Abstract:
IMPROVED DESIGN OF ROLLING BEARING comprising:an inner race ring having radially directed wall sections; an outer race ring having radially directed wall sections, being radially spaced from said inner ring; rolling elements radially between said outer ring and the inner ring, said each rolling element having an axis of rotation; said rolling elements having predetermined shape lines of contact on said radially directed wall sections, between the rolling elements and the inner and outer race rings, said lines of contact including four points of contact for radial and axial normal loads and four additional points of contact for axial and radial overloads; said four lines of contact for radial and axial normal loads being defined by tangents having an average angle with respect to said rolling element axis of rotation greater than 50Â°; said race ring wall sections being elastically deflectable to permit said balls to contact said four additional contact points during overloads.
