Hubei wuhan one bearing manufacturer faces many problems

Hubei wuhan one bearing manufacturer faces many problems look at the common problems when bearing assembly 1, hot charging of preparation before assembly parts fit size, root diameter, convex platform, round, and chamfering etc to review and correct, cooperate to disposal and clean appearance. High temperature bearing with key parts of flat key to advance according to the shaft and hole keyway and replacement and fixed onto the shaft. On inclined or tangential keys to apply direction key in order to ensure the keyway position to each other. Before the hot charging will ring, gaskets and other parts and replacement and fitting correct, calibrated after assembly. Hot charging before looking for is, at the same time be scribed line marks and direction indicator. Assembly appearance smooth coated with oil, in order to reduce the frictional resistance when loading. Hot charging before manufacturing measurement ruler to measure and confirm the heating workpiece can be heated to assembly conditions, the conditions for adopting the bulky and not easy to deformation ruler to meet, in the far away from heat source accurately measured the thermal condition of parts being tested. A ruler can be made of metal or metal plate, practice size measured parts shall be equal to the diameter of the nominal size plus cooperate in interference and assembling the necessary clearance. After heat through heating parts, measuring ruler can ease after, and confirmed by the recheck measured results are accurate, talents stop heating, stop hot assembly operations. 2, hot charging equipment to eliminate axial clearance after the hot charging, because often the result of the cooling contraction in the wheel and the shaft axial positioning shoulder place to present the axial clearance, nature is not in place, assembly location unstable phenomenon. Thus to bridge gaps in hot charging. Ordinary method, bolt tensioning method, adopting a collision weight method.
