Title:
CYCLOIDAL SPEED REDUCER
Document Type and Number:
WIPO Patent Application WO/2022/065584
Kind Code:
A1
Abstract:
The present invention relates to a cycloidal speed reducer. The cycloidal speed reducer according to the present invention comprises a reduction unit for decelerating an input torque, and an output unit for transmitting the decelerated torque to the outside. A cycloid rotor which is one component of the reduction unit has tooth protrusions formed thereon in an arc shape, and thus has an advantage of increasing productivity by lowering machining difficulty compared to the existing cycloidal tooth protrusions. In addition, rotor pins are accommodated in through holes formed at equal intervals in the cycloid rotor, and a bushing which fills the gap between the through holes and the rotor pins is formed in order to stably transmit the rotational force of the rotor pins, thereby achieving the effect of effectively distributing the load and transmitting the deceleration torque to the outside.
