Document Type and Number:
WIPO Patent Application WO/2024/005397
Kind Code:
A1
Abstract:
The present invention relates to a swivel actuator capable of increasing fracture strength by increasing brake torque while minimizing backlash. The swivel actuator according to the present invention comprises: a driving motor having a rotor worm gear integrally formed on the outer periphery of a cylindrical rotor support; first and second gear trains, each being arranged at 180 degree intervals at the outer periphery of the rotor worm gear and being coupled thereto, having, in the middle of first and second power transmission shafts, first and second worm wheels gear-coupled to the rotor worm gear, and having first to fourth worm gears formed at both sides of each of the first and second power transmission shafts; first to fourth pinion gear units, each having, at the lower ends thereof, third to sixth worm wheels gear-coupled to the first to fourth worm gears, and having first to fourth pinion gears integrally formed at the upper ends thereof; and a rotary table gear-coupled to a ring gear having the first to fourth pinion gears integrally formed on the inner side of the side surface part thereof, so as to rotate.
