Bearing machine: the reasons of high bearing temperature of air preheater

Shaft repair, spline, slotting, thread repair available gas welding or surfacing welding method to repair worn tooth profile, then on the basis of the wear and tear of the spline, milling spline. Applicable: oil cup drip lubrication is suitable for low speed and light load at a lower temperature, oil bath, Oiled) Lubrication, lubrication, but oil is not easy to adjust, no filter easy to impurities in the fuel tank into the bearing internal damage to the bearings. Detection methods and the selection of measuring benchmark position of the shaft coupling axis position deviation is certain benchmark position is very important, such as centrifugal horizontal pump unit, fan without growth, such as equipment, benchmark area should choose the motor end; With growth, with a coupler large blower, turbine, steam turbine, the benchmark parts should consider motor side in the adjustment of cumulative error produced in the process of value, at the same time also need to consider the influence of thermal expansion of shaft center, the choice of benchmark parts should try to meet the long operation period, standard parts, and thermal expansion centerline offset small parts as a benchmark. Because of the screw in the process of work mainly bear axial force, the size of the axial force and axial stiffness of ball screw, the repeat precision of the leadscrew, there are many factors that can affect screw axial stiffness, mainly includes: the axial stiffness of screw, the screw axial stiffness of supporting bearing and axial stiffness of ball nut, screw and the axial stiffness of the bearing, etc. Bearings rolling bearing general, closed type bearing cappedbearin - Methyl amino acetonitrile g with one or two seals, one or two dust cover and a sealing ring and a dust cover of the rolling bearing. LP— — Light metal entity type cage window, reducer bearing by additional load, bearing axial awful a tight, may also be fixed with two end bearing on the shaft. Diagram is painted yellow horns bearing, it is to cooperate in the horns, on the other end connected to the wheels, as long as the wheel rotation, the bearing will turn, so its bad working environment, damage is also understandable. Wire should be smooth and uniform, the size of the unfavorable impact, self-priming pump which require the use of oil pressure or pressure stable tension or can use tools, it had to use hammer, also want to through soft without exfoliation metals such as copper sleeve to buffer, tapping force as gently as possible. Water pump can't start the common cause of: packing too tightly or between the impeller and the pump body is sundry pile up and jam; Pump shaft, bearings, minus leakage ring rust to live; Pump shaft severe bending, etc. Concentric shaft and motor, switched on, the words of the precision screwdriver, in the C ring gap, to pry up the C ring, then side cover off, as long as the down side. This should not be subject to pure axial load bearing, installation position and adjacent parts even if the axis of rotation is vertical or inclined, lubricant and must be kept in the lubrication points. NSK bearings in theory when zero clearance noise and have reached the state of beautiful life, but in actual operation considering the problems such as temperature, NSK bearing clearance for after assembly.
