Does the other end of the axle protrude through the rear of the motor casing, could you add a second motor in tandem to the first by driving the other end of the axle.
I have got it,
the plate behind the hub on your photo, mount a drop plate or side plate,whatever works whether high low back front etc , to that original plate, then weld a trailer hub, stub axle,to the new plate just far enough away to clear the teeth of the sprockets, fix on the original hub put a small sprocket, mount a large sprocket on the rear of the trailer hub using the wheel studs of the trailer hub, piece of chain from one to the other, you have hub reduction.
ahemmm post 19only chain drive, not the method this way would be simple
not with my method you go straight from the original to the new hub with chain two total separate hubs you can pick up weld on stub axles for trailers and trailer hubs cheap just redrill to suite your wheelsWell I thought a lay shaft parallel to the output shaft, a sprocket on the output shaft via chain to sprocket on the layshaft, at a 1:1 ratio, then other end of layshaft sprocket via chain at 1:2 to wheel, that's a simple gearbox, but then I need bearings at either end of the layshaft
Sometimes you just gotta accept there is no really simple fixHmmm yes that would work quite easily but I don't want anymore weight, and like all A-Team style I like a challenge
F cough(nice to see your computer savvy and used a computer program or APP as they call them for your drawing lol paper and pencils are so yesterday lol)
