Usually happen when the machine is running, is the phenomenon of overheating bearing is a headache for the reason of overheating, bearing a very DuoZhong, this time by subjective consciousness, dont tell, but should step by step check, suit the remedy to the case. The reason of overheating in bearing does not exclude the bearing of the problems in the machine itself. Sometimes the mechanical parts within the cause (such as component tolerance requirement has a problem, similar to the base, the spare parts such as cover, shaft coaxial tolerance is bad, etc), sometimes is bearing with inside and outside tight circle; Of course doesnt rule out the use of improper installation, such as motor shaft and asked to move the shaft of the device the coaxial tolerance of match requirements. Below are some of the more gave you the most common causes of bearing overheating phenomenon:
(1) bearing damaged, should be replaced immediately.
(2) bearing greases too little, too much or scrap iron impurity. The bearing capacity of the grease should not be more than 70% of the total volume, impurity should be replaced. Similar and bearing bad lubrication or bearings cleaning, there were no net grease sundry. Or it is bearing bad maintenance, cause bearing greases shortage or more than life, hair dry metamorphism.
(3) shaft bearing fits with tight or too loose. Too close to grinding, should be too loose with the axis should be to set.
(4) bearings and cover with tight or too loose. When tight processing bearings room, too loose ends in with steel set in.
(5) the two bearing assembly cover or cover bad. Will cover or bearing cover them into the mouth, with flat, tighten the screws up.
(6) belts tight or coupling assembly is poor. Belt tension adjustment, and the calibration coupling.
(7) bearing grease too little, impurity or oil ring stuck. Should be as refuelling, change new oil, repair or replace the oil rings.
