一种复合型线齿轮泵的齿廓反求及分析

Reverse Desing and Analyses of Compound Tooth Profile of Gear Pump

建立了渐开线 -点齿摆线复合齿型的数学模型 ,讨论了该传动的重合度计算 ,并给出了滚齿加工渐开线齿轮的根切曲线方程 ,进而开发了该类传动的计算机辅助设计和分析软件。利用该软件可迅速、灵活地完成该传动的参数设计、性能分析和齿廓绘图 ,生成的齿廓坐标数据和图形文件可直接用于线切割等加工。

In this paper, a mathematical model of invlute point engaging cycloid compound tooth profile is established, the calculation of contact ratio is discussed, the curve equation of root is presented,a software is developed to choose design parameters,analyze performance and draw profile drawing of the gearing. The output coordinates or drawing files can be used for wire cutting directly.
