We're working on a similar design for sim motor/Jaguar/encoder control/Mecanum wheel. Here're some links that describe gear design that have been discussed in this thread:

Surface hardening and polishing of gear wear-in
Gear tooth strength
Worm gear "anti back-drive" or "self locking"

We looked at worm gear to allow getting the CIM motor 90 deg to wheel but are pursuing a 2-stage design with planetary on the wheel shaft and bevel for 90 deg transition:



Do you have advice on where to source gears? I've only found expensive sets for industrial fabrication and very cheap hobby gears.
