a description for virbation monitoring of industrial bearings states:
peak amplitues at 1 x rpm
should be an indicator for a fault in my case. Can somebody explain me what I have to understand under 1 x rpm. My chart (FFT) shows Amplitude in m/s^2 on the y-axis and Frquency in [Hz] on the x-axis.
Do I need to know how much rotations my bearings do in one minute? If somebody can give an example, also was 2 x rpm mean and how I calculate this value?
Thanks in advance!
