본 고안은 감속기에 관한 것으로, 입력축과 출력축의 중심선에 유성치차의 중심선이 평행하게 입력측고정태양치차와 출력축태양치차에 유성치차를 각각 치합시키되 유성치차축을 입력축에 축착된 크랭크판에 축설하여 입력측고정태양치차와 이에 치합된 유성치차 및 출력축 태양치차와 이에 치합된 유성치차와 이빨수 차이로 인한 감속비에 해당하는 감속력을 출력측에 전달토록 구성하므로서 동력효율을 높이고, 소형으로 감속기의 제작원가를 줄일 수 있도록 안출한 것이다.The present invention relates to a speed reducer, and the planetary gear shaft is fitted to the center shaft of the input shaft and the output shaft in parallel with the planetary gear and the planetary gear shaft is fitted to the crank plate attached to the input shaft. Solar gear and planetary gearbox and output shaft connected to it Solar gear and planetary gearbox and tooth gear connected to it reduce gear ratio corresponding to gear ratio to output side to increase power efficiency and reduce manufacturing cost of small gearbox To make it happen.

종래에도 감속기로서 여러가지가 있으나 이들은 감속비에 따라 그 크기가 다르며, 감속기가 큰 경우일수록 크기가 커서 제작원가의 상승요인이 되므로 본 고안의 이러한 점을 감안하여 안출한 것인바 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Although there are various types of reduction gears according to the related art, they vary in size depending on the reduction ratio, and the larger the reduction gear is, the larger the size becomes, which is a rising factor of the manufacturing cost. The explanation is as follows.

입력축(1)과 출력축(7)의 중심선(1a)에 유성치차축(5)의 중심선(5a)이 평행하게 입력축고정태양치차(6)와 출력축태양치차(8)에 유성치차(3) 및 (4)를 각각 치합시키되 유성치차축(5)을 입력축(1)에 축착된 크랭크판(2)에 축설하여 입력축고정태양치차(6)와 이에 치합된 유성치차(3) 및 출력축태양치차(8)와 이에 치합된 유성치차(4)의 이빨수 차이로 인한 감속비에 해당하는 감속력을 출력축에 전달토록 구성하였다.The planetary gear 3 and the input shaft fixed sun gear 6 and the output shaft sun gear 8 are parallel to the center line 5a of the planetary gear shaft 5 on the center line 1a of the input shaft 1 and the output shaft 7. (4), respectively, but the planetary gear shaft (5) is installed in the crank plate (2) in contact with the input shaft (1), the input shaft fixed sun gear (6), the planetary gear (3) and the output shaft solar gear ( 8) and the reduction force corresponding to the reduction ratio due to the tooth number difference between the planetary gears 4 engaged with it are configured to transmit to the output shaft.

그리고 입력축고정태양치차(6)는 감속기 케이스(9)에 고정되어 있으며, 입력축(1)의 선단(1b)은 출력축(7)의 선단(7a)에 끼워 축지시키므로서 입력축(1)과 출력축(7)을 축지시키는 구조를 간소화하여 감속기의 크기를 극소화시켰다.And the input shaft fixed sun gear (6) is fixed to the reducer case (9), the front end (1b) of the input shaft (1) is fitted to the front end (7a) of the output shaft (7) while the input shaft (1) and the output shaft ( Reduced size of the reducer by simplifying the structure of the damper.

이와같은 본 고안은 입력축(1)의 회전으로 출력축(2)이 회전하면 유성치차(3),(4)는 입력축고정태양치차(6)와 출력축태양치차(8) 주위를 공전함과 동시에 유성치차(3),(4)와 출력축태양치차(8)는 자전을 하게 되는데 유성치차(3)의 자전하는 회전수는(입력측고정태양치차 주위를 1회전할때) 입력축고정태양치차(6) 이빨수(An)에 유성치차(3)의 이빨수(Bn)로 나눈 것이 되고 유성치차(4)의 회전수와 같다.The present invention has a planetary gear (3), (4) revolves around the input shaft fixed solar gear (6) and the output shaft solar gear (8) when the output shaft (2) is rotated by the rotation of the input shaft (1) The gears (3) and (4) and the output shaft solar gear (8) rotate. The rotational speed of the planetary gear (3) is rotated (when one rotation around the input fixed solar gear). The tooth number An is divided by the tooth number Bn of the planetary gear 3 and is equal to the rotation speed of the planetary gear 4.

(즉,유성치차(4)의 회전수)이 유성치차(4)의 회전수에 유성치차(4)의 이빨수를 곱한 이빨수가 (Cn) 출력축태양치차(8)의 이빨수(Dn)와 같으면 출력축태양치차(8)는 회전하지 않으나 이빨수가 같지 않으면 그 차이만큼 출력축 유성치차(4)가 출력축태양치차(8)를 끌고 회전하거나 뒤로 밀면서 회전시킨다.(In other words, The number of teeth of the planetary gear 4 multiplied by the number of teeth of the planetary gear 4 and the number of teeth of the planetary gear 4 Cn) If the tooth number Dn of the output shaft sun gear 8 is the same, the output shaft sun gear 8 does not rotate, but if the teeth are not the same, the output shaft planetary gear 4 pulls and rotates the output shaft sun gear 8 by the difference. Push back and rotate.

고로 출력축태양치차(8)가 1회전하기 위해서는 유성치차(4)의 회전수에 유성치차(4)의 이빨수를 곱한 이빨수 차이로서 나눈 것이다.Therefore, in order for the output shaft solar gear 8 to rotate one time, the number of revolutions of the planetary gear 4 is divided by the number of teeth multiplied by the number of teeth of the planetary gear 4.

이러한 관계로 입력축고정태양치차(6)와 유성치차(3), 유성치차(4)와 출력축태양치차(8) 사이에는 아래의 수식이 성립되며, 따라서 각 치차의 이빨수에 의한 입력축(1)의 회전수가 감속되어 출력축(7)에 전달된다.In this relation, the following equation is established between the fixed shaft sun gear 6 and the planetary gear 3, the planetary gear 4 and the output shaft sun gear 8, and thus the input shaft 1 by the number of teeth of each gear The rotational speed of the motor is decelerated and transmitted to the output shaft 7.

주; An : 입력축고정태양치차(6)의 이빨수, Bn : 유성치차(3)의 이빨수, Cn : 유성치차(4)의 이빨수, Dn : 태양치차(8)의 이빨수, (단, 감속기의 부호가 부(-)로 나타날때는 입력축의 회전방향과 출력축의 회전방향이 반대임을 뜻한다)week; An: teeth of input shaft fixed solar gear (6), Bn: teeth of planetary gear (3), Cn: teeth of planetary gear (4), Dn: teeth of solar gear (8), (reduction gear When the sign is negative, it means that the direction of rotation of input shaft is opposite to that of output shaft.)

예:An=11매, Bn=10매, Cn=9매, Dn=10매 일 때,이 된다.Example: When An = 11 sheets, Bn = 10 sheets, Cn = 9 sheets, Dn = 10 sheets, Becomes

이와 같이 본 고안은 입력축(1)에 축착된 출력축(2)으로 유성치차(3) 및 (4)를 입력축고정태양치차(6)와 출력축태양치차(8) 주위를 공전시킴과 동시에 자전시키면서 입력축고정태양치차(6)와 이에 치합된 유성치차(3) 및 출력축태양치차(8)와 이에 치합된 유성치차(4)의 이빨수 차이로 인한 감속기에 해당하는 감속력을 출력축(7)에 전달할 수 있으므로 높은 감속비일수록 감속기의 크기는 작게할 수 있으므로 제작비가 절감되어 원가가 저렴한 감속기를 제공할 수 있는 것이다.As described above, the present invention rotates the planetary gears 3 and 4 around the input shaft fixed sun gear 6 and the output shaft sun gear 8 with the output shaft 2 condensed on the input shaft 1 while rotating the input shaft. The deceleration force corresponding to the speed reducer due to the tooth number difference between the fixed sun gear 6 and the planetary gear 3 and the output shaft sun gear 8 and the planetary gear 4 engaged thereto is to be transmitted to the output shaft 7. Therefore, the higher the reduction ratio, the smaller the size of the reducer can be, so that the manufacturing cost is reduced to provide a cost-effective reducer.
