    摘要： A turbine bucket includes a shank portion, an adjacent and radially inner dovetail mounting portion, an adjacent and radial outer airfoil portion, with a platform at a radially inner end of said airfoil portion adjacent the shank portion, and an integral cover at a radially outer tip of the airfoil portion, wherein the shank portion is shaped to provide a torque zone establishing a desired torque characteristic for the bucket to create, upon insertion into a dovetail groove on a turbine wheel, a desired contact pressure between the integral cover and adjacent covers in a row of similar buckets.

    摘要： In the diaphragm packing area of a steam turbine, a raised platform affords an annular sealing surface for contact with a brush seal carried by the diaphragm. The platform includes a plurality of platform sealing segments secured to a locking device carried by the rotor. The locking device includes a raised rim having flanges with axially oppositely projecting teeth circumferentially spaced one from the other by slots. The platform segments each include a channel section having flanges with axially inwardly directed teeth. By displacing the platform sealing segments radially inwardly and passing the teeth of the locking device and platform segments through the respective slots, the platform segment teeth lie radially inwardly of the locking device teeth. The platform segments are then rotated radially to align the teeth to secure the sealing surface against radial movement. One segment may be staked, welded or screwed to the locking device to preclude circumferential movement during turbine operation.

    摘要： A steam turbine has a rotor mounting axially spaced rotor wheels having male dovetails for mounting a plurality of axially spaced buckets having female dovetails. A plurality of arcuate bridging members extend axially between the axially adjacent bucket dovetails at locations spaced radially outwardly of the surface of the rotor shaft. A diaphragm in radial opposition to the bridging member mounts a brush seal having bristles engaging the bridging member. The bridging member carries backup labyrinth seal teeth for sealing with the diaphragm. The friction generated by contact between the brush seal bristles and bridging members lies radially outwardly of the rotor whereby non-uniform distribution of heat about the rotor surface due to frictional contact with the brush seal is avoided, with consequent avoidance of rotor bowing.

    摘要翻译： 蒸汽轮机具有转子安装轴向间隔开的转子轮，其具有用于安装多个具有凹形燕尾的轴向间隔开的桶的阳形燕尾。 多个弓形桥接构件在轴向相邻的铲斗燕尾形之间沿与转子轴的表面径向向外间隔开的位置轴向延伸。 与桥接构件径向相对的隔膜安装有具有接合桥接构件的刷毛的刷密封。 桥接构件带有用于与隔膜密封的备用迷宫式密封齿。 由刷子密封刷毛和桥接构件之间的接触产生的摩擦力位于转子的径向外侧，从而避免了由于与刷子密封件的摩擦接触而导致转子表面的不均匀分布，从而避免了转子弯曲。

    摘要： A system and method for generating a smooth blending fillet surface between a platform and an airfoil shape mounted thereto. This is accomplished by generating a fillet surface by acquiring descriptions of an airfoil shape (e.g., the pressure side, the leading edge, the suction side and the trailing edge), a platform surface, a platform footprint, and filleting curves for the pressure and suction sides of the airfoil. These descriptions are used produce a smooth mesh of points which capture both the blending fillet surface and the airfoil. The smooth mesh of points are used to render slope-continuous blended fillet surfaces.

    摘要： A system and method for securing an integral closure bucket to a rotor wheel assembly. The integral closure bucket is inserted in a direction coincident with a radius of the rotor wheel assembly, where the remaining buckets have been previously inserted in a direction parallel to the axis of the turbine rotor wheel. The closure bucket has an integral shroud and is connected to a turbine rotor wheel assembly in which the remaining buckets have been previously inserted in an axial direction. The buckets adjacent the closure bucket are spread apart both tangentially and axially to provide sufficient clearance for the radial insertion of the integral closure bucket. To prevent axial movement of the closure bucket and adjacent buckets, twist locks are utilized in channels provided in the bottom of the female dovetails in the rotor wheel.
