BaneBots Tranny

[CidTeach]

Hello all,

I would like to share some concerns and experiences with this years BaneBots transmissions. We, like all, skurried to order a few p60's for manipulator and other uses. Once finally received, we cleaned them out, packed them full of quality grease, and bench tested them, as well as broke them in for ~1hr. Then we opened them back up, inspected, cleaned and repacked em. tested and installed them. This is a typical part of our build season, done with everything including AM tough boxes, our super duper super shifters etc.
When our drive team was practicing, light duty stuff, open field no competition, we noticed that the end plate had a tendency to shift slightly and then noticed phantom problems with our autonomous trials. The telescopic arm would not extend at the same rate all the time, at times jammed itself etc. We assumed it was friction and lubed it up and kept practicing. At both of our regionals this year we've had to replace the trannies due to binding - so bad we could not even extend our arm, either manually or tethered. Meanwhile the arm was designed and tested repeatedly, to retract slowly under its own weight ( it was powered up and down obviously).
We noticed the 4 machine screws provided did not reach the base mounting plate, only catching 2 threads - we upgraded to longer, stronger machine screws which slightly helped, but twisting still occurred.
Then the fatal flaw - the tiny roll pins intended to keep the ring gear stationary, failed/fell out etc, which rendered it useless.
We then spot welded, replaced roll pins, replaced screws, added stiffening plated etc, but the tranny kept binding and creating phantom problems during our matches. Replace and pray became our motto.

The p60's in question were 64:1 with rs775, only for speed reduction and redundancy. An older 16:1 p60 with rs540 used for prototyping worked just fine, but was way to fast.


I would like this thread to serve as a conversational piece for teams who had this problem, or similar. I would also appreciate this not become a ranting thread. Direct experiences please.
We are greatly disappointed with the quality of the newly designed p60's, BaneBots promises and the disservice they provided while being the sole vender of major importance in First this year.
