According to the characteristics of low-speed and heavy-load bearings, a resonance demodulation method suitable for low-speed and heavy-load bearing fault diagnosis is proposed. The vibration signal of the slewing bearing rolling bearing of the bucket wheel stacker and reclaimer is picked up by a self-made low-frequency acceleration sensor. This method is used to diagnose the fault, and the diagnosis result is reliable. Keywords: low-speed and heavy-load bearing; resonance demodulation; fault diagnosis; low-frequency acceleration sensor
