“传动链精度计算方法”广泛应用于重要减增速装置，航天、天文仪器、精密雷达、机床等传动链设计及制造质量的分析上。国内工程应用中传动链精度计算方法的各种各样和不统一，影响有关产品的质量的提高和在国际市场上的竞争能力。下面就几种国内外较典型的算法（统计法）进行对比分析，并介绍传动链精度计算方法有关国家标准的制订情况。
“Transmission Chain Accuracy Calculation Method” is widely used in the design and manufacturing quality analysis of drivetrain such as important deceleration devices, aerospace, astronomical instruments, precision radar and machine tools. Domestic engineering applications in the accuracy of transmission chain calculation methods vary and do not affect the improvement of the quality of the products and competitiveness in the international market. Here are some of the more typical algorithms at home and abroad (statistical method) for comparative analysis, and introduced the accuracy of the calculation method of the chain of national standards for the development of the situation.
