Drive train problems at Peachtree

[ttldomination]

To provide slightly larger picture:

We used the VEX high traction wheels (6") with the versahub setup (as recommended on the versahub product page). The product in the image is indeed a versahub (1/2" bearing pilot).

Our DT is geared for about 9 FPS (slightly slower than the KOP) using 6" wheels. We generally get into quite a few pushing matches, but it's all within the expected scope of FRC gameplay.

Before one of our matches, we noticed a couple of the screws on the wheel assemblies (sprocket + versahub + wheel) were loose. Due to time constraints, we played one match and then proceeded to perform a full service on the DT (checking all wheels, tightening all chains, and adding loctite to all bolts on the wheel assemblies).

Upon on removing this particular assembly from the shaft, the entire assembly fell apart (literally) to reveal sheared screws and the versahub as you see above.

We're just happy we caught this before elimination rounds, where there's no telling how long this would've taken to become disastrous.
