gear shaft

Positioning base the choice of gear shaft on the surface of the main processing purchase, to a sizable extent depends on the selection of locating datum structure features and the main shaft of the shaft parts upon the surface of the main location accuracy necessity is set the axis as benchmark is the ideal not only make sure that benchmark is unified, and make the locating datum and the look datum coincidence outdoors circle planetary gearbox pertaining to crude benchmark additionally, on both sides of a sharp hole for good benchmark concrete also take note the following factors: (1) when the choice between machined surface area when the positioning accuracy of high, greatest carried out in a clamping surface area processing (2) for tough machining or when two end center holes (such as for example spindle cone hole) can’t be used pertaining to positioning, to enhance the stiffness of the procedure program during workpiece processing, just cylindrical surface or cylindrical surface area and one end middle hole can be used as positioning reference
