Title:
TRANSMISSION CONNECTED TO SERVO MOTOR AND POWER UNIT HAVING SERVO MOTOR AND TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2018/164334
Kind Code:
A1
Abstract:
According to the present invention, a transmission comprises: a driving shaft connected to a servo motor; a planetary gear part connected to the driving shaft; a shift gear part for allowing a gear-shifting operation to be performed in a state in which the driving shaft and the planetary gear part are simultaneously positioned at a set gear-shifting position when an operation for gear-shifting is performed while the servo motor stops; and an actuator for operating the shift gear part. According to the present invention, the transmission precisely controls an operation by using the servo motor, enables a high-output operation through gear-shifting as necessary, and can prevent malfunction and position deviation of a device during the gear-shifting operation, thereby improving operational stability and efficiency of other industrial automated devices, using the servo motor, such as a robot driving pack, a motor cylinder, a servo press, and a nut runner.
