Technical Field

[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The early form of linear motion bearings was to place a row of wooden poles under a row of pry plates. Modern linear motion bearings use the same working principle, but sometimes balls are used instead of rollers. The simplest rotary bearing is a sleeve bearing, which is just a bushing sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, which replace the original bushing with many cylindrical rollers, and each rolling body is like a separate wheel.

[0003] When using the bearing structure to work, the traditional bearing structure usually has a simple configuration of the device, and the existing device is not precise enough, which leads to certain defects in the bearing, making the bearing not good enough in use, greatly reducing the use effect of the device.

[0006] As a preferred embodiment, a negative pole shaft ring is fixedly sleeved at an edge of the outer surface of the inner sleeve near the other side, and a negative pole shaft rotor is equidistantly connected to the outer surface of one side of the negative pole shaft ring along the circumferential direction.
