I'm assuming this means that you mount the spinning outer shell of the robot directly on to the output shaft of the gearbox? (A photo or CAD image would be helpful) If so, I can see why the gearbox would be prone to failure.

Might I suggest building a custom shaft to support the spinning part of the robot ( you could make it out of 1" diameter solid titanium if you wanted) and weld that in to your frame, then use a pulley from the gearbox output shaft to spin the outer shell? That way (espeically if you build a bit of slip at high impact in to the belt) your gearbox output shaft will not be supporting the load... or impact... faced by the spinning outer shell.
