wheel drive

[Paul Copioli]

Here are a couple of suggestions:

(1) Use a trantorque. They are in small parts, but are considered a fastener and can be bought anywhere. Fenner drives have trantorques of all sizes.

(2) Have a keyway cut into your shaft. Keystock is sold in many sizes and will fit into the keyway you have cut into the shaft.

Depending on the size of your hole in the wheel, I suggest the trantorque. I would suggest a shaft no smaller than 3/8", so the trantorque outside diameter is 3/4" (that is the size the hole in your wheel has to be). Trantorques can be used right over keyways.
