摘　　要：为获取定轴多分支功率分汇流齿轮传动的真实均载情况,提出一种基于函数法的静力学均载特性分析方法,综合考虑系统构成功率流闭环的特点以及误差随机性的影响,系统地分析了两级定轴三分支(星型)齿轮传动的均载特性,并定量分析了其误差敏感性,最后通过与现有算例的对比分析,对上述方法的准确性进行了验证。研究结果表明:制造和安装误差随机性对系统载荷分配的影响不可忽略,尤以误差值随机性为甚;函数法计算均载系数时可有效避免截断误差,又因计入了误差随机性的影响,故更接近真实情况。In order to obtain the actual load sharing performance of fixed-axis multi-branch power-split gear transmission,a method based on function method for static load sharing characteristic analysis was proposed.Considering the power closed-loop and error randomness,the load sharing characteristics of two-stage fixed-axis three-branch(star)gear transmission were systematically analyzed,and its error sensitivity was quantitatively analyzed.Finally,the above method was verified to be correct compared with the existing examples.The results showed that the manufacturing and installation error randomness on the system load distribution cannot be ignored,especially the randomness of error values.Function method can effectively avoid truncation error when calculating the load sharing coefficient,which was closer to the actual situation when considering error randomness.
