7、对称分流，也采用双层缸结构，内缸为通流部分，外缸为排汽部分。2.转子高中压转子为整锻结构，高压转子由一个单列调节级和九个压力级组成，中压转子由六个压力级组成，低压转子由2×6个压力级组成（双流）也采用整锻结构。高中压转子与低压转子，低压转子与发电机转子均采用刚性连接。3.轴承汽轮机轴承为四点支撑。高中压转子和低压转子分别由1#、2#和3#、4#轴承支撑，4个支持轴承均为带球面轴瓦套的椭圆轴承，整个汽轮发电机组共有10个支持轴承，1￣6#轴承下瓦上设有顶轴油孔。推力轴承为活动可倾瓦块型（即密切尔型），设在2#轴承箱内。4.盘车装置本装置设在低压后轴

8、承箱盖上，采用低速盘车，转速为834.29r/min，当汽轮机转速大于盘车转速时，盘车能自动脱扣，为减少盘车电动机启动力矩，设有顶轴装置
