| Abstract | This damage analysis system for large-sized bearings and driveshafts is a maintenance system that enables diagnosis and preventive maintenance without disassembling components in service to inspect for fl aking failure, wear, etc. Sensing and abnormality diagnostic technology during low-speed rotation with large external disturbance and energy-effi cient, high-performance wireless communication technology were indispensable to the development of the system. Although verification by a system model is still being carried out, development is nearly complete, therefore a portion of the concerned technology is introduced in this paper. |
