gear shaft

Positioning base the decision of gear shaft upon the surface of the primary processing planetary gearbox purchase, to a large extent depends on selecting locating datum structure characteristics and the main shaft of the shaft parts upon the surface of the primary location accuracy requirement is set the axis since benchmark is the ideal not only make sure that benchmark is unified, and make the locating datum and the look datum coincidence outdoors circle pertaining to crude benchmark more commonly, on both sides of a razor-sharp hole for fine benchmark concrete also notice the following points: (1) when the decision between machined surface area when the position accuracy of high, greatest performed in a clamping surface area processing (2) for rough machining or when two end center holes (such as spindle cone hole) cannot be used to get positioning, to improve the stiffness of the process program during workpiece processing, just cylindrical surface area or cylindrical surface and one end center hole can be utilized as positioning reference
