Shutdown Detection of Mechanical Parts

  • Mechanical parts play a vital role in the use of machinery, so we must carry out regular maintenance and repair.
  • In order to improve the service performance of mechanical equipment and prolong the service life of mechanical parts, when the machinery is shut down, it is necessary to detect the correlation of mechanical parts to ensure the use of parts.
  • It is important to keep the bearings and lubrication clean.
  • Clean the surface of the machine before inspection, and then remove the parts around the bearing. The oil seal is a very fragile part, so it needs to be disassembled carefully.
  • Do not apply excessive force, and then carefully check the oil seal and its surrounding parts. If there are bad symptoms, be sure to replace it. The bad oil seal will lead to bearing damage and strict equipment shutdown.Shutdown Detection of Mechanical Parts
  • Check lubricant
  • Rub a little lubricant between your fingers. If there are pollutants, you can feel it, or apply a thin layer of lubricant on the back of your hand, and then seal it for light inspection.
  • Change lubricant
  • After draining out the old oil, if possible, refill fresh oil into the oil lubricated bearing and let the machine rotate at low speed for a few minutes. Make the engine oil collect residual pollutants as much as possible, and then drain the engine oil. The engine oil should be filtered before use.Shutdown Detection of Mechanical Part
  • For grease lubricated bearings, the arbor used when replacing grease should avoid connecting the angle of cotton to any part of the bearing, because these residual fibers may wedge between the rolling parts and cause damage, especially for the application of small bearings.Shutdown Detection of Mechanical Parts
  • Cover exposed bearings
  • When inspecting the bearing, never expose the bearing to pollutants or moisture. If the work is interrupted, the machine shall be covered with oil paper, plastic sheet or similar materials.Shutdown Detection of Mechanical Parts
  • If it is possible to clean the naked bearing without disassembly, clean it with a brush coated with white spirit, and then dry it with a piece of lint free cloth or blow dry with compressed air (be careful not to start the rotation of the bearing assembly).Shutdown Detection of Mechanical Parts

Shutdown Detection of Mechanical Parts

  • Scope of application: the new technology developed in recent years is rarely used in bearing condition monitoring.Shutdown Detection of Mechanical Parts
  • When taking the oil-free bearing directly by hand, fully wash the sweat from your hands and apply high-quality mineral oil before operation. 
  • Pay special attention to rust prevention in rainy season and summer. Under some special operating conditions, the service life of angular contact ball bearing can be longer than that of traditional calculation, especially under light load. 
  • These special operating conditions are the surface damage that may be caused when the rolling surface (track and rolling parts) is effectively separated and limited by a lubricating oil film. In fact, under ideal conditions, the so-called permanent bearing life is possible
  • It is not allowed to punch with force, directly knock the bearing with a hammer, and transfer pressure through the rolling element.Shutdown Detection of Mechanical Parts
  • As soon as the angular contact ball bearing rotates, the raceway surface of the inner ring and the outer ring is in rolling contact with the rolling element, so the running track is a dark surface. 
  • The running track attached to the raceway surface is not abnormal, so the load conditions can be known. Therefore, please pay close attention to and observe the running track of the raceway surface when disassembling the oil-free bearing.
