摘要： A gas turbine engine disk that includes a centrally disposed disk hub having an integrally-formed, radially outwardly extending web terminating at an outer end. The disk hub has a radially-displaced annular hub surface exposed to high pressure, high temperature discharge gases during engine operation. The radially-displaced annular hub surface acts as an axial free surface mitigating the formation undesirable axial stress in the disk hub.

摘要： A gas turbine section of a gas turbine engine, including a first stage turbine disk, a forward outer seal carried on the turbine disk. and a forward shaft cooperating with the first stage turbine disk for transmitting torque generated by the turbine section to a compressor section of the engine. The forward shaft intersects the first stage turbine disk at a non-perpendicular angle in the area of the disk hub for directing sufficient hot air against the disk hub to balance the thermal response rate of the disk hub to the thermal expansion rate of the forward outer seal.

摘要： A welding method that enables the joining of at least two dissimilar, metallic alloys to form a weld that is free of cracks is disclosed. The method incorporates a pure (99.00% minimum by weight) nickel fill-wire, integrally assembled into the joint between the two alloyed metals to be joined. The alloys joined by this method are an iron-based, low expansivity, gamma-prime strengthened superalloy (i.e., Incoloy®) and a high carbon, powder metallurgical tool steel high in refractory metal alloying agents (i.e., CPM REX 20). Welding of the joint results in the formation of a nickel rich region within the weld, thus “inoculating” the weld against cracks. The weld joint formed by the method of the present invention can be used in the fabrication of a rotating anode bearing shaft assembly for use in an x-ray generating device.
摘要翻译：公开了一种焊接方法，其能够连接至少两种不同的金属合金以形成没有裂纹的焊缝。该方法包含纯（99.00％最小重量）镍填充线，整体组装到要接合的两种合金金属之间的接头中。通过这种方法接合的合金是一种铁基低膨胀性的γ-强化超级合金（即Incoloy）和一种高耐火金属合金剂（即CPM REX 20）的高碳粉末冶金工具钢，。接头的焊接导致在焊缝内形成富镍区域，从而“焊接”焊缝以防止裂缝。通过本发明的方法形成的焊接接头可用于制造用于x射线产生装置的旋转阳极轴承轴组件。

摘要： A first stage turbine disk section for a gas turbine engine, including a centrally disposed disk hub having an integrally-formed, radially outwardly extending web terminating at an outer end. The disk hub has a convex, curved hub surface exposed to high pressure, high temperature compressor bleed and discharge gases during engine operation, and the convex, curved hub surface acts to reduce the axial constraint at the location of peak axial stress, thereby mitigating the formation of undesirable axial stress in the disk hub and allows separation of the peak axial and hoop stresses, thereby reducing the magnitude of the peak hub surface effective stress.
