What are the types and functions of common reducers.According to the needs of the reducer, different types of reducers should be selected.According to the different characteristics of the reducer, it can be divided into different types of reducer.Common reducers include worm gear reducers; planetary reducers; harmonic reducers.
1. Common types of reducers
(1) The harmonic drive of the harmonic reducer uses the controllable elastic deformation of the flexible element to transmit motion and power.Small size and high precision, but the disadvantage is that the flexible spline has limited service life, is not resistant to impact, and has poor rigidity compared with metal parts.The input speed cannot be too high.
(2) The planetary reducer has compact structure, small return clearance, high precision, long service life and large rated output torque.But the price is slightly expensive.
(3) The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio.The input shaft and output shaft are not on the same axis or plane.However, the volume is generally large, the transmission efficiency is not high, and the accuracy is not high.
2. The role of the reducer
(1) At the same time, the speed reduces the inertia of the load, which is the square of the reduction ratio.It can be seen that the general motor has an inertia value.
(2) Reduce the speed and increase the output torque at the same time.The torque output ratio is multiplied by the motor output multiplied by the reduction ratio, but be careful not to exceed the rated torque of the reducer.
3. Type of reducer
General reducers include helical gear reducers, including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc., planetary gear reducers, cycloidal pin wheel reducers, worm gear reducers, and planetary friction mechanical stepless speed changers. wait.
The reducer is generally used for transmission equipment with low speed and high torque.The electric motor, internal combustion engine or other high-speed power meshes with the large gear on the output shaft through the gear with a small number of teeth on the input shaft of the reducer.Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect.The gear ratio of the large and small gears is the transmission ratio.
