み合せて、溶接などにより一体にしたものなどがある。b. Prior art FIG. 1 shows an example of a camshaft used in a valve mechanism of an automobile engine, in which a is a cam portion and b is a journal portion. Such camshafts include those that are integrally formed by casting, and those that are made by combining component parts that have been individually formed by forging and welding them together.
また、−木の金属管を用い、これをバルジ成形によって

ジャーナル部などを同時に成形する方法などが知られて
いる。A method is known in which the journal portion and the like are molded at the same time.
Ｃ０発明が解決しようとする問題点
前記の方法により製造されるカムシャフトのうち、鋳鉄
（ねずみ鋳鉄、 Ｆｅ１２など）によって鋳造されるも
のは、鉄の比重が大きいため、その総重量が重くなると
いう問題点がある。そのため、第２図に示すように内部
を一部中空化したものが実用化されているが、必ずしも
充分な軽量化は計られていない。Problems to be solved by the C0 invention Among the camshafts manufactured by the above method, those cast from cast iron (gray cast iron, Fe12, etc.) have a large specific gravity, so the total weight is heavy. There is a problem. For this reason, as shown in FIG. 2, a device with a partially hollow interior has been put into practical use, but this has not necessarily resulted in sufficient weight reduction.
一方、軽量化の目的でアルミナ焼結体によるセラミック
ス・カムシャフトが考えられるが、セラミックス焼結体
で作成した摺動面の表面層には、焼結体自身の有する気
孔率が１％程度で、潤滑油の保持部となるべき四部がほ
とんどなく、実際には使用できないという問題点がある
。また、アルミナの特質として摺動面近傍においては、
アルミナの分子構造中に水酸基（−Ｏｆ＋）が形成され
ていて、親油性でないため、潤滑油の保持能力が橿めて
劣るという問題点がある。On the other hand, a ceramic camshaft made of alumina sintered body may be considered for the purpose of weight reduction, but the surface layer of the sliding surface made of ceramic sintered body has a porosity of about 1%. However, there is a problem in that there are almost no parts that should serve as lubricating oil holding parts, so it cannot be used in practice. In addition, as a characteristic of alumina, near the sliding surface,
A hydroxyl group (-Of+) is formed in the molecular structure of alumina, and since it is not lipophilic, there is a problem that the ability to retain lubricating oil is significantly inferior.
本発明は前記事情に鑑みてなされたもので、前記従来技
術の問題点を解消してなるアルミニウム合金製カムシャ
フトを提供しようとするものである。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an aluminum alloy camshaft which eliminates the problems of the prior art.
ｄ、 問題点を解決するための手段
本発明は前記問題点を解決するため、カムシャフトをア
ルミニウム合金で製作し、その表面に分散メッキを施す
ようにしたものである。d. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is such that the camshaft is made of an aluminum alloy and its surface is coated with dispersion plating.
以下、本発明について図面を参照しながら詳細に説明す
る。Hereinafter, the present invention will be explained in detail with reference to the drawings.
本発明に係るカムシャフトは、第１図に示すような中実
構造とし、これをアルミニウム合金、またはその鋳物に
よって製作するものである。The camshaft according to the present invention has a solid structure as shown in FIG. 1, and is manufactured from an aluminum alloy or a casting thereof.
用いられるアルミニウム合金は、従来のカムシャフトと
同等の機械的強度かえられる組成のものであればよく、

とえばＡＣ４Ｃ−７６）を用いることによって、はぼ同
等の機械的強度のものかえられ、かつ鋳造性、加工性に
ついても問題のないことが判った。The aluminum alloy used only needs to have a composition that provides mechanical strength equivalent to that of conventional camshafts.
For example, in contrast to a camshaft with a minimum wall thickness of four dragons that has a hollow structure made using conventional cast iron (such as Fe12), an aluminum alloy casting of the same shape and solid structure (such as AC4C-76) is used. As a result, it was found that the material had almost the same mechanical strength as the original material, and there were no problems in terms of castability and workability.
次に前記アルミニウム合金鋳物（ＡＣ４Ｃ−７６）によ

なわち、分散メッキを施すことによって従来のカムシャ
フトと性能的にほとんど変わらず、しかも軽量化された
本発明のカムシャフトを完成したのである。Next, although the camshaft made of the aluminum alloy casting (AC4C-76) has good mechanical strength, its surface hardness is approximately 90 on Brinell hardness, and this is used as is for a camshaft with a sliding surface. There is a problem. Therefore, the inventors of the present invention applied a special wear-resistant surface treatment layer to the surface of a camshaft made of aluminum alloy casting, that is, applied dispersion plating to the surface of the camshaft. The lightweight camshaft of the present invention was completed.

This is a surface treatment layer that performs its functions.

C-76), and when an N1-P-SiC dispersed coating film is applied to the surface of the hard fine particles, for example, using SiC as a dispersion material, the N1-P matrix itself can...
The micro-Vickers hardness is around 700 (Hmν), which is equivalent to or higher than the conventional Fe12 camshaft. Moreover, since SiC particles are eutectoid in the N1-P-SiC dispersion plating film, these SiC particles can withstand constant contact resistance with the opposing rocker arm as the camshaft rotates. It exhibits wear resistance, reinforces the hardness of the camshaft surface, and continues to maintain it, so there is no wear on the cam surface.

This coating exhibits lubricity, making the rocker arm slide extremely smoothly as the camshaft rotates.
