(1)本文从齿轮磨床“传动链精度分析”中得出影响工件精度与机床主要零件精度的关系方程,提出从理论分析来指导检修实践的尝试,以探讨机床磨损与机床精度的关系。(2)本文具体地介绍了齿轮磨床各种主要零件的修复方法(包括需用的专用工具图纸),系上海工具厂、南京机床厂及上海机床厂等检修经验的总结。 (1) In this paper, the relationship equation between workpiece accuracy and the precision of the main parts of the machine tool is derived from the “Gear Chain Accuracy Analysis” of the gear grinding machine, and an attempt to guide the maintenance practice from the theoretical analysis is put forward to discuss the relationship between the machine wear and the machine accuracy. (2) This text concretely introduced the repair method of all kinds of main parts of gear grinder (including the special tool drawings needed), which is the summary of overhaul experience of Shanghai tool factory, Nanjing machine tool factory and Shanghai machine tool factory.
