汽轮发电机轴及联轴器属于高精密机械加工产品，它们的机械加工性能直接决定机组轴系运行的稳定性和安全性。对于已经存在的由于制造、检修、运行等诸多因素导致的联轴器销孔偏斜、失圆、磨损等缺陷，采用扩孔、过盈镶套，并通过有限元方法进行应力校核是一种比较可行的工艺。

As the steam turbine generator shaft and coupling are high-precision machinery processing products, their machi-ning performance directly determines the stability and security of the shaft system operation. To the existing coupling pin de-fects which were mainly due to many factors in manufacturing, maintenance and operating, such as deflection, out of round and wear, it is found that using methods of chambering and interference bushing, and checking stress through the finite ele-ment method is a more feasible process.
