What is a减速机?

A reducer is a power transmission device that uses a speed converter, such as gears, to reduce the rotational speed of a motor to the desired speed and achieve a higher torque.

The Function of the Gearbox:

1) Reduce speed while increasing output torque; the torque output ratio is calculated by multiplying the motor output with the reduction ratio, but be mindful not to exceed the rated torque of the reducer.

2) The company has also reduced the load inertia, with the reduction in inertia being the square of the deceleration ratio. You can see that most motors have an inertia value.

Section 3: Types of Gearboxes:

Standard reducers include bevel gear reducers (such as parallel shaft bevel gear reducers, worm reducers, bevel gear reducers, etc.), planetary gear reducers, cycloidal pinion reducers, worm and worm gear reducers, planetary friction-type variable speed machines, and more.

1) The main features of the worm and worm gear reducer include reverse self-locking function, with a significant reduction ratio, and the input and output shafts are not aligned on the same axis or plane. However, they are generally larger in size, have lower transmission efficiency, and lower precision.

2) Harmonic drive's harmonic transmission utilizes the controllable elastic deformation of flexible elements to transmit motion and power. It has a compact size and high precision, but its drawbacks include a limited lifespan of the flexible ring, poor resistance to impact, and inferior rigidity compared to metallic components. The input speed should not be too high.

3) The planetary reducer boasts a compact structure, minimal return gap, high precision, long service life, and can achieve a high rated output torque.
