Threaded Rod Worm Gear / Pinion
Description
This Fusion 360 file will parametrically create gears that can work with threaded rods or bolts either as a worm gear or as a pinion (using the threaded rod as a rack). The thread is defined by its dimensions as parameters and a diagram is included to explain what those are. You can either look the values up for a particular thread, or create a thread and measure it in Fusion 360. Clearance parameters are also included for fine tuning the fit. This is marked as a work in progress for two reasons: 1) I couldn't get the final Join operation to work parametrically (would break if I changed the number of gear teeth) so you'll have to perform that operation manually. If anyone knows how to do a "select all" for bodies or some other workaround, LMK! 2) I haven't tested it yet. I made one via a much worse (non-parametric) technique in the past that worked, so I'm pretty confident, but it still remains to be tried out.
