Research of application of a new type of connecting and fastening compound nuts in railway turnouts
Bolts are extremely important and commonly used connecting parts for railway lines and bridges,etc.,which may jeopardize the safety of railway operations if they become loose.Focuses on the issue of common connecting nuts that may become loose due to impacts and vibrations,among other reasons,this article designs a new connecting and fastening compound anti-loosening nut which is capable of interlocking.This article also explains the working mechanism of this nut,as well as its composition structure,and analyzes its key technical indicators and points of innovation.After performance testing,hardness testing,and guaranteed load testing,the safety,reliability,anti-loosening,and vibration resistance characteristics of the nut were determined.The results of these tests have shown that the nut has good anti-loosening and vibration resistance,is capable of eliminating looseness and ensuring the safety of connecting fasteners,saves a lot of nut-fastening time,and produces good economic and social benefits,which has a great promotional value.
