Angular contact ball bearing temperature processing method

For all kinds of imported bearings, play a role of the use to a greater extent and can prolong the service life, is not impossible. That will need to pay attention to in the process of use at ordinary times many small details, avoid the loss caused by improper use. TIMKEN bearing is no exception. With all of you here today is about TIMKEN bearing clearance hours prone to problems, please pay more attention in the use process in the future. When the TIMKEN bearing clearance through the hours, fever is the most prone to the condition of the bearing, and if the speed faster, it is possible to mana burn. And if no heed to continue for a long time under the environment of high temperature and high speed operation, will most likely hold TIMKEN bearing the phenomenon of death, and will produce the TIMKEN bearing supporting shaft or housing damage of bearing a hamstring strain. Angular contact ball bearing temperature, generally have a bearing on the surface of the outdoor temperature can be predicted, if use import bearing outer ring oil hole can directly measure temperature, is more appropriate. Generally, the temperature of the bearings with bearing operation began to slowly rise, 1 - After 2 hours to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor the working temperature of angular contact ball bearing, and implement e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. With high temperature often said bearing is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes bearing overheating can be classified to the TIMKEN bearing lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, bearing damage, clearance, high friction and oil seal and so on. So the continuity of bearing temperature monitoring is necessary, bearing whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. Regular bearing temperature measurement by using a thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of bearing, means that when the damage cause of equipment downtime, so this type of bearings shall be equipped with best temperature probe. In just under normal circumstances, bearing lubrication or lubrication after there will be a natural temperature rise and the last one to two days. Usually, the working temperature over 150 ° called high temperature bearing, angular contact ball bearing used due to chromium bearing steel in the use of temperature over 150 °, the hardness will fell sharply, size is not stable, the bearing can't work normally. So for the working temperature at 150 ° to 350 ° work under the condition of bearing, if rings and rolling body still choose ordinary high carbon chromium bearing steel manufacturing, it must be special tempering treatment was carried out on the bearing parts, shall generally be higher than working temperature tempering under 50 °. After tempering treatment according to the requirements of the bearing steel, can be used in normal working temperature. But after tempering hardness decreased, TIMKEN bearing life.
