A new smart bearing based on the embedded multi-parameter sensors was proposed herein, which was the integration of two accelerometer sensors, two rotational speed sensors and two temperature sensors on the bearing. It can monitor the horizontal and vertical vibrations of the bearing, and also the speed and the temperature. A new conjunctive structure of the compound sensor and the bearing was developed, which integrated compound sensor into bearing by a groove manufactured on outer raceway of the bearing. The principle prototype of smart bearing test rig was also developed to test and verify the performance of the smart bearing, and the results show the performance advantage when using the smart bearing to do condition monitoring.
