Due to the impact of the material internal stress, a mid-split surface stagger and inner diameter roundness out-of-tolerance occurred after machining of the tilting-pad bearing, therefore the bearing pad clearance were not consistent after assembly. Through analyzing the deformation causes and adjusting the machining procedures and machining allowance for many times, the machining deformation problem is properly solved which not only satisfies the roundness tolerance requirements but also guarantees the pad clearance consistency of the tilting-pad bearing after assembly.
