skewed worm gear

[spears]

I am looking for reference information on skewed worm gears. All of the info I have found is related to a 90 degree angle between the non-intersecting shafts. I am looking at designing a worm and worm gear assembly where the shafts are skewed at 30 degrees.

Thanks

"Analytical Mechanics of Gears" by Earle Buckingham covers this.
