Abstract
A disc of a rotating machine according to the present disclosure includes: an inner diameter-side member configured to have an annular shape centered on an axis line, to form a portion on a radial inner side with respect to the axis line, and to be formed of a first material having relatively high density and relatively high stiffness; and an outer diameter-side member configured to be joined to a radial outer side of the inner diameter-side member, and to be formed of a second material having relatively low density and relatively high stiffness.
Claims7
A disc of a rotating machine comprising:
- an inner diameter-side member that has an annular shape centered on an axis line, that forms a portion of the disc on a radial inner side relative to the axis line, and that is formed of a first material having relatively high density and relatively high stiffness in the disc;
- and
- an outer diameter-side member that is joined to a radial outer side with respect to the inner diameter-side member, and that is formed of a second material having relatively low density and relatively high stiffness in the disc.
A disc of a rotating machine comprising:
- an inner diameter-side member that has an annular shape centered on an axis line, that forms a portion of the disc on a radial inner side relative to the axis line, and that is formed of a third material having relatively low density and relatively low stiffness in the disc;
- and
- an outer diameter-side member that forms a portion of the disc on a radial outer side, and that is formed of a fourth material having relatively high density and relatively high stiffness in the disc.
