Inner ring outer ring rolling element, characteristic frequency should be kept in mind
There are indeed bearing faults, and the frequency components are difficult to hide.
Look at the low frequency of the spectrum first, see if there is an asynchronous
If there is a non-synchronous component, the fault can be determined by three points.
Characteristic frequency harmonics are stored, no problem corresponding to the fault
Look at the high frequency of the spectrum, the modulation is faulty.
Outer ring features are frequency-shifted, loose phenomenon is no doubt
Inner ring fault transposition, can also be used as evidence components
Special circumstances, special attention, diagnostic faults are measured
If a single frequency exists, whether the bearing needs to be identified
High frequency is also very important, early failure high frequency points
There is no high frequency in the low frequency, and it is often hard to follow.
If the damage is serious, the high frequency rises and there is a hole.
Timely replacement of Mo Yuki, always avoid accidents
The mechanism of failure is clear, and it is necessary to distinguish between right and wrong.
Lubrication conditions are often detected, debugging assembly is relaxed
Diagnosing the bearing is flawed, I believe that science can't be wrong.
