Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy oil-containing bearings, in particular to a powder metallurgy oil-containing bearing. Background Art

[0002] Powder metallurgy oil-containing bearings refer to sliding bearings made of porous materials with lubricating oil stored in the pores. The porous material and the lubricating oil have different thermal expansion coefficients, so when working, the oil is squeezed into the friction surface from the pores. When working stops, the oil is absorbed back into the pores as the temperature drops. Existing powder metallurgy oil-containing bearings are more convenient to use, thereby improving their efficiency.

[0003] Chinese utility model patent CN220956146U discloses a high-speed, high-wear-resistant powder metallurgy oil-containing bearing, comprising a bearing body, a plurality of connection holes on one side of the top of the bearing body, a one-way valve being rotatably connected to one side of the inner wall of each of the plurality of connection holes, and a plurality of storage tanks on one side of the inner wall of the bearing body. The high-speed, high-wear-resistant powder metallurgy oil-containing bearing described in the utility model is provided with connection holes, one-way valves, storage tanks, adsorption sponges and penetration holes. The connection holes are used to inject lubricating oil, the one-way valves are used to prevent the internal lubricating oil from leaking out, the storage tanks are used to store the injected lubricating oil, the adsorption sponges are used to adsorb the lubricating oil, the lubricating oil inside the adsorption sponges is slowly discharged, and the lubricating oil is discharged to the surface of the rotor through the penetration holes, so as to provide the rotor with a high speed effect, thereby achieving the effect of conveniently adding lubricating oil to the rotor inside the bearing and preventing it from leaking.

[0004] However, the high-speed and high-wear-resistant powder metallurgy oil-containing bearings mentioned above do not have the function of dehumidifying the bearings. Since the bearings are exposed to the external environment for a long time, the external humid gas can easily corrode the bearings, making the bearings prone to rust, thereby affecting the service life of the bearings.
