摘　　要：为达到纺织装备用行星减速器高传动效率和低噪音等要求,构建行星减速器三维数字化样机,并以此基础对该减速器第二级行星齿轮传动系统进行接触分析和齿面修形研究。以齿轮传动误差、啮合刚度、齿面法向力为评价指标对行星齿轮进行修形分析,通过改变不同修形参数分析其对修形指标参数的影响,最终确定行星齿轮传动系统的最佳修形方案。研究表明:行星齿轮传动系统的传动误差峰峰值由未修形时的0.68μm降为修形后的0.25μm,降低了约63%;齿面法向力和轮齿啮合刚度不同程度减小,改善了行星齿轮啮入、啮出冲击,有效提高了行星齿轮传动系统的传动效率,对行星齿轮传动系统的减振降噪提供了参考。In order to meet the requirements of high transmission efficiency and low noise of the planetary reducer for textile machineries,a three-dimensional digital prototype of the planetary reducer was constructed,and on this basis,the contact analysis and tooth surface modification research of the second-stage planetary gear transmission system of the reducer were carried out.The gear transmission error,meshing stiffness,and tooth surface normal force were used as evaluation indexes to study the modification of the planetary gear.By changing modification parameters to analyze its influence on the modification index parameters,the best modification plan of the planetary gear system was finalized.Studies show that the peak transmission error of the planetary gear transmission system is reduced from 0.68μm before modification to 0.25μm after modification,reducing by about 63%.The normal force of the tooth surface and the meshing rigidity of the gear teeth are reduced to varying degrees and improved.The impact of the planetary gear meshing in and out is effectively improved,and the transmission efficiency of the planetary gear transmission system is effectively improved,and it provides a reference for the vibration and noise reduction of the planetary gear transmission system.
