Introduction

Ring groove rivets were invented in the United States in the 1940s and have been widely used worldwide due to their excellent performance. 19 In the 1980s, it began to be used in the domestic aviation field. In the 1890s, the former Ministry of Railways began to use a large number of ring grooves in rail transit equipment. Rivets and localization. After decades of development, ring groove rivets have been successfully applied to railway vehicles, mining machinery, automobiles, heavy trucks, ships. In the fields of ship, aerospace, steel structure, etc., it has the characteristics of convenient installation, quickness, excellent anti-loose performance, excellent fatigue life and maintenance-free. Head Front, ring groove rivets and installation tools are generally used in the British series design, and a large number of use, and China's national fastener standards are all metric Series, in order to adapt to the actual situation of production and use, in this standard, 5.8R, 8.8R class I ring groove rivet connection pair and type II ring groove rivet connection The nominal diameter of the joint is converted from the inch series to the metric series; the 10.9R high-strength ring groove rivet connection pair independently developed by China Use the metric series. See Table 1 for the comparison of nominal diameter, inch diameter and metric diameter of 5.8R and 8.8R type I ring groove rivets and type II ring groove rivets.
