Reducer is a power transmission mechanism, the use of gear speed converter, the number of motor rotation to reduce the number of rotation, and get a larger torque mechanism.

The function of the reducer

1 reduce the output torque at the same time, torque output proportional to the motor output by the deceleration ratio, Reducer but pay attention to can not exceed the rated torque reducer.

2 speed reduces the inertia of the load at the same time, and the inertia is reduced to the square of the deceleration ratio. You can look at the general motor has a value of inertia.

Type of reducer

The general Reducer has helical gear reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloid reducer, worm gear reducer, Reducer planetary friction mechanical stepless speed-changing machine and so on.

The reducer is the key component of the robot, which accounts for One-third of the production cost of the whole robot. China's research on the robot reducer is late, the technology is not mature, the current serious dependence on imports, reducer is the key factor restricting the development of China's robotics industry, Reducer the overcoming of the reducer technology is the inevitable choice of domestic robot enterprise industrialization.

The main characteristic of the reducer is the reverse self-locking function, which can have a larger deceleration ratio, the input shaft and the output axis are not on the same axis and not on the same plane. Reducer But the general volume is larger, the transmission efficiency is not high, the precision is not high.

The harmonic transmission of the reducer is to transmit the motion and the power by using the controllable elastic deformation of the flexible element, Reducer the volume is small and the precision is very high.
