Detecting High Frequency Faults of Ball Bearing with Wireless Accelerometer Sensor

Ball bearing is one of the most widely used and critical parts in machines. The failure of rolling element bearings is one of the most important causes of breakdown in rotary machines. Vibration of each machine is a good factor in realizing the condition of machines. So far, various vibration-based techniques have been developed for analyzing vibration signals. These methods are used in different domains to monitor the condition of bearings. Wireless modules can be used to solve the limits of access in machines especially in rotating machinery.In this paper, a wireless accelerometer sensor for remote condition monitoring of rolling bearings has been developed. The fabricated system works in high sample rate and has been tested on six roller bearings with different defects. This project shows that wireless sensors offer an effective method for monitoring key parts of machines continuously and remotely.
