Patent ID: 8747277

Claim:
A method for selectively positioning a support bearing about a shaft of a stepped gear assembly in a transmission system having more than one torque pathway between an input and an output to achieve an optimized load distribution among a set of drive planet pinions and idler planet pinions in the transmission system, comprising: selecting a pivoting position (L 1 ) of the support bearing along a stepped gear assembly shaft according to: L 1 L - L 1 = ( 1 - LR T 1 + LR T ) ⁢ D 0 D 1 where L represents a spacing between a large planet gear and the drive planet pinions of the stepped gear assembly; LR T represents a desired load distribution ratio at the meshes between the drive planet pinion and an idler sun gear and between the drive planet pinion and a ring gear of said stepped gear assembly; D 0 is a pitch diameter of the large planet gear in the stepped gear assembly; and D 1 is a pitch diameter of the drive planet pinions in the stepped gear assembly.
