    摘要： A bearing assembly for a hinge mechanism is described. The hinge couples a first component and a second component. The bearing assembly includes a ball, an outer ring, a pin and a fastener. The ball includes a bore at a center axis and a convex outer surface. The outer ring includes an outer surface affixed within the second component and a concave surface in rolling contact with the ball to define a primary slip path. The pin is located within the center bore. The pin is affixed to first and second outside surfaces of the fork. The fastener secures the pin such that the bearing assembly permits rotation of the outer ring and the second component along the primary slip path. A secondary slip path is defined by the ball rotating about the pin. The secondary slip path is engaged when rotation about the primary slip path fails.

    摘要： A spherical plain bearing has an outer ring having a concave first bearing surface and an inner ring having a convex second bearing surface slidably disposed to the first bearing surface. The inner ring member also has a third bearing surface for engaging a pin to be mounted in the bearing. At least one bearing surface has a lubrication groove, and one of the outer ring and the inner ring is made from 440 stainless steel while the other is made from a precipitation-hardened martensitic stainless steel. Alternatively, the outer ring and the inner ring may be made from steel and a copper-beryllium alloy. In yet another alternative, the bearing need not have a lubrication groove, but may have a lubrication liner on the third bearing surface. A dropped hinge mechanism for a flap on a fixed wing aircraft has a hinge that includes such a bearing.
