Kerusakan bearing
Defek lokal pada permukaan berguling bisa menghasilkan dampak saat kontak melewatinya.
Mechanisme
Defek lokal pada permukaan berguling bisa menghasilkan dampak saat kontak melewatinya.
Typical symptoms
Dampak frekuensi tinggi lan frekuensi istimewa ing spektrogram envelop bisa muncul.
Metode pengukuran
Dapatkan percepatan kanthi bandwidth cukup; dokumenta band envelope lan pemasangan sensor.
Alternative explanations
Kawruh minyak, dampak listrik lan proses bisa ngasilake energi sing padha
Pengukuran tambahan
Geometri bearing, beban, kecepatan, analisis pelumas, suhu dan tren waktu.
Komponen frekuensi yèn mungkin
BPFO, BPFI, BSF, FTF ± 1×
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.
