Planetary Herringbone Wave Gear

**update**
These will not work.... despite a good theory my software Solidworks 2013 is not calculating helix angles correctly.... i have confirmed this with 2018 but dont have regular access to 2018 so when i do i will try to fix these files. presently the ring gear helix is producing a shallow angle and is intersecting the other gears.

I will have to manually tweak the helix angle to make one that functions

This is a concept of a rounded tooth gear in a helical planetary arrangement.

I couldnt find what these sort of gears were called so i made up a name for them, hence the "Wave Gear" since the tooth form is very much like a sine wave. Thought it is not symmetrical top to bottom of tooth.

This should be able to be printed in one shot fully assembled with enough clearance for the gears to move.

I look forward to trying this one out.

the first file is sun=20 planet=20 ring=60
the second file is sun=12 planet=12 ring=36

** UPDATE**
So far i ha
