Abstract
The present invention relates to technical field of automobile parts more particularly to a kind of engine cams.Requirement with consumer to car mass is higher and higher, and as critical component, simple conventional material is increasingly difficult to meet the requirement in terms of the service life engine cam.The present invention is by being bonded metal layer and wear-resistant layer with adhesive layer, metal layer generates higher intensity by rational proportion elemental composition, wear-resistant layer uses wear-resistant material, so that the wearability and intensity of engine cam all greatly improve, effectively extends the service life of engine cam.Present invention is mainly used for engine cams.
Description
Technical field
The present invention relates to technical field of automobile parts more particularly to a kind of engine cams.
Background technique
In the manufacturing field of auto parts and components, steel and aluminium are widely applied as main material.As consumer is to automobile
The requirement of quality is higher and higher, and as critical component, simple conventional material is increasingly difficult to meet in the service life engine cam
The requirement of aspect.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of using composite material and the hair good with wearability
Motivation camshaft.
Technical scheme is as follows:
A kind of engine cam, including metal layer, adhesive layer and wear-resistant layer；Engine cam is arranged in metal layer
The outside of metal layer is arranged in inside, adhesive layer, and the outside of adhesive layer is arranged in wear-resistant layer；The chemical composition and quality of metal layer
Percentage are as follows: nickel 0.65-0.89%, manganese 0.61-0.17%, phosphorus≤0.04%, aluminium 0.007-0.083%, sulphur≤0.03%, carbon
0.24-0.26%, chromium 0.07-0.8% and titanium 0.05-0.07%, remaining content are iron.
Further, the material of wear-resistant layer is 99 porcelain.
Further, wear-resistant layer with a thickness of 0.5-1.0mm.
Further, adhesive layer is inorganic oxide copper product.
The beneficial effects of the present invention are:
By the way that metal layer and wear-resistant layer are bonded with adhesive layer, metal layer is generated higher by rational proportion elemental composition
Intensity, wear-resistant layer use wear-resistant material, so that the wearability and intensity of engine cam all greatly improve, effectively extend
The service life of engine cam.
Specific embodiment
With reference to embodiment, the embodiment of the present invention is furthur described in detail.Following embodiment is used for
Illustrate the present invention, but is not intended to limit the scope of the invention.
A preferred embodiment of the invention, the engine cam, including metal layer, adhesive layer and wear-resistant layer；Metal
The inside of engine cam is arranged in layer, and the outside of metal layer is arranged in adhesive layer, and the outside of adhesive layer is arranged in wear-resistant layer；
The chemical composition and mass percent of metal layer are as follows: nickel 0.65-0.89%, manganese 0.61-0.17%, phosphorus≤0.04%, aluminium
0.007-0.083%, sulphur≤0.03%, carbon 0.24-0.26%, chromium 0.07-0.8% and titanium 0.05-0.07%, remaining content are
Iron, the material of wear-resistant layer are 99 porcelain, wear-resistant layer with a thickness of 0.5-1.0mm, adhesive layer is inorganic oxide copper product.
The above is only the preferred embodiment of the present invention, are not intended to restrict the invention, it is noted that this technology is led
For the those of ordinary skill in domain, without departing from the technical principles of the invention, several improvements and modifications can also be made,
These improvements and modifications also should be regarded as protection scope of the present invention.
