Japanese Patent JP6915478
Kind Code:
B2
Abstract:
A rolling bearing device includes a bearing portion and a power generation portion. The power generation portion has a plurality of projecting portions provided on an outer ring spacer, a pair of core members provided on an inner ring spacer, a magnet, and a coil. The power generation portion generates an induced current in the coil as the projecting portions pass in the vicinity of first side end portions of the core members during rotation. There are two different loop paths along which magnetism generated by the magnet flows: a first loop path formed when the projecting portions are close to the first side end portions of the core members; and a second loop path formed when the projecting portions and the first side end portions of the core members are away from each other.
