Connecting Wheels to Motors

Let's Make Robots Project Ideas
1

Hi All

I’m new to this so please be gentle.

I have 2 motors (see attachment) which have a 11mm shaft and a 4mm keyway. I would like to connect the motors to the wheels I have purchased (see other attachment).

The wheels have the following specification:

Wheel size :- 2.5J x 8"

Wheel manufacture :-Mefro
Wheel colour :-white
No. of studs :-4
PCD :-4"
Center hole dia :-66mm
Stud holes Dia :-11mm
Offset :-0mm

Sorry, if I havent given enough information but I’m not too sure what else you may need.

Can anyone please advise on what would be the most effective and cheapest solution,

Thank you!!

Hi nickbungus

Welcome to the RobotShop Forum. Unfortunately we currently don’t have a hub that would fit either the motor or the wheel you specified, and it is doubtful that one exists on the market. You would therefore need to make a custom hub either in one part or two. If you make it in two parts, you may be able to use a standard 11mm hub (which you might find online) and a custom (flat) peice with the right hole pattern for both the wheel and the hub. You may also want to consider offsetting the shaft and using sprocket/chain.

Hope this gives you some ideas,
