間を必要としていた。However, in the former manufacturing method, it is difficult to make the wall thickness of the metal component constant, and after the material is cast, the inner peripheral portion and the outer peripheral portion are cut to form the shape. Had to be modified, which required a lot of man-hours and time to manufacture.

時間がかかるという問題があった。In the latter method, during the shrink fitting process,
It requires many work steps and time such as cutting, heating and fitting materials. Especially when manufacturing metal parts by shrink fitting using three or more kinds of dissimilar metals, it takes a lot of man-hours and time. There was a problem of this.

を形成するように構成される。To this end, in the manufacturing method of the present invention, the molten metal is poured into the mold while rotating the mold rotatably supported about the horizontal center axis. Due to the centrifugal force that accompanies the rotation of the molten metal, the molten metal is formed along the inner peripheral surface of the mold to form a metal layer.Furthermore, while rotating the mold, the molten metal of the dissimilar metal is injected into the metal layer inside the mold. The molten metal is attached to the inner peripheral surface of the metal layer by a centrifugal force caused by the rotation of the poured molten metal to form a dissimilar metal layer on the inner surface of the metal layer.

By force, the molten metal is made to follow the inner peripheral surface of the mold to form a metal layer. To make the molten metal flow evenly on the inner surface of the mold,
Since an acceleration of 40 G to 50 G is suitable for the molten metal, when the inner diameter of the mold is 100 mm, the rotation speed of the mold is 840 to 950 rpm.

The molten metal injected into the metal layer uniformly adheres to the inner peripheral surface of the metal layer due to the centrifugal force associated with the rotation thereof, and forms a dissimilar metal layer on the inner peripheral portion. The solidification of the molten metal progresses from the outer circumference to the inner circumference, the dissimilar metal layer and the outer metal layer are bonded well, and the dissimilar metal layer having a predetermined thickness is formed inside.
