ABSTRACT:
The present epicyclic gear includes a carrier (12), a generally central sun gear (11), an outer annular gear (13) and an intermediary helical planet gear (14) which is mounted on the carrier (12) by a flexible pin assembly (15). The gear further includes a reaction member in the form of a rolling ring (22) at each axial end of the helical planet gear (14) to provide a respective radially inward reaction load onto the planet gear (14) in a sense that the reaction members (22) together resist a twisting moment on the planet gear (14) arising from the tooth loads on that gear.
