From a mechanical engineering standpoint it is a bad idea. Modern chainsaws are direct drive and have 7 or 8 'teeth' on their directly mounted to crankshaft drive sprockets.

Worm drive is a technique used when large gearing reduction is needed and would result in extremely slow chain speed on a chain saw. Works well for a used car jack though.
