Self-aligning roller bearing quality high temperature caused by the judge

In the process of assembly, can also check out the pros and cons of bearing material, so as to identify the merits of the bearing quality. After the bearing inner ring assembly on the shaft, under normal operating conditions, if the bearing material is unqualified, forced deformation due to the inner ring, change will cause stent deformation or clearance, so that the spherical roller bearing rotation is not flexible and rolling body fall off. In addition, bearing hardness value is 60 ~ 65 HRC, above or below this value are not qualified. When bearing hardness test, the side of the checkpoint persons inside or outside, in order to avoid damage to the bearings. Test, the available file at about 10 n ( Or use a hacksaw blade in the force of about 5 n) File ( Or saw) Bearing outer ring and inner ring, if the thrum 'luo, luo' without crumbs, leaving only not clear file ( Or saw) Mark is enough hardness, with the file ( Or saw) The material hardness of sawdust, explanation did not meet requirements. In addition, before the hardness tests, should negotiate with the supplier first, when the supplier said 'conform to the requirements of the standard hardness, as does not conform to the request or return' again. A, spherical roller bearing installation position is not correct, will cause a larger ball end face and inner race and bearing seat block of axial force, bearing caused by overheating. Second, the use of the bearing had better choose the accuracy grade of bearing. Bearing spindle bending or casing hole, one of the three, use of different heart fever caused by the solution is to repair the spindle four, bearing belt too tight to cause fever solution is make the elastic of the belt can be adjusted properly. Five, the fever caused by poor lubrication of the solution is to use the provisions, brand of lubricating materials and proper cleaning. Six, assembly quality low fever caused by the solution is to improve the quality of assembly. Seven, in the rolling bearing shell run laps cause fever solution is to replace the bearing and wear parts related correcting impeller balance hole diameter and checking static balance value eight, axial force is too large to cause fever solution is cleaning, adjusting seal mouth ring clearance requirement nine, rolling bearing damage caused by fever bearing solution is replaced. When we are in the use of spherical roller bearing, if it is found that the temperature is very high, is to stop the equipment running, and find out its reason, and provide solution for processing according to the above, but may be due to the reason of bearing heating is different, so the solution is also different, so still have to treat, particular case is particular completed with the help of the technical staff.
