Abstract
The invention discloses an engine bearing bush made of alloy composite materials, which comprises an antifriction layer, wherein the antifriction layer is composed of the following components in percentage by weight: 0.05-1% of nickel, 1-5% of graphite, 0.3-0.5% of zinc, 2-10% of tin, 1-5% of bismuth, 0.1-0.5% of lead, 0.1-1.5% of aluminum oxide and the balance of copper. Tests in salt spray chambers show that the engine bearing bush is superior to the traditional lead-tin-copper alloy coating; and since the materials are used, the bearing bush has less abrasion in a severe production environment, thus prolonging the service life of the bearing bush, reducing the replacement frequency of a bearing, improving the production efficiency and lowering the cost. The engine bearing bush has the advantages of less abrasion and long service life.
Description
Technical field
The present invention relates to a kind of automobile engine bearing, relate in particular to a kind of alloy composite materials engine bearing.
Background technique
Traditional copper alloy bearing-bush obtains applying very widely at present on the high-mechanic internal-combustion engine, it is comprised of base layer, nickel-barrier layer and the anti-attrition layer of a steel back layer, a Cuprum alloy on structural type, wherein base becomes on steel back layer, nickel-barrier layer is plated on base layer, and anti-attrition layer is plated on nickel-barrier layer.Anti-attrition layer generally adopts the Amounts of Lead, Tin Copper ternary alloy, wherein lead content is up to 80～90%, this bearing shell can meet the basic demand of motor to a certain extent, but be applied on the internal-combustion engine of strengthening, because the fatigue resistance degree of anti-attrition layer is low, can not meet the car combustion engine development need, the fatigue resistance of bearing shell, corrosion resistance and wear resistance all have much room for improvement.Owing to containing plumbous grade for harmful metal elements in bearing shell, bearing shell can not be ignored the impact of environmental disruption simultaneously, necessary production environment protection type bearing shell, thus meet social development need.
Summary of the invention
?the deficiency existed for prior art, technical problem to be solved by this invention is, a kind of with low cost, reasonable mixture ratio is provided, has the alloy composite materials engine bearing that bearing capacity is high, wear-resisting, corrosion-resistant and a kind of alloy composite materials environmental protection forms.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of alloy composite materials engine bearing, comprise anti-attrition layer, described anti-attrition layer is comprised of the composition of following weight percentage: nickel: 0.08～1%, and graphite: 2～5%, zinc: 0.5～0.8%, tin: 5～10%, vanadium: 5～8%, lead: 0.1～0.5%, bismuth: 1%～15%, surplus is copper.
Above-mentioned alloy composite materials engine bearing, comprise anti-attrition layer, and described anti-attrition layer is comprised of the composition of following weight percentage: nickel: 0.5%, and graphite: 3%, zinc: 0.5%, tin: 7%, vanadium: 6%, lead: 0.3%, bismuth: 10%, surplus is copper.
The advantage of alloy composite materials engine bearing of the present invention is: through salt spray test chamber, test, be better than traditional lead-tin-copper alloy coating, owing to having adopted above-mentioned material, the wearing and tearing of bearing shell in severe production environment reduce, extend the working life of bearing shell, reduced the replacing number of times of bearing, improved manufacturing efficiency, reduced cost, the present invention have advantages of wearing and tearing less, the life-span is long.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further details;
