Abstract
Provided is a forged material for a rotor for obtaining, by machining, a rotor including a hub portion and a plurality of blade portions. The forged material for a rotor comprises a hub forming section and a plurality of blade forming sections that one-to-one correspond to the plurality of blade portions. The plurality of blade portions each comprise a first end face that faces an outer peripheral surface of the hub portion and a second end face opposite from the first end face. The plurality of blade forming sections each comprise a blade-shaped surface having a shape that follows at least part of a contour of the second end face of the one-to-one corresponding blade portion.
Claims7
A forged material for a rotor of aluminum alloy for obtaining, by machining, a rotor including a hub portion and a plurality of blade portions provided so as to stand on an outer peripheral surface of the hub portion, the forged material comprising:
- a hub forming section, which is a preform of the hub portion;
- and
- a plurality of blade forming sections, which are preforms of the plurality of blade portions and which one-to-one correspond to the plurality of blade portions,
- wherein the plurality of blade portions each comprise a first end face that face's the outer peripheral surface of the hub portion and a second end face opposite from the first end face, and
- wherein the plurality of blade forming sections each comprise a blade-shaped surface having a shape that follows at least part of a contour of the second end face of the one-to-one corresponding blade portion.
A method for manufacturing a rotor, the method comprising:
- a machining step of machining a forged material for a rotor of aluminum alloy for obtaining, by machining, a rotor including a hub portion and a plurality of blade portions provided so as to stand on an outer peripheral surface of the hub portion, the forged material comprising:
- a hub forming section, which is a preform of the hub portion;
- and
- a plurality of blade forming sections, which are preforms of the plurality of blade portions and which one-to-one correspond to the plurality of blade portions,
- wherein the plurality of blade portions each comprise a first end face that faces the outer peripheral surface of the hub portion and a second end face opposite from the first end face, and
- wherein the plurality of blade forming sections each comprise a blade-shaped surface having a shape that follows at least part of a contour of the second end face of the one-to-one corresponding blade portion.
