Abstract
This invention provides an improved aircraft wheel rim wherein a demountable tire bead flange has an annular chamfer within the outboard end of the flange bore, and a split lockring which cooperates to maintain the flange on the wheel rim body has an outer surface chamfer which matches the flange bore chamfer, the angle of the flange bore and lockring surface chamfers being determined by the coefficient of friction of the material comprising the wheel rim assembly such that a compressive wedge-locking load force exists at the chamfer joint as may be imposed by inflation of a rim-mounted tire.
