Kesalahan gigi rem
Perubahan kekakuan kontak gigi memicu frekuensi mesh gigi; kerusakan bisa mengmodulasi eksitasi tersebut.
Mechanisme
Perubahan kekakuan kontak gigi memicu frekuensi mesh gigi; kerusakan bisa mengmodulasi eksitasi tersebut.
Typical symptoms
Gugi ngalor-ngidul saka frekuensi rengkeng lan dampak bisa muncul.
Metode pengukuran
Cathet jumlah gigi lan kecepatan poros; periksa spektrum lan rata-rata sinkron nalika beban sing padha.
Alternative explanations
Normalisasi modulasi beban, eksentrisitas, dan jalur transmisi dapat mempengaruhi sampingan.
Pengukuran tambahan
Inspeksi permukaan gigi, analisis partikel minyak, pengukuran beban dan backlash.
Komponen frekuensi yèn mungkin
GMF = gigi × RPM / 60; GMF ± shaft Hz
Kaslahan: tanpa kontek kecepatan, beban, pemasangan lan jalur transmisi, conto iki ora diagnosis. Conto spectrum konseptual, ora model fault lengkap utawa pengukuran padha padha.
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.
