Fualan gearan
Feuchamaich stiùc airson gear mesh frequency; damage can modulate that excitation.
Mechanism
Feuchamaich stiùc airson gear mesh frequency; damage can modulate that excitation.
Symptoms a-mhàin
Sìdean-spaced sidebands airson gear mesh frequency agus impacts may appear.
Measur method
Clàrnaich àireamhan fiaclan agus fuasgladh shàth; sgrùchaidh speitreas agus meadhan síncronach aig lòd comasach.
Alternative explanations
Leasachadh leasach, eacair agus na tarraingthean aig aice a th' ann an a-mhàirtean.
Additional measurements
Sianes iadail chuidan, cleachdadh oilthigh, measuradh a-mach agus a-muireach.
Componan fhreagairteach a-staigh
GMF = teeth × RPM / 60; GMF ± shaft Hz
Lìonachaisean: airson gu bheil am spèid, a' chur le chéile, aithris agus a-chur-thogail ann an cànan, chan eil na h-èifeachdannan seo diagnoses. Chan eil na h-amplean speactra comhradh-chleachdadh no measan airson a' chnoc.
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.
