1. A planetary mechanism comprising:
a stationary frame,
a first gear connected to the frame, the first gear having a central axis of rotation and having a teeth number Z1,
a second gear supported on the frame coaxially with the central axis of rotation and being configured to rotate freely and endlessly about the central axis of rotation, the second gear having a teeth number Z4,
a carrier supported on the frame coaxially with the central axis of rotation and being configured to rotate freely and endlessly about the central axis of rotation, the carrier having a plurality of planetic axes disposed parallel to and at a distance from the central axis of rotation, the plurality of planetic axes being equally angularly distributed around the central axis of rotation,
a plurality of shafts, each corresponding to a respective one of the plurality of planetic axes, each shaft being supported on the carrier coaxially with its corresponding planetic axis, and each shaft being configured to rotate freely and endlessly about the corresponding planetic axis,
a plurality of third gears, each being rigidly connected to a first end of a respective one of the plurality of shafts coaxially with the corresponding planetic axis, each third gear cooperating with the first gear and having a teeth number Z2, and
a plurality of fourth gears, each being rigidly connected to a second end of a respective one of the plurality of shafts coaxially with the corresponding planetic axis, each fourth gear cooperating with the second gear and having a teeth number Z3,
wherein the teeth number of the first gear, the second gear, each of the third gears, and each of the fourth gears satisfies the relation:
(Z1−Z2)*(Z4−Z3)>0, and
wherein the teeth number of the first gear, the second gear, each of the third gears, and each of the fourth gears further satisfies the relation:
(Z1+Z2)*moduleR=(Z4+Z3)*moduleA,
where
moduleR is the module of the gears pair: the first gear and the plurality of third gears, and
moduleA is the module of the gears pair: the second gear and the plurality of fourth gears.
