| Abstract: | Presented a new fault diannosis system for the gear speed reducer, rolling bearing based on advancing DSP technolony, and provided a feasible strategy. According to the analysis of vibration sign , using the envelope demodulation and FFF methods, improved the calculation precision for the rolling bearing diagnosis . The responding time delay of conventional circuit in the monitor system was effectively improved. The sensitivity and resolution of the monitoring and alarming system for the instant fault were also improved for the nmning gear speed reducer. |
