Gear shaft
The processing sequence of the main surface of the gear shaft depends to a large extent on the selection of the positioning standard.The structural characteristics of the shaft part itself and the position accuracy requirements of the main surfaces of the spindle determine the axis as the positioning reference.In this way, while the reference is unified, the positioning reference and the design reference coincide.Generally speaking, the outer circle is the rough reference, and the tip holes at both ends of the shaft are usually used as the accuracy reference.
