Title:
SPEED REDUCER HAVING SELF-LOCKING FUNCTION WITHOUT RING GEAR, AND SELF-LOCKING METHOD OF SPEED REDUCER
Document Type and Number:
WIPO Patent Application WO/2022/245143
Kind Code:
A1
Abstract:
The present invention relates to a speed reducer having a self-locking function without a ring gear, and a self-locking method of the speed reducer. Particularly, the speed reducer is characterized in that: first, second and third planetary gears are supported at different locations on one side of a carrier which is the input side, so as to be able to rotate and revolve and be disposed in n sets; and, by fixing any one of a first sun gear and a second sun gear and switching the other sun gear into an input shaft and rotating same, the speed is not increased due to a self-locking function and the speed increase rate becomes zero (a stopped state in which a sun gear used as an input cannot rotate), thereby resulting in self-locking which is a non-operating state.
