けるインペラの構造。[Claims for Utility Model Registration] Full-wing blades and half-wing blades are provided alternately on the outer peripheral surface of a substantially truncated conical boss portion along a direction twisted with respect to the central axis and inclined in the circumferential direction. ,
The length of the full-wing blade in the axial direction is longer than the length of the half-wing blade in the axial direction, and the twist angle of the full-wing blade and the half-wing blade with respect to the central axis is from the middle part to one end side. In an impeller in a turbocharger having different parts, a first blade that traverses the flying blades so as to separate from other parts a part of the flying blades in which the angle of twist is approximately equal to the angle of twist in the half blades.
one of the half-wing blades so as to pass through the boss portion surface between the full-wing blade and the half-wing blade continuously with the first parting line and to separate the half-wing blade from the full-wing blade. An impeller structure for a turbocharger, characterized in that it is divided into at least two parts in the axial direction by a second dividing line that detours around the end side, and the divided parts are joined and integrated.
