Misalignment
Connected shaft axes differ in angle or offset. Coupling type at thermal behaviour matter.
Mechanism
Connected shaft axes differ in angle or offset. Coupling type at thermal behaviour matter.
Typical symptoms
Axial vibration at 1×/2× components may increase; the pattern depends on coupling and load.
Methode ng pagkakabadyet
Maging tatlong axis sa dalawang panig ng coupling at compare phase sa parehong speed.
Alternative explanations
Mga sumunod na patao, pagkakapal, at pagkakabukas ng shaft ay maaaring magpabuo ng kapareho ng mga pattern.
Additional measurements
Laser alignment, pagtse ng paa, init/lamig na posisyon ng shaft at pag-iinspektong coupling.
Likely frequency components
1×, 2×; harmonics / armónicos
Mga limitasyon: nang walang speed, load, mounting, at transmission-path context, hindi ito diagnoses. Ang spectrum examples ay conceptual, hindi complete fault models o field measurements.
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.
