how detect key wear for turning machine ?
(OP)
Hello
i made a measurement on a spindle machine with keys to fixe gears on the shaft spindle.
and i have a 155Hz peak with 2 side bands of 38,8Hz
the turning speed is also 38,8Hz.
Dou you think it could be key wear ?

thank you very much

It sounds like you have harmonics of 3x, 4x, 5x of running speed.
Impacting at 1x such as from looseness can generate a series of harmonics peaking near resonance of the component being impacted.
