gear shaft

Positioning base the choice of gear shaft on the surface of the main processing order, to a sizable extent depends on the selection of locating datum structure features and the primary shaft of the shaft parts upon the surface of the primary location accuracy requirement is decided the axis since planetary gearbox benchmark may be the ideal not just ensure that benchmark is unified, and make the locating datum and the design datum coincidence outdoors circle designed for crude benchmark additionally, upon both sides of a sharp hole for fine benchmark concrete also take note the following factors: (1) when the choice between machined surface when the position accuracy of high, greatest carried out in a clamping surface processing (2) for rough machining or when two end middle holes (such as spindle cone hole) cannot be used to get positioning, to improve the stiffness of the procedure system during workpiece processing, just cylindrical surface or cylindrical surface area and one end middle hole can be utilized as positioning reference
