钳式吊车空心轴轴向定位螺纹防松结构改进

Improving Axial Positioning Locking Thread on the Hollow Shaft of the Dogging Crane

本文通过对现场使用的几种螺纹联接的防松结构进行可靠性对比,分析了螺纹联接件松脱失效原理并改进为凹凸双螺母磨擦防松结构。

This article hereof will make a comparison for reliability through several kind of check—structure of thead—connection used on the site,and also here points out the unlock principle of the screw—coherence parts and modifies this to friction check—structure of concavo—convex double nut
