Differential Gear. Sweep on face of Cylinder

[mm391]

I have been using Creo Parametric and have found good tutorials online for the sweep function but all the tutorials place the gear teeth on the outside of the cylinder. I want to create differential gear with the teeth on the face of a cylinder, sweeping from the outside of the face to the inside. Can anyone help me and let me know this can be done or any tips to help me do this. (I am trying to model the largest of the gears on the attached photo)

Thanks

This is a hypoid helix gear and getting an accurate tooth will be virtually impossible in any CAD software. Best you can hope for is an approximation. I allow the gear software to figure this out and only create the blank in Creo. Depending on the gear software, you may be better off importing and exported model from the gear software if you need to show a visual representation.

you can download spiral bevel and straight bevel gear pairs from this site
Bevel Gears Spiral Bevel Gear Pinion Shafts Plastic Bevel Gear Injection Molded Bevel Gears
available in pro/e format. Using model player you can then see how to create such gears.
