摘要

双圆弧齿廓谐波传动对装置传动性能具有显著影响,基于改进运动学谐波啮合理论,利用MATLAB设计了适用于谐波传动的公切线双圆弧齿廓,并对其干涉、侧隙、变形、轨迹等进行啮合仿真分析。研究结果表明,所设计双圆弧齿廓谐波传动在波发生器转角大于62°时脱离啮合,啮合齿数多;在柔轮轮廓未脱离啮合前,轮齿无干涉、始终保持连续接触、啮合点不断改变、啮合状态良好,有利于提高谐波传动的承载能力、传动精度、扭转刚度等性能。

Abstract

The double circular arc tooth profile of harmonic drive has a significant impact on the performance of gear transmission,based on the kinematics of harmonic gearing theory,the common tangent double circular arc tooth profile that suitable for harmonic drive is designed by using the MATLAB,the meshing simulation analysis of the interference,lateral clearance,deformation,trajectory is carried out. The results show that the design of double circular arc tooth profile harmonic drive is out of meshing when the turn angle of wave generator is greater than 62°,and the number of teeth in meshing is more; before the flexible gear contour out of meshing,the gear tooth without interference,always maintain continuous contact,the mesh point changing,and meshing in good condition,it is help to improving the bearing capacity of the harmonic drive,transmission precision,torsional stiffness and other performance.
