摘要： A plurality of turbine buckets annularly arranged around a rotor are each provided with a ledge disposed at right angles to the outer surface of each bucket. Each ledge includes a leading end portion and a trailing end portion each formed therein with a vertical hole, leading and trailing end portions of the ledge of each turbine bucket extending in opposite directions on both sides of the bucket. There are provided cover pieces each interposed between ends of the adjacent two turbine buckets and formed on the upper surface with a plurality or cylindrical projections adapted to be loosely received in the vertical holes formed in the ledges of the adjacent two turbine buckets. Contact surfaces adapted to be brought into contact with the undersides of the ledges are formed on the upper surface of each cover piece and interposed between the cylindrical projections, and an upper end portion of at least one of the cylindrical projections is machined to provide an enlarged diameter projection portion so as to preclude dislodging of the projection from the hole whereby the cover piece can positively connect the adjacent two buckets together.
摘要翻译：围绕转子环形布置的多个涡轮机桶分别设置有与每个铲斗的外表面成直角设置的凸缘。每个凸缘包括前端部分和后端部分，每个前端部分和后端部分均形成有垂直孔，每个涡轮机的凸缘的前端部分和后端部分在桶的两侧沿相反方向延伸。设置有各自设置在相邻的两个涡轮叶片的端部之间的盖片，并且在上表面上形成有多个或圆柱形突起，其适于松动地容纳在形成在相邻的两个涡轮机叶片的壁架中的竖直孔中。在每个盖件的上表面上形成适于与凸缘的下侧接触的接触表面，并且插入到圆柱形突起之间，并且至少一个圆柱形突起的上端部分被加工以提供扩大的以防止突起从孔中移出，由此盖件可以将相邻的两个水桶正确地连接在一起。

摘要： The annular array of radially extending blades on the rotor of a rotary fluid machine are tied together at generally their mid portions by interlocking separate tying members and projection pairs, wherein each projection pair includes facing projections on adjacent blades of the array. The tying members and projections have mating bearing surfaces that will provide a tangential force as a result of wedging produced by the centrifugal force acting upon the tying members during rotation of the rotor at rated speed, without restraining individual twisting of the blades about their radial extent.
摘要翻译：旋转流体机械的转子上的径向延伸的叶片的环形阵列通常通过互锁的单独的捆扎构件和突起对而被连接在一起，其中每个突起对包括在阵列的相邻叶片上的面对突起。绑定构件和突起具有配合的轴承表面，其将由于在转子以额定速度旋转期间作用在结合构件上的离心力产生的楔形结果而提供切向力，而不会限制叶片围绕其径向范围的单独扭转。

摘要： A turbo machine rotor assembly which includes a turbine wheel having moving blade covers or connecting pieces connected to adjacent moving turbine blades. Each of the moving turbine blades includes a first ledge and second ledge at a leading edge and trailing edge side portions, respectively, of the tip of the blade with the first and second ledge portions extending substantially in tangential directions of the turbine wheel but in opposite directions to each other. One of the first and second ledges is provided with a through hole or aperture extending radially of the turbine wheel. The moving blade cover or connecting piece is provided with a pair of spaced pins receivable in the apertures of the first and second ledges for connecting the first ledge of one moving turbine blade and the second ledge of an adjacent moving turbine blade in such a manner that the upper surface of the cover contacts with the lower surfaces of the first and second ledges. One of the pins is loosely fitted in one aperture and the other pin is provided with a flared head portion for rotatably fixing the connecting piece between adjacent turbine blades. The moving blade cover can bear a large centrifuged force and does not constrain the torsions of the moving turbine blades during the rotation of the turbine wheel.
