Installation methods shaft parts of the shaft parts are the following three. 1. Two-center hole location fixture generally cylindrical surface as an important benchmark crude positioning, processing center hole, then both ends of the center hole axis positioning accuracy benchmark; benchmark unified as possible, coincide reference each other benchmarks, and achieve install multiple surface machining. Center hole is uniform workpiece positioning reference and test benchmarks automotive shafts, it is very important to their quality, their preparation is relatively complex, often bearing journal positioning, vehicle (drill) central cone; then to the center hole location mechanical shaft parts, precision car cylindrical; outside the circle positioning shaft parts, coarse cone; shaft parts to repair center hole location, cylindrical grinding; and finally locating cylindrical bearing journal, grinding (scraping or grinding) cone, so the precision taper meet the requirements. Ends short taper and face short head cone C and D on the end face of the two spindle bearing journal A, B radial runout tolerance of 0.008mm; surface roughness Ra of 0.8mm. It is installed chuck positioning surface. To ensure the accuracy of centering chuck, the conical surface must be concentric bearing journal, and the end face must be perpendicular to the rotation center of the spindle. ⑷ empty empty sets of gear sets gear journal bearing journal journal of A, B radial runout tolerance of 0.015 mm. Since the journal is cooperating with the gear bore surface of the bearing journal should be a concentricity requirements, otherwise the spindle drive engagement bad, when the spindle speed is high, but also affect the smooth gear and noise .
