Document Type and Number:
Japanese Patent JP6533277
Kind Code:
B2
Abstract:
The present invention provides drive systems for rotating one or more wheels (16) of an aircraft landing gear (10) for the purposes of ground taxiing and/or spin-up prior to landing. A first aspect provides a drive system for rotating a wheel (16) of an aircraft landing gear (10), the drive system including a motor (52) operable to rotate a first drive pinion via a first drive path, and a driven gear (20) adapted to be fixed to the wheel (16). The drive system has a first configuration in which the first drive pinion is capable of meshing with the driven gear (20) to permit the motor (52) to drive the driven gear (20) via the first drive path. One of the first drive pinion and the driven gear (20) comprises a first sprocket (60) and the other of the first drive pinion and the driven gear comprises a series of rollers (36) arranged to form a ring, each roller (36) being rotatable about a roller axis at a fixed distance from an axis of rotation of the first drive pinion or driven gear (20), respectively. Some embodiments include a second drive pinion and the motor (52) is operable to rotate the second drive pinion via a second drive path. Such a drive system is switchable between the first configuration and a second configuration in which the second drive pinion is capable of meshing with the driven gear (20) to permit the motor (52) to drive the driven gear via the second drive path. One of the second drive pinion and the driven gear (20) comprises a second sprocket (62) and the other of the second drive pinion and the driven gear (20) comprises the series of rollers (36). The first drive path has a higher gearing ratio than the second drive path.
