[0043] For the initial position circumferential angle positioning method of the driving and driven shafts of the existing pulley spinning equipment, the transmission method of a gearbox cooperating with a spline shaft is usually adopted to achieve positioning. As shown in Figure 2, for the positioning method achieved by the transmission method of a gearbox cooperating with a spline shaft, the motor is connected to the main gearbox 01, and through the main gearbox

[0044] 01 for speed change and distribution, a part of the power of the motor 03 directly drives the driving shaft to rotate, and another part passes through

[0045] the spline shaft 04 to provide power for the secondary gearbox 02, and then the secondary gearbox 02 drives the driven shaft to rotate after speed change. The transmission component - the spline shaft is affected by the manufacturing precision of parts, resulting in insufficient initial position circumferential angle positioning precision of the driving and driven shafts.
