内啮合摆线齿轮泵摆线轮齿廓参数化设计分析

Parameter Design and Anlaysis of Internal Meshing Cyclodial Gear Pump

利用齿轮啮合原理推导出了摆线齿轮的齿廓曲线方程,讨论了两种齿根过渡曲线的处理方法,并利用Visual Basic 6.0在AutoCAD平台上实现了齿轮完整齿廓曲线的参数化绘制,这对于进一步分析齿轮的啮合特性及力学性能具有重要的意义。

Internal meshing cycloidal gear pump has many advantages in application： small size,light weight,low noise, excellent self- absorption, good flow on the pulse and so on. However, because of the complex shape of tooth profile, the machining is more difficult. Base on the gear meshing principle, the equation of cycloidal gear tooth profile has been derived in the paper, and the approach of two type fillers is discussed. Using Visual Basic6.0 in Auto- CAD platform, the parameter drawing of the full gear tooth curve is achieved. It is of great significance for further analysis of the meshing character and the special mechanical properties of the gear pumps.
