Point me to a place to learn about worm drive design?

  1. Aug 10, 2014 #1
    Hey guys!
    I am currently creating some automated snips for trimming plants.
    I am using auto desk inventor to design it all.
    The design and concept is solid and modelled/animated to show proof of operation.
    However now i want to try prototype - i can sort out everything aside from the gear.
    I know my gear ratio, the diameter of both gears and the teeth number (so modulus).
    Now i need to try see if i can actually accurately model the gear in inventor (currently just used a 1:40 worm gear that i fiddled to my required dimensions). However the issue is that i have no idea where to start learning!
    Google hasn't been overly helpful in this scenario (or i just missed something good).

    Any help or advice is greatly appreciated!

    thanks alot for taking time to read!
