Paul,

Knowing how thorough you are I would be surprised if you had not
considered the following:

The rollers in your proposed traction drive would have to have perfectlymatched OD's or
there will be different degrees of bearing side load and roller skidding(heating) at the contact
points. The effect of these differences are way beyond my analysis
capability but they should
be considered

Well first it been done more than once and second we are having them
precision ground to probably +/- .0001 That is one ten thousands of an
inch. The heat will happen no matter what. We are pumping the oil
through a cooler.

BTW you can buy precision rollers off the shelf. What you do is buy a 20 inch
diameter roller bearing and grind the outer race apart and remove the rollers.
You now have hardened, precision and polished rollers enough for three or
four traction drives.

Paul Lamar ...No rotor no motor.

Or you could grind them from whatever size stock to the size you want
on your lathe w/ a tool grind post then part them off in the thickness you need.
You'd end up w/ perfectly matched od's  Id's might be a bit tougher but could
be accomplished in the same manner..

Unless I'm missing something pretty significant....
