Re: How much torque can the Dewalt Trannies take?

A quick note on the Robonaut V6. We did put six motors through a dewalt in '07 and I was completely shocked that it handled the torque. It's important to mention that we did see a couple sun gear failures that year that seemed to be caused by hard impacts (sudden stopping of drive). We made the design easily replaceable since we knew we were pushing the limits of the gear box. Overall I think it was as reliable as most (but not all) drivetrains that year.

Another important point... we were only running the drive in one direction. If the gearbox had to withstand the back and forth seen with tank steer I have little doubt it would have failed.
