概述国标及航标《小模数齿轮及其传动公差》中,均明确指出:双面啮合综合测量(简称双啮)是现代小模数齿轮成批生产中控制齿轮精度及侧隙的最佳检验方法。并明文规定:对一般常用的齿轮推荐优先选用双啮检验。“标准齿轮”是开展齿轮双啮检验必备的标准元件,它是测量齿轮的基准。在精密仪器和仪表制造工业中,现在广泛采用了m=0．15的小模数齿轮。多年来,由于国内尚无一家生产m=0．15的小模数标准齿轮,致使该规格的齿轮不能广泛地采用双啮检验。为贯彻新标准,尽快对m=0．15的小模数
Overview GB and Aids “small module gear and its transmission tolerance” are clearly pointed out: double-sided meshing integrated measurement (referred to as double rocket) is a modern small module gear production batch control gear accuracy and backlash the best test method. And expressly provides: the preferred gear for the common choice of double-ching test. “Standard gear” is to carry out the gear double rodent test standard components, it is the basis for measuring gear. In the precision instrumentation and instrumentation industry, small module gears of m = 0.15 are now widely used. Over the years, as there is no domestic production of a small modulus m = 0.15 standard gear, resulting in the specifications of the gear can not be widely used double-ching test. To implement the new standard, as soon as possible on the m = 0.15 small modulus
