FACE-GEAR TRANSMISSION ASSEMBLY WITH FLOATING BALANCE PINIONS

摘要

A gear transmission assembly for transferring a drive torque from at least one power input to a primary user has at least one drive pinion carried by a respective power input shaft and meshing with a pair of facing coaxial counter-rotating ring gears having an axis perpendicular to the axis of the drive pinion and engaging between facing face teeth at least one transmission pinion having an axis perpendicular to the axis of the ring gears. The at least one drive pinion floats in the direction of the axis of the ring gears, while the at least one transmission pinion is supported by elements flexible in a circumferential direction with respect to the ring gears.
