Abstract
The invention discloses a micro-motor rotating shaft, which includes a rotating shaft and an inner shaft; the rotating shaft body includes an input section, a connecting cylinder and a transmission section, and one end of the transmission section close to the connecting cylinder is provided with a circular accommodation hole and a square transmission hole, and the square transmission hole It communicates with the circular accommodation hole; the inner shaft is located in the connecting cylinder, the inner shaft includes a first end and a second end, the first end of the inner shaft is connected with the input section, the second end of the inner shaft is located in the circular accommodation hole, and the inner shaft The outer surface of the second end of the shaft is not in contact with the circular receiving hole, and the second end of the inner shaft is also provided with a transmission block, the transmission block is located in the square transmission hole, and there is a gap between the outer surface of the transmission block and the inner wall of the square transmission hole ; The input section, the connecting cylinder, the transmission section, the circular accommodating hole and the inner shaft are coaxial; there is a gap between the inner shaft and the connecting cylinder. The present invention is provided with two sets of torque transmission components, the inner shaft and the connecting cylinder, and the torque is transmitted by the inner shaft after the connecting cylinder breaks and fails, so as to avoid the complete interruption of power output.
