Document Type and Number:
WIPO Patent Application WO/2023/054900
Kind Code:
A1
Abstract:
A decelerator according to the present invention comprises: a decelerating portion for decelerating an input torque; and an output portion which receives a deceleration torque, set in advance, through the decelerating portion and transfers an output torque to the outside, wherein the decelerating portion comprises: an input shaft receiving the input torque; a cycloid disc having teeth formed along the circumference of the edge, and arranged on the outer circumferential surface of the input shaft to be eccentrically rotatable; a hollow-shaped housing in which the cycloid disc is accommodated, and which includes a plurality of inner pins arranged along the inner circumference of the housing at certain intervals so as to come into contact with the teeth of the cycloid disc; and a plurality of rolling pins which are coupled to the cycloid disc and have concentric cylindrical structures. The output portion comprises an output rotor which accommodates the rolling pins and transfers the deceleration torque transferred from the rolling pins to the outside. In addition, the rolling pins may eccentrically move relative to the output rotor.
