How to measure the operating temperature of thrust ball bearings
Thrust ball bearing temperature, generally by the bearing chamber outside temperature can be inferred that if the use of the hole can be measured directly thrust ball bearing outer ring temperature, the more appropriate.
Typically, thrust ball bearings with the four point contact ball slewing bearing operating temperature slowly began to rise 1-2 hours to reach steady state. Normal temperatures thrust ball bearings due to the heat capacity, heat capacity, speed and load of the machine and different. If lubrication, improper installation, the bearing temperature will be rapid-rise, there will be abnormal high temperature, when to stop running and take the necessary precautions.
You can always use the thermal sensor to monitor the thrust ball bearing operating temperature, and automatic alarm or stop to prevent burning shaft accident temperature exceeds a predetermined value.
Often expressed with a high temperature thrust ball bearings in unusual circumstances. Temperature is harmful to thrust ball mobile crane bearing lubricant. Sometimes bearing overheating can be attributed to the bearing lubricant. If the bearing temperature over 125 ℃ even move to reduce long bearing life. Causes high temperature bearings include: lack of lubrication or excessive lubrication, lubricant. Contains impurities, the load is too large, the bearing ring damage, lack of space, and high-friction seals and so on.
Thus, continuous monitoring of bearing temperature is necessary, whether measured bearing itself or other important parts. If you are under the same operating conditions, any change in temperature may indicate a fault has occurred.
Thrust ball bearing temperature measurement by means of regular thermometer, such as digital thermometers, bearing temperature can be accurately measured and determined in accordance with ℃ or Fahrenheit units.
The importance of thrust ball bearings, which means when it is damaged, can cause equipment downtime, so the best type of bearing temperature detectors should be installed.
Under normal circumstances, thrust ball wind power bearing lubricated or relubricated immediately after the temperature increase, and there will be natural for one or two days.
