The assembly sequence of the parts on the shaft 2 is from left to right, the left end of the peeling roller is the bearing, the gear 6 is the gear 3 the gear 2, and the right is equipped with the peeling device and the bearing end cover. Therefore, a stepped shaft is used to avoid damage to the surface of the workpiece during installation. According to the gear manual, the diameter of the wheel hole must be greater than 20. Because the stepped shaft is selected, the length of the journal varies from 32, 35, and 40. Since the journal length is 40 the longest, only need to check the position. The design of the shaft is shown in the parts drawing.
