[0002] The spinning frame is a spinning machine that stretches, twists and winds semi-finished roving or slivers into spun yarn tubes during the spinning process. It is the main machine for spinning, and usually includes a working part and a power part. The power part usually adopts a gear box (locomotive) with an electronic control function, and a motor is arranged at the bottom of the gear box (locomotive) to drive the main shaft of the working part to rotate and complete the spinning work. As for the arrangement of the motor, the end of the main shaft is usually extended into the gear box (locomotive), and a belt is arranged between the end of the main shaft and the output end of the motor to drive the main shaft to rotate. However, this arrangement method is very easy to produce flower accumulation on the main shaft in the gear box (locomotive) and the output shaft position of the motor, that is, the entanglement of the spinning fibers, which requires regular cleaning, and the cleaning cycle is short. At the same time, the main shaft is driven by the belt.
