Centrifugal compressor, a manufacturing method of a turbocharger and centrifugal compressor comprising a centrifugal compressor

Also in the axial direction of the mounting hole away and the sleeve portion and the clamp surface, shrinkage fitting has been centrifugal compressor axial force is ensured to be added to the sleeve portion from the impeller, the turbocharger and said with a centrifugal compressor an object to provide a method for manufacturing a centrifugal compressor, the inner circumferential surface of the mounting hole formed in the hub includes a clamping surface and diverging surface, the outer peripheral surface of the sleeve portion includes a reduced diameter surface. Diverging surface and reduced diameter surface has mutually abutting impeller-side contact portion and the sleeve-side contact part, respectively, from the axis of the mounting hole in the radial direction of the mounting hole until the sleeve abutting portion length is d, the length from the sleeve abutting portion in the axial direction of the mounting hole until the clamping surface is L, and the axis of the generatrix of the sleeve portion of the virtual cone relative to reduced diameter surface contact with the sleeve abutting portion There when the angle intersecting the sleeve inclination angle [theta] s, the following equation: [theta] s
