[0002] Bearings are used to determine the relative motion position of rotating shafts and other parts, and are components that play a supporting or guiding role. They are components that fix and reduce the load friction coefficient during mechanical transmission.

[0003] The structure of the product can refer to a low-noise self-lubricating bearing structure disclosed in Chinese patent document 202420161708.4, including an outer ring, an inner ring, rolling elements and a retaining frame. A first oil pipeline and an annular oil storage groove connected to the first oil pipeline are provided in the outer ring. A second oil pipeline is symmetrically fixedly connected to one side of the annular oil storage groove, and an oil outlet limiting valve and an oil outlet nozzle are fixedly connected to one end of the second oil pipeline. An annular groove is provided at the position corresponding to the oil outlet nozzle on the retaining frame, and a number of through holes are provided on both sides of the annular groove. The lubricating oil flows out through the several through holes into each pocket of the retaining frame. This solution has the characteristics of being able to absorb the noise generated by bearing vibration and self-lubricate, thereby improving the service life of the bearing.

[0004] However, in this patent, the heat is dissipated by external equipment, and while the bearing is slowly oiled, there is no effect of dissipating the heat of the bearing.

[0005] A self-lubricating bearing structure made of composite material is now provided. Summary of the invention
