【摘要】：谐波传动轮齿齿廓对装置传动性能具有显著影响。为提高谐波传动装置性能,采用公切线式双圆弧齿廓作为柔轮齿廓,并建立以弧长为参数的双圆弧齿廓函数。基于改进运动学谐波啮合理论研究双圆弧齿廓谐波传动的共轭区域、共轭齿廓,并分析齿廓齿形参数和齿廓位置参数对共轭区域及共轭齿廓的影响规律。研究结果表明:双圆弧齿廓谐波传动在啮合过程中有2个共轭区域,且存在两次啮合及两点啮合现象;柔轮凸齿廓与凹齿廓圆弧半径、公切线倾角与长度、径向变形量系数、壁厚等对谐波传动的共轭角度与区间、共轭齿廓弧长、共轭齿廓半径与位置等影响显著,且研究实例中适当减小上述啮合参数或结构参数有利于提高谐波传动性能。
[Abstract]:The tooth profile of the harmonic drive gear has a significant effect on the transmission performance of the device.In order to improve the performance of harmonic transmission device, the common tangent double circular arc tooth profile is used as the tooth profile of the flexible wheel, and the double circular arc tooth profile function with arc length as the parameter is established.Based on the improved kinematic harmonic meshing theory, the conjugate region and conjugate tooth profile of double circular arc tooth profile harmonic drive are studied, and the influence of tooth profile parameters and tooth profile position parameters on conjugate region and conjugate tooth profile are analyzed.The results show that there are two conjugate regions in the double circular arc tooth profile harmonic transmission, and there are two meshing and two point meshing phenomena, the arc radius of the convex and concave tooth profile, the inclination angle and length of the common tangent line, the coefficient of radial deformation,The influence of wall thickness on the conjugate angle and interval of harmonic transmission, the arc length of conjugate tooth profile, the radius and position of conjugate tooth profile, etc.
