To create a spherical tool-path around a shaft I am currently using planes at 24 degree intervals around the part with a line on each plane at 1 degree increments, 1 shaft revolution = 15 degree roller-cam rev.
I would like to create the tool-path line by using law curves from which I can form a surface and use thicken to cut a roller cam path. Process images below.

Could you post your part model, not the while assembly, just the completed 'worm' gear part? Or at least a higher quality image of the Drawing which could be printed/plotted? And what is the diameter of the cam rollers?
Neither of the drawings indicate the actual diameter of the cam followers. I won't need the part as I think I have enough here to model what I'll need to duplicate what you're doing, but I still need to know the cam-follower specs.
Also, what version of NX are you running?
this is an nice example of solid sweep.
AFAIK there was something simmilar anounced for nx9, in nx10 beta I haven't found it.
Is there a roadmap when solid sweep will be introduced in nx?
Here is one method that I think will get what you are asking for. I didn't use law curves, but rather a combination of sketches and a swept feature. You can use the expression editor (or the "user expressions" section in the part navigator) to edit some basic input. The model updates reasonably well for small changes, larger changes will require some tweaking to the sketches and/or swept feature.
Attached file is NX 8.5 format.
