Self-fastening type lubricating bearing plate

Abstract

The invention discloses a self-fastening type lubricating bearing plate, which comprises a lubricating copper powder layer, a steel plate layer, an epoxy structural adhesive layer, a fluorine-layer-containing polyimide film layer, a thermal conductive rubber layer, a heat dissipation layer and a zinc oxide layer. The heat dissipation layer comprises porous fiber and aerogel; and the porous fiber is located in the aerogel. The porous fiber comprises perforated fiber and a porous fiber glue layer. The porous fiber glue layer is positioned on that outer surface of the perforated fiber. A graphene layer structure is arranged in the pores of the porous fiber glue layer. The lubricating copper powder layer, the steel plate layer, the epoxy structural adhesive layer, the fluorine-layer-containing polyimide film layer, the thermal conductive rubber layer, the heat dissipation layer and the zinc oxide layer are sequentially arranged. On the steel plate layer, a groove is arranged on a first winding side edge, a bulge is arranged on a second winding side edge, and powder adhesive layers are arranged on the outer surfaces of the first winding side edge and the second winding side edge; while improving the excellent heat dissipation performance of a self-lubricating bearing, the bending effect can be exerted.

Description

technical field [0001] The invention belongs to the technical field of bearing production, and in particular relates to a self-buckle lubricating 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.

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

In addition, whether the existing bearing sleeves are used for low-speed or medium-high speed applications, the coil sleeves are welded by welding, and the bonding force is firm, but the cost of the coil sleeves will be increased and welding will affect the materials near the weld seam.
