<p>To predict a correction rated life with high accuracy. A life predicting device executes steps S1, S2, S4 for inputting specification information including basic dynamic rated load C and basic static rated load C0, step 5 for computing an equivalent load P based on the specification information, step S3 for setting a reliability factor a1, steps S7 and S8 for determining a contact ellipse area S, step S9 for inputting debris purchasing diameter ddebris, step 10 for determining a standardized debris diameter (ddebris/√S), step S11 for setting a life correction factor axyz based on the standardized debrics diameter, and steps S6 and S12 for calculating a correction rated life Lnm based on the reliability factor, the life correction factor, the basic dynamic rated load and the equivalent load.</p> |
