<P>PROBLEM TO BE SOLVED: To provide a rolling bearing with a sensor capable of eliminating the effect of an external magnetic field resulting from external noise. <P>SOLUTION: The rolling bearing with a sensor includes a rotating-side ring 2, a fixed-side ring 3, rolling elements 4 interposed between the rotating-side ring 2 and the fixed-side ring 3, a ring magnet 11 held on a magnet holder 12 fixed to the rotating-side ring, and a magnetic induction sensor 15 which is held by a sensor housing 16 fixed to the fixed-side ring and arranged opposite to the ring magnet 11 at a predetermined gap. The magnet holder 12 and the sensor housing 16 are formed of a magnetic substance. The magnet holder 12 and the sensor housing 16 are disposed so as to magnetically shield the gap between the ring magnet 11 and the magnetic induction sensor 15 from the outside. <P>COPYRIGHT: (C)2012,JPO&INPIT |
