Characteristics and functions of reducers

Characteristic
The main feature of a worm gear reducer is its reverse self-locking function, which allows for a larger reduction ratio. The input shaft and output shaft are not on the same axis or plane. But generally, the volume is large, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of harmonic reducer utilizes the controllable elastic deformation of flexible components to transmit motion and power. It has a small volume and high accuracy, but the disadvantages are limited service life of the flexible wheel, lack of impact resistance, and poor rigidity compared to metal parts. The input speed cannot be too high. The advantages of planetary gearboxes are compact structure, small return clearance, high precision, long service life, and the ability to achieve a large rated output torque. But the price is slightly higher. Gear reducers have the characteristics of small size and high torque transmission. Gear reducers are designed and manufactured based on a modular combination system, with a wide range of motor combinations, installation forms, and structural schemes. The transmission ratio is finely graded to meet different operating conditions, achieving mechatronics integration. Gear reducers have high transmission efficiency, low energy consumption, and superior performance. Cycloid pinwheel reducer is a transmission model that adopts the principle of cycloidal pinwheel meshing planetary transmission. It is an ideal transmission device with many advantages, wide applications, and can operate in both forward and reverse directions.

Role
1. Reduce speed while increasing output torque. The torque output ratio should be calculated by multiplying the motor output by the reduction ratio, but it should be noted not to exceed the rated torque of the reducer.
2. Deceleration also reduces the inertia of the load, which is the square of the reduction ratio.
