Abstract
The invention discloses a high-hardness abrasion-resistant bush which comprises a substrate made of a copper-based alloy. The copper-based alloy comprises the following components in percentage by weight: 67-81 percent of copper, 15-25 percent of nickel, 3-7 percent of tin, 0.5-1.2 percent of zinc, 0.05-0.20 percent of lead, 0.05-0.25 percent of manganese and the balance of inevitable impurities. By adopting the materials, the bush has lessened abrasion in adverse production environment, prolonged service life, reduced replacement number of a bearing, improved production efficiency and decreased cost. The invention has the advantages of less abrasion and long service life.
Description
Technical field
The present invention relates to a kind of bearing shell.
Background technique
The fin tube milling train is because the defective of work under bad environment and lubricated cooling aspect is used for the performance requirement that the bearing between cutter hub and the cutter shaft need have high abrasion, high hardness.It is main raw material(s) that plain bushing adopts tin bronze (Qsn10-1), is difficult to satisfy wear-resisting and requirement hardness; The external normal Babbitt (Zchsnsb11-6) that adopts, its abrasion resistance is better than tin bronze, but costs an arm and a leg; These material common drawback are that hardness is not high, are not suitable as the bush material of bearing between fin tube milling train cutter hub and the cutter shaft.
Summary of the invention
Technical problem to be solved by this invention provide a kind of wearing and tearing in abominable production environment less, long high-hardness abrasion-resistant bush of life-span.
For solving the problems of the technologies described above, technological scheme of the present invention is: high-hardness abrasion-resistant bush, comprise matrix, the material of described matrix is a copper base alloy, described copper base alloy comprises following component by weight percentage: 67%～81% copper, 15%～25% nickel, 3%～7% tin, 0.5%～1.2% zinc, 0.05%～0.20% lead, 0.05%～0.25% manganese, all the other are unavoidable impurities.
As optimized technical scheme, described copper base alloy comprises following component by weight percentage: 72.60% copper, 20.98% nickel, 5.24% tin, 0.80% zinc, 0.13% lead, 0.15% manganese, all the other are unavoidable impurities.
Owing to adopted technique scheme, high-hardness abrasion-resistant bush, comprise matrix, the material of described matrix is a copper base alloy, described copper base alloy comprises following component by weight percentage: 67%～81% copper, 15%～25% nickel, 3%～7% tin, 0.5%～1.2% zinc, 0.05%～0.20% lead, 0.05%～0.25% manganese, all the other are unavoidable impurities.Owing to adopted above-mentioned material, the wearing and tearing of bearing shell in abominable production environment reduce, and have prolonged the working life of bearing shell, have reduced the replacing number of times of bearing, have improved manufacturing efficiency, have reduced cost.The present invention have wearing and tearing less, long advantage of life-span.
