Bearing with power generation function

Abstract

The invention discloses a bearing with a power generation function. A ring-shaped rotor is fastened to an inner bearing ring. All roller pins are evenly installed on a roller pin retaining ring. The roller pin retaining ring is fastened to the outer ring face of the ring-shaped rotor. A roller pin guide rail ring is fastened to the inner ring face of a ring-shaped stator. An outer bearing ring is fastened to the outer ring face of the ring-shaped stator. All the roller pins are limited to roll in the roller pin guide rail ring. The ring-shaped rotor is evenly provided with multiple pieces of magnetic steel in the circumferential direction of the circular ring of the ring-shaped rotor. The ring-shaped stator is evenly provided with a plurality of copper wire windings in the circumferential direction of the circular ring of the ring-shaped stator. All the copper wire windings are connected in series continuously and a pair of leads is led out from the copper wire windings. The magnetic steel forms a magnetic field. When the inner bearing ring rotates, a magnetic force line is cut by the copper wire windings, and an electric current is generated. According to the bearing with the power generation function, a power generation mechanism and the bearing structure are reasonably assembled into a whole, so that the bearing is simple in structure and small in size; on the premise that the power generation function of the bearing is achieved, the relatively simple bearing structure is maintained.

Description

technical field [0001] The invention relates to a bearing, in particular to a bearing with power generation function. It is used in occasions where it is necessary to supply power while using bearings to rotate, or to convert and store kinetic energy into electrical energy. Background technique [0002] Bearings are precision mechanical devices. There are applications in various industries and fields. However, for example, in industries such as wind power generation, motor servo, automobiles, and electric vehicles, there are demands for electrical energy conversion and storage along with rotation. For this requirement, in addition to the bearing, it is generally used in combination with a transmission mechanism and a power generation mechanism to achieve the purpose. This kind of mechanism is not only complex in structure and takes up a large space, but also has a high cost and is troublesome to maintain and replace.
