る。 In the whisker-type composite material 8 whose base material is an aluminum material, the whisker fibers 9 are silicon carbide, carbon, glass, or other inorganic material fibers that do not melt at the temperature of the molten metal used for casting. The material is pressure-formed to a maximum density of about 50%, and molten aluminum material 10 is cast to impregnate the pores of the whisker fibers.
次に上記ロータの製造方法について述べると、

ｂを成形する。 Next, we will discuss the manufacturing method of the above rotor.
The first method is to use a drum-shaped composite material, which will eventually become the left half 1a and right half 1b of the rotor 1, with half made of a whisker-shaped composite material whose base material is the above-mentioned aluminum material, and the other half made of aluminum-based metal. Prepare each material consisting of
A half of a rotor outer peripheral part 3 having a vane groove 2 in a part made of aluminum metal by forging and its interior 6
A hollow part is formed in the whisker-type composite material part, and a shaft 4 and a side part 5 or a shaft 4' and a side part 5' are formed in the part of the whisker-type composite material to form a left half body 1a and a right half body 1 as shown in FIG.
Form b.
そして、左半体１ａと右半体１ｂのロータ外周
部３の端部とを溶接、特に突き合せ溶接や熱間接

を製造する。 In addition, in the second method, a drum-shaped whisker-shaped composite material whose entire base material is aluminum-based material is prepared, which will eventually become the left half 1a and right half 1b of the rotor 1. Similarly, both halves are forged and welded together to form a rotor 1 as shown in FIG.
Manufacture.
尚上記実施例はロータ１の両側にシヤフトを設
けたが、片側に設けてもよいことは勿論である。 In the above embodiment, the shafts were provided on both sides of the rotor 1, but it goes without saying that the shafts may be provided on one side.
本発明は以上のように、ロータ内部を中空にし
たから、中実体のロータに比較し格段と軽量とな
り、またアルミ系材料及びその複合材を用いたか
ら材料的にも軽量化が図れる。 As described above, in the present invention, since the rotor is made hollow, it is much lighter than a solid rotor, and since aluminum-based materials and composite materials thereof are used, the weight can also be reduced in terms of materials.
しかも、ウイスカー繊維による強化と、ロータ
内部を中空にしたことから、中実体に比して剛性
が向上し、また高い強度を必要とするシヤフト部
