摘要： A rotating electrical machine is provided in which, even when torque from a water turbine is reduced and reverse torque is applied due to load cut off, a rotor core is not eccentric to spider arms. The rotor of a rotating machine includes a vertical rotating shaft, spider arms extending radially from the vertical rotating shaft, and a rotor core component provided to the outer circumference of the spider arms. A T key and cotters are inserted into and secured to a key way provided to an abutment surface of the inner circumference of the rotor core component and the top end of the spider arm. A plate spring is mounted to a surface of the spider arm, the surface facing a rotational direction for electrical generation. The plate spring has one side engaging the spider arm, the other side engaging the rotor core component, and a middle portion bolted from an opposite surface of the spider arm.

摘要翻译： 提供一种旋转电机，其中即使当来自水力涡轮机的扭矩减小并且由于负载切断而施加反向扭矩时，转子铁心也不会偏心到蜘蛛臂。 旋转机械的转子包括垂直旋转轴，从垂直旋转轴径向延伸的星形臂以及设置在星形轮臂的外周的转子芯部件。 将T键和键销插入并固定到设置在转子芯部件的内周边和星形轮臂的顶端的邻接表面上的键槽中。 板簧安装在支臂的表面上，该表面面向用于发电的旋转方向。 该板簧具有一个与所述星形轮臂接合的侧面，另一个侧面与所述转子芯部件接合，并且一个中间部分从所述星形轮臂的相对表面上螺栓连接。
