Bearing heat caused by improper lubrication
1.There are inherent deficiencies in the design of bearing lubrication parts
2.The lubricating oil pipe is blocked by foreign bodies
3.lubricating oil (fat) deterioration or refueling is not timely
Bearing heat due to improper installation
1. Bearing heat caused by insufficient design expansion
2. Bearing heat caused by installation skew
3. Heat caused by improper assembly of the bearing itself
Rotor unbalance
Some rotors wear during operation, or if the shaft is bent, it will lead to unbalanced centrifugal force, which causes the bearing to heat, vibration, and serious raceway wear until it is destroyed.
Check the replacement is not timely
Bearings such as serious fatigue spalling, oxidation rust, wear pits, cracks, should be replaced in time. If the inspection and replacement are not timely, it will cause the bearing to appear heat, noise, vibration and other conditions
Improper bearing selection
When selecting bearings, attention should be paid to the limit speed and load capacity of the bearing, and the speed and overload can not be used.
