Document Type and Number:
WIPO Patent Application WO/2023/191391
Kind Code:
A1
Abstract:
The present invention relates to an internal hollow swivel actuator including a cycloid reducer which can not only secure a large reduction ratio but also guarantee durability and quietness. A swivel actuator according to the present invention comprises: a housing having an open upper portion and including a cylindrical portion having a through hole formed in the center thereof; a drive motor disposed in the housing and having a worm gear integrally formed on an outer circumference of an extension portion extending from a rotary shaft; a worm wheel in which a gear coupled to the worm gear is formed on a cylindrical circumference thereof to generate primary reduced rotational power; and a cycloid reducer installed on an upper portion of the housing to receive the primary reduced rotational power of the worm wheel coupled to an input shaft, secondarily decelerate, and output the reduced output to a rotation table, wherein the cycloid reducer has a two-stage structure eccentric portion on the input shaft, and a two-stage external gear is coupled to an inner circumference of an internal gear.
