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。通过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,强化了曲轴生产过程的稳定性和一致性,使曲轴制造质量得到提高。
Diesel engine crankshaft as an important moving parts, high design requirements, in a long time, high-speed operation, prone to failure or fracture premature phenomenon. Through the crankshaft surface hardening, axial size control, process development, workshop layout, keyway position tolerance and journal parallelism to ensure the production of technical problems such as the solution, and strengthen the stability and consistency of the crankshaft production process, the crankshaft manufacturing Quality is improved.
