ABSTRACT:
An apparatus for producing predetermined torsional vibrations in a mechanical transmission is disclosed. The apparatus includes a summing gear arrangement including a non-revolving gear member such as of a planetary or differential gear assembly. The summing gear arrangement includes at least three shafts or three gears wherein the non-revolving gear member is rotatably mounted and is connected to a control capable of transmitting impulses corresponding to the torsional vibrations. The summing gear arrangement combines the torsional vibrations with a mechanical input thereto to produce an altered output.
