<P>PROBLEM TO BE SOLVED: To provide a structure capable of suppressing the effects of changes in the rigidity of rolling bearing units with changes in temperature and accurately determining loads exerted on the rolling bearing units. <P>SOLUTION: The amount of displacement in axial directions between an outer race 1 and a hub 2 is determined on the basis of the phase difference between detection signals of a pair of Hall ICs 11a and 11b. An axial load acting between the outer race 1 and the hub 2 is determined on the basis of this amount of displacement. The temperature of the outer race 1 is measured to remove the effects of changes in the rigidity of rolling bearing units with changes in temperature. <P>COPYRIGHT: (C)2007,JPO&INPIT |
