There is indeed a bearing fault; the frequency component is difficult to hide.
Look at the low frequency of the spectrum first; see if there is any non-synchronous
If there are non-synchronous components; the problem can be fixed by three points,
Characteristic frequency harmonics exist; there is no doubt about the corresponding problem,
Look at the high frequency of the spectrum; the modulation is ill,
Outer ring features are transposed; loose appearance is no doubt,
The inner ring is faulty; it can also be used as a basis.
Special circumstances are particularly important; the diagnosis of the disease is measured,
If a single frequency exists, can the bearing be identified.
High frequency is also very important; early high frequency points,
There is no high frequency in the low frequency; it is often diligent to stalk.
If the damage is serious, the high frequency is raised,
Timely replacement Mo lucky; time to prevent things from happening.
The mechanism of the disease is clear; it is necessary to be clear,
Smooth conditions are often detected; debugging installation is not relaxed,
There are tricks in the diagnosis of a bearing; trust science can't be wrong.
