Abstract Planetary gear sets combine the characteristics of high-power density and compact design which are beneficial for a wide range high-performance applications. Embedded in efforts resource efficiency cost reduction, new challenges arise regarding lightweight design. An accurate prediction load sharing on individual planetary gears especially distribution meshing is major importance. A uniform enables tooth meshes without increases oversizing. However, varying has been observed gearboxes with respect to rotation carrier caused by misaligned central shafts gearbox. This behavior influenced several factors, such as manufacturing assembly deviations, rigidity shafts, housing bearings, number planets, quality wheels operating conditions. To determine exact distribution, detailed simulations or extensive experimental prototype tests required. In an early phase, these boundary conditions not yet defined their effect moving contact pattern therefore cannot be reliably considered. Thus, this paper investigation influencing factors regard presented. Based data recommendations derived.
