Gear Profile Help Required

Hi All,

 

I was hoping that one of you would help me to tweak these two gear profiles to make them mesh as they should. I would like to keep the overall sizes as they are what I am after, but the meshing is not quite right and I am not sure the shape is correct. The overall size can change slightly, if need be, but not too much. 1 full turn of the spur gear will turn the ring 1/3 of a turn. If it would work better to have a 6 tooth spur gear and an 18 tooth ring, I am fine with that.

 

Currently it looks like this.

 

I started by working something out with Matthias Wandel's Gear Tool app, but that is just two parallel gears, that I thought would be a good starting point.

I have attached the SW2019 files via pack and go, so everything should be there.

 

Thanks in advance for sharing your engineering experience with me.

 

EDIT: I swapped the files. I just changed the start plane for the ring gear tooth and added a bit to the center.
