I think this is at the root of my disagreement with your position on the basic operation of the torsen and any variant.
Do we agree that when the outputs are being driven equally (no differentiation) that a component of the input thrust vector places an axial load on the worm gears? I think yes.
This is where the friction comes into play. Under load, at the onset of differentiation, those gear teeth do rub relative to each other. They are not involutes. (edit: They do have that component in their shape but they are somewhere in between worm and spur in operating principle.)
It is that very same friction on which the torsen relies. The only time a torsen truly behaves like an open diff is when there is zero torque applied to the input.
Without any statement to consequence of continuous operation, do we agree on these points academically?
