Bearing calculation: torque hydrostatic bearing is what material

FC number of roller bearing with grain, grain, grain, when used in hot rolling mill radial clearance control mostly in group C offline, my personal opinion is have no direct relationship with the roller grain number of bearing burning, should search for bearing in the bearing on the processing quality more the cause of the loss. Can be said to be so far in terms of bearing wear ideal repair technology, the scene is glycerin lubrication, more clean, no oil accumulation, the more did not fire occur. Bearing under non rotational state, because carry significant vibration load or overload, the ball or roller in the roll channel of sexual light and smooth pit, such deformation - Are not allowed to exist. High temperature fan bearings wearing traditional repair method of repair welding and processing: thermal stress concentration, easy to cause the axial bending deformation or fracture, and for large axial or bearing housing repair, comprehensive cost is high, the repair cycle is long, the intensity of labor is big, the processing equipment demanding strict; At the same time can not be implemented online repair; Brush plating: demanding for driving part wear form, wear uniform, wear depth below. （ Figure before and after the repair steps on the basis of the wear section end unworn trunnion sizes processing standard split mold ( Reference to figure the mold should be made of thick wall steel pipe wall thickness should have sufficient strength and stiffness, ensure that won't produce deformation. Some motor factory in recent years on the adoption of two ball bearing pole motor using large clearance ball bearing, bearing heat makes it is ease for runtime clearance measures of reducing incur bearing damage. Needle roller bearing needle roller bearing: ( Stamping, thrust, needle roller and cage components) Due to compact structure, small radial size, large load capacity, especially suitable for the limited size of the radial installation supporting parts, accord with the requirement of mechanical equipment to small HuaQing quantitative development. And also to prevent metal corrosion protection, and the sealing dust. For the installation of spherical roller bearing axial clearance, available on the journal of adjusting nut, adjusting shim and bearing hole of the thread, or use the methods of preloaded spring to adjust. Too much problem of abnormal temperature rise of lubricant: reduce lubricant; Increases the lubricant is not enough, or is not suitable for lubricant and choose a suitable lubricant; Mating surface creep or sealing device is too big: bearing outside diameter or inner diameter with surface correction, sealing form changes. Hertzian contact stress & amp; emsp; & emsp; , the service life of the equipment operation will be damaged or achieve cycle, mining equipment is not exceptional also. With the operation and diffusion; Is always accompanied by vibration significantly increased; Reason: bearing expires in the calculation of fatigue life is still in use; Solution: replace the bearing and/or consider to redesign.
