Abstract
An improved thrust bearing particularly suited for use in applications wherein the bearing is subjected to cocking loads in addition to thrust loads. The bearing includes first and second relatively rotatable members with one of the members including a thrust collar. The other of the members includes a groove receiving the thrust collar and a bearing surface is interposed between the thrust collar and the groove. The groove, collar and bearing surface are constructed and arranged such that a clearance between the parts may vary in the radial direction to promote the maintenance of an oil film of uniform thickness when wobbling or cocking loads are applied.
