摘　　要：将具有椭圆曲线特征的非圆齿轮归纳为椭圆族齿轮,探讨节曲线特性,并总结通用数学模型。在深入分析圆柱齿轮、锥齿轮、小模数齿轮精度标准的基础上,结合椭圆族齿轮特性拟定椭圆族齿轮精度标准,拟定单项偏差项目与综合偏差项目、推导5级精度计算公式、划分精度等级并初步确定级间比。对齿轮的啮合测量方法进行总结,在此基础上研究椭圆族齿轮全啮合测量模型,为椭圆族齿轮精度评价体系的建立、偏差项的有效测量以及齿轮工业的多元发展提供了思路。The non - circular gears which have the characteristics of the ellipse is induced to elliptical family gear, the curve characteristics are discussed and the general mathematical model is summarized. On the basis of in - depth analysis of cylindrical gear, bevel gear and small module gear accuracy standard, combining with the characteristics of elliptical family gear, its accuracy standard, single deviation items and comprehensive deviation item are formulated, the 5 grades accuracy calculation formula is deduced, the accuracy grade is divided, the grade proportion is initially determined. On the basis of the summarizing of gear meshing measurement methods, the comprehensive meshing measurement model of elliptical family gear is researched, a train of thought for the accuracy evaluation system establishment and the deviation item effective measurement of elliptical family gear and the diversified development of gear industry is provided.
