you can achieve a decent efficiency of 70% or higher using a bronze wormwheel and 2-lead steel worm if they are turning ok, and should not backdrive either. |
A worm gear's efficiency is inversely proportional to its tendency to backdrive. A more efficient worm gear will more easily backdrive, and vice versa. Worm gears aren't really a magic solution to this problem, unfortunately.
