Abstract:
A work vehicle reduction drive assembly includes a drive having a drive shaft mechanically linked to a movable work component through a planetary gear train is. The planetary gear train includes a ring gear having a tooth count of Tring, a sun gear having a tooth count of Tsun, and a planet-carrier assembly including a plurality of planet gears each having a tooth count of Tplanet. Tring, Tsun, and Tplanet are selected such that each planet gear in the plurality of planet gears contacts at least two teeth of the sun gear and at least two teeth of the ring gear in all rotational positions of the planetary gear train. The sum of Tring and Tsun yields a positive integer when divided by a first number from a set {3, 4, 5} and when divided by a second number from the set {3, 4, 5}.
