为解决传统齿轮副存在的回差问题，对设计、制造和安装过程中存在的误差影响因素进行了定量计算．通过考虑齿厚偏差、轴承径向跳动、中心距偏差和温度对齿轮变形的影响，提出了可自动变形补偿的金属橡胶复合齿轮副设计方法; 基于ABAQUS 有限元分析计算了高、低温对复合齿轮副变形的影响，得出了复合齿轮副在高、低温环境下的变形量和理论中心距预紧量; 实验考察在不同预紧量下金属齿轮副和复合齿轮副的振动响应情况．结果表明: 随着预紧量的增加，振动加速度先减小后增加; 预紧量的改变对金属齿轮副的影响较大，对复合齿轮副的影响较小，复合齿轮副相对金属齿轮副的改善效果随着预紧量的增加而愈加明显; 实验得到的最佳预紧量和仿真计算值基本吻合，从而验证了仿真分析的正确性．

In order to solve the return difference problem of traditional gear pairs,the factors influencing the errors in the processes of design,manufacture and installation are quantitatively calculated.Then,by taking into account the influences of tooth thickness deviation,radial pulsation,center distance deviation and temperature on gear deformation,a design method of the metal rubber compound gear pair with automatic deformation compensation is proposed.Moreover,on the basis of ABAQUS finite element analysis,the influences of high and low temperatures on the gear deformation are calculated,and the gear deformations at the high and low temperatures as well as the preloading of theoretical center distance are obtained.Finally,the vibration responses of the metal and compound gear pairs under different preloading are tested.The results show that ( 1) with the increase of the preloading,the vibration acceleration decreases first and then increases; ( 2) the preloading has a great influence on the metal gear pair but a little influence on the compound gear pair,and with the increase of the preloading,the improvement effect of the compound gear pair tends to become more obvious than that of the metal gear pair; and ( 3) the optimal preloading obtained by tests accords well with the calculated result,which verifies the correctness of simulation analysis.
