AI Technical Summary
During the use of oil-containing bearings, oil will seep out, causing some oil to seep out from both ends of the bearing when rotated for a long time, affecting the service life and retention of oil.
An oil-containing bearing is designed, with a first through hole and a flow guide surface on the inside of the body, and a barrier ring and an oil storage chamber are formed at the port. The second through hole is located inside the port and is directed to the oil storage chamber through the guide surface. The barrier ring stores some oil. When the rotation is stopped, the stored oil is absorbed into the bearing again.
It extends the service life of oil-containing bearings, reduces oil leakage, and improves the retention effect of oil through storage and reabsorption mechanisms.

Technical Field
[0001] The utility model relates to the technical field of oil-containing bearings, in particular to an oil-containing bearing. Background Art
[0002] Oil-containing bearings, that is, porous bearings, use metal powder as the main raw material. Oil-containing bearings are sintered bodies made by powder metallurgy. They are inherently porous and have the technical advantages of being able to freely adjust the number, size, shape and distribution of pores during the manufacturing process. The oil-containing bearing is rotatably connected to the connecting piece, and the friction and high temperature cause the oil inside the oil-containing bearing body to seep out. If it rotates for a long time, some of the oil will seep out from both ends of the oil-containing bearing body. Utility Model Content
[0003] The utility model aims to provide an oil-containing bearing to solve the problem in the above-mentioned background technology that the oil-containing bearing is rotatably connected with the connecting piece, friction and high temperature occur, oil inside the oil-containing bearing body leaks out, and part of the oil leaks out from both ends of the oil-containing bearing body after long-term rotation.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes an oil-containing bearing body, a first through hole is arranged on the inner side of the oil-containing bearing body, a guide surface is opened on the inner side of the oil-containing bearing body, a retaining ring is integrally formed at the port of the oil-containing bearing body, an oil storage cavity is arranged between the retaining ring and the port of the oil-containing bearing body, and a second through hole is arranged on the inner side of the port of the oil-containing bearing body.
[0005] Preferably, the inner wall diameter of the first through hole matches the inner wall diameter of the second through hole.
[0006] Preferably, the cross-section of the retaining ring is an L-shaped structure.
[0007] Preferably, the guide surface is an arc-shaped surface structure.
[0008] Preferably, the oil-containing bearing body is a tubular body.
[0009] Preferably, the first through hole and the second through hole are both arranged in a circular shape.
[0010] Compared with the prior art, the beneficial effect of the utility model is that when the oil-containing bearing is in use, the connecting piece rotates, friction and high temperature are generated, and the oil inside the oil-containing bearing body seeps out. If it rotates for a long time, part of the oil will seep out from both ends of the oil-containing bearing body, and the oil will be guided to the inside of the oil storage chamber through the guide surface. By setting the retaining ring, part of the oil can be stored. When the rotation stops, the temperature drops, and the oil stored in the oil storage chamber will be absorbed into the oil-containing bearing body again. In this way, the use of the oil-containing bearing body can be extended and the leakage of oil can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Example
[0018] See also Figure 1-3 The utility model discloses an oil-containing bearing: it comprises an oil-containing bearing body 1, a first through hole 2 is arranged on the inner side of the oil-containing bearing body 1, a guide surface 4 is opened on the inner side of the oil-containing bearing body 1, a retaining ring 5 is integrally formed at the port of the oil-containing bearing body 1, an oil storage chamber 6 is arranged between the retaining ring 5 and the port of the oil-containing bearing body 1, and a second through hole 3 is arranged on the inner side of the port of the oil-containing bearing body 1. When in use, the connecting piece rotates, friction and high temperature occur, and the oil inside the oil-containing bearing body 1 seeps out. When rotating for a long time, part of the oil will seep out from both ends of the oil-containing bearing body 1, and the oil will be guided to the inside of the oil storage chamber 6 through the guide surface 4. By setting the retaining ring 5, part of the oil can be stored. When the rotation stops, the temperature drops, and the oil stored in the oil storage chamber 6 will be absorbed into the oil-containing bearing body 1 again, so that the use of the oil-containing bearing body 1 can be extended and the leakage of oil can be reduced.
[0019] Furthermore, the inner wall diameter of the first through hole 2 matches the inner wall diameter of the second through hole 3 .
[0020] In order to store the oil, the cross section of the retaining ring 5 is set to an L-shaped structure.

If it rotates for a long time, part of the oil will seep out from both ends of the oil-containing bearing body 1, and the oil will be guided to the oil storage chamber 6 through the guide surface 4. Through the setting of the retaining ring 5, part of the oil can be stored. When the rotation stops, the temperature drops, and the oil stored in the oil storage chamber 6 will be absorbed into the oil-containing bearing body 1 again.
