I was wondering if one of you understands worm gears and could help me figure out the gear ratio for the two illustrated gears. I am thinking about a new tutorial and it requires a worm gear and I just can't grasp this.
Ideally I want a worm gear where if I turn the worm 1 full turn it moves the round gear 10 degrees out of 360. Or I just want something that will mesh as one would expect. I am trying to utilize a worm gear that can be found on McMaster-Carr for ease and below is what I have worked out so far but only as to being able to mesh, which I see says, For gears and worms to mesh correctly, they must have the same pressure angle and pitch.
I am just doing some initial setup using SolidWorks as this has mates to allow me to see this functioning and thus letting me know I have it as required. Then I will repeat in TurboCAD having figured out the position and having something intelligent to say during the tutorial.
If you can help please use non-engineering speak to explain. :-)
