<P>PROBLEM TO BE SOLVED: To provide a measuring method for load on a rolling element and a bearing for measuring the load capable of accurately measuring the load on the rolling element at the bearing which contact angle varies when an axial load is acting on. <P>SOLUTION: In a rolling inner wheel 13 or an outer wheel 11, a notch groove 16 whose groove bottom surface angle 17 is set rectangular to the line 18 of mean value α1 of an initial contact angle α0 and a contact angle α2 at the time of maximum axial loading, is formed. On the groove bottom surface 17 of the notched groove 16, two sheets of 2-axis strain gauges 19, 19 are pasted. The axial direction position for pasting the strain gauges 19, 19 is a position evenly split in the axial direction for the mean value line 18. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
