【摘要】：重要部位结合面螺栓采用冷拉伸长量安装是既保证安装精度又提高安装效率的安装方式,这种方法将逐步取代大螺栓热紧安装方法,延长螺栓使用寿命。文章通过对G324A燃兼压气缸中分面螺栓冷拉伸长试验过程中出现的问题分析以及应力校核,对获得合理的螺栓伸长量的过程进行介绍,对螺栓冷拉安装进行更深的了解。
[Abstract]:The installation of cold drawing elongation is the way to ensure the installation accuracy and improve the installation efficiency. This method will gradually replace the hot tightening installation method of the large bolts and prolong the service life of the bolts. This paper introduces the process of obtaining reasonable bolt elongation by analyzing the problems in the cold tensile elongation test of split face bolts in G324A combustible cylinder and checking the stress, and makes a deeper understanding of the cold drawing installation of bolts.
