Abstract:
A torque transfer device has plural planets arranged for planetary rotation about one or more sun gears and within one or more ring gears. Each planet includes at least one planetary gear set comprising plural planetary gears connected to rotate together, but having a different diameter to form a differential gear system. To improve load sharing, the plural planetary gears of each planetary gear set may have a different helical angle, the plural planetary gear sets being axially movable with respect to one another. Alternatively or in addition, the planetary gears may be made flexible with respect to radial forces.

Claim (Index 1):
A torque transfer device, comprising:\n plural planets arranged for planetary rotation about one or more sun gears and within one or more ring gears, the plural planets each including a respective first planetary gear set comprising plural planetary gears connected to rotate together and having different pitch diameters; a first output gear of the one or more sun gears or one or more ring gears being arranged to mesh with a respective planetary gear of each first planetary gear set; a first reference gear of the one or more sun gears or one or more ring gears being arranged to mesh with a respective planetary gear of each first planetary gear set; in which one or more of D or E or F or G, where\n D is the plural planets number at least 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 and one or more of the one or more sun gears and/or one or more of the one or more ring gears are formed of a first material with yield strength-to-stiffness ratio greater than 0.10; \n E is the plural planetary gears each have a number of teeth on each part of different pitch diameter and the number of teeth is the same on each planetary gear and on each part of different pitch diameter; \n F is the torque transfer device further comprises a respective first input gear of the one or more sun gears or one or more ring gears, the first input gear being arranged to mesh with a respective planetary gear of each first planetary gear set.the planetary gears are mounted on double bearings that are each adjustable by one or more shims to adjust pre-load of the bearings; and \n G is the planetary gears of each planetary gear set, the sun gear and the ring gear each have one or both of a conical taper and a profile shift.
