Abstract

The speed reducer has a simple gear mechanism, and a plurality of planetary gears so that it can reduce the size of the gear box and transmit a large force. While sun gears (1,1'), fixed to an input shaft (4), rotate, the sun gear (1) makes a speed reduction guidance part (B) rotate and the other sun gear (1') makes the other speed reduction guidance part (A) rotate. As a result, the two rotational guidance parts (B,A) offset each other in the part (C), and the remaining rotation is guided to idling.

Description

차동기어 고감속기Differential Gear High Reducer

제1도 차동기어 고감속기의 종단면도.1 is a longitudinal sectional view of a differential gear high reduction gear.

제2도 기어 열을 예시한 동력전달과 회전 방향을 예시한 개략 계통도.2 Schematic schematic diagram illustrating power transmission and rotational direction illustrating gear trains.

본 발명은 산업용 기계에 사용하는 고감속기에 관한 것이다.The present invention relates to a high speed reducer for use in industrial machinery.

종래의 고감속기는 제작상의 어려운 난점과 고감속을 유도할때 효율이 저하되고 부피가 커서 큰 장소와 미관이 좋지 못한 점이 있었으나 본 발명은 간단한 기구학적 방법으로 종래의 고감속기에 결점을 완전 보안한 것이다.Conventional high reduction gears have a disadvantage in efficiency and low volume when inducing difficult difficulties and high deceleration in manufacturing. will be.

본 발명의 고감속기에 구동장치를 설명하면 입력축(4)과 출력축(5)이 중심위치의 일직선상에 있으면서 태양기어(1)(1')는 입력축(4)에 고정되어 있어 입력축(4)가 회전을 하면 같이 태양기어(1)(1')는 돌게되어 있다.Referring to the driving apparatus of the high speed reducer of the present invention, the sun gear (1) (1 ') is fixed to the input shaft (4) while the input shaft (4) and the output shaft (5) are in a straight line at the center position. When rotating, the sun gears 1 and 1 'are turned together.

유성기어들(3-1)(3-2)은 회전할 수 있게 (자전)기어 박스(8)에 핀(7)로 고정되어 있어 태양기어(1)로 동력을 받아 정비례의 정확한 감속을 유도기어(6)에 전하여 감속을 유도하여 준다. (편의상 도면 제2도에서 "B"를 입력 유도부분이라 칭한다) 또 한편 유성기어(2-1)(2-2)는 출력축(5)에 회전할 수 있게 핀(9)로 고정되어 있고 출력축(5)도 기어박스(8)에 회전을 할 수 있게(여기서 태양기어를 중심으로 공전) 베어링으로 고정되어 유도기어(6')와 가감회전을 유도하게 되어 있다. (편의상 도면 제2도에서 "A"를 출력 유도부분이라 칭한다.)Planetary gears (3-1) (3-2) is able to rotate (rotate) derived an exact proportional deceleration of a fixed pin (7) to the gearbox (8) it receives the power to the sun gear (1) Induces deceleration by transmitting to gear (6). (For convenience referred to as a first drawing part 2 also induce a type "B" from) the other hand the planetary gear (2-1) (2-2) is fixed to the pin (9) can be rotated with the output shaft 5 and output shaft (5) is also fixed to the gear box (8, the revolving around the sun gear) to the gear box (8) to induce the induction gear (6 ') and the acceleration and deceleration. ("A" is referred to as an output induction part in FIG. 2 for convenience.)

도면 제2도에서 입력축(4)에 태양기어(1)과 (1')가 고정되어 입력축(4)가 회전을 하면 태양기어(1)과 (1')는 유성기어(2)(3)에 각각 "A" 부분과 B부분으로 C부분경계에서 나누어 회전전동시켜 주게 된다.In FIG. 2, when the sun gears 1 and 1 'are fixed to the input shaft 4 and the input shaft 4 rotates, the sun gears 1 and 1' are planetary gears 2 and 3, respectively. The motor is divided into the "A" part and the B part at the C part boundary, respectively.

B부분에서 태앙기어(1)는 여러개의 유성기어(3)는 기어박스(8)에 핀(7)로 고정되어 있어 정확한 감속(정비례감속)을 유도하여 유도기어(6)을 감속시켜 준다.In part B, the gears 1 are fixed to the gearbox 8 by a plurality of planetary gears 3, so that the induction gear 6 is reduced by inducing an accurate deceleration (proportional deceleration).

또 한편 "A" 부분에서 유성기어(2-1)(2-2)들은 출력측에 (5) 핀(9)로 회전할 수 있게 되어 있으면서 출력축(5)은 기어박스(8)에 베어링으로 지지 고정하여 입력축(4)에 고정되 태양기어(1')를 중심으로 회전하게 되어 있어 유성기어(2-1)(2-2)는 자전을 유도하면서 유도기어(6')에 회전전동된 "B" 부분 감속 회전비와 가감을 하여 출력축(5)을 돌려주게 된다(이때 공전하는 회전비는 출력축에 감속되는 회전비이다). 도면 제2도에서 표시한 바와 같이 동력 전달방향과 "A"쪽에서와 "B"쪽 회전방향이 같으므로 "A"와 "B"에 감속비가 상쇄되면서 감속을 유도하는 작동원리를 설명하면 다음과 같다.On the other hand the planetary gear (2-1), (2-2) are at the output (5) is able to rotate while the pin (9), the output shaft 5 is supported in bearings in the gearbox (8) in the "A" portion Fixed to the input shaft (4) to rotate around the sun gear (1 ') planetary gear (2 -1 ) (2 -2 ) is rotated to the induction gear (6') while inducing rotation. The output shaft 5 is returned by adding and subtracting the B ″ partial deceleration rotation ratio (the revolution ratio being idle is the rotation ratio that is decelerated to the output shaft). As shown in FIG. 2, since the direction of power transmission is the same as the direction of rotation in the "A" side and the "B" side, the operation principle of inducing the deceleration while canceling the reduction ratios in the "A" and "B" will be described as follows. same.

입력축(4)에 고정된 태양기어(1)과 (1')가 동시에 회전하여 태양기어(1)는 유성기어(3-1)(3-2)에 전동되어 유도기어(6)에 정확한 임의의 감속회전을 하게 하고 또다른 태양기어(1')는 유성기어(2-1)(2-2)를 임의의 감속 회전을 하게 하고 유도기어(6')와 유성기어(2-1)(2-2)는 임의 회전비를 가질때 "B" 부분의 감속비와 "A" 부분의 감속비가 많을때는 압력축(4)의 회전방향과 같아지고 "B"부분의 감속비와 "A"부분의 감속비가 같을 때는 입력축(4)가 회전하더라도 입력축(5)은 회전하지 않고 0회전하게 된다. 또 "B" 부분의 감속비보다 "A" 부분의 감속비가 적을때는 입력축(4)의 회전방향에 반대방향으로 출력축(5)은 회전하게 된다.The sun gear (1) and (1 ') fixed to the input shaft (4) are rotated at the same time, so that the sun gear (1) is transmitted to the planetary gear ( 3-1 ) ( 3-2 ) and is correct to the induction gear (6). Decelerating rotation and another sun gear (1 ') causes planetary gear (2 -1 ) (2 -2 ) to be arbitrarily decelerating and induction gear (6') and planetary gear (2 -1 ) ( 2-2) is gajilttae arbitrary speed ratio "B" when there are many gear ratio of the gear ratio and "a" part of the portion becomes equal to the rotation direction of the pressure shaft (4) of the speed reduction ratio of the reduction ratio and "a" part of the "B" portion In the same case, even if the input shaft 4 rotates, the input shaft 5 does not rotate but rotates zero. When the reduction ratio of the "A" portion is less than the reduction ratio of the "B" portion, the output shaft 5 rotates in the direction opposite to the rotation direction of the input shaft 4.

즉 입력축(4)에 태양기어(1) (1')가 같은 방향으로 회전하므로 서로 회전이 상쇄되고 가감된 나머지 회전을 공전으로 유도하여 출력축(5)을 회전시켜 입력축(4)에 전동 회전비를 감속 회전한다.That is, since the sun gears 1 and 1 'rotate on the input shaft 4 in the same direction, the rotations cancel each other and guide the remaining rotations into the idle to rotate the output shaft 5 to provide an electric rotation ratio to the input shaft 4. Deceleration Rotate

"A" 부분의 회전비와 "B" 부분의 회전 감속비에 차이가 적을수록 큰 감속비를 얻을 수 있어 간결한 기어배열은 기어박스의 크기를 축소하며 미관과 재료손실 가공비용을 줄일 수 있고 여러개의 유성기어는 큰 힘을 전달하기에 용이한 합리적 기어배열로 높은 기계 효율을 얻을 수 있는 특징의 차동기어 고감속기The smaller the difference between the rotation ratio of the "A" part and the rotation reduction ratio of the "B" part, the larger the reduction ratio can be obtained.The compact gear arrangement reduces the size of the gearbox, reduces the aesthetics and material loss processing costs, and creates a number of planetary gears. Is a differential gear high reduction gear that can achieve high mechanical efficiency with a rational gear arrangement that is easy to transmit large force.
