Abstract

1369501 Bearings DEFENCE SECRETARY OF STATE FOR 13 Dec 1971 [5 Jan 1971] 380/71 Heading F2A In a bearing having part-spherical rolling elements, each element has a pair of opposed hollows (which may meet to form a throughbore) and is retained in a cage by projections from the cage which extend within each of the said hollows, the projections being adapted such as to conform with the inner surfaces of the outer extremities of the hollows, such that a film of oil may be formed between the projections and their respective rolling elements to form a hydrodynamic film. The axis of each element may form an angle with the bearing axis, and the dimensions of the hollows and projections may be such as to allow the angle to vary between limits. In Fig. 1, the projections are frusto-conical, and at the limits of angular variation engage co-operating surfaces 16 on the rolling elements to form the said film. In Fig. 3, the projections are convex and the hollows concave.
