Abstract
A rotary mechanical transmission, includes: a containment structure, a first rotary element, connected to a drive unit to define a mechanical power input unit and rotatable about an axis. The transmission also includes a fixed guide and a second rotary element, rotatable about said axis and defining a power output unit. A connecting element extends along the axis and couples to the first rotary element by a first threaded connection. The connecting element is also coupled with one of either the fixed guide and the second rotary element by a second threaded connection, and with the other of the fixed guide and the second rotary element by a linear guide parallel to the axis. The first threaded connection and second threaded connection have different pitches in such a way as to vary the angular speed between the connecting element and the first rotary element.
