Banebot 56mm gearbox - double D related

[dapub]

Is this a problem only with a 2 motor setup? Should we be concerned if we are just using one CIM per gearbox?

From the data we have to this point, it looks like it could be a problem over time for even the single motor CIM drives if driven hard back and forth for many cycles. I think it will take significant cycles to fail but based on the experience of Team 166, I think it will fail.

The good news is that when it fails it doesn't seem to take the rest of the gearbox down with it. It is not ideal but it is something.

Dr. Joe...

When we reported the gross failure of one of the drive systems, we failed to mention that we pulled the other three gearboxes off and observed the same damage, although to a lesser degree.

Ron Reich, a new ME mentor on the team, had done the research and determined that the 4140 prehardened steel would provide double the resistance to stress that the original carrier plates can withstand.

We will be having new plates made and as soon as we get them, we'll report back on how well that works.
