<p>The rotary motion of an input shaft is firstly altered into a controllable rotational oscillation of an intermediate member and subsequently, by means of an overrunning clutch mechanism, this oscillation is transformed into one way impulses towards output shafts which drive the loads. The connecting mechanism between the input shaft and the intermediate member controls, according to its condition, the amplitude of the angular oscillation of the intermediate member within a minimun/maximum, defining the transmission ratio. Inherent drawbacks like the strong impact loads are eliminated as long as the output shafts drive the loads through proper elastic connections while additional overrunning clutches, secured to the casing, prevent the reverse motion of the output shafts.</p> |
