본 고안은 기어를 이용한 감속장치에 관한것이며, 동력회전측에 형성된 태양기어의 외곽에 1조로 구성된 유성기어를 형성하고 그 외곽으로 고정인터날기어와 구동인터날기어를 형성하여 태양기어의 회전력을 태양기어의 잇수와 고정인터날기어의 각잇수에 비례하여 감속되고 또 고정인터날기어보다 잇수가 적고 유성기어 수량만큼 부족한 잇수(齒數)를 가진 구동인터날기어에서 2차감속되며 출력회전이 고율로 감속되는 효과를 얻고자하는 것이다.The present invention relates to a reduction gear using a gear, and form a set of planetary gears on the outer side of the sun gear formed on the power rotation side, and to form a fixed internal gear and a drive internal gear to the outer side to improve the rotational force of the sun gear It is decelerated in proportion to the number of teeth of the sun gear and the angle of the fixed gear, and the second speed is reduced in the drive gear which has less teeth than the fixed gear and less than the number of planetary gears. To achieve the effect of slowing down.

종래에는 동력회전축의 회전수를 태양기어에서 유성기어를 통하여 고정인터날기어에 전달되고 감속은 고정 인터날기어의 잇수와 태양기어의 잇수에 비례하여 감속된 회전수를 유성기어의 축간을 연결시킨 하우징의 출력으로 사용하게 된다.Conventionally, the rotational speed of the power rotation shaft is transmitted from the sun gear to the fixed internal gear via the planetary gear, and the deceleration is connected to the planetary gear shaft by the reduced speed in proportion to the number of teeth of the fixed internal gear and the number of the sun gear. It will be used as the output of the housing.

이로인하여 태양기어의 잇수와 인터날기어의 잇수에 비례하여 감속이 되기때문에 이는 감속비율이 낮으므로 감속비를 고율로 높이고자 할때 다단으로 하거나 또는 인터날기어의 잇수를 많게하고 태양기어의 잇수를 작게 하여 감속비를 높이고 있으나 이는 잇수비만큼 면압마찰이 크게되어 회전력의 효율이 저하되고 또 워엄과 워엄 기어에 의한 감속은 효율이 매우 낮고 기어마모가 심하고 기어의 직경과 잇수비에 의한 감속장치는 효율은 높으나 고율의 감속 효율을 얻을수 없는 결점이 있고 특히 이들의 감속기는 출력축에서 부하가 발생되면 출력축에서 입력축으로 역회전을 일으키게 되므로 이를 방지하는 별도의 브레이크 장치가 요구되는 결점이 있었다.Because of this, deceleration is proportional to the number of teeth of the sun gear and the number of the teeth of the internal gear, so the deceleration ratio is low. Therefore, if you want to increase the reduction ratio to a high rate, increase the number of teeth of the internal gear or increase the number of teeth of the sun gear. Although the reduction ratio is increased, the surface friction is increased as much as the tooth ratio, so the efficiency of rotational force is lowered, and the deceleration by worm and worm gear is very low efficiency, the gear wear is severe, and the gear ratio is reduced by the diameter and tooth ratio. Although it is high, there is a drawback that high rate deceleration efficiency cannot be obtained. In particular, these reducers cause a reverse rotation from the output shaft to the input shaft when a load is generated on the output shaft.

본 고안은 이와같은 종래의 제반결점을 해소하고 고율의 감속 밋 브레이크 기능이 포함된 장치를 고안한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves the above-mentioned general drawbacks and devised a device including a high rate deceleration mit brake function, which will be described in detail with reference to the accompanying drawings.

통상의 동력회전축(1)을 몸체(2)에서 베어링(3)으로 지지하고, 동력회전축(1)에 형성한 태양기어(1a)의 외곽 몸체(2)에는 고정인터날기어(4)를 형성하고 그내에 여러개의 유성기어(5)를 형성.유성기어(5)의 축(5a)을 1조가되게 하우징(6)으로 상호 결합하고 유성기어(5)와 맞물리는 구동인터날기어(7)를 가진 출력축(8)을 형성한 출력축(8)의 내측에 동력회전축(1)이 끼워지는 삽지홈(9)을 형성, 베어링(10)으로 지지결합하면서 구동인터날기어(7)에 고정인터날기어(4)보다 잇수가 적고 유성기어(5)수량과 동일한 잇수만큼 부족한 잇수를 형성한 것이다.A conventional power rotary shaft 1 is supported from the body 2 to the bearing 3, and a fixed internal gear 4 is formed on the outer body 2 of the sun gear 1a formed on the power rotary shaft 1. And a plurality of planetary gears 5 formed therein. A drive internal gear 7 which mutually couples the shaft 5a of the planetary gear 5 to the housing 6 and engages with the planetary gear 5. An insertion groove 9 into which the power rotating shaft 1 is fitted is formed inside the output shaft 8 on which the output shaft 8 having the output shaft 8 is formed, and is fixed to the drive internal gear 7 while being supported by the bearing 10. The number of teeth is smaller than that of the flying gear (4), and the number of teeth that is the same as the number of planetary gears (5) is insufficient.

미설명 부호 11은 케이스이다.Reference numeral 11 is a case.

이상과 같이 구성된 본 고안의 작용효과를 설명하면 다옴과 같다.Referring to the effect of the present invention configured as described above is as follows.

통상 모터나, 엔진등의 고속회전력을 동력회전축(1)에서 전달받아 이를 동력회전축(1)의 회전을 태양기어(1a)와 맞물리는 1조의 유성기어(5)에 의해 고정인터날기어(4)에 전달하면 하우징(6)에 의하여 축(5a)이 결합된 한조의 유성기어(5)는 동력회전축(1)을 선회하면서 고정인터날기어(4)에 전달되어 동력회전축(1)의 태양기어(1a)와 고정인터날기어(4)의 잇수비에 의하여 감속이 이루어지게 된다.In general, a high speed rotational power such as a motor, an engine, etc. is transmitted from the power rotating shaft 1 and the fixed internal gear 4 is formed by a set of planetary gears 5 that engage the rotation of the power rotating shaft 1 with the sun gear 1a. ), A set of planetary gears 5 coupled to the shaft 5a by the housing 6 is transmitted to the fixed internal gear 4 while turning the power rotating shaft 1 so that the sun of the power rotating shaft 1 is rotated. Deceleration is achieved by the number ratio of the gear 1a and the fixed inter-gear gear 4.

이와같이 감속이 이루어진 회전력은 고정인터날기어(4)보다 잇수가 적고 유성기어(5)수량과 동일한 잇수만큼 부족한 잇수를 가진 구동인터날기어(7)에서 다시 고율로 감속이된다.In this way, the decelerating rotational force is decelerated again at a high rate in the drive internal gear 7 having fewer teeth than the fixed internal gear 4 and the same number of teeth as the number of planetary gears 5.

즉 고정인터날기어(4)에서 1조의 유성기어(5)가 한바퀴 회전하면 구동인터날기어(7)는 고정인터날기어(4) 보다 부족한 잇수만큼 회전이 되어 감속이 고율로 이루어지게 된다.In other words, when a set of planetary gears 5 rotate one turn in the fixed gear 4, the drive gear 7 is rotated by the number of teeth less than the fixed gear 4, so that the deceleration is performed at a high rate.

또 이와같이 고율로 감속이 이루어져 감속된 회전력이 출력축(8)으로 전달되는 과정에서 출력축(8)보다 강한 부하가 발생되면 출력축(8)에서는 역회전의 힘이 발생되는데 이때에는 동력회전축(1)에 형성된 태양기어(10)는 고정상태가 되고 몸체(2)에 고정된 고정인터날기어(4)와 출력축(8)의 구동인터날기어(7)의 일직선 상으로 된 기어의 치저(齒低)에 유성기어(5)의 치고(齒高)가 서로 맞물린 상태로 유성기어(5)의 수만큼 고정인터날기어 (4)에 유성기어 (5)와 구동인터날기어(7)가 서로 맞물려 있게되어 출력축(8)의 고정인터날기어(4)는 역회전이 불가능하고 정지상태가 된다.In addition, when a load is generated higher than the output shaft 8 while the deceleration is performed at a high rate and the reduced rotational force is transmitted to the output shaft 8, a force of reverse rotation is generated at the output shaft 8. The formed sun gear 10 is fixed and the gears of the gears which are in a straight line between the fixed internal gear 4 fixed to the body 2 and the drive internal gear 7 of the output shaft 8 are fixed. The planetary gears 5 and the driving gears 7 are engaged with the fixed internal gears 4 by the number of the planetary gears 5 with the high gears of the planetary gears 5 engaged with each other. As a result, the fixed internal gear 4 of the output shaft 8 cannot be reversely rotated and is stopped.

또, 동력회전축(1)을 사용하다가 회전을 중단하게 되면 출력축(8)은 자동으로 정지상태가 되고 이때 역회전이 힘이 발생되더라도 역으로 회전되지 못하고 정지상태가 된다.In addition, when the rotation is stopped while using the power rotating shaft (1), the output shaft (8) is automatically stopped and at this time, even if the reverse rotation force is generated, the reverse rotation is not stopped.

이와같이 본 고안은 동력회전축(1)에 형성된 태양기어(1a)와 고정인터날기어(4)에서 감속하고, 또 고정인터날기어(4)와 구동인터날기어(7)에서 고율로 감속되어 출력축(8)으로 전달된다.In this way, the present invention decelerates in the sun gear 1a and the fixed internal gear 4 formed on the power rotating shaft 1, and decelerates at a high rate in the fixed internal gear 4 and the drive internal gear 7 to the output shaft. Is passed to (8).

따라서 이상과 같은 본 고안은 동력회전축에 형성된 태양기어와 고정인터날기어와의 잇수에 비례하여 감속되고 또 고정인터날기어보다 잇수가 적고 유성기어 수량과 동일한 잇수만큼 부족한 잇수를 가진 구동인터날기어에서 감속되어 고율의 감속을 얻을 수 있고 특히 동력회전축에서 회전력이 전달되지 않거나 출력축보다 강한 부하의 역회전이 발생될때에는 자동으로 정지되므로 역회전을 방지하는 브레이크장치 없이도 사용할수 있게 되므로 각종기계나 기구등 고율의 감속이 소요되는 장치에서 편리하게 사용할수 있고 또 소형, 경량화하여 호이스트등 움직이는 기구나 장치에서도 사용이 편리한 실용적인 특징이 있다.Therefore, the present invention as described above has a reduction in proportion to the number of teeth of the sun gear and the fixed internal gear formed on the power rotating shaft, and the number of teeth less than the number of the fixed gear and the same number of teeth as the number of planetary gears. Can be used without brake device to prevent reverse rotation, because it automatically stops when the rotational force is not transmitted from the power shaft or when the reverse rotation of the load stronger than the output shaft occurs. It can be conveniently used in high speed deceleration devices, and has a practical feature that makes it easy to use in moving devices such as hoists.
