在国家标准GB3934-83《普通螺纹量规》一书中,没有给出通止端螺纹塞规中径与螺纹环规中径磨损极限尺寸的计算公式,这样不便于进行具体尺寸计算,不便于校对通止端螺纹塞规中径与螺纹环规中径是否磨损超差,所以有必要给出它们的磨损极限尺寸计算公式来,叙述如下: 一、通止端螺纹塞规中径磨损极限尺寸的计算由GB3934-83《普通螺纹量规》一书中的螺纹塞规中径公差带图可知:
In the national standard GB3934-83 “ordinary thread gauge,” a book, there is no end-to-end thread gauge diameter and thread ring diameter diameter wear limit size of the formula, so inconvenient to calculate the specific size is not easy to proofread Through the end of the thread plug gauge diameter and diameter of the thread ring diameter wear ultra poor, so it is necessary to give their wear limit size calculation formula, described as follows: First, through the end of the plug gauge diameter wear limit size Calculated by the GB3934-83 “ordinary thread gauge” in a book thread gauge diameter tolerance chart shows:
