본 발명은 감속기에 관한 것으로, 웜기어와 헬리컬기어를 결합하여 모터에 의해 전달되는 동력의 속도는 낮추며 토크를 올리는 감속기에 관한 것이다. The present invention relates to a speed reducer, by combining a worm gear and a helical gear, and a speed reducer for lowering the speed of power transmitted by a motor.

상기 감속기는 콘베이어, 산업기계 등의 공작기계에 설치되어 사용된다.The speed reducer is installed and used in machine tools such as conveyors and industrial machines.

본 발명의 감속기는 하우징(110)과, 상기 하우징(110) 내부에 설치되는 헬리컬기어(120)와, 헬리컬기어(120)의 전, 후방에 각각 설치되는 전, 후방웜기어(130, 140)와, 상기 하우징(110)의 외면에 설치되어 전방웜기어(130) 또는 후방웜기어(140)에 동력을 전달하는 모터(150)로 이루어진다.The speed reducer of the present invention includes a housing 110, a helical gear 120 installed inside the housing 110, and a front and rear worm gears 130 and 140 installed in front and rear of the helical gear 120, respectively. The motor 150 is installed on the outer surface of the housing 110 to transmit power to the front worm gear 130 or the rear worm gear 140.

상기 하우징은 내부에 공간부가 형성된 육면체 형상이며, 상기 하우징의 내부 중심에는 헬리컬기어가 설치되되, 상기 헬리컬기어의 하면은 하우징의 내부 하면과 수평이 되도록 설치된다.The housing has a hexahedral shape having a space formed therein, and a helical gear is installed at an inner center of the housing, and a lower surface of the helical gear is installed to be horizontal with an inner lower surface of the housing.

그리고 상기 헬리컬기어의 전, 후방에는 각각 전, 후방웜기어가 설치되되, 상기 전, 후방웜기어 축은 하우징의 좌, 우측면에 각각 베어링에 의해 설치된다.The front and rear worm gears are installed at the front and rear of the helical gear, respectively, and the front and rear worm gear shafts are installed by bearings on the left and right sides of the housing, respectively.

그리고 상기 전방웜기어 또는 후방웜기어에는 모터가 설치되어, 상기 전방웜기어 또는 후방웜기어에 동력을 전달한다.The motor is installed at the front worm gear or the rear worm gear to transmit power to the front worm gear or the rear worm gear.

본 발명에서는 전방웜기어에 모터의 동력이 전달되는 것으로 설명한다.In the present invention will be described as the power of the motor is transmitted to the front worm gear.

상기 전방웜기어의 좌측은 하우징의 좌측 내벽면에 베어링에 의해 회전가능하게 설치되고, 우측은 하우징의 우측 내벽면에 베어링에 의해 회전가능하게 설치되되, 상기 하우징의 우측 내벽면에 전방웜기어의 우측에는 모터의 회전축과 연결된다.The left side of the front worm gear is rotatably installed by a bearing on the left inner wall of the housing, the right side is rotatably installed by the bearing on the right inner wall of the housing, the right side of the front worm gear on the right inner wall of the housing It is connected to the rotating shaft of the motor.

이에, 상기 모터가 작동하면, 모터의 회전축이 회전하고, 상기 모터의 회전축은 전방웜기어에 동력을 전달한다.Thus, when the motor is operated, the rotating shaft of the motor rotates, the rotating shaft of the motor transmits power to the front worm gear.

상기 후방웜기어의 좌측은 하우징의 좌측 내벽면에 베어링에 의해 회전가능하게 설치되고, 우측은 하우징의 우측 내벽면에 베어링에 의해 회전가능하게 설치된다.The left side of the rear worm gear is rotatably installed on the left inner wall of the housing by the bearing, and the right side is rotatably installed on the right inner wall of the housing by the bearing.

그리고 상기 전방웜기어에 동력이 전달되면, 상기 전방웜기어는 회전하게 되고, 상기 전방웜기어는 헬리컬기어를 회전시키게 된다.When power is transmitted to the front worm gear, the front worm gear rotates, and the front worm gear rotates the helical gear.

이때, 상기 헬리컬기어의 후방에도 후방웜기어가 설치되어 감속기의 동력전달도중 손실되는 동력을 줄일 수 있다.At this time, the rear worm gear is installed in the rear of the helical gear can reduce the power lost during the power transmission of the reducer.

즉, 상기 헬리컬기어의 전방에만 전방웜기어를 설치하게되면, 정방웜기에서 헬리컬기어로 동력이 전달 될 시, 헬리컬기어와 전방웜기어 간의 기어결합중 틈이 발생하게 되어 어느 정도의 동력손실이 일어나게 된다.That is, if the front worm gear is installed only in front of the helical gear, when power is transmitted from the helical gear to the square worm, a gap is generated during the gear coupling between the helical gear and the front worm gear, thereby causing a certain power loss.

이에, 상기 헬리컬기어는 전방웜기어와 후방원기어가 전, 후방에 각각 설치되어 있으므로, 모터의 동력을 전달받아 전방웜기어가 회전하고, 상기 전방웜기어가 헬리컬기어에 동력을 전달하되, 상기 헬리컬기어의 후방에는 후방웜기어가 설치되어 있어, 상기 헬리컬기어는 전, 후방웜기어 사이에서 기어결합되어 있으므로, 기어결합중 틈이 발생되지 않아 동력이 손실되지 않게 되는 것이다.Thus, since the helical gear is provided with the front worm gear and the rear original gear, respectively, the front worm gear is rotated by the power of the motor, and the front worm gear transmits the power to the helical gear. Since the rear worm gear is installed at the rear, the helical gear is geared between the front and rear worm gears, so that no gap is generated during the gear coupling so that power is not lost.

한편, 상기 헬리컬기어(120)의 전, 후방에 설치되는 전, 후방웜기어(130, 140)는 장구형 웜기어를 사용하되, 상기 전, 후방웜기어(130, 140)의 웜기어기어이빨(131, 141)에는 곡면돌출부(131-1, 141-2)가 형성되어 있다.Meanwhile, the front and rear worm gears 130 and 140 which are installed at the front and rear of the helical gear 120 use long worm gears, but the worm gear teeth 131 and 141 of the front and rear worm gears 130 and 140. ), Curved projections 131-1 and 141-2 are formed.

상기 전방웜기어는 길이방향으로 길게 형성되는 축(132)과, 상기 축(132)의 외주연에 형성되는 웜기어기어이빨(131)로 이루어지되, 상기 전방웜기어의 웜기어기어이빨은 축의 길이방향을 따라 외주연을 감싸며 나선형으로 형성된다.The front worm gear is composed of a shaft 132 formed long in the longitudinal direction and the worm gear teeth 131 formed on the outer periphery of the shaft 132, the worm gear teeth of the front worm gear is along the longitudinal direction of the shaft It surrounds the outer periphery and is formed spirally.

상기 축은 단면이 좌측에서 우측으로, 1수평부(132-1), 제1경사부(132-2), 기어부(132-3), 제2경사부(132-4), 제2수평부(132-5)로 이루어진다.The shaft has a cross section from left to right, including one horizontal portion 132-1, a first slope portion 132-2, a gear portion 132-3, a second slope portion 132-4, and a second horizontal portion. (132-5).

상기 후방웜기어도 전방웜기어와 동일하게 형성된다.The rear worm gear is also formed in the same manner as the front worm gear.

상기 제1수평부에는 감속기의 좌측 내벽면에 결합될 수 있도록 베어링이 설치되는 베어링 설치홈부분이 형성되어 있다.The first horizontal portion is formed with a bearing installation groove portion in which the bearing is installed to be coupled to the left inner wall surface of the reducer.

제1경사부는 좌측에서 우측으로 갈수록 하향하게 형성되고, 제2경사부는 좌측에서 우측으로 갈수록 상향하게 형성된다. 이에, 웜기어의 기어부에 헬리컬기어가 접촉할 시, 웜기어의 제1경사부와 제2경사부에 의해 헬리컬기어의 헬리컬기어이빨이 웜기어의 축에 접촉하지 않게 설치되는 것이다.The first inclined portion is formed downward from the left to the right, and the second inclined portion is formed upward from the left to the right. Therefore, when the helical gear is in contact with the gear portion of the worm gear, the helical gear teeth of the helical gear are installed so as not to contact the shaft of the worm gear by the first inclined portion and the second inclined portion of the worm gear.

상기 제2수평부에는 감속기의 우측 내벽면에 결합될 수 있도록 베어링이 설치되는 베어링 설치홈부분이 형성되어 있다.The second horizontal portion is formed with a bearing installation groove portion in which the bearing is installed to be coupled to the right inner wall surface of the reducer.

그리고 상기 웜기어기어이빨의 일면에는 곡면돌출부가 형성된다.A curved protrusion is formed on one surface of the worm gear tooth.

The second inclined plane 121-3, the first horizontal plane 121-4 formed in the horizontal direction from the end of the second inclined plane, and the third inclined plane 121-5 downwardly downward from the end of the first horizontal plane. ), A fourth inclined surface 121-6 downwardly downward from the end of the third slope, and a second curved surface 121-7 formed at the end of the fourth slope.

상기 웜기어기어이빨은 축의 길이방향을 따라 외주연을 감싸며 나선형으로 형성되되, 웜기어기어이빨은 웜기어기어이빨의 일면을 따라 곡면돌출부가 형성된다. 상기 곡면돌출부는 기어결하보디는 헬리컬기어이빨의 제1곡면 또는 제2곡면에 접촉될 수 있도록 원호 형상으로 돌출형성된다. The worm gear teeth are spirally formed around the outer circumference along the longitudinal direction of the shaft, and the worm gear teeth are curved projections along one surface of the worm gear teeth. The curved protrusions are protruded in an arc shape so that the gear binding body can be in contact with the first curved surface or the second curved surface of the helical gear teeth.

이에, 상기 웜기어와 헬리컬기어가 기어결합시 접촉면이 많아져서 동력을 전달할 시 손실되는 동력을 줄일 수 있게 되는 것이다.Accordingly, the worm gear and the helical gear have a large contact surface when the gear is coupled, thereby reducing the power lost when transmitting power.

따라서 본 발명은 웜기어와 헬리컬기어를 결합하여 모터에 의해 전달되는 동력의 속도는 낮추며 토크를 올리되, 감속기를 거쳐 전달되는 동력의 손실이 줄어드는 현저한 효과가 있다.Therefore, the present invention combines the worm gear and the helical gear to increase the torque while lowering the speed of the power transmitted by the motor, and has a remarkable effect of reducing the loss of power transmitted through the reducer.
