Cycloidal pinwheel reducer structure

The entire transmission device of the cycloid reducer can be divided into three parts: the input part, the deceleration part, and the output part.

A double eccentric sleeve with a dislocation of 180 is installed on the input shaft, and two roller bearings called rotating arms are installed on the eccentric sleeve to form an H mechanism and the center hole of the two cycloidal wheels is the bearing of the upper rotating arm of the eccentric sleeve. raceway, and the cycloidal wheel meshes with a group of annularly arranged needle teeth on the needle gear to form an internal meshing deceleration mechanism with a tooth difference of one tooth (in order to reduce friction, in a reducer with a small speed ratio, Needle tooth sleeves on the needle teeth).When the input shaft rotates with the eccentric sleeve for one week, due to the characteristics of the tooth profile curve on the cycloid wheel and its restriction by the needle teeth on the needle gear, the motion of the cycloid wheel becomes a plane motion with both revolution and rotation. When the input shaft rotates forwardly, the eccentric sleeve also rotates once, and the cycloid wheel rotates one tooth in the opposite direction to obtain deceleration. Then, with the help of the W output mechanism, the low-speed autorotation motion of the cycloid wheel is transmitted to the output shaft through the pin shaft. This results in a lower output speed.

Cycloidal pinwheel reducer structure description

The reducer can be assembled with the Y series special motor and the special motor derived from the Y series to form a direct-connected reducer, such as YB explosion-proof motor, YCT speed regulating motor, YEJ electromagnetic brake motor, YEZ cone rotor brake motor At the same time, it can be connected with various types of motors in the table, such as: NEMA series, IEC series, Y series, YA series, YB series, YE series, YCT series, YZ series, ZD series and other motors. , which constitutes the structure of the direct-connected cycloidal pinwheel reducer.
