Abstract

Provided in the present invention is a bearing maintenance timing acquisition method: first, acquiring vibration signals of a bearing under different loads; then, respectively acquiring dimensionless parameters according to the vibration signal of each load; thus, acquiring predicted damage condition distribution data of the bearing under different loads according to the dimensionless parameters; and finally, obtaining accurate maintenance timing based on the predicted damage condition distribution data under different loads, so as to prolong the service life of the bearing while reducing maintenance costs.
