Structure of Cycloidalreducer,gearmotor

Cycloidal reducer or gearmotor is very widely used in machine industry.

It mainly include three parts: input part, speed reduction part and output part.

Each part also include many elements:

1.output shaft.

2.tight ring of output shaft.

3.small end cap.

4.engine base.

5.pin bush of pin roll.

6.cycloidal wheel.

7.eccentric bearing.

8.spacer ring.

9.set of pin gear.

10.shell of pin gear.

11.big end cap.

12.fan cover.

13.input shaft.

We can see there is no gear inside of the cycloidal reducer.

But in application that many people call it cyloidalgearmotor.

Because it is looks very similar with gearmotors and has similar applications.

So It is the "gearmotor" which does not have gear inside but cycloidal wheels.

Cycloidal wheels working as a planetary way.

This cycloidalgearmotor can give a very large ratio with a small size.

It also can well suffer a big loading in a short time to avoid broken from loading sudden changes.
