  • low vibration slewing bearing disassembly

    The vibration signal of large slewing bearing was decomposed into different frequency bands by wavelet decomposition. The low frequency band spectrum was selected and analyzed to diagnose the fault combined with the method of energy spectrum analysis, which was proved to be more accurate and reliable than single wavelet spectrum analysis.

  • SY500H - SANY UK

    In real world operating condition, slewing bearings are sealed in machines and fully lubricated so the sensors are expected to be fix stably. Besides, low-frequency vibration signals are often submerged in strong background noise and the sensors which can collect ultra-low frequency vibration are needed.

  • The Condition Monitoring of Large Slewing Bearing

    2005-5-1 · Because the PPF controller does not work, after the slewing, the vibration amplitudes for the first two modes are large: 0.6338 mm, 0.2425 mm for the set-point control in Fig. 8 and 0.4994 mm, 0.1928 mm for the trajectory tracking control in Fig. 10. Comparing with these results, the tip deflections are effectively suppressed when the multi-mode PPF controller is applied to the PZT actuators.
