Re: Trouble: AndyMark Mecanum wheels

Are you suggesting hubs that are large that match the circumfrence of the twisted and bent carrier plates almost like reinforcing the wheel?

Re: Trouble: AndyMark Mecanum wheels

No, what he meant is that a single hub makes the wheel itself carry the torque between the two plates of the wheel. If each of the plates has a hub, then the torque is carried by the driveshaft, which is far stronger than the wheel for this type of loading. This should eliminate twisting damage, unless the shaft itself gets twisted.

Exclamation Re: Trouble: AndyMark Mecanum wheels

No I am suggesting just the hubs like Andy Mark supplies. I should mention we used 8 inch wheels which were the only ones available last year. No the hubs are not for use as side bolsters for strengthening but for alignment. Without the hub on one side you are relying the torque of the bolts to hold the wheels square and that when you assemble the rollers they will be equal length. What happens is as the wheels are used you get a racking motion as that non hub side floats back and forth (not supported by the shaft) and soon the nuts loosen and when you do a quick reversal of direction the inertia can twist the plates.
