Timken cylindrical roller bearing temperature phenomenon of late damage forms

When the temperature rise of cylindrical roller bearing, first to determine whether there is an error action, if the temperature is indeed rising, should immediately do the following treatment: ( 1) , check the cooling water pressure, water flow and pipeline system is normal. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. ( 2) Low, should be to check if the governor oil pressure, oil pressure may lead to water hydraulic valve closed. ( 3) , check the timken bearings for different sounds and detection of cylindrical roller bearing degrees whether there are abnormal. ( 4) , take oil whether there is a change of color, sample observation and test to see whether metamorphism. If confirm the degradation new oil should be replaced downtime. ( 5) , check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing. Production equipment using the timken bearing operation performance loss in not form the accident: ( 1) Bearing inside or outside surface rotation skid slight traces. ( 2) Bearing surface and working surface corrosion. ( 3) Bearing inside diameter, outside diameter, raceway and rolling body surface is scratch or indentation. ( 4) Friction roller end face and guard surface adhesion. ( 5) Bearing working surface has slight wear. Use of timken bearing operation after the failure of damage of accidental damage state of performance: ( 1) Maintains a distort deformation or fracture. ( 2) Rolling body fracture. ( 3) Work surface fatigue peeling load bearing area. ( 4) Bearing inner and outer ring axial cracking or fracture. ( 5) Bearing outer ring radial crack or rupture or out side. ( 6) Bearing inner and outer ring, roller deformation, raceway formation pressure.
