Planetary reducers are generally used in transmission equipment with low speed and high torque. It is a power transmission mechanism that reduces the number of revolutions of the motor to the required number of revolutions by means of the speed converter of the gear to obtain a larger torque. .
The role of the reducer:
1. Deceleration increases the output torque, and the torque output ratio should be multiplied by the motor output reduction ratio, but be careful not to exceed the rated torque of the reducer.
2. The rotational speed also reduces the inertia of the load to the square of the reduction ratio.
Reducer type and characteristics:
1. Worm gear reducer: It is characterized by the function of reverse self-locking, which can have a large reduction ratio, and the input shaft and output shaft are not on the same axis or plane.However, it is usually bulky, with low transmission efficiency and low precision.
2. Harmonic reducer: its characteristic is that the harmonic drive uses the controllable elastic deformation of the flexible element to transmit power, small in size and high in precision. The disadvantage is that the flexible wheel has limited life, poor impact resistance, and rigidity compared with metal parts. Difference.
3. Planetary reducer: It is characterized by compact structure, small return clearance, high precision, long service life, and large rated output torque.
