Abstract:
    A method and a device for assessing the remaining life of a rolling bearing capable of early and accurately estimating the life of the roller bearing based on the detected states of refuse and lubricating oil by detecting, at low cost, the mixing of the refuse in the lubricating oil and the state of deterioration of the lubricating oil by the mixing of water therein which largely affect the life of the rolling bearing by using the resonance frequency band signals and high frequency signals of an acceleration sensor. The device comprises, to know the relation of the mixed state of the refuse and the vibration of the rolling bearing (3) with the life of the bearing and the relation of the deterioration of the lubricating oil and the vibration of the rolling bearing (3) with the life of the bearing, a basic data collecting means obtaining vibration signals by using the acceleration sensor (4) for each specification of the bearing such as the model number and manufacturer
