  • Installation of taper roller bearings
    Installation of taper roller bearings
    Tapered roller bearings are separable bearings. The inner and outer rings can be separated. The inner ring retainer assembly can be pressed onto the shaft. When the sleeve is pressed, it should be noted that one end of the sleeve should be placed on the end face of the outer ring and should not be placed on the inclined raceway surface.

  • What the hell is with the bearing packaging?
    What the hell is with the bearing packaging?
    When all of the parts are made, the bearing needs to be put together. First, the inner race is put inside the outer race, only off to one side as far as possible. This makes a space between them on the opposite side large enough to insert balls between them.

    The fault diagnosis technology of needle bearing mainly includes vibration diagnosis technology, iron spectrum diagnosis technology, temperature diagnosis technology, acoustic diagnosis technology, oil film resistance diagnosis technology and optical fiber monitoring diagnosis technology, among which vibration, iron shop and temperature diagnosis technology are widely used.
  • Check and troubleshoot in operation
    Check and troubleshoot in operation
    The inspection items in operation include rolling sound, vibration, temperature and lubrication state of the bearing. The specific conditions are as follows:
  • How to determine whether the bearing can be used again?
    How to determine whether the bearing can be used again?
    Check the condition of raceway surface, rolling surface and mating surface, as well as the wearing condition of the cage, etc. In addition, the degree of bearing damage, machine performance, importance, operating conditions, inspection period, etc., will be considered before determining whether the bearing can be used again or replaced. If bearing damage and abnormal conditions are found, find out the cause and develop countermeasures.
  • Bearing clearance selection
    Bearing clearance selection
    In the same way as bearing lubrication, excessive or too little grease will cause bearing temperature changes, resulting in bearing damage; similarly, bearing clearance is too large or too small, the bearing's working life and even the stability of the entire equipment operation will be reduced.
  • What are the specific requirements for the packing of the bearing?
    What are the specific requirements for the packing of the bearing?
    After the bearing is manufactured and tested, it is cleaned and treated with rust, and then put into the inner package to achieve the purpose of waterproof, moisture-proof, dustproof, shock-proof, maintaining the quality and precision of the bearing as well as making it convenient to use and sell.
  • Bearing failure always bothers you because you don't understand the following.
    Bearing failure always bothers you because you don't understand the following.
    Bearing in the work, due to the influence of external or internal factors, the original matching clearance changes, the accuracy decreases, and even causes "bite dead" is called "clearance change failure. External factors such as excessive interference, improper installation, expansion caused by temperature rise, instantaneous overload, etc.
  • Bearing selection is not right, do not say the bearing quality bad
    Bearing selection is not right, do not say the bearing quality bad
    "" various types of bearings have different characteristics due to different designs. Due to the bearing's specific location of installation and the variability and complexity of application, bearing type selection without fixed mode can be used to adapt to a certain host specific location of installation and application conditions for bearing type selection, it is recommended to take comprehensive consideration according to the following main factors."
  • Adjust the bearing after installation
    Adjust the bearing after installation
    When installing, do not directly hammer the bearing end face and non-bearing face. Press the block, sleeve or other mounting tools should be used to make the bearing uniformly stressed. If the interference fit is larger, should put the bearing into the mineral oil in installation as soon as possible after heating to 80 ~ 90 ℃, strictly control the oil temperature does not exceed 100 ℃, in order to prevent the effect of tempering hardness decrease and recovery effect size.

    Method Of Bearing Fault Diagnosis On A permanent magnet synchronous motor (PMSM)
    A permanent magnet synchronous motor (PMSM) is a typical electromechanical system widely used in industrial automation. Bearing fault diagnosis is necessary because a bearing is a key and vulnerable component in a PMSM.

    Bearing Fault Feature Analysis
    BEARINGS are among the most important machine components in the vast majority of rotating machines and exigent demands are made upon their carrying capacity and reliability. Generally, a rolling bearing cannot rotate for ever. It often works well in non-ideal conditions, but sometimes minor problems cause bearings to fail quickly and mysteriously without any notable warning.

    Replacement and replacement cycles of lubricants
    In order to ensure that the lubrication of the bearing is always in good condition, the lubricating oil should be replaced regularly when lubricated by oil. Oil bath lubrication as long as the operation temperature is not more than 50 ℃, and

  • Rolling-element bearing outer race fault detection
    Rolling-element bearing outer race fault detection
    Rolling-element bearings are widely used in the industries today, and hence maintenance of these bearings becomes an important task for the maintenance professionals. The rolling-element bearings wear out easily due to metal-to-metal contact, which creates faults in the outer race, inner race and ball. It is also the most vulnerable component of a machine because it is often under high load and high running speed conditions.
  • How to choose the correct grease to improve the service life of the bearing
    How to choose the correct grease to improve the service life of the bearing
    Grease is alubricant consisting of base oil, thickener and additive. Common lubricating grease of bearing include calcium base grease, sodium base grease, calciumsodium base grease, lithium base grease, aluminum base grease and molybdenumdisulfide grease. The amount of grease in the bearing should be reduced to 1/3at high speed. Too much grease will increase the working temperature of the bearing. When choosing lubricating grease, the working temperature, bearingload and speed are considered.
