Cycloid gearbox - a mechanism with a fixed gear ratio.
It lowers the speed.
The cycloidal gearbox is compact and has a high gear ratio.
The transmission shaft rotates the eccentric shaft with the pins, which gives the cycloid plate the movement of the eccentric.
In the circumference of the circle there are round holes on the outside.
In these holes insert the rods or rollers located to the lower attached disc.
With the help of rods and disks, rotational motion is transmitted to the shaft, but the radial displacement of the cycloid plate on the output shaft is not transmitted.
