About the structural characteristics of cycloid reducer products

The entire transmission device of the cycloid reducer can be divided into three parts: the input part, the deceleration part, and the output part.The cycloid reducer is equipped with a double eccentric sleeve with a dislocation of 180 on the input shaft, and two roller bearings called rotating arms are installed on the eccentric sleeve to form the H mechanism and the center hole of the two cycloid wheels is the eccentric sleeve. The raceway of the swivel arm bearing is meshed with a set of annularly arranged needle teeth on the needle gear by the cycloidal wheel to form an internal meshing deceleration mechanism with a tooth difference of one tooth (in order to reduce friction, when the speed ratio is small In the reducer, there is a pin tooth sleeve on the pin tooth).When the input shaft rotates once with the eccentric sleeve, due to the characteristics of the tooth profile curve on the cycloid gear and the limitation of the needle teeth on the needle gear, the movement of the cycloid gear of the cycloid reducer becomes both revolution and rotation. plane movement.
