Abstract

A planetary gear transmission is provided. A planetary gear transmission device includes: a planetary gear device including a sun gear, a ring gear, a plurality of planetary gears, and a planet carrier; a motor for generating a rotational force input to the planetary gear device and including a motor shaft and a motor body; a fixing bracket formed to fix any one of a sun gear, a ring gear, or a planet carrier of the planetary gear device to prevent rotation; and a circulating rotation bracket provided with the motor and fixed to one of the parts of the planetary gear device that is not fixed by the fixing bracket, in which the motor body is rotated by the circulating rotation bracket when one of the parts of the planetary gear device that is connected to the motor shaft is rotated by the motor shaft, and the rotating force of the motor shaft is output through the circulating rotating bracket.

Description

technical field [0001] The present disclosure relates to a planetary gear transmission for transmitting power using the planetary gear and a robot having the planetary gear transmission. Background technique [0002] Generally, a planetary gear device is widely used as a transmission device. [0003] The planetary gear device includes a ring gear, a sun gear provided at the center of the ring gear, a plurality of planetary gears arranged between and engaged with the ring gear and the sun gear, and a carrier provided with the plurality of planetary gears. [0004] A planetary gear arrangement can transmit power in various ways. For example, in the case of using the sun gear as the input, when the planet carrier is fixed, the reverse deceleration output is achieved through the ring gear. Conversely, when the sun gear is used as input and the ring gear is fixed, the forward reduction output is achieved through the planet carrier. [0005] In addition, in the case of using th...
