Description

Technical Field

[0001] The utility model relates to the technical field of mechanical devices, in particular to a high-strength alloy self-lubricating bearing. Background Art

[0002] Self-lubricating bearings are mechanical components that achieve lubrication without the use of external lubricants through their own structure or material properties. They are typically used in applications where lubrication is difficult or impossible, reducing maintenance and increasing equipment reliability and service life. Self-lubricating bearings are primarily based on metal, ceramic, and non-metallic substrates, but copper alloys are the most widely used, due to their high strength and excellent properties, making them widely used in various fields.

[0003] Currently, the most common copper alloy self-lubricating bearings are basically made by drilling multiple holes on the surface of a copper alloy tube, inserting graphite, heating and curing it, and then turning it into a bearing workpiece. However, this traditional bearing structure is basically an integrated bearing workpiece, and its single specification is only suitable for a single working condition and lacks expandable connections. Setting a flange structure at the end will increase the external diameter of the bearing, making it very inconvenient to use. Utility Model Content

[0007] Preferably, there are a plurality of graphite through holes, and the graphite through holes are equidistantly distributed around the tube wall of the copper alloy self-lubricating bearing tube body.

[0008] Preferably, one end of the graphite filling block close to the inner wall of the copper alloy self-lubricating bearing tube body coincides with the curvature of its inner wall arc surface, and one end of the graphite filling block close to the outer ring wall of the copper alloy self-lubricating bearing tube body coincides with the curvature of its outer wall arc surface.

[0009] Preferably, the rubber gasket is made of fluororubber, and the rubber gasket is fitted to the inner wall of the connecting ring groove.

[0010] Preferably, the ring diameter and thickness of the connecting edge ring match the ring diameter and thickness of the connecting edge ring groove, and the inner concave thread groove is adapted to the outer convex thread.

[0011] Preferably, both end edges of the copper alloy self-lubricating bearing tube body are provided with chamfers, and the chamfer depth of the edge of one end of the copper alloy self-lubricating bearing tube body close to the connecting edge ring is greater than that of the other end.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This high-strength alloy self-lubricating bearing is achieved by respectively arranging matching connecting edge ring grooves and connecting edge rings at both ends of the copper alloy self-lubricating bearing tube body of the entire bearing workpiece body, and the connecting edge ring grooves and connecting edge rings are both located in the middle of the end edge of the copper alloy self-lubricating bearing tube body to avoid interference with the outer diameter and inner diameter space of the copper alloy self-lubricating bearing tube body, so that two workpieces can be assembled by connecting the connecting edge ring grooves and the connecting edge rings to form bearing workpieces with different length specifications, without increasing the external diameter of the bearing and without occupying the internal space of the bearing. The application has very good expandability and improved flexibility in application. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting ring groove 4 is provided in the middle of the edge of the end of the copper alloy self-lubricating bearing tube body 1 away from the connecting ring 7, a rubber lining ring 5 is bonded to the end wall of the connecting ring groove 4, and an inner concave thread groove 6 is provided along the outer ring wall of the connecting ring groove 4.

[0021] In the present invention, there are multiple graphite through holes 2, and the multiple graphite through holes 2 are evenly distributed around the tube wall of the copper alloy self-lubricating bearing tube body 1;

[0022] More specifically, a plurality of graphite through holes 2 are equidistantly distributed around the wall of the copper alloy self-lubricating bearing tube body 1 to ensure the lubrication quality of the bearing.

[0023] In the present invention, one end of the graphite filling block 3 close to the inner wall of the copper alloy self-lubricating bearing tube body 1 coincides with the arc of the inner wall, and one end of the graphite filling block 3 close to the outer ring wall of the copper alloy self-lubricating bearing tube body 1 coincides with the arc of the outer wall;

[0024] More specifically, the two ends of the graphite filling block 3 are arranged to coincide with the arcs of the inner and outer rings of the copper alloy self-lubricating bearing tube body 1, thereby ensuring the stability of the lubrication provided by the bearing.

[0025] In the present invention, the rubber gasket 5 is made of fluororubber, and the rubber gasket 5 is attached to the inner wall of the connecting ring groove 4;

[0026] More specifically, by using fluororubber to make the rubber gasket 5, its structure is more stable and its long service life is guaranteed.
