The unique nature by which power is shared via multiple planets, makes epicyclic gearboxes an attractive solution for high power density, lightweight applications, such as aerospace transmissions. However, their complexity, including multiple load paths, unequal load sharing and phases of meshing, are such that the transmission error optimisation is substantially more complex than standard single stage parallel axis gearboxes. Here, an existing epicyclic gearbox was re-designed using the theory of phasing to minimise the magnitude of transmission error. Two considerably different epicyclic gearboxes were investigated: 1) A high contact ratio spur with out-of-phase planets, and 2) an integer overlap ratio helical with out-of-phase planets.
