Abstract
The invention relates to a high performance bushing, which is used for engine. Nickel grid layer of the high performance bushing is equipped with two-layer binary alloy frication-reducing layer. The bushing of the present invention has good corrosion resistance, good abrasion resistance, high fatigue resistant strength and no pollution to environment, and can be widely used for motor vehicle engine.
Description
Technical field
The utility model relates to the motor bearing shell, relates in particular to the high-performance bearing shell that motor car engine is used.
Background technique
Bearing shell should have bigger bearing capacity and fatigue strength, should have good seizure resistance, allowing property of embedding, compliance, corrosion resistance and compressive strength simultaneously.Along with diesel engine at a high speed, carry direction by force and develop, the alloy bearing shell obtains use more and more widely.Existing alloy bearing shell is made up of base layer, nickel-barrier layer and the anti-attrition layer of steel backing, copper lead alloy on structural type, and wherein base layer is arranged on the steel backing, and nickel-barrier layer is plated on the base layer, and anti-attrition layer is plated on the nickel-barrier layer.Anti-attrition layer generally adopts slicker solder copper (PbSnCu) ternary alloy.This bearing shell can satisfy the basic demand of motor to a certain extent, but is applied on the reinforcement internal-combustion engine of Motor Vehicle, and the fatigue resistance of bearing shell, corrosion resistance and wear resistance all have much room for improvement.
Summary of the invention
The purpose of this utility model is: a kind of have good corrosion resistance, wear resistance is good, fatigue resistance is high high-performance and environmental protection bearing shell are provided.
Technical solution of the present utility model is: the nickel-barrier layer of high-performance bearing shell is provided with two-layer binary alloy anti-attrition layer.
Above-described anti-attrition layer can be nickeltin layer and gun-metal layer (NiSn+SnCu).
Nickeltin layer of the present utility model can be located on the gun-metal layer.
Gun-metal layer of the present utility model can be located on the nickeltin layer.
The utility model has the advantages that because anti-attrition layer is two-layer binary alloy layer, the fatigue strength of anti-attrition layer improves greatly, up to (recording) more than the 130MPa with the sapphire fatigue test board, and the anti-attrition layer of existing bearing shell adopts copper tin copper ternary alloy, and its fatigue strength (records with the sapphire fatigue test board) about 63MPa.Because the fatigue resistance of anti-attrition layer of the present utility model is improved, thereby improved the fatigue resistance of bearing shell greatly.The corrosion resistance and the wearability of anti-attrition layer also improve simultaneously, and the corrosion resistance of bearing shell and wearability are strengthened.And can not pollute environment.
Description of drawings
Fig. 1 is an organigram of the present utility model.
Among the figure: 1-steel back layer, 2---base layer, 3---nickel-barrier layer, 4---anti-attrition layer
Embodiment
Shown in figure one, the utility model comprises the base layer 2 that steel back layer 1 and copper lead alloy are made.Described base layer 2 is arranged on the steel back layer 1, and the copper lead alloy layer can or be sintered on the steel back layer 1 by casting as base layer 2.Plate one deck nickel-barrier layer 3 on the base layer 2, electroplate two-layer binary alloy anti-attrition layer 4 on the nickel-barrier layer 3.Described anti-attrition layer 4 is made of (NiSn+SnCu) nickeltin layer 41 and gun-metal layer 42.Nickeltin layer 41 casting or sintering also can be with 42 casting of gun-metal layer or sintering on nickeltin layers 41 on gun-metal layer 42.Structure, the performance comparison of the utility model and comparative example see Table 1.
Table 1: the structure of the utility model and comparative example, performance comparison:
The fatigue resistance of anti-attrition layer material adopts " sapphire fatigue test board " test in the table 1.Two-layer binary alloy anti-attrition layer (NiSn+SnCu) alloy is as anti-attrition layer material of the present utility model, and its fatigue resistance is when 130MPa tests, and product is normal.
Corrosion resistance adopts " medicinal white oils " test in the table 1, and the corrosion resistance of two-layer binary alloy anti-attrition layer material of the present utility model is than the good corrosion resistance of the ternary alloy anti-attrition layer material of Comparative Examples bearing shell.
Wearability adopts " wear testing machine " contrast test.
