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. 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 for...
