蒸汽涡轮机转子
摘要：
本发明涉及蒸汽涡轮机转子，具体而言，涉及连接的转子和用于其连接的方法，该转子包括主连接和锁定构件。该主连接包括螺旋地插入形成在相邻转子段中的内螺纹腔(22)的螺纹凸台(12)。通过至少一个锁定元件(35)锁定主连接以防止旋松，该锁定元件(35)部分地位于第一转子段(10)和第二转子段(20)二者中，在径向上或轴向上不完全穿过任何一个转子段(10，20)。此布置使连接能够锁定在最优的扭矩点上。
摘要（英）：

The invention relates to a joined rotor and a method for joining thereof that comprises a primary join and a locking means. The primary join comprises a thread boss (12) that is screwly inserted in a tapped cavity (22) formed in an adjacent rotor section. The primary join is locked, so as to prevent unscrewing, by means of at least one locking member (35) that is located partially in both first (10) and second (20) rotor sections without penetration radially or axially completely through either of the rotor sections (10,20). This arrangements enable the join to be locked at an optimal torque point.
