A planetary gear assembly (14) comprises a planet gear (18) for engaging with a sun gear (12) and an annulus (16) of a planetary gearbox. A carrier (20) is provided for mounting the planet gear (18) within the planetary gearbox, and the carrier (20) comprises two mounting portions (28) one at each axial extent of the planet gear (18). A pin (22) is mounted to the two mounting portions (28) of the carrier (20). The planet gear (18) is mounted about the pin (22) such that the pin (22) defines an axis of rotation of the planet gear (18). A sleeve (24) is arranged around the pin (22), and a bearing arrangement (26) around the sleeve (24) mounts the planet gear (18) to the pin (22) via the sleeve (24). The fit between the sleeve (24) and the pin (22) is an interference fit. |
