It is proposed to discriminate working conditions of rolling bearing with Hilbert envelope demodulation in consideration of the fault diagnosis involving such disciplines as machinery, signal processing, advanced mathematics and vibration as well as combining with the working conditions of field equipment and specific circumstances of spot check personnel. The practicability and effectiveness of the method in fault diagnosis for rolling bearing of speed increasing machine for rolling mill are verified through analyzing field data with the intelligent point detector encapsulated with Hilbert envelope demodulation circuit.
