Abstract: A steam turbine nozzle airfoil with integral inner and outer sidewalls is engaged with an inner ring and an outer ring in a nozzle assembly. Previous designs required large clearances between radial surfaces to permit simultaneous circumferential loading of the inner and outer sidewall into the inner and outer rings. The inventive arrangement provides for breech loading of the inner sidewall into the inner ring which allows near line-to-line radial contact on the hooks between the rings and the integral sidewalls of the Singlet nozzle airfoil. Tighter radial clearance overcome problems with loose assembly such as movement during welding, gaps leading to stress risers and performance issues associated with nozzle throat control.
Abstract translation: 具有整体内壁和外侧壁的汽轮机喷嘴翼型件与喷嘴组件中的内环和外环接合。 以前的设计需要径向表面之间的大间隙，以允许内侧壁和外侧壁同时周向地加载到内圈和外圈中。 本发明的装置提供了内侧壁进入内环的后膛加载，其允许在环之间的钩和单列喷嘴翼型的整体侧壁之间的近线对线的径向接触。 更紧密的径向间隙克服了松动组装的问题，例如焊接过程中的移动，导致应力梯度的间隙和与喷嘴喉部控制相关的性能问题。

Abstract: A steam turbine singlet nozzle airfoil with integral outer sidewall is engaged with an inner ring and an outer ring in a nozzle assembly. The interface of the outer sidewall with the outer ring may include a plurality of mechanical hooks on one or both of the upstream face and the outer radial face of the outer sidewall that engage with complimentary structures on the outer ring. The outer interface may further include low energy welds along limited distances of one or both of the upstream or downstream interface of the outer sidewall and the outer ring. An inner radial end of the singlet nozzle airfoil is pinned into position and fastened to the inner ring. Without a need for high heat welds, distortion of the airfoil and the steam flow path and the associated rework is eliminated and stage performance is improved.
Abstract translation: 具有整体外侧壁的蒸汽轮机单线喷嘴翼型件与喷嘴组件中的内环和外环接合。 外侧壁与外环的界面可以包括在外侧壁的上游面和外径向面中的一个或两个上与外环上的互补结构接合的多个机械钩。 外界面还可以包括沿着外侧壁和外环的上游或下游界面中的一个或两个的有限距离的低能量焊缝。 单列喷嘴翼型的内径向端部被固定到位并紧固到内圈。 不需要高热焊接，消除了翼型件和蒸汽流动路径的变形以及相关的返工，并且提高了工作台性能。
