ROLLING BEARING DEVICE WITH SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a rolling bearing device with a sensor capable of sensitively determining the moment load acting on a trajectory member and the axial translation load. SOLUTION: The rolling bearing device with the sensor includes a rotational component estimator 701 that extracts a rotational synchronization component included in the rotation of an inner shaft 1 relative to an outer ring from each of a signal output by a first displacement detecting section and a signal output by a second displacement detecting section. The rotational component estimator 701 performs rotational operation and integration operation. COPYRIGHT: (C)2009,JPO&INPIT
