The principle of cycloid reducer

When the input shaft rotates with the eccentric sleeve for one cycle, due to the characteristics of the upper tooth profile curve of the cycloidal wheel and the limitation of the needle gear on the needle gear, the motion of the cycloidal wheel becomes a plane motion with both revolution and rotation. When the input shaft rotates in the forward direction, the eccentric sleeve also rotates once, and the cycloidal wheel rotates one tooth in the opposite direction to obtain deceleration. Then, with the help of the W output mechanism, the low-speed rotation motion of the cycloidal wheel is transmitted to the output shaft through the pin shaft. In order to obtain a lower output speed.
