Check KOYO bearings during operation working condition

    How to Check KOYO bearings in an operating state, first from the bearing vibration, scroll and temperature of three to talk about:
    First, check the bearing vibration at work
    Flaking, creasing, corrosion, cracks, wear and tear and will reflect the view in the the KOYO bearing vibration measurement, the KOYO bearing vibration damage to the bearings is very sensitive, so, by using a special bearing vibration measurements (frequency analyzer etc.) can measure the size of the vibration frequency points can not be inferred abnormal circumstances. Since the measured values due to the conditions of use of the bearing or sensor installation location and the measured value of each machine in advance analysis and comparison of determined criteria.
    Second is to check the bearing rolling sound
    KOYO bearings even a slight peeling and other damage, will be issued abnormal tone and irregular sound, sound measuring device can be distinguished, the use of sound measuring device to check the size of the operation of the bearing rolling sound and sound quality, play the role of prevention in advance.
    The final step is to check the temperature of the bearing rotation
    If you use the hole can directly measure the temperature of the bearing outer ring is more suitable. Under normal circumstances, KOYO bearing temperature, generally depending on the outside of the bearing chamber temperature can be inferred. Lubrication, install the appropriate department, the bearing temperature will rapid-rise abnormally high temperatures, there will be time to stop running, to take the necessary precautions. Typically, the bearing temperature rise slowly as the operation starts steady state reached after 1-2 hours. KOYO bearings normal temperature due to the the machine heat capacity, heat dissipation, speed and load. If necessary, use the thermal sensor can monitor bearing temperature, and automatic alarm when the temperature exceeds the specified value households or stop to prevent burning shaft accident.
