美制螺纹量规设计执行国标的可行性分析

Analysis on the US Based Screw Thread Gauges and National Standards of China

通过对美国联邦螺纹标准H28中FED—STD—H28/6《统一螺纹的量规和测量》和我国相应的国家标准GB3934《普通螺纹量规》在螺纹量规的分类、功能、特征、螺纹合格性判断及螺纹量规的中径公差等方面进行比较、分析,可得出结论:检验美制工件螺纹用的美制螺纹量规执行国家标准具有可行性和优越性,能满足美制工件螺纹极限尺寸的检验条件,适当延长量规使用寿命以及适合我国螺纹量规制造水平.

Compared to US Screw Tread Standards H28 and the Relative National Standards of China in classification, functions, features, qualifications and pitch dianeter tolerator, it is possible and advantageous to carry out the National standards of China by uaing US Screw TreadCauges, because the National Standards of China has met the checking requirements and been able to increase the lifetime of screw thread.
