There are many causes of bearing failure, all of the design and manufacturing process factors and timken bearing failures, their analysis is not easy to determine. Under normal circumstances, in general, you can consider and analyze the factors and internal factors.
The main factor is used to adjust the installation, use and maintenance, maintenance, etc. meet the technical requirements. Install the premise is to use one of the factors bearing is often caused by incorrect installation package state changes between the various departments of the loading capacity of the primary factor in the abnormal state of manipulation and early failure. According timken bearing installation, use, maintenance, repair bearing manipulation techniques required to withstand the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, immediately find the cause of abnormal, adjust it back to normal. In addition, grease and close the media quality, the atmosphere is very important analytical tests.
(1), bearing in order to keep their work environment clean.
Even if the eyes can not see fine dust that will have adverse consequences timken bearings. Therefore, to maintain the neighborhood clean so that dust does not enter the bearing.
(2), be used with caution.
Bearing in use to give a strong impact, there will be a scar and indentation, cause of the accident. Severe cases, cracks, breaks, be sure to pay attention.
(3), using an appropriate manipulation tool.
Avoid existing tools instead, you must use the correct tools.
(4), note bearing erosion.
Bearing operation, the hand will rust due to sweat. Pay attention to clean your hands manipulated the best possible wear gloves.
timken bearing temperature, generally bearing chamber outside temperature can be inferred that if the hole can be directly measured using the bearing outer ring temperature is more suitable position.
Typically, the bearing temperature began to rise slowly along the bearing running 1-2 hours after the chaos state. The normal temperature because of the machine bearing the heat capacity, heat capacity, speed and load are different. If lubrication, install the appropriate department, the abrupt timken bearing temperature will rise, arise from an abnormally high temperature, then must stop running, take the necessary precautions.
Thermal sensors can be readily monitored using the bearing operating temperature, and realize the value automatically when the temperature exceeds the delineation of inactivity to prevent burning shaft alarm or accident.
Often expressed with high temperature bearings in unusual circumstances. Temperature is harmful to the 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. Caused by high bearing the following reasons: lack of lubrication or excessive lubrication, lubricant. Containing impurities, the load is too large, the bearing ring damage, lack of space, and produce high-friction seals and so on.
Therefore, continuous monitoring of bearing temperature is necessary, whether it is measured timken bearing itself or other important parts. If it is in operation under the same premise, the temperature change can be said of any fault has occurred.
Bearing temperature measurement by means of periodical thermometer, such as digital thermometers, bearing temperature can be accurately measured and determined in accordance ℃ or Fahrenheit units.
The importance of bearing, which means when it is damaged, can cause equipment downtime, so these should preferably be installed timken bearing temperature detectors.
