曲轴校直工艺分析

Technology analysis of engine crankshaft straightening

本文重点分析了曲轴弯曲的原因,围绕两种校直工艺——压力校直和滚压校直在球墨铸铁曲轴生产上的应用,进行试验研究,为球墨铸铁曲轴采用校直工艺生产,取得了理论依据,并在大批量生产中得到验证。

This article mainly analyzes the cause of crankshaft bending. In order to get the theory basis for the production of nodular cast iron crankshaft with straightening technology, research and tests have been taken for the both kinds of straightening technology-Bench straightening and Roller straightening. The theory is validated in a large scale production.
