Problems solved by technology

It has the characteristics of low friction coefficient, high efficiency and wear resistance, but because the single-layer carbon fiber fabric is relatively thin, in order to achieve sufficient thickness, it needs to be paved in multiple layers. Defects such as time length and complicated process control

Abstract

The invention relates to a half-bearing, a material, a device and a method for a steel backing / carbon fiber knitted fabric self-lubricating lining. According to the invention, the half-bearing for the steel backing lining is made by arranging a polymer self-lubricating composite material lining (1) reinforced by a layer of knit carbon fiber on the inner surface of the steel backing (2); the half-bearing lining material adopts epoxy resin as substrate and carbon fiber knitted fabric as a reinforced body, short carbon fiber is added as a secondary reinforced body, and various modification, filling and self-lubricating ingredients are added. Carbon fiber knitted fabric is used as the reinforced body for the half-bearing to increase the shear strength, the impact strength and the compression strength of the lining material; the advantages of high bearing capacity, good impact resistance, low friction coefficient, good dynamic performance and wear resistance are obtained; the mold pressing forming technology is simplified, and the operation difficulty is reduced; steel is used to replace copper to save expensive metal; lead is not used, so that the environment is protected; the inner surface of the half-bearing is made through net shape forming, so that the geometric dimension is high in stability; the recycling and reusing are convenient.
