Abstract:
A vibration damper for a bearing located between two rotatable shafts, said bearing comprising an inner race and an outer race said outer race being located adjacent a bearing housing, an axially extending oil entry surface positioned radially inwardly of the radial outer surface of said outer race and axially adjacent one end of said bearing, the outer surface of said bearing outer race forming a clearance between itself and the bearing housing suitable for the ingress of a film of oil directed from said oil entry surface, a weir positioned at the axially opposite end of said bearing, said weir being radially inward of said bearing outer race and said oil entry surface whereby in use the radial height difference therebetween provides a pumping force thus supplying a film of oil between the bearing outer race and its casing.
