What are the reasons for the high temperature of the transmission shaft bearing


The high temperature of the bearing is a common and harmful fault of rotating equipment, which affects the service life of bearings and the operation of equipment. When the bearing temperature is too high, it is necessary to quickly determine the cause of the fault and take appropriate measures to solve it. What are the reasons why the temperature of the transmission shaft bearing is too high? Let's learn about it.

The reasons for the high temperature of transmission shaft bearing  may involve the following aspects:

1, the bearing is too tight (interference is too large).In this case, the smaller clearance will reduce the amount of lubricating oil in the bearing, and the heat generated by friction can not be taken away in time. At the same time, the excessive loss of shear friction of grease in the clearance will also cause bearing heating. Therefore, it is necessary to adjust the clearance and check the accuracy.


2, poor lubrication conditions or unreasonable selection of lubricants. Insufficient or excessive lubrication and improper selection of lubricants may increase bearing temperature. At the same time, lubricating grease mixing or contamination by impurities will also lead to the destruction of bearing lubrication and the rise of temperature.


3. The configuration form of the bearing itself and the structure of the spindle assembly is unreasonable. This problem belongs to the design itself and cannot be changed in the installation and adjustment process.


4, bearing abnormalities, such as rusting, wear, and bearing clearance is too large will also cause unstable rotor operation, leading to bearing vibration, heating.


5, the coupling alignment process does not meet the requirements, rotor dynamic, and static is imbalanced.


6, the impact of external environmental temperature. Bearings like those located near a heat source are more likely to heat up
