Title:
TRANSMISSION MECHANISM FOR STEPPER ELECTRIC MOTOR, STEPPER ELECTRIC MOTOR, AND DRIVE MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/019645
Kind Code:
A1
Abstract:
Disclosed in the present invention is a transmission mechanism for a stepper electric motor; and further disclosed are a stepper electric motor having the transmission mechanism for a stepper electric motor, and a drive mechanism having the stepper electric motor. The transmission mechanism for a stepper electric motor comprises: an input shaft; an output shaft, which is provided with a plurality of grooves evenly distributed on a circumferential face of the output shaft; an output gear, which is mounted on the output shaft, wherein the output gear is provided with a plurality of bumps, and the bumps match the grooves; and several transmission gear sets, which are used for transmitting power and are connected to the input shaft and the output gear. By means of matching the grooves with the bumps, the output shaft and the output gear are combined more securely during a transmission process, without the occurrence of the phenomenon of the output gear disengaging from the output shaft or a tooth being broken, such that the stepper electric motor is more stable and durable.
