Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a composite sliding bearing. Background Art

[0002] Composite plain bearings are special bearings that combine the advantages of different materials to improve overall performance and durability. These bearings are usually composed of a metal base and one or more layers of special materials (such as plastics, ceramics or metal alloys) that can provide self-lubricating, wear-resistant, and anti-friction properties.

[0003] When the outer ring of the bearing is subjected to force, it will be squeezed with the steel balls. Under continuous force, the outer ring of the bearing is prone to deformation. At the same time, the steel balls act on the inner ring, causing the inner ring to deform as well. This deformation may even cause the bearing to be scrapped. The inner hole of the bearing becomes larger due to wear, making it extremely inconvenient to disassemble and replace. Utility Model Content

The outer arc surface of the inner convex strip 403 is movably overlapped with an L-shaped shaft member 5, and an extension end is provided on one side of the L-shaped shaft member 5. The extension end of one side of the L-shaped shaft member 5 is placed on the bearing surface 401, and the outer arc surface of the retaining ring 4 is movably connected with a rubber ring 6, and the inner arc surface of the rubber ring 6 is movably connected to one side of the inner convex strip 403.

[0023] The retaining ring 4 is pressed inwardly through the rubber ring 6, and the retaining ring 4 is tightly fitted on the inner wall of the bearing outer sleeve 1 and the bearing inner sleeve 2 through the cooperation of the outer convex strip 402 and the inner convex strip 403, so that the bearing outer sleeve 1 and the bearing inner sleeve 2 are kept in close contact with each other to ensure the sealing effect, provide pre-tightening force for the close contact between the bearing outer sleeve 1 and the bearing inner sleeve 2, and maintain a good sealing effect.

[0024] A groove 601 is provided on the inner arc surface of the rubber ring 6, and the inner arc surface of the groove 601 is movably overlapped with the surface of the bearing surface 401. The inner arc surface of the L-shaped shaft member 5 is movably overlapped with the rubber ring 6. There are two L-shaped shaft members 5, which are distributed on the surface of the retaining ring 4 in a mirror-symmetrical manner. The outer conical surfaces 302 on both sides of the elastic bearing 3 are movably clamped to the surface of the bearing inner sleeve 2. A ball member is movably connected in the arc groove between the bearing outer sleeve 1 and the bearing inner sleeve 2. There are several elastic gaps 301 on the outer arc surface of the elastic bearing 3, which are evenly distributed in the form of a circular array.
