ないという問題があつた。(Prior Art) The inventor of the present application proposed a rotor consisting of a hollow main body, both side plates welded to both sides of the main body, and a rotating shaft provided on one or both of the both side plates (Japanese Patent Application No. 58 −28611). Although the weight of the rotary fluid pump has been reduced to some extent with the proposed rotor, in order to further reduce the weight, it is necessary to use a light metal as the material for the rotor body and to make the wall thickness as thin as possible. However, if light metal is used, the wall thickness cannot be made that thin due to strength issues. On the other hand, when iron-based materials such as steel are used, the wall thickness can be made thinner than in the case of light metals, but there is a problem in that the weight is not significantly reduced.

As shown in FIGS. 1 and 2, the rotor body 12 of the rotor 10 is formed in a hollow shape, and side plates 13 and 14 formed by press molding or forging are welded to both sides of the rotor body. The rotating shaft 11 is forged integrally with the side plate 14, or is manufactured separately and welded to the side plate 14.

溶接してロータとする。 As shown in FIG. 3, the rotor body 12 is made of whiskers F made of inorganic materials such as silicon carbide, carbon, and glass, and base metals made of ferrous materials such as steel or light metal materials such as aluminum, aluminum alloys, and magnesium alloys. It is a composite material made of M. The whiskers are pressure molded to have a porosity of at least 50% and placed in a mold in which rotor body 12 is cast. A molten metal of the base metal M is injected into the mold and infiltrated into the voids of the whiskers F to form a composite material consisting of the whiskers F and the base metal M. Then, the rotor body 12 is manufactured by forging the composite material. Since the base metal M of the rotor body 12 is reinforced with whiskers F, which are ultra-high strength fibers, the wall thickness can be made thinner than that of conventional rotor bodies, and the weight is therefore significantly reduced. A rotor is prepared by welding a side plate on which a rotating shaft is previously provided to the rotor body manufactured in this way.

ロータ本体１２の比強度は一層増大する。 To explain the forging process, the whiskers are pressurized so that about 50% porosity remains and are placed in a forging die, and molten base metal is poured into the die. The molten metal is infiltrated into the whisker voids to form the rotor body material, which is then forged to form the hollow rotor. In the rotor body 12 manufactured by forging, as shown in FIG. 4, the whiskers F in the base metal M are aligned along the grain flow line.
The specific strength of the rotor body 12 is further increased.
