马格磨齿机液性胀胎心轴的精度分析

Accuracy Analysis on Hydraulic Expansion Mandrel of MAAG Gear Grinder

本文从应力变形的角度分析了液性胀胎心轴受力后外径不能复原的原因和所采取的修复措施,以阻止变形的延续,保证进口机床正常运转.

At the viewpoint of stress deformation, the paper analyses the reason why the outer diameter of hydraulic expansion mandrels can not be recovered after being stressed. Appropriate restoring measures are taken it to prevent it from continuous deforming.
