Resons of heating of rolling bearing and its elimination method
(1) reason: bearing precision is low
Methods: bearings with specified precision grade were selected.
(2) reason: the spindle is bent or the box body hole is different
Methods: repair main shaft or box.
(3) reason: the belt is too tight
Methods: adjust the belt to make it elastic properly.
(4) reason: poor lubrication
Methods: select the specified number of lubricants and proper cleaning.
(5) reason: low assembly quality
Methods: to improve assembly quality.
(6) reason: running ring of bearing inner shell
Methods: bearing replacement and related wear parts.
(7) reason: too much axial force
Methods: between 0.2mm and 0.3mm should be required for cleaning and adjusting the clearance of the sealing ring, and the diameter of the balance hole of the impeller and the static balance value should be corrected.
(8) bearing damage method:Replace the bearings.
