Embedded bearing with solid lubricant

Abstract

The invention relates to an embedded bearing with a solid lubricant, and belongs to the technical field of machinery. The problem that the tensile strength and elongation of an embedded bearing with a solid lubricant in the prior art cannot simultaneously meet requirements is solved. The embedded bearing with the solid lubricant comprises a barrel-shaped substrate made from an alloy material, wherein lubricating holes are formed in the inner and outer walls of the substrate; a solid lubricating material is arranged in the lubricating holes; the alloy material is prepared from the following components by weight: 60 to 66 percent of Cu, 23 to 26 percent of Zn, 5 to 8 percent of Al, 2 to 7 percent of Fe and 1 to 2 percent of Ni. According to the embedded bearing with the solid lubricant, the substrate is made from the alloy material, so that the substrate simultaneously has strong tensile strength and high elongation; in addition, the lubricating holes are formed in the substrate, and the solid lubricating material is filled in the lubricating holes, so that the lubricating performance of the substrate can be improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a bearing during mechanical movement, in particular to a solid lubricating bearing. Background technique [0002] Self-lubricating bearings are loaded by a metal matrix, and a special formula of solid lubricating material acts as a lubricant. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for occasions where it is difficult to lubricate and form an oil film such as heavy load, low speed, reciprocating or swinging, and is not afraid of water flushing and other acid corrosion. and scour. It has been widely used in metallurgical continuous casting machines, steel rolling equipment, mining machinery, molds, hoisting machinery, textile machinery, wind power generation, ships, steam turbines, water turbines, injection molding machines and equipment production lines. ...

AI Technical Summary

Problems solved by technology

[0003] Solid lubricating bearings made of national standard ZCuZn25A16Fe3Mn3 material, tensile strength ≥ 740N / mm 2 , elongation ≥ 7%, can not meet high-strength working conditions

Based on other materials developed by it, the tensile strength is ≥810N / mm 2 , elongation ≥ 10%, the elongation has increased, but the tensile strength still cannot meet the high-strength working conditions

Based on the IGF052 material developed by it, the tensile strength is ≥850N / mm 2 , elongation ≥ 2%, the tensile strength can meet the high-strength working conditions, but the elongation has not reached the national standard, indicating that the toughness of the material is very poor

Tensile strength and elongation are inversely proportional to each other. It is difficult to meet the requirements of elongation and tensile strength in high-strength working conditions.
