Reducer principle

时间:2018-10-27 11:23   tags: Press Room  

        The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the original moving part and the working machine.It plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery.

        The reducer uses various levels of gear transmission to achieve the purpose of speed reduction. The reducer is composed of various levels of gear pairs. For example, a small gear can be used to drive a large gear to achieve a certain reduction. It can greatly reduce the speed and increase the torque.

        The principle of the reducer is explained in detail: when the output speed of the motor is input from the driving shaft, it drives the small gear to rotate, and the small gear drives the large gear to move, and the large gear has more teeth than the small gear, and the speed of the large gear is slower than that of the small gear. The shaft (output shaft) of the large gear is output, thereby decelerating the output.
Working principle of gear reducer
        The reducer is generally used for low-speed and high-torque transmission equipment. The power of the electric motor, internal combustion engine or other high-speed operation is achieved through the gear of the input shaft of the reducer with a small number of teeth meshing with the large gear on the output shaft to achieve the purpose of deceleration. The reducer will also have several pairs of gears with the same principle to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. (That is, "Reduce the speed, increase the torque, and reduce the inertia")

        The reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor (motor) to the required number of revolutions and obtain a larger torque.In the current mechanism used to transmit power and motion, the application range of the reducer is quite wide.
