Analysis on main causes of heating of ina universal joint bearing

  • The phenomenon that the size or shape of ina stainless steel bearing or component changes due to stress is called deformation. The mechanical equipment on the production site often overloads due to poor working conditions, and the deformation of some bearings is very common. 
  • Their deformation will accelerate the wear and even fracture of other relevant parts, and may also lead to the damage of system series bearings or the damage of the whole equipment, resulting in equipment accidents, so the harm of deformation is quite serious.Maintenance Countermeasures for deformation of ina stainless steel bearing

  • The deformation of ina stainless steel bearing when the action stress is less than the yield strength of the material is called elastic deformation. Plastic deformation, also known as permanent deformation, refers to the deformation of bearing parts that cannot be recovered after the external force (load) is removed. 
  • Excessive deformation is an important type of mechanical equipment failure.Maintenance Countermeasures for deformation of ina stainless steel bearing
  • 1. Use reasonable cooling methods:Maintenance Countermeasures for deformation of ina stainless steel bearing
  • The influence of cooling process on deformation after metal quenching is also a very important deformation reason. The deformation of hot oil quenching is smaller than that of cold oil quenching, which is generally controlled at 100 ± 20 ℃. The cooling capacity of oil is also crucial to deformation. 
  • The stirring mode and speed of quenching affect the deformation. The faster the cooling speed of metal heat treatment, the more uneven the cooling, the greater the stress, and the greater the shape of ina stainless steel bearing of the die.Analysis on main causes of heating of ina universal joint bearing
  • 2. Use appropriate media:Analysis on main causes of heating of ina universal joint bearing
  • On the premise of ensuring the same hardness requirements, try to use oily medium. Experiments and practice have proved that on the premise of no difference in other conditions, the cooling speed of oily medium is slower, while that of aqueous medium is relatively faster.Analysis on main causes of heating of ina universal joint bearing

  • After metal heat treatment, in the cooling process, the thin part always cools fast and the thick part cools slowly.Analysis on main causes of heating of ina universal joint bearing
  • The vibration measurement of ina stainless steel bearing shows that the damage of bearing vibration to bearing is very serious. Therefore, through the adoption of extraordinary bearing vibration measuring instrument (frequency analyzer, etc.), the magnitude of vibration can be measured, and the incomparable specific situation can be measured through frequency division. 
  • Because the measured values are different due to the service conditions of the bearing or the installation position of the sensor, it is necessary to analyze and compare the measured values of each machine in advance to determine the scale.Analysis on main causes of heating of ina universal joint bearing

  • Generally, the temperature of the British bearing starts to rise slowly with the operation of the bearing, and reaches a stable state after 1-2 hours. The normal temperature of fag bearing varies with the heat capacity, heat dissipation, speed and load of the machine.
  •  If the lubrication and installation are not appropriate, the bearing temperature will rise sharply and abnormal high temperature will occur. At this time, the operation must be stopped and necessary preventive measures must be taken.Analysis on main causes of heating of ina universal joint bearing
