What Is Cycloid Pin Gear Reducer?
Overview and principle of cycloid pin gear reducer
Cycloidal pin gear reducer is a novel transmission device that applies the principle of planetary transmission and adopts the meshing of cycloidal pin teeth. The entire transmission device of the cycloidal pinwheel reducer can be divided into three parts: the input part, the deceleration part, and the output part.
Composition
The input shaft is equipped with a double eccentric sleeve displaced by 180°, and two roller bearings called swing arms are installed on the eccentric sleeve to form the H mechanism. The center holes of the two cycloids are the upper swing arm bearings of the eccentric sleeve. In order to reduce the friction, in a reducer with a small speed ratio , Needle tooth sleeve is attached to the needle tooth).
Principle
When the input shaft rotates one circle with the eccentric sleeve, 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.
