7 is suggested for practical considerations it is desirable to adopt an equal tangential load partition between the first bearing 155 and the second bearing 150 and between the third bearing 180 and the fourth bearing 190 that is u03c6 21 1 and u03c6 43 1 consequently the stiffness relationships at the first second third and the fourth bearing positions are determined as the locations for the first and second bearings and for the third and fourth bearings along the respective axis about which they rotate are then determined as turning to the fig8 a and 8b illustrate an exemplary planet carrier for obtaining the desired stiffness relationships the carrier structure includes a base hub 162 for supporting the drive planet gears 122 at equidistantly spaced housings and a upper plate 164 which in conjunction with the base hub 162 supports the idler planet gears 170 at equidistantly spaced and axially aligned reinforced housings the base hub includes a tapered portion 168 and a splined boss 169 the upper plate 164 is supported in the axial direction by a set of support posts 166 disposed between the upper plate 164 and the base hub 162 about the circumference of the base hub 162 those of ordinary skill in the art will recognize that are other carrier configurations that in conjunction with suitable supporting bearings will provide.
