CorrectReducerAnyone who knows or often contacts the reducer knows that the reducer is a power transmission device, which mainly uses the speed converter of the reducer gear to reduce the number of revolutions of the motor to the required number of revolutions and obtain a larger torque. The common types and functions of reducers are shared with you as follows.
1. Types of common reducers: general reducers include helical gear reducers, planetary gear reducers, cycloidal pinwheel reducers, worm gear reducers, planetary friction type mechanical continuously variable transmissions and so on.The main feature of the worm gear reducer is that it has a reverse self-locking function, which can have a larger reduction ratio, and the input shaft and output shaft are not on the same axis or on the same plane.However, the volume is generally large, the transmission efficiency is not high, and the precision is not high.The harmonic drive of the harmonic reducer uses the controllable elastic deformation of the flexible element to transmit motion and power. It is not large in size and has high precision, but the disadvantage is that the life of the flexible wheel is limited, it is not impact-resistant, and its rigidity is compared with metal parts. Difference.The input speed should not be too high.The advantages of planetary reducer are that the structure is relatively compact, the return clearance is small, the precision is high, the service life is very long, and the rated output torque can be very large.But the price is slightly more expensive.
2. The role of the reducer: reduce the speed and increase the output torque at the same time. The torque output ratio is multiplied by the stepper motor output by the reduction ratio, but it should be noted that the rated torque of the reducer cannot be exceeded.At the same time, the inertia of the load is reduced, and the reduction of inertia is the square of the reduction ratio.You can see that the general motor has an inertia value.
due toReducerGenerally used for low-speed and high-torque transmission equipment, the power of the motor, internal combustion engine or other high-speed operation is achieved by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft to achieve the purpose of deceleration. There will also be several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
