Abstract
A rotary mechanical transmission includes a containment structure, a first rotary element, connected or connectable to a drive unit to define a mechanical power input unit and rotatable about an axis of rotation, a fixed guide, a second rotary element rotatable about the axis of rotation and defining a power output unit and an intermediate roto-translational element, extending along the axis of rotation and including a first threaded portion, coupled to the first rotary element, and a second threaded portion, coupled to the fixed guide. The intermediate element is also coupled with the second rotary element by a linear guide parallel to the axis of rotation. The first threaded portion and the second threaded portion have different pitches and are at least partly separated along the axis of rotation. The intermediate element is defined by a hollow body and the second rotary element is inserted inside the intermediate element.
