摘要： A device for connecting the turbine blades of a turbine having a plate-shaped member provided at the radially outer end of each turbine blade and extended substantially at a right angle to the longitudinal plane of the turbine blade. The plate-shaped member is projected from the leading and trailing edges of the turbine blade, and is provided with through bores formed in each projected portion. Connecting members having cylindrical pins or the like projections are disposed between two adjacent turbine blades in such a manner that the projections are rotatably received by respective through bores. Namely, one of the connecting members is connected to the plate-shaped member of the leading edge of the turbine blade while the other connecting member is connected to the plate-shaped member of the trailing edge of the preceding adjacent turbine blade. The connecting members are disposed such that they partially underlie the plate-shaped members of the adjacent turbine blades and that they make contact with each other during the running of the turbine thereby to restrict the untwisting of the turbine blades while attaining a vibration damping effect.
摘要翻译：一种用于连接涡轮机的涡轮叶片的装置，其具有设置在每个涡轮机叶片的径向外端处并基本上与涡轮叶片的纵向平面成直角延伸的板状构件。板状构件从涡轮叶片的前缘和后缘突出，并且在每个突出部分中设置有通孔。具有圆柱形销或类似突起的连接构件以这样的方式设置在两个相邻的涡轮叶片之间，使得突起可旋转地被相应的通孔接收。也就是说，其中一个连接构件连接到涡轮叶片的前缘的板状构件，而另一个连接构件连接到前一相邻涡轮叶片的后缘的板状构件。连接构件被布置成使得它们部分地位于相邻涡轮叶片的板状构件的下面，并且在涡轮机的运行期间它们彼此接触，从而限制涡轮叶片的解捻，同时获得减振效果。
