摘要
螺纹连接松动问题一直受到广泛关注。本文对螺纹连接松动问题的研究和技术现状进行了总结。首先总结了螺纹连接松动问题研究工作常用的试验方法,然后从非旋转松动和旋转松动两个方面总结了螺纹连接的松动机理,接着讨论了螺纹连接防松性能的测试与评价方法,以及一些典型防松紧固件的防松原理。最后,本文总结了现有研究中存在的不足,并为未来的研究工作提出了一些新思路。
The problem of threaded connection looseness has been widely concerned.This paper summarizes the research and technical status of threaded connection looseness.Firstly,test methods used in the research of threaded connection looseness are summarized,and the mechanism of threaded connection looseness is summarized from two aspects:non-rotating looseness and rotate looseness.Then,the test and evaluation methods of anti-loosening performance and the anti-loosening principle of some typical fasteners are discussed.Finally,the shortcomings of the existing research are summarized and some new ideas for future research are put forward.
