作者谢雄伟（2019）在《面向装配的RV减速器计算机辅助公差分析及优化设计》一文中研究指出：RV减速器具有承载大、传动比大、回差小、体积小等突出优点,是工业机器人关节驱动装置的重要部件。RV减速器零件多,装配精度高,回差性能通常要求小于1’。实际加工的零件尺寸存在误差,装配后累积误差变大,装配成品率不高。国内RV减速器摆线轮和针轮之间的装配,大多采用修配的方式,严重影响生产效率。本文以RV-40E型减速器为对象,基于零件之间的装配约束关系,建立装配尺寸链。为了确保减速器具有良好的传动性能,参考摆线轮磨齿机偏心距系列设计短幅系数;为了补偿零件制造和安装误差,并具有一定的径向间隙,选用负等距加负移距的修形方式,运用MATLAB优化设计摆线轮修形量。分析影响减速器回差性能的主要设计参数,以零件加工成本为目标函数,许用回差(≤1’)和装配尺寸链为约束条件,在运用遗传算法初步设计摆线轮、针轮、曲柄轴等零件公差的基础上,基于3DCS三维公差分析软件,建立公差仿真模型,以偏心距、摆线轮和针齿之间的齿侧间隙评价RV减速器的装配性能,模拟实际生产装配,对公差仿真模型进行敏感性分析,同时进一步优化上述零件公差。最后将零件误差反映于减速器三维模型中,基于CATIA软件建立减速器虚拟样机,导入ADAMS中进行回差仿真分析,对零件公差优化效果进行验证,仿真结果表明:公差优化前的回差为0.002’～1.07’,公差优化后的回差为0.07’～0.85’,验证了优化设计零件公差的有效性。公差优化前,3.78%减速器的偏心距不符合设计要求,26.7%减速器的摆线轮和针齿齿侧间隙小于0.001mm或出现干涉。公差优化后,回差、偏心距均满足设计要求,摆线轮与针轮之间间隙大于等于0.001mm,装配成品率满足“6σ”准则,达到99.73%。减速器零件的加工成本仅增加6.08%,装配后每台减速器成本下降22.24%。敏感性分析结果表明:影响摆线轮装配性能最大因素是摆线轮修形误差和针齿半径误差,其次是摆线轮圆周累积误差和针齿孔圆周位置度,最后是摆线轮齿圈径向圆跳动和针齿分布中心圆半径误差;摆线轮修形误差、径向间隙、针齿半径偏差和针齿分布中心圆半径偏差需合理设计;主轴承和针轮之间的同轴度对偏心距、摆线轮与针齿之间的齿侧间隙均有一定程度的影响。本文所建立的基于3DCS的RV减速器三维公差分析模型,对RV减速器的国产化、提高实际生产装配成品率、降低减速器整机生产成本,具有理论指导意义和实际应用价值,为RV减速器零件公差的优化提供了一种方法。
