Problems solved by technology

The structural strength of copper powder metallurgy is relatively low, it is difficult to adapt to high-load working conditions, and it is easy to cause strain during the running-in period
The use of polymer protection on the back of the steel plate can improve the life of self-lubricating bearings, but it brings heat dissipation problems
The inventor disclosed a heat dissipation plate before, which improves the heat dissipation effect of the plate, and uses copper particles to solve the problem of the bonding force between the fluorine material and the steel plate, but this structure brings some problems. For example, the copper particles mainly use physical effects to stabilize the fluorine material. The most important thing is that when sintering copper particles to the steel plate, it will have a great impact on the lubricating copper powder, because the performance of the lubricating copper powder is the core of the bearing plate, so the lubricating copper powder must be sintered first, and then the copper is sintered after it passes the inspection Particles, which will cause secondary sintering of lubricating copper powder, affect lubricating performance, and increase and reduce yield

Embodiment 1

[0018] See attached Figure 1-3 , Self-lubricating heat-dissipating bearing plate includes lubricating copper powder layer 1, steel plate layer 2, epoxy structural adhesive layer 3, fluorine-containing layer polyimide film layer 4, thermal conductive adhesive layer 5, heat dissipation layer 6, zinc oxide layer 7; heat dissipation Layer comprises porous fiber 8, airgel 9; Porous fiber is located in airgel; Porous fiber comprises porous fiber 10, porous fiber adhesive layer 11; Porous fiber adhesive layer is positioned at the outer surface of porous fiber; The hole of porous fiber adhesive layer There is a graphene layer structure 12; a lubricating copper powder layer, a steel plate layer, an epoxy structural adhesive layer, a fluorine-containing polyimide film layer, a thermally conductive adhesive layer, a heat dissipation layer, and a zinc oxide layer are arranged in sequence, wherein the polyimide One side 41 of the amine film (12.5 μm) is in contact with the epoxy structura...

Embodiment 2

[0026] On the basis of Example 1, a release film layer is provided outside the zinc oxide layer to protect the zinc oxide layer during curling and protect the shaft sleeve during transportation. After the shaft sleeve is installed on the existing bracket, tear off the release film The film layer can be used routinely; in actual production, it is found that there is no crack in the zinc oxide layer after the plate containing the release film layer is rolled into a shaft sleeve, and there is no scratch on the shaft sleeve during transportation. Relatively speaking, if there is no release film layer , The machine inspection found that there were about 6 ten thousandths of cracks in the zinc oxide layer during the winding process, and there were also scratches during the transportation process. The release film is a commercially available product, and it only needs to be tightly attached to the outside of the zinc oxide layer. Those skilled in the art can easily understand that the...

Description

technical field [0001] The invention belongs to the technical field of bearing production, and in particular relates to a self-lubricating and heat-dissipating bearing plate. Background technique [0002] Self-lubricating bearings have begun to receive attention because they are suitable for places where lubrication is unreliable or impossible. Single-material self-lubricating bearings generally have two structures: copper powder metallurgy and plastic. The structural strength of copper powder metallurgy is relatively low, it is difficult to be suitable for high-load working conditions, and it is easy to cause strain during the running-in period. The use of polymer protection on the back of the steel plate can improve the life of the self-lubricating bearing, but it brings about the problem of heat dissipation. The inventor disclosed a heat dissipation plate before, which improves the heat dissipation effect of the plate, and uses copper particles to solve the problem of t...
