Ran into a problem with the Banebot wheel/hubs on the jaycar motors. No matter what I tried the hubs would eventually slip on the drive shaft. The drive shafts of the jaycars are keyed, but the banebot hubs are not and require a set screw. I tried dimpling the set screw, using loc-tite, etc with no success. Eventually the hub would come loose and slip.
I decided to go with DFRobot wheels (KIT0044) which came with a keyed hub, so I ordered 4 thinking I’d use 2 wheels and have 2 spares. Turns out I ordered 4 sets of 2 wheels. Cost for two wheels and hubs was $39 with shipping.
Got the wheels and used some of the free time over the holidays to install them. Since these wheels are slightly larger than the banebots, I had to remove about 1/8″ on either side for clearance, but since its styrene it didn’t take too long. Here are pictures of the before/after:
The worse part of the hub slipping was the hub would then get stuck on the shaft. I would remove the set screw and still could not get the hub off the drive shaft. Which in turn meant I could not remove the motor from the mount plate. Thankfully my friend Greg cut me two more sets of mount plates and I purchased two new jaycar motors. Now I have spares! Here is the destructive testing I did to remove one of the hubs, still have one more to go.
