  1.The rolling sound of Timken round roller bearings
  They are the usage of a sound detector to check the scale and audio high-quality of the rolling sound of the bearing during operation. Even if the bearing is slightly damaged, along with peeling, peculiar sounds and irregular sounds can be emitted, which may be distinguished by the sound detector. Using listening to perceive abnormal movements is a time-honored technique. As an instance, the use of an electronic stethoscope to hit upon odd noise from an element is a technique used by experienced operators. If the bearing is in the right non-stop rotation, it's going to emit a low whining sound. If it produces sharp hissing, squeaking, and different irregular sounds, it frequently indicates that the bearing is in a bad non-stop rotation situation. The sharp creak may be caused by unsuitable lubrication. Fallacious bearing clearances also can purpose metal noise. The indentation of the concave music on the bearing outer ring song will purpose vibration and create an easy and crisp sound. If it is because of knocking injuries brought about all through set up, the noise will also be generated, and this noise will vary with the speed of the bearing. If there's intermittent noise, the rolling factors can be damaged. Whilst the broken floor is rolled over, infection in the bearing often reasons a hissing sound. Extreme bearing harm can produce abnormal and loud noises.
  Bearing harm can be detected by way of listening to; however, generally, the bearing ought to be replaced at the moment. Consequently, a higher method is to apply SKF electronic situation tracking. In comparison with the old manner of using a wooden stick or screwdriver to endure at the bearing container and the opposite end towards the ear, the new invention can make certain a more secure and greater correct estimation of the bearing circumstance.
  2.The temperature of Timken spherical roller bearings
  The temperature of the bearing can normally be measured from the warmth outside the bearing. it's far greater appropriate if the temperature of the outer ring of the bearing can be directly measured the use of the oil hole.
  typically, the temperature of the bearing regularly rises because the bearing starts to run, and reaches a constant-nation after 1-2 hours. The common temperature of the bearing varies with the machine's warmth potential, warmness dissipation, velocity, and load. If the lubrication and installation are not appropriate, the bearing temperature will upward push sharply, and abnormally high temperatures will occur. at the moment, the operation need to be stopped, and the essential precautions need to be taken. the use of a thermal sensor can monitor the working temperature of the bearing at any time, and realise automated alarm or forestall while the temperature exceeds the required value to prevent a shaft coincidence.
  excessive temperatures frequently indicate that the bearing is in an abnormal circumstance. excessive temperatures are dangerous to bearing lubricants, and from time to time bearing overheating also can be attributed to bearing lubricants. lengthy-time period continuous rotation of the bearing at a temperature exceeding one hundred twenty five ° C will reduce the bearing life. reasons of taking excessive temperatures encompass inadequate lubrication or excessive lubrication, impurities contained inside the lubricant, unreasonable load, bearing harm rings, inadequate clearance and excessive friction as a result of oil seals, and many others.
  therefore, it's miles vital to screen the bearing temperature continuously, whether or not it measures the bearing itself or other vital elements. If the running situations are not changed, any temperature exchange can indicate that a failure has passed off. The periodic measurement of bearing temperature can be accomplished with the assist of a thermometer. for example, if a virtual thermometer can appropriately measure the bearing temperature and display it in ° C or Fahrenheit. surprisingly appropriate bearings will reason gadget shutdown while they're broken. therefore, it is excellent to put in a temperature detector for those bearings. beneath normal circumstances, the bearing may have a natural temperature upward thrust without delay after lubrication or re-lubrication and closing for one to 2 days.
  3.The vibration of Timken spherical curler bearings
  Bearing vibration may be very touchy to taking harm, including peeling, indentation, rust, crack, wear, and many others. could be reflected within the bearing vibration measurement, so the vibration can be measured by the use of a selected bearing vibration measuring device (frequency analyzer, and so forth.) the size of the unusual state of affairs cannot be inferred from the frequency. therefore, it's far important to examine and evaluate the measured values ​​of every device earlier to determine the judgment widespread.
