    摘要： A revolution speed of balls 8, 8 constituting the outer side row is sensed by a revolution speed sensor 24. Also, a rotation speed of a hub 1a is sensed by a rotation speed sensor 25. A speed ratio as a ratio between a revolution speed and the rotation speed is calculated based on a sensed signal of both sensors 24, 25. When the axial load is changed and then the contact angles of the balls 8, 8 are changed, the revolution speed is changed and in turn the speed ratio is changed. Therefore, the axial load is calculated based on a change of the speed ratio.Accordingly, the configurations that can be manufactured at a low cost and is able to sense the axial load applied between the hub 1a and the outer ring 4a can be realized.

    摘要： The rolling bearing with a built-in motor includes a bearing part including an inner ring, an outer ring and a plurality of rolling elements, and a motor part including a stator and a rotor for driving and rotating the inner and outer rings of the bearing part with respect to each other. In the rolling bearing, the bearing part includes a first bearing ring having a cylindrical-shaped inner fixing portion formed in one end face of the inner ring so as to be coaxial therewith, and a second bearing ring having a cylindrical-shaped outer fixing portion formed in one end face of the outer ring so as to be coaxial therewith. When viewed in the radial direction of the rolling bearing, the stator and rotor are interposed between the inner fixing portion of the first bearing ring and the outer fixing portion of the second bearing ring.

    摘要： A fluid bearing motor having sufficient room for securing an air chamber for use in quickly discharging bubbles that have entered a thrust fluid bearing and a reservoir for supplying a lubricating fluid to the thrust fluid bearing. Moreover, the fluid bearing motor can easily be fabricated. The fluid bearing motor includes a shaft member 1, a sleeve 2 cooperating with the shaft member and a thrust collar 3 which is fixed to the shaft member 1 and extended in the diametric direction. The circumferentially-directed contour of the outer peripheral face of the thrust collar 3 is made elliptic, so that a reservoir 8 and an air chamber 9 are formed between the outer peripheral face of the thrust collar 3 and the face 4a of the mating member (sleeve).
