Rolling bearing fatigue state prediction device and rolling bearing fatigue state prediction method

摘要

There are provided a rolling bearing fatigue state prediction device and a rolling bearing fatigue state prediction method capable of highly accurately predicting a fatigue state of a rolling bearing even when a direction of a load applied to a rolling bearing changes. A rolling bearing fatigue state prediction device 1 includes a load measurement unit. (8a to 8h, 12) for determining a magnitude and a direction of a bearing load applied to a rolling bearing 2 supporting a rotating body 3, a load applied region identification unit 13 for identifying a region to which a load is applied in a circumferential region of the rolling bearing 2, and a fatigue state prediction unit.14 for predicting a fatigue state of the rolling bearing 2 based on the obtained magnitude of the load and the identified load applied region.
