Description

모터의 가감속 속도 조절장치{Increase and decrease velocity control apparatus of motor}Acceleration and deceleration speed control apparatus of motor

본 발명은 모터 2개의 속도차 또는 속도합을 이용하여 다양한 작업속도에 맞추어 가감속으로 조절가능함에 따라 정밀한 저속이나 고속 속도가 요구되는 설비에 설치되는 모터의 가감속 속도 조절장치에 관한 것이다.The present invention relates to an acceleration / deceleration speed control device for a motor installed in a facility requiring precise low speed or high speed as it can be adjusted to acceleration / deceleration according to various working speeds by using a speed difference or speed sum of two motors.

통상적 모터(Motor)는 전기 에너지를 기계적인 에너지로 바꾸는 장치로서, 대부분의 모터는 회전운동의 동력을 생산한다.A conventional motor is a device that converts electrical energy into mechanical energy, and most motors produce power of rotational motion.

이러한 모터 중 회전운동을 생산하는 모터를 이용하여 회전운동을 전달하는 설비는 모터의 구동축에 감속기를 설치하고 이 감속기가 벨트 내지는 체인과 같은 동력전달 수단으로 이용하여 피동축을 회전시키도록 되어 있다.A facility for transmitting a rotational motion using a motor that produces a rotational motion among these motors is to install a speed reducer on the drive shaft of the motor and rotate the driven shaft by using the speed reducer as a power transmission means such as a belt or a chain.

그러나 모터 1개와 감속기를 이용하여 정밀한 속도조절을 유지하면서 매우 느린 저속과 빠른 고속상태를 구현하기가 곤란하였다.However, it was difficult to realize very slow low speed and high speed while maintaining precise speed control using one motor and a speed reducer.

예를 들어, 타이어 제조시 성형공정에서 벨트드럼 드라이브의 경우 벨트와 트레드를 드럼 위에 감을 때 매우 정밀한 저속이 필요하고 JLB(Joint Less Belt)를 감을 때에는 고속으로 드럼을 회전시켜야 작업시간이 단축되는데, 1개의 모터와 감 속기를 이용하여 드럼 드라이브를 회전시킬 때 저속에서 정밀하게 회전하도록 설정한 후 고속에서는 모터의 최고속도 한계에 따라 JLB 작업속도를 맞추어 사용하였다.For example, in the manufacturing process of tire manufacturing, the belt drum drive requires very precise low speed when the belt and tread are wound on the drum. When rotating the drum drive by using one motor and a reducer, it was set to rotate precisely at low speed. At high speed, the JLB working speed was adjusted according to the maximum speed limit of the motor.

그러나 종래 이 같은 모터의 속도 조절장치는 작업속도에 맞추어 속도조절 작업을 할 때 1개의 모터와 감속기를 이용하여 속도의 정밀한 가감속 구현에 적당하지 않아 작업속도가 떨어지는 단점을 지니고 있었다.However, the conventional speed control device of such a motor has a disadvantage in that the work speed is lowered because it is not suitable for realizing precise acceleration and deceleration of speed using one motor and a speed reducer when adjusting the speed according to the work speed.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 제안된 것으로, 정밀한 저속과 고속의 속도들이 요구될 때 2개의 모터들을 이용하여 이들 모터들의 속도차 또는 속도합을 활용하여 저속과 고속의 작업속도 조절이 가능함에 따라 작업속도의 변경이 자유롭고 작업속도도 향상시킬 수 있는 모터의 가감속 속도 조절장치를 제공함에 그 목적이 있다.Therefore, the present invention has been proposed in view of the above-described conventional problems, and when the low speed and high speed of the precise speed are required, the speed of the low speed and high speed is controlled by utilizing the speed difference or the sum of the speeds of these motors by using two motors. The purpose of this is to provide an acceleration / deceleration speed control device of the motor that can change the working speed freely and improve the working speed.

상기와 같은 목적을 달성하기 위한 본 발명은 모터의 구동축에 감속기가 연결되고 이 감속기의 구동이 벨트를 통하여 피동축에 전달되어 상기 피동축의 속도를 조절하는 모터의 가감속 속도 조절장치에 있어서, 상기 모터의 구동축에 연결되는 감속기의 다른 반대쪽에는 직렬대향 모터의 구동축이 연결되고, 이 감속기의 하우징은 감속기의 구동력을 전달받아 회전하여 벨트를 통하여 피동축에 동력을 전달하는 구조로 되어 있다.In the present invention for achieving the above object is a reduction gear is connected to the drive shaft of the motor and the drive of the reducer is transmitted to the driven shaft through a belt in the acceleration and deceleration speed control device for controlling the speed of the driven shaft, The other side of the reducer connected to the drive shaft of the motor is connected to the drive shaft of the series opposing motor, the housing of the reducer is configured to rotate to receive the driving force of the reducer to transmit power to the driven shaft through the belt.

상기와 같은 본 발명에 따른 모터의 가감속 속도 조절장치는 2개 모터의 속도차 또는 속도합을 이용하여 다양한 작업속도 조절이 가능할 뿐만 아니라, 고속 작업시 작업시간 단축으로 생산성 향상에도 기여하는 잇점을 갖는다.Acceleration and deceleration speed control apparatus of the motor according to the present invention as described above is not only possible to adjust the various working speed by using the speed difference or the sum of the speed of the two motors, it also has the advantage of contributing to productivity improvement by shortening the working time at high speed work Have

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The housing 8 is rotated and power is transmitted to the driven shaft 7 via a belt 4 with the housing 8 mounted on its outer circumference.

이와 같은 구조를 갖는 본 발명은 2개의 모터, 즉 모터(1)와 직렬대향 모터(6)의 속도차 또는 속도합을 이용하게 되는데, 저속이 요구되는 경우, 상기 모터(1)의 구동축(2)이 시계방향으로 회전하면 직력대향 모터(6)의 구동축(7)은 반시계 방향으로 회전시키어 이들의 속도차를 이용하여 정밀한 저속을 감속기(3)의 하 우징(8)을 통하여 피동축(5)에 전달하게 된다.The present invention having such a structure uses a speed difference or a sum of speeds of two motors, that is, the motor 1 and the series facing motor 6, and when a low speed is required, the drive shaft 2 of the motor 1 ) Rotates clockwise, the drive shaft 7 of the linearly opposed motor 6 rotates counterclockwise and uses the speed difference to precisely rotate the drive shaft through the housing 8 of the reducer 3. 5) will be delivered.

한편, 고속이 요구되는 경우, 상기 모터(1)의 구동축(2)이 시계방향이면, 직렬대향 모터(6)의 구동축(7)도 시계방향으로 회전시키어 이들의 속도합을 이용하여 보다 큰 고속을 감속기(3)의 하우징(8)을 통하여 피동축(5)으로 전달한다.On the other hand, when a high speed is required, if the drive shaft 2 of the motor 1 is clockwise, the drive shaft 7 of the series facing motor 6 is also rotated clockwise to obtain a larger high speed using the sum of these speeds. Is transmitted to the driven shaft (5) via the housing (8) of the reducer (3).
