Abstract

See full text

Proposed are 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 an input side, so as to be able to rotate and revolve and be disposed in n sets, and when fixing any one of a first sun gear and a second sun gear and switching one remaining sun gear into an input side and rotating the same, speed is not increased due to a self-locking function and a speed increase ratio is zero (a stationary state in which the sun gear used as the input side cannot rotate), thereby resulting in self-locking which is a non-operating state.
