The device comprises two speed reduction gears with coaxial shafts and a fixed support interposed between the reduction gears and housing a first hollow shaft coaxial to the shafts of the gears and in which there is rotatably housed a second independent shaft coaxial to the shafts of the gears. Two pulleys are rotatably mounted on the first hollow shaft and are rigid with toothed flanges which engage frontally in internally splined tubular elements within which sleeves are slidable coaxially but externally to the two shafts. The sleeves are engageable with the shafts and with the tubular elements.
