摘要:

提出一种基于柔轮弹性变形的包络精确算法,精确计算切向位移引起的转角和齿廓对称线相对于径矢的转角。利用迭代法计算变形后啮合端齿廓共轭位置;根据柔轮中性层曲线不伸长条件确定输出端转角。通过算例对常见的五种波发生器作用下的轮齿的共轭区间和共轭齿廓进行比较计算,验证了算法的有效性和正确性,并给出了近似算法引起的偏差。总体来看,近似算法对共轭区间影响较大,对形成的共轭齿廓影响较小。

Abstract:

An exacted conjugate algorithm based on elastic deformation of flexspline was presented herein with exact calculations of the rotation angles. In meshing part, the actual conjugate location of tooth shape in deflected form was calculated by iterative method. The corresponding rotation angle on undeformed output end was determined according to the equal length on neutral line as that prior to bending. The correctness and effectiveness of proposed algorithm were demonstrated by examples in which the conjugate domains and conjugate tooth profiles were calculated in harmonic drivers driven by 5 commonly used wave generations, and the differences of the approximation were given. As a whole, the approximation causes significant influence for conjugated domain, but little difference for conjugate tooth profile.
