Research of the Model of the Deviation Measurement and Accuracy Standard Establishment of the Ellipse Family Gear

Abstract

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.
