摘要： The invention relates to an inner housing hub (24, 58) for a gas turbine (1). The inner housing hub (58) can be arranged in the gas turbine (1) about a gas turbine shaft and is formed as a component of an inner housing (56). The inner housing hub together with the inner housing (56) is used to deflect hot gases exiting combustion chambers towards a turbine inlet region (54) arranged in the direction of the gas turbine shaft. The inner housing hub comprises at least one substantially cylinder casing-shaped securing portion (28) comprising a cylinder casing-shaped main part (30), which comprises a hot side (34) facing a hot gas path (32) and a cold side (36) facing away from the hot gas path. At least one web-shaped protrusion (38) extends along the cold side (36) and is arranged on the cold side on the main part (30) in order to secure the inner housing hub (24, 58). The inner housing hub according to the invention is subject to reduced wear. For this purpose, the web-shaped protrusion (38) consists of a first material and the main part (30) consists of a second material, the first material having a greater thermal expansion coefficient than the second material so that the thermally induced stresses are reduced in the region of the securing portion (28) in at least one operating state of the gas turbine (24) in comparison to an integral main part/web-shaped protrusion design consisting of the second material.
摘要翻译：内部壳体毂围绕燃气涡轮机轴布置在燃气涡轮机中，并且形成为用于将离开燃烧室的热气体朝向沿着燃气涡轮机轴的方向布置的涡轮机入口区域偏转的内部壳体的部件。内部壳体毂包括至少一个基本上为圆柱形的壳体形状的固定部分，其具有气缸壳体形状的主要部分，其具有面向热气体路径的热侧和背离热气体路径的冷侧。至少一个腹板形突起沿着冷侧延伸并且布置在主要部分的冷侧上，以便固定内部壳体毂。网状突起由第一材料制成，主要部分由第二材料制成，第一材料具有比第二材料更大的热膨胀系数。

摘要： A gas turbine (1) comprising a plurality of coaxial components disposed one inside the other and designed substantially in the form of hollow cones or hollow cylinders, and comprising a guide vane support (16), is intended to enable an especially high efficiency while maintaining the greatest possible operating safety and operating life. To this end, at least one of the components or the guide vane support has a substantially elliptical cross-sectional contour.
