The present invention relates to an epicyclic speed reducer (), comprising a casing () comprising a first () and a second opening () arranged on opposite faces of said casing (). The casing () houses inside it: a first sun gear () fastened inside the casing () at said first opening (); a second sun gear () coaxial with the first sun gear () with the axis passing from the first opening () to the second opening (); a first planet gear () adapted to describe a circular orbit around the first sun gear (); a second planet gear () adapted to describe a circular orbit around the second sun gear (); a supporting element () interposed between the first () and second () sun gear and adapted to rotate around the axis, the supporting element () connected to the first () and second () planet gear in such a way as to allow a relative rotation of the supporting element () with respect to the first () and second () planet gear; a first belt () connected to the first planet gear () and to the first sun gear (); a second belt () connected to the second planet gear () and to the second sun gear (). Moreover the supporting element () is provided with a seat () coaxial with the axis and adapted to be fitted on one end () of a driving shaft such that when the seat is fitted on the driving shaft the supporting element () and the driving shaft are rigidly connected.
