在本文中，一个国家的最先进的接触力学模型的行星齿轮组研究的影响，一些制造和装配相关的载体和齿轮误差的行星之间的负载分配。考虑了三组不同的误差：（i）时不变的、与装配无关的误差，例如行星架针孔位置误差;（ii）时不变的、与装配相关的误差，例如行星轮齿厚度误差;以及（iii）时变的、与装配相关的误差，例如齿轮跳动误差。在此误差条件下，研究了n行星系统（n = 3 ~ 6）在准静态条件下不同驾驶位形下的行星均载特性。负载分配行为作为关键制造误差的函数被量化，并提出了更好的行星负载分配行为的设计准则。
In this paper, a state-of-the-art contact mechanics model of a planetary gear set is employed to study the effect of a number of manufacturing and assembly related carrier and gear errors on the load sharing amongst the planets. Three different groups of errors are considered: (i) time-invariant, assembly-independent errors such as carrier planet pinhole position errors, (ii) time-invariant, assembly-dependent errors such as planet tooth thickness errors, and (iii) time-varying, assembly-dependent errors such as gear run-out errors. With such errors present, planet load sharing characteristics of an n-planet system (n = 3 to 6) is investigated for different piloting configurations under quasi-static conditions. Load sharing behavior as a function of key manufacturing errors is quantified and design guidelines are proposed for better planet load sharing behavior.
