一、前言目前我国小模数齿轮还没有国标,执行的是机标JB305—67。机标的体制和公差数值基本上是以苏联59标准为蓝本编制而成的,它已经不能满足我国当前工业日益发展的要求,因此迫切需要编制出符合我国当前生产状况的国标体制,以促进我国工业的不断发展。国标中的公差计算式是国标体制中的主要组成部分,因为公差数值表是由公差计算式推算出来的。但是如何编制公差计算式,国内没有这种资料,国外资料也没有作详细介绍的,因此,这对我国来说还是一个新课题。遵照毛主席关于“独立自主,自力更生”、及“走自己
I. Introduction At present, China’s small module gear has not GB, the implementation of the machine standard JB305-67. The system and tolerance values of the standard are basically compiled based on the standard of the Soviet Union 59. It can no longer meet the current requirements for the development of the industry in our country. Therefore, it is imperative to compile a national standard system that is in line with the current production conditions in our country so as to promote the industrialization of our country The continuous development. The tolerance calculation formula in the national standard is the main part of the national standard system because the tolerance value table is calculated by the tolerance calculation formula. However, how to formulate the formula for calculating the allowances, there is no such information in China and no detailed information on foreign materials. Therefore, this is still a new issue for our country. Following Chairman Mao’s principle of “independence, self-reliance,” and “walking oneself.”
