PROBLEM TO BE SOLVED: To provide a general-purpose deterioration curve creation method for evaluating the deterioration state of a rotary machine on the basis of the measurement of wear particles in lubricating oil and a machine life prediction method for predicting the remaining life of the rotary machine by using the general-purpose deterioration curve creation method.;SOLUTION: A genera-purpose deterioration curve creation method for evaluating the deterioration state of a rotary machine having a bearing to be operated in lubricating oil includes: a drive step of rotating a shaft body by using a test machine 1 comprising a shaft body 3 and a bearing 2 for rotating the shaft body in lubricating oil 4 by applying a load L; a measurement step of measuring the number of wear particles in the lubricating oil, and calculating a deterioration state value based on the number of the wear particles; a deterioration state value collection step of repeatedly measuring the number of wear particles, and collecting the deterioration state values of each time; and a general-purpose curve creation step of creating a change in the collected deterioration state values as a general-purpose deterioration curve.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
