I need some live axil design tips!

a little advice to you, DONT USE LIVE AXLE DIRECTLY OFF BANE BOTS P80's the e rings inside the gearbox break all the time, then they have to be taken apart and fixed.

we typically use collars, but we taper the edge on a mill or with a grinder so that the edge of the collar does not rub against the bearing seal. key-stock or hex broached axles are necessary to drive the wheel. with live axles i also would recomed a larger diameter of axle, while 1/4 or 3/8 axle is fine for dead axle, 1/2 or 5/8 is better for live axle, good luck.

We direct drove 2 traction and 2 omni wheels off of P80s last year, but we had the shaft run through a bearing block first so the internal bearings of the gearbox wouldn't have as much load.

I know for a fact that each of the crab drive modules on our robot this year had a snap ring (about 1/2" diameter I think, but don't quote me) holding them to the shafts that essentially bore the weight of the entire robot, which i would think would fall around 25 lbs per snap ring or so when you consider that they don't bear the weight of the wheels themselves and then the battery is added. So if you are concerned about their durability when bearing force, I would think it shouldn't be a concern. The only times I know of this season when we broke or warped a snap ring was when we were taking them off or putting them back on. They were very reliable for our application, but I can't say much about their application in live axle design.
