The connections between the parts seems correct. The configuration you describe has a fixed ring gear. You applied a torque to the revolute joint between the planet gear and the carrier. How is that achieved in reality since the planet gear circles around the sun gear?  I can see either 1) applying a torque to the sun gear relative to ground and controlling rotation of the carrier axle relative to ground or 2) applying a torque to the carrier axle and controlling the rotation of the sun gear.

Under Analysis Settings, did you turn on Large Deflection?
