 상하부기어케이스(4,5)가 위치한 상태에서 동력인출축(1)에 상부케이스(4)의 제1결합축(7)을 끼움과 더불어 하부기어케이스(5)의 제2결합축(13)을 로터리축(2)에 끼워주게 되면 이들 축(1,7,2,13)이 상호 스플라인결합 시켜지게 된다.First, when the rotary shaft 2 is rotated forward, the first coupling shaft of the upper case 4 on the power take-off shaft 1 with the upper and lower gear cases 4, 5 in the state shown in FIG. In addition to fitting (7), when the second coupling shaft 13 of the lower gear case 5 is fitted to the rotary shaft 2, these shafts 1, 7, 2, 13 are splined to each other.

이어 동력이출축(1)을 시계방향(화살표 A방향)으로 회전시키면 제1결합축(7)과 함께 체1수직베벨기어(8)도 시계방향으로 회전되면서 이에 맞물려진 제1수평베벨기어(11) 및 제1연결축(10)이 반시계방향(화살표 B방향)으로 회전시켜지게 되고, 그에따라 이 제1연결축(10)에 연결부재(18)를 매개로 연결시켜진 제2연결축(16)과 이에 결합된 제2수평베밸기어(17)가 반시계방향으로 회전하면서 이에 맞물려진 제2수직베벨기어(14)와 제2결합축(13)을 시계방향으로 회전시키게 되는 결과, 이 제2결합축(13)에 스플라인 결합된 로터리축(2)이 시계방향(A방향), 즉 상기 동력인출축(1)과 같은 방향으로 회전하게 된다.Subsequently, when the power output shaft 1 is rotated clockwise (arrow A direction), the first horizontal bevel gear 8 also rotates clockwise along with the first coupling shaft 7 to engage the first horizontal bevel gear ( 11) and the first connecting shaft 10 is rotated in the counterclockwise direction (arrow B direction), and accordingly the second connection connected to the first connecting shaft 10 via the connecting member 18 As a result of rotating the shaft 16 and the second horizontal bevel gear 17 coupled thereto in a counterclockwise direction, the second vertical bevel gear 14 and the second coupling shaft 13 engaged thereto are rotated clockwise. The rotary shaft 2 splined to the second coupling shaft 13 rotates in a clockwise direction (A direction), that is, in the same direction as the power take-off shaft 1.

이때 만약 상기 로터리축(2)을 역회전시킬 경우에는, 상기 상부기어케이스(4)를 하부기어케이스(5)에 대해180°회전시켜 제1결합축(1)의 제1수직베벨기어(8)쪽을 동력인출축(1)에다 끼워주게 되면, 제4도로 도시된 상태가 된다. 즉 제3도와 같이 상기 동력인출축(1)을 시계방향(화살표 A방향)으로 회전시키면 제1결합축(7)과함께 제1수직베벨기어(8)도 시계방향으로 회전시켜지면서 이에 맞물려진 제1수평베벨기어(11) 및 제1연결축(10)을 시계방향(화살표 C방향)으로 회전시키계 되고, 그에 따라 제1연결축(10)에 연결부제(18)를 매개하여 연결시켜진 제2연결축(16)과 이에 결합된 제2수평베벨기어(17)가 시계방향으로 회전하게 되면서 이에 맞물려진 제2수직베벨기어(14)와 제2결합축(13)을 반시계방향으로 회전시키게 되는 결과, 이 제2결합축(13)에 스플라인결합된 로터리축(2)이 반시계방향(화살표 A반대방향), 즉 상기 동력인출축(1)과 반대방향으로 회전하게된다.In this case, if the rotary shaft 2 is rotated in reverse, the upper gear case 4 is rotated by 180 ° with respect to the lower gear case 5 so that the first vertical bevel gear 8 of the first coupling shaft 1 is rotated. ) Is inserted into the power take-off shaft 1, the state shown in the fourth degree. That is, as shown in FIG. 3, when the power take-off shaft 1 is rotated clockwise (arrow A direction), the first vertical bevel gear 8 is also rotated clockwise along with the first coupling shaft 7 and engaged with it. The first horizontal bevel gear 11 and the first connecting shaft 10 is rotated in a clockwise direction (arrow C direction), and accordingly connected to the first connecting shaft 10 via a connecting part 18. The second vertical bevel gear 14 and the second coupling shaft 13, which are engaged with the second second connecting shaft 16 and the second horizontal bevel gear 17 coupled thereto, rotate clockwise. As a result, the rotary shaft 2, which is splined to the second coupling shaft 13, is rotated counterclockwise (opposite the arrow A), that is, in the direction opposite to the power take-off shaft 1.

한편, 상기 로터리축(2)의 회전속도를 변속할 경우에는, 동력인출축 변속레버(도시안됨)를 1단에서 2단으로 조작하게 되면, 변속된 동력인출축(1)의 회전속도가 상기 설명에서와 같이 상.하부케이스(4,5)를 매개로 로터리축(2)으로 전달되어 이로터리축(2)을 2단으로 변속하게 된다.On the other hand, when the rotation speed of the rotary shaft 2 is shifted, when the power take-off shaft shift lever (not shown) is operated from one stage to two stages, the rotation speed of the shifted power take-off shaft 1 is increased. As described, the upper and lower cases 4 and 5 are transmitted to the rotary shaft 2 to shift the rotary shaft 2 in two stages.

이에 이 로터리축(2)을 3단 또는 4단으로 증속할 필요가 있을 경우에는 상기 기어케이스(4)와 하부기어케이스(5)의 위치를 바꿔주면 되는바, 즉 동력인출축(1)에 하부케이스(5)의 제2결합축(13)을 로터리축(2)에 상부케이스(4)의 제1결합축(7)을 각각 연결시켜주게 되면, 제2결합축(13)의 수직베벨기어(14)의 직경이 제1결합축(7)의 수직베벨기어(8)의 직경보다 작게 형성되어 있기 때문에 동력인출축(1)의 회전속도보다 로터리축(2)의 회전속도가 빨라져 증속되게 된다. 물른 이때 이와는 반대로 하부기어케이스(5)의 수직베벨기어(14)의 직경을 상부기어케이스(4)의 수직베벨기어(8)의 직경보다 커지게해서 로터리축(2)을 감속시킬수도 있다.When the rotary shaft 2 needs to be increased in three or four stages, the positions of the gear case 4 and the lower gear case 5 may be changed. That is, the power take-off shaft 1 When the second coupling shaft 13 of the lower case 5 connects the first coupling shaft 7 of the upper case 4 to the rotary shaft 2, respectively, the vertical bevel of the second coupling shaft 13 Since the diameter of the gear 14 is smaller than the diameter of the vertical bevel gear 8 of the first coupling shaft 7, the rotational speed of the rotary shaft 2 is faster than the rotational speed of the power take-off shaft 1 to increase the speed. Will be. At this time, on the contrary, the diameter of the vertical bevel gear 14 of the lower gear case 5 may be larger than the diameter of the vertical bevel gear 8 of the upper gear case 4 to decelerate the rotary shaft 2.

그리고, 본 고안은 동력인출축(1)과 로터리축(2) 사이의 거리가 다른 경운기에도 적용할 수 있는바, 예컨대 상기 동력인출축(1)과 로터리축(2) 사이 거리가 제3도에 도시된 상태의 거리보다 길 경우에는, 이에 대응되는 길이로 떨어져 형성된 상기 연결부재(18)의 아랫쪽 연결구멍(18a)과 제2연결축(16)의 핀구멍(16a)을 일치시키고 나서 이들 2개의 구멍(18a, 16a)에 연결핀(19)을 끼워 결합시키기만하면 상기 동력인출축(1)의 동력이 로터리축(2)에 전달될 수 있게 된다.In addition, the present invention can be applied to tillers with different distances between the power take-off shaft 1 and the rotary shaft 2, for example, the distance between the power take-off shaft 1 and the rotary shaft 2 is shown in FIG. In the case where the distance is longer than the distance shown in Fig. 2, the lower connection hole 18a of the connecting member 18 formed to be separated by a length corresponding thereto and the pin hole 16a of the second connecting shaft 16 coincide with each other. The power of the power take-off shaft 1 can be transmitted to the rotary shaft 2 by simply fitting the connecting pins 19 to the two holes 18a and 16a.

이상 설명한 본 고안에 의하면, 벨트나 풀리등과 같은 동력전달수단이 필요없이 베벨기어와 축으로만 조합시켜진 변속기로 동력인출축(1)의 동력을 정. 역회전시키거나 변속시켜 로터리축(2)으로 전달할 수 있도록 되어있어서, 구조가 간단할 뿐만 아니라 상기 동력인출축(1)과 로터리축(2) 사이의 거리가 다른 경운기에도 적용시킬 수 있는 효과가 있다.According to the present invention described above, the power take-off shaft 1 is fixed with a transmission that is combined only with the bevel gear and the shaft without the need for a power transmission means such as a belt or a pulley. It is designed to be rotated or shifted to the rotary shaft 2 so that the structure is not only simple, but also has an effect that can be applied to a cultivator having a different distance between the power take-off shaft 1 and the rotary shaft 2. have.
