Model for worm wheels and worm gears

Hi All ,

Does anyone have models for worm wheels and worm gears,which is scalable?

I have checked the ptc part community and 3D model-space as well,but they don't give me options to change the profile on the basis of the following:

Pressure Angle

Module

PCD

No of starts

These are critical parameters for me in order to change the profile as per my requirement.

Thanks,

MA
