三峡电站水轮发电机转子支架直径为16.5m,采用圆盘式新结构,重量高达2100t,与传统结构不同,水电机组整个旋转部分的重量不是通过卡环作用在发电机主轴上,而是通过推力头支承由转子支架中心体的下圆盘支承,即从水轮机主轴传递来的轴向水推力,转子重量以及发电机主轴的重量等全都都施加圆盘的把合螺钉上,从而对转子中心体形
The turbine support rotor of the Three Gorges hydropower station has a diameter of 16.5m and adopts a disc-type new structure with a weight of up to 2100t. Unlike the traditional structure, the weight of the entire rotating part of the hydropower unit does not act on the generator shaft through the snap ring but passes The thrust head support is supported by the lower disk of the rotor support center body, that is, the axial water thrust force transmitted from the turbine main shaft, the weight of the rotor, and the weight of the generator main shaft are all applied to the disk clamping screw, Body shape
