RE: how to calculate the spiral shaft

Imagine a piece of paper in the shape of a right triangle.

Imagine that it's special paper, of zero thickness.

If you hold one square edge parallel to the axis of a cylinder, and wrap the other square edge around the cylinder, the hypotenuse will form a helix.

Assume the cylinder is of the pitch diameter of the spiral shaft.  

Now, the problem has been unwrapped into a wedge; you can probably figure the kinematics from there.

www.roton.com is the website of a manufacturer of motion screws, and the site has a lot of handy and pertinent formulae for these calculations, as well as a beta version of a calculator program and a glossary of terms.
