Description

TECHNICAL FIELD

[0002] The starting motor driving assembly is mainly composed of a rotor, a one-way device, a ring, a circlip, a gear shaft, a driving gear and the like. A circlip groove is formed on the gear shaft near the end thereof, and the circlip must be accurately positioned in the circlip groove, and then the ring is pressed on the circlip so that the circlip is pressed into the ring groove of the ring, thereby axially positioning the driving gear and the ring through the circlip. The axial positioning of the circlip and the ring must be accurate, and if the error is large, the ring may not be press -fitted in place, the driving gear may be out of the gear shaft, and the starting motor may be disabled, and the transmission case may be damaged. Therefore, the assembly of the circlip and the ring plays a crucial role.
