Kelesakan mekanik
Sambungan longgar utawa lempengan bearing bisa bikin kontak non-linear lan impact.
Mechanisme
Sambungan longgar utawa lempengan bearing bisa bikin kontak non-linear lan impact.
Typical symptoms
Harmonik, dampak lan fase variabel bisa muncul. Gejala bisa berubah kanthi beban.
Metode pengukuran
Inspect waveform berdampingan dengan spektrum; perbandingkan fondasi dan lokasi bearing.
Alternative explanations
Goresan, dengesan lan kesalahan pasangan sensor bisa bikin harmonik.
Pengukuran tambahan
Torsi penangkal, pemeriksaan retak, pemeriksaan jarak, lan bentuk defleksi operasi.
Komponen frekuensi yèn mungkin
1×, 2×, 3× …; subharmonics possible
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.
