  • Backlash correction system for compound planetary gear train
    Patent number: 10036450
    Abstract: A compound planetary gear train includes a sun gear, a stationary annulus gear, a first set of planet gears meshing with the stationary annulus gear, a moving annulus gear and a second set of planet gears meshing with the sun gear and the moving annulus gear. The planet gears are biased into contact with the annulus gears.

  • Gearbox with reduced backlash
    Patent number: 9631702
    Abstract: A gearbox includes two axially spaced epicyclic gear trains, each having a sun gear, axially spaced planet gears carried by a planet carrier, and a ring gear fixed to the gear box. One of the planet gears engages with the fixed ring gear, and another of the planet gears engages with an output ring gear. The sun gears of the two gear trains are mounted on a single shaft. The planet carriers of the two gear trains are mounted on a shaft so that they can freely rotate but have limited axial motion along the shaft. The two output ring gears are helical gears of opposite handedness.
