Zusammenfassung:	To provide an airfoil shroud assembly including a tenon with an externally threaded stud for coupling airfoil shrouds to an airfoil in a turbomachine.SOLUTION: An airfoil and shroud (120) assembly includes an airfoil including a root end (118), a free end (128) and a tenon (150) extending from the free end (128), the tenon (150) including a base (124) and an externally threaded stud (154) extending from the base (124). The shroud (120) includes an opening (156) configured to receive the base (124) of the tenon (150). A nut (170) is configured to be threadably coupled to the externally threaded stud (154) on the tenon (150) on the airfoil to couple the shroud (120) to the airfoil.SELECTED DRAWING: Figure 2 【課題】ターボ機械において翼形部シュラウドを翼形部に結合するための雄ねじ付きスタッドを有するほぞを含む翼形部シュラウドアセンブリを提供する。【解決手段】翼形部とシュラウド（１２０）のアセンブリは、根元端部（１１８）、自由端部（１２８）、および自由端部（１２８）から延在するほぞ（１５０）を含む翼形部を含み、ほぞ（１５０）は、基部（１２４）と、基部（１２４）から延在する雄ねじ付きスタッド（１５４）と、を含む。シュラウド（１２０）は、ほぞ（１５０）の基部（１２４）を受け入れるように構成された開口部（１５６）を含む。ナット（１７０）は、シュラウド（１２０）を翼形部に結合するために、翼形部上のほぞ（１５０）の雄ねじ付きスタッド（１５４）に螺合するように構成される。【選択図】図２
