摘要

提出了一种保啮合性能的齿廓参数设计方法,建立了齿顶干涉判式,确定了干涉区域,基于共轭点和干涉区域齿顶点生成样本点,引导齿廓参数设计。该方法在已知一个齿廓设计另一个齿廓参数的过程中,既能避免齿顶干涉又保证共轭区间的啮合性能,省略了反复仿真分析、检验及修正过程。以一种谐波传动的齿廓设计为例,给定柔轮齿廓参数设计出刚轮齿廓参数;误差与侧隙分析表明,所设计的齿廓参数与共轭齿廓接近度好、侧隙分布理想,重合度及最大啮合深度得到保证;说明了该齿形参数设计方法是有效且能保证啮合性能的方法。

Abstract

A tooth profile design approach for harmonic drive（ HD） with nice meshing qualities is proposed. The criteria for tip interference judge,interference zone determination and sample points generation,which will achieve the tooth profile design well are proposed in this method. When one HD tooth profile is given,tooth profile parameters of the other conjugate tooth are sufficiently determined by this method,which can remove tip interference but guarantee the meshing performance on the conjugate zone without repeated simulation,interference check and revise. Taking the design of a pair of tooth profiles of HD as example,the tooth profile parameter of rigid spline is designed under the given tooth profile of flexspline. Analysis of fitting error and backlash demonstrates that the designed tooth profile of the rigid spline is very close to the theoretical conjugate curve,the backlash distribution is ideal,the contact ratio and maximum engaging depth are guaranteed,which proves that the tooth profile parameter design method is effective and can guarantee the meshing performance.
