An aircraft landing gear (10, fig 1) wheel assembly includes a drive system (50, fig 1) that rotates a drive pinion (60, fig 1) which can be meshed with a ring gear (20, fig 1) to cause the landing gear wheel (16, fig 1) to rotate. A wheel hub assembly 600 includes a wheel 601 having a wheel rim 602 with a ring gear 700 mounted to it. The ring gear is mounted to the rim of the wheel so that torque can be transmitted between wheel and rim. The ring gear is movably mounted to the rim by means of an interface which allows radial movement between rim and ring gear. The interface comprises a plurality of radially extending openings 606 arranged circularly around the ring gear and wheel rim with a plurality of connecting members 607 disposed in and extending between openings in both rim and gear. The arrangement ensures that the ring gear is isolated from any radial deformations induced in the wheel rim.
