The installation of the bearings and remove the standard

A, application installed bearing common tools for dismantling the outstanding specialized tools, can prevent the installation time because of the special tools and poor practical bearing damage. When installing bearing, for example, that guy who choose copper rod type method, easy cause bearing radial tolerance not divide evenly, cause deformation of bearing, rolling body injury, lateral clearance increases, and the copper bar in the tapping process, at the end of copper into bearing, easy to cause the common faults of the bearing. Bearing 2, before the installation to prepare the inspection work in view of the old bearings, need to check the steel ball, Column) If surface have burrs, scratch, crack. Old bearing radial clearance, the radial clearance is up to standard, generally only accurately measure the radial gap. For new bearing, the first to check the bearing type specification is appropriate. 3, check the bearing degree of mutual cooperation and motor rotor shaft motor assembled, need careful bearing installation bearing degree of mutual cooperation and motor rotor shaft, bearing the lateral and bearing end cover hole degree of mutual cooperation. Four, control the volume of oil bearing and bearing indoor bearing and residual oil box is overmuch, can cause bearing roller running deviation, lead to roll body from rolling friction to rolling friction, the destruction of rolling element bearings, because bearing too much residual oil, bearing box in free space is little, operation of the bearing temperature rise, reduce grease hz degree, rolling body soften grease film, RunHua standard deviation, easily lead to bearing ring, surface smooth, reduce the service life of bearing. , in view of the bearing of the operation of the high temperature and high speed rotation should avoid as far as possible with the bearing, improve electricity oil cover stock remaining oil, and put to the nozzle, can promote the service life of the motor bearing operation. Five, pay attention to ensure insulation layer is in good condition for the lateral insulation design of bearing, pay special attention to ensure that the insulation is in good condition. When installation if damaged bearing insulation layer, the bearing oil is too thin will be shaft working voltage penetration, oil penetrate, not only make the roller RunHua standard extreme, in addition may spark discharge caused by the rolling element bearing electric erosion, the surface not only of the rolling element, accelerate the damage of the bearing. Above is today the author brought to you, want to learn more bearing small knowledge, pay attention to the bearing's official website.
