Determine the sign of torques for a planetary gear system
Determine the sign of torques for a planetary gear system
(OP)
I am trying to calculate the power distribution of a planetary gear system,specifically a wolfrom system. I have posted a complete description of my problem here. Any help will be appreciated.

Your schematic does not provide details such as the number of planet gears used or the positional constraints used for each member. So the load distribution between the (multiple?) planet gears cannot be determined.

It looks like users at Stackexchange have similar difficulty with understanding your schematic.

By "load distribution on the rings", I assume you mean the forces at the ring gear tooth contacts? These forces are applied by the planet gear teeth. The distribution of the planet gear tooth contacts around the circumference of the ring gear will depend on the mesh contact ratios, the number/spacing of planet gears, the profile/index accuracy of the gear teeth, and how the gear components are constrained. For example, a simple 3 planet epicyclic can have very good load sharing between the planets, but as the number of planets increase it gets more difficult to obtain even load sharing.
