Definition of the Gear reducers

The gear reducer is a power transmission mechanism, the use of gear speed converter, the electric motor speeds will be reduced to the number of rotation to the number of rotation, and get a large torque.

The role of gear reducers:

1) reducing the speed at the same time to increase the output torque, torque ratio according to the motor output by the reduction ratio, but must pay attention to not exceed the rated torsion.

2) at the same time, the inertia of the load is reduced, and the inertia of the square is reduced. You can look at the general motors have an inertia value.

Type of Speed-reducers:

General reducers with helical gear reducer (including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducer, etc.), planetary gear reducer, reducer, worm gear, worm gear reducer, planetary friction type mechanical continuously variable transmission, etc..

1) the main characteristics of the worm gear reducer are with a reverse lock function, can have a larger reduction ratio, the input shaft and output shaft is not on the same axis, nor in the same plane. But the general volume is larger, the transmission efficiency is low, the accuracy is not high.

2) the advantages of planetary reducer are compact structure, small return space, nice precision, long service life, Large rated output torsion. But the price is a smaller expensive.
