大型轴类零件冷装技术探讨

Search a Cold Fitting Technology of Large Shaft Parts

近年来,机械工程中采用大型轴类零件的过盈连接技术越来越普遍,因此有必要对大型轴类零件的过盈装配技术进行探索。文章针对大型轴类零件大过盈量的特点,结合实践,通过计算冷却参数和设计工艺装备,探索出一种有别于传统的冷装技术——剂量控制冷却技术。该技术改变了传统的浸泡冷却技术,具有设备投资少、成本低等特点。

The interference connection of large shaft parts has become more and more common in mechanical engineering. It is necessary to search the large-scale shaft parts Interference Fitting technology. Based on a large amount of large-scale shaft paris, combined with practice, different from the traditional cold fitting technology by calculating the cooling parameters and design of process equipment, the paper searches a dose-controlled cooling technology. The new cooling technology has changed the traditional immersion cooling technology, with less investment in equipment, and low cost.
