小型柴油机曲轴加工工艺探讨

The Probing for Manufacturing Technology of Mini-diesel Crankshaft

柴油机曲轴作为重要运动部件 ,设计要求高 ,在长时间、高速度运转下 ,容易过早地出现失效或断裂现象 ;本文对曲轴表面强化处理、轴向尺寸控制、工艺流程制定、车间布置、键槽位置公差及轴颈平行度保证等生产技术问题的解决 ,强化曲轴生产过程的稳定性和一致性 ,提高了曲轴制造质量。

Diesel crankshaft is an important motion part. It has very tall technical request. The tall speed turn to crankshaft is easy to invalidation and rupture. Manufacturing technology of surface aggrandizement and axial size control and technology flow and plane collocation to workshop and keyway position tolerance and axial parallel tolerance is resolved. It ensures quality and stability and consistency in production.
