Stainless steel bearing overheating problem to be handled

In the practical application of stainless steel bearings, believe a lot of people often stainless steel bearing heating problems, need to how to deal with? First of all need to understand the causes of stainless steel bearing heating. Stainless steel bearings work in more than normal temperature reason may be: 1, stainless steel bearings and shaft neck joint uneven or interface is too small ( Fit clearance is too small) , per unit area than the pressure is too large, most of this kind of circumstance happening after the new machine commissioning or a new bearing shell; 2, stainless steel bearing deflection or crankshaft bending, distortion; 3, bearing quality is bad, lubricating oil (quality discrepancy Low viscosity) , or oil block. Gear oil pump oil pressure is too low, and oil supply disruptions, the four short of oil, dry friction; 4, stainless steel bearings with sundry or lubricating oil too much, too dirty; 5, bearing excessive wear of uneven; 6, compressor installation spindle and motor ( Or diesel engine) Main shaft coupling no alignment, error is too big, caused two axis tilt. To know the cause of the stainless steel bearing heating, we can suit the remedy to the case. Elimination method: 1, with coloring method to grind bearing shell, make its surface meets the requirements, improve specific pressure per unit area; 2, adjust the tolerance clearance, check the crankshaft bending, distortion, depending on the situation in the new crankshaft or repair; 3, use conforms to the quality of bearing bush, check pipeline and gear oil pump, and use meet the requirements of the quality of lubricating oil, check the adjustment of oil pump to pressure requirements; 4, clean and replace the new oil, adjust oil pressure; 5, change a new bearing shell; 6, two machine concentricity is, leveling tolerance to meet the requirements of machine specification values. Especially in the compressor and motor connection with rigid connection, more attention should be paid to find.
