Abstract
The invention relates to helical gearing having a spindle and a counterpart, which engages on a thread of the spindle. The counterpart is, for example, tube-shaped, encloses the spindle concentrically, and has rollers on the inside of the counterpart which roll on thread flanks of the thread. By rotation of the spindle, the counterpart is driven like the nut of a spindle drive. The thread of the helical gearing according to the invention is provided with a changing pitch and thus a changing gear ratio.

1-12. (canceled)
A helical gearing, having a thread and having a counterpart component that engages the thread, in which helical gearing the thread is able to rotate relative to the counterpart component so that a rotary motion of the thread relative to the counterpart component causes a sliding motion of the counterpart component relative to the thread, wherein the thread has a changing pitch.
