Re: Banebot Transmission Issues
 
Well this is a big, costly issue here. We are at the beginning of week 4 with a significant chance that drivetrains and manipulators will be failing cross the country. It is unfortunate that this problem has come around and who's fault it is, is truely unimportant.

What we need to do is solve the problem, thats what we are here for anyways. Its always been that way, and for the rest of your life in engineering always will be this way.

I thank Dr. Joe for his hard work to figure out the issue, and it is unfortunate that they switched from Paul's kit bot transmission but the switch was made so lets figure out something here.

I know the changes aren't "hard" but one of the issues I fear is the teams who are buying these gearboxes in the first place are not the most mechanically enabled. It is extremely likely that a majority of the teams who have purchased these, don't have the resources nor the required experience to change them.

Without any testing equipment of my own to verify the quality, I'm pretty much in prayer these transmissions don't fail on our manipulator. I won't even find this out until the early weekend. By then, we could be in significant trouble, but I'm still working towards a solution, and in the process would like to help figure out an easy way for teams to remedy the situation.

For example petitioning FIRST to bend the rules and allow FRC 2006 transmissions that Paul designed. Or perhaps come up with a unified design modifying the exsisting gearboxes such that failure will not occur.

I offer my help to work towards a solution, we all realise there is a potential problem, so lets all work towards the solution. The complaining should be avoided, and I appreciate those who are already working hard.

Joe,

I am not a mechanical engineer, but I am the only engineering support my team has.

Our team has a 4 wheel drive skid steer (tank steering) system with 1 cim and 1 56mm transmission with the 16:1 change kit on each wheel. We are chaining the front and rear wheels together to avoid loss of power should a wheel be lifted off the floor.

Considering this is our drive train and the that we will be playing a good bit of defense (shock through the system), How concerned should I be with these transmissions and what can I do to correct the issue.

If we were to fabricate a new carrier, what sort of material would be sufficient? and can drawings be made available?

I am closing this and several other threads. Please continue the discussion on the following thread:
