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。
