Several aspects of influence bearing temperature

After bearing pressure into the bearing should be flexible rotation without block. If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade. Such as thrust cylindrical roller bearing pressure into the shaft by hand after the rotation has obvious 'sasha vujacic' feeling, may be the shaft or shaft roundness tolerance is too big. When control the shaft and the bearing chamber tolerance so also want to control the roundness, at present many domestic manufacturers to control the tolerance, not to control the roundness. Because the bearing is high precision products, such as improper assembly is easy to cause damage to bearing channel, result in bearing damage. Thrust cylindrical roller bearing in the assembly shall have a dedicated mold, not casually, only small circle of stress when pressure into the shaft, pressure can force the circle circle. Require the use of pneumatic or hydraulic assembly, lower die when being connected to outside the level state, if there are any tilt can lead to bearing channel due to mechanical damage, and make the bearing guide ring. 1. Bearing temperature rise should be how to deal with: when the bearing temperature, first determines whether the wrong operation, such as really rise, should do the following treatment: ( 1) 。 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. ( 2) 。 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. ( 3) 。 Check for different bearing, bearing and testing degrees whether there are abnormal. ( 4) 。 Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. ( 5) 。 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. First of all, let's take a look at the cause of the bearing temperature: ( 1) 。 May be bearing oil degradation, the oil itself is not clean or run medium oil degradation, such as moisture in the oil increase can cause the acidity of the oil, can reduce oil lubrication, the bearing shell was corrosion, cause temperature rise of bearing. ( 2) 。 May be because the bearing of the cooling water.
