Re: pic: Stripped VexPro gear
We had the same thing happen to us on our scaling mechanism. I believe we were using the 60 tooth 1/2 hex bore gear from VexPro. We have a CIM Motor that has 3 stages of AndyMark GEM Planetaries on it, along with a 1:3 gear ratio coming out of it.. totaling up to around 900 ft/lbs of torque. At Bayou, we went out in the quarter finals because we had 4 teeth shear on that gear. We couldn't scale because the robot sagged and got caught in that section of the gear that had stripped.

We ordered a steel gear from McMasterCarr and welded in a 1/2 inch socket. It worked throughout Rocket City flawlessly.
