摘要

为提高谐波传动的啮合性能,以100型单级谐波传动为例,基于柔轮弹性变形运动及改进运动学谐波啮合理论,求解渐开线轮齿共轭齿廓,并建立优化设计模型,采用MATLAB编程迭代方法对轮齿齿廓进行优化设计,为验证模型合理性,对优化后齿廓啮合状态进行仿真分析。研究结果表明,渐开线谐波传动存在有效共轭区间及有效共轭齿廓;为避免齿廓啮合干涉,共轭齿廓需采取三维空间齿廓;优化设计齿廓具有无装配干涉、无相对运动干涉、啮合齿数多及传动比大等优点,验证了上述模型的合理性。

Abstract

For the purpose of improving the engagement qualities of harmonic drive（ HD）,taking the HD with the drive ratio 100 as example,the basic conjugated tooth profile for involute tooth profile is calculated based on the modified kinematics method of HD and the elastic deformation of flexspline,the tooth profile optimization design model is established and calculated by using the iteration method of MATLAB,in order to verify the correctness of the aforementioned model,the engagement state of the tooth profile after optimized is studied.The results show that effective conjugate exist domain and effective conjugate tooth profile are found,in order to avoid the interference during the engagement process,the three-dimensional tooth profile must be applied as the conjugate tooth profile.Finally,the correctness of all of the aforementioned model are verified by the characteristics,such as non-interference during the assembly and movement process,more number of teeth participated in engagement and large transmission ratio.
