Abstract
The invention relates to a bearing, in particular to a sparingly soluble bearing of an engine. The sparingly soluble bearing is characterized by comprising a steel back layer, a substrate layer and a sparingly soluble layer which are arranged from outside to inside, wherein the substrate layer is made of aluminum material; and the sparingly soluble layer is made of silicon-iron environment-friendly material. The invention saves energy in the manufacture process, has low cost and can satisfy the technical requirements of the engine, such as high voltage increase, great torque and low emission.
Description
(1) technical field
The present invention relates to a kind of bearing shell, particularly a kind of sparingly soluble bearing of engine.
(2) background technique
The edible bearing shell of existing motor car engine is generally copper lead alloy or aluminum alloy; Though its product has bearing capacity preferably, most alloy materials contain environmental contaminants in various degree, and during engine start; Can cause tile kilning, seize because of lacking lubricant oil; Have an accident, this situation often need remedy through the way that increases electroplating surface, but can cause the higher and environmental pollution of cost thus.
(3) summary of the invention
The present invention provides the sparingly soluble bearing of engine of a kind of environmental protection and energy saving, long service life in order to remedy the deficiency of existing technology.
The present invention realizes through following technological scheme:
A kind of sparingly soluble bearing of engine, its special way is: comprise steel back layer, base layer and slightly soluble layer from outside to inside, wherein, base layer is an aluminium material, and the slightly soluble layer is iron silicon environment-friendly materials.
The present invention adopts the slightly soluble layer to substitute used nickel-barrier layer and the anti-attrition layer of general bearing shell; The inner surface of bearing bush that matches at bearing shell and the diameter of axle; Be that iron silicon environment-friendly materials surface can form one deck slightly soluble layer; Lubricant oil is adsorbed on the slidingsurface of bearing shell, forms one deck oil film reliably, make the friction of the bearing shell and the diameter of axle be tending towards perfect condition; The generation of slightly soluble layer changes simple fatigue resistance of bearing shell and wear resistance, reduces the frictional force of the bearing shell and the diameter of axle to a certain extent, has improved the bearing capacity and the working life of bearing shell.
Consisting of of iron silicon environment-friendly materials according to the invention: Fe 30～38%, Si 60～68%, Al2～4%.Explanation here be that the one-tenth of iron silicon environment-friendly materials is grouped into, in the compositional range that the present invention shows, the microsolubility of iron silicon environment-friendly materials is better.
Base layer thickness according to the invention is 0.05～0.15mm, and the slightly soluble layer thickness is 0.05～0.90mm.Because bearing shell contacts with the diameter of axle; There is certain scope in the thickness of bearing shell itself, and too small its withstand load degree of thickness and antifatigue degree are little, influence its working life; Thickness is excessive then can to cause waste of material; Therefore, in conjunction with the behaviour in service of bearing shell and the effect of base layer and slightly soluble layer, both thickness is limited.
Steel back layer according to the invention, base layer and slightly soluble layer adhere to each other through high temperature sintering.Trilaminate material adheres to each other through high temperature sintering, and Placements such as the welding of its connectivity, bonding are firm and meticulous.
The processing technology of finished product bearing shell also changes during the use of sparingly soluble bearing of engine, and its basic technology is as follows:
The invention has the advantages that:
(1) sparingly soluble bearing of engine key technology, innovation point are that inner surface of bearing bush adopts slightly soluble notion invention design, made one deck slightly soluble layer, rather than adopt the method that improves hardness to improve intensity, increase the service life;
(2) sparingly soluble bearing of engine has adopted engine bearing from original material manufacture, eliminated motor when starting because of lacking inner surface of bearing bush that lubricant oil produces and the dry friction between the diameter of axle.Behind the slightly soluble of bearing shell surface, it is soft that surface layer becomes, and supporting surface increases, and support force is even; Make bearing shell become the most effective, soft relatively surface to the holding state of the diameter of axle, the impurity that is beneficial in promptly having embeds, and is difficult for injuring the diameter of axle; Reduced the requirement to engine oil pressure, compliance is good, tile kilning not during startup; Seize not in the use need not be electroplated, environmental protection fully;
(3) sparingly soluble bearing of engine is not only saved precious metal, and in manufacture process, saved the energy through using iron silicon environment-friendly materials, and is with low cost;
(4) along with the appearance that engine emission is constantly debased the standard require, sparingly soluble bearing of engine material structure of the present invention can satisfy high pressure-charging, high pulling torque, the technical requirements of low emission level engine.
(4) description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a structural representation of the present invention.
Among the figure, 1 steel back layer, 2 base layeres, 3 slightly soluble layers.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises steel back layer 1, base layer 2 and slightly soluble layer 3 from outside to inside, and wherein, base layer 2 is an aluminium material, and slightly soluble layer 3 is iron silicon environment-friendly materials; Consisting of of said iron silicon environment-friendly materials: Fe 30～38%, Si 60～68%, Al2～4%; Said base layer 2 thickness are 0.05～0.15mm, and slightly soluble layer 3 thickness are 0.05～0.90mm; Said steel back layer 1, base layer 2 and slightly soluble layer 3 adhere to each other through high temperature sintering.
When the inner surface of bearing bush that matches with the diameter of axle at bearing shell touches grease; Iron silicon environment-friendly materials can form the slightly soluble layer; Lubricant oil is adsorbed on the slidingsurface of bearing shell; Form one deck oil film reliably, make the tribology of the bearing shell and the diameter of axle be tending towards perfect condition, thereby improve the bearing capacity and the working life of bearing shell.
Behind the inner surface of bearing bush slightly soluble, slightly soluble layer 3 makes the surface become soft, and supporting surface increases; Support force is even, and it is the most effective to make that bearing shell becomes the holding state of the diameter of axle, and the impurity that soft relatively surface also helps in the machine oil embeds; Be difficult for injuring the diameter of axle, prolonged the working life of bearing shell.
