Ffurfiau mesh gear
Newid stiffness cysylltiad toothed excites gear mesh frequency; damage can modulate that excitation.
Mechanism
Newid stiffness cysylltiad toothed excites gear mesh frequency; damage can modulate that excitation.
Symptomau tyypol
Ffônfeddal ysgol ffrwyth a chreuau ar y ffrwyth mesurir yw'n gallu cael eu gweld.
Mynediad methodeg
Rhanbwyntio enwiau tooth a chyflymachau safon; inspectiwch y spectrum a'r average synchrognol ar lefer cymharf.
Tystiolaeth uchaf
Modd modd, eccam a chynllwyniau trysorol can tynnau sidebands.
Manyleb thefawr additional
Gwahannau ddant, analisia oil, trefnu a chreu.
Cymunedau ffrwyth sy'n lwf.
GMF = teeth × RPM / 60; GMF ± shaft Hz
Llifau: heb brysur bys, llawn, cysylltiad lleoliol a chynllun trawsfyn, nid yw hynny yn diagnozu. Effeithiau spektrum yw cymysgedd, nid modelau defnydd i'r awdl, neu datrys unigryw.
SIMULATED · NOT LIVE TELEMETRY
Vibration / FFT
Model and assumptions
512 samples; deterministic sinusoids and seeded noise. FFT is one-sided peak amplitude, not RMS. Δf = fs/N. Hann coherent gain is corrected; spectral leakage can remain. The 4.7× component is not a physical bearing-fault model.
Educational model. Results are not sufficient to diagnose a machine or establish safe operating limits.
