谐波齿轮传动工作时,啮合区内柔轮齿和刚轮齿发生周向变形,如果它们不变形就会重迭(即干涉)。假设备柔轮齿上的啮合力正比于该柔轮齿和刚轮齿的重迭量,用边界元素法计算柔轮变形,再用变形后柔轮齿和刚轮齿的重迭量去修正啮合力分布规律。如此反复计算,最后使啮合区内各齿对间的重迭量趋近于零。此时的啮合力分布规律即为准确的齿间啮合力分布规律,并以此啮合力分布规律计算出柔轮齿的齿根应力,解决了谐波传动计算中这一难题。
When the harmonic gear drive is in operation, the flexion teeth and the just gear teeth in the meshing zone undergo a circumferential deformation, which will overlap (ie interfere) if they do not deform. Assuming that the engagement force on the flexible gear teeth is proportional to the amount of overlap of the flexible gear teeth and the gear teeth, the boundary element method is used to calculate the deformation of the flexible wheel, and then the amount of overlap of the flexible gear teeth and the rigid gear teeth is modified The distribution of meshing force. So repeated calculations, and finally the amount of overlap between the teeth in the meshing area close to zero. The law of the distribution of the meshing force at this time is the accurate distribution law of intermeshing force, and the tooth root stress of the flexible gear teeth is calculated by the distribution of the meshing force, which solves this problem in harmonic drive calculation.
