摘要： A process to mitigate stress corrosion cracking (SCC) in pinned root fixings of axial flow steam turbine rotor discs made of a low alloy. Such pinned root fixings 30 comprise pins 303 running axially through bores 305 in inter-digitated (interleaved) blade root fingers 141 ( Fig. 1 ) and disc fingers 301. The process includes at least the steps of:
(i) increasing the value of the ratio b/M by an amount in the range of about 0.4 to about 0.6, where b is the axial breadth of the disc fingers 301and M is the sum of b and the axial breadth G of the gap between adjacent disc fingers, thereby to obtain an increase in the breadth b of the disc fingers and a corresponding reduction in the breadth G of the gap between adjacent disc fingers;
(ii) reducing the breadth of the blade fingers to match the reduction in the breadth G of the gap between adjacent disc fingers; and
(iii) judiciously increasing the diameter D of the pins and the bores in a row of bores 305 in the disc fingers, thereby reducing peak stress in the disc fingers 301.

摘要： A steam turbine blade having a high degree of strength reliability that reduces the stress caused by a steam force acting on a steam turbine blade during the operation of a steam turbine and increases rigidity in the circumferential and axial directions of a turbine rotor (8) to suppress vibration of the steam turbine blade resulting from the steam force.
A steam turbine blade includes a blade (3); a shroud (1) attached to a tip of the blade; a blade root (5) projecting toward the radial inner circumferential side of a turbine rotor (8) so as to be fitted into a blade groove (6) provided in an outer circumferential portion of a turbine rotor; and a platform (4) disposed between the blade (3) and the blade root (5). The blade root is inserted into the blade groove (6) along the axial direction of the turbine rotor (8). The blade (3), the shroud (1), the blade root (5) and the platform (4) are integrally molded. The number of the blade roots (5) is larger than that of the blades (3).

摘要： A closure bucket group (100) for mounting on a dovetail (140) of a turbine wheel (150). The closure bucket group (100) may include a leading bucket (110) with a leading bucket rear side (170), a closure bucket (120) with a closure bucket front side (230) and a closure bucket rear side (240), and a trailing bucket (130) with a trailing bucket front side (320). The leading bucket rear side (170) and the closure bucket front side (230) define a pair of first enclosed keyways (390) and the closure bucket rear side (240) and the trailing bucket front side (320) define a pair of second enclosed keyways (400). A number of keys (410, 420, 430, 440) may be positioned within the first enclosed keyways (390) and the second enclosed keyways (400).
