Title:
RADIAL ROLLING BEARING WITH MEANS FOR ALIGNMENT
Document Type and Number:
WIPO Patent Application WO/2018/097979
Kind Code:
A3
Abstract:
A bearing device for supporting a shaft to rotate relative to an outer hub includes: an annular outer race mountable within an interior bore of the hub, the outer race including an inwardly facing radial groove sized to receive a rounded bearing element; and an annular inner race mountable to an outwardly curved exterior surface of the shaft. The inner race includes an outwardly facing radial groove sized to receive the bearing element, the respective radial grooves of the inner and outer races together forming an annular raceway to retain the bearing element when the bearing device is assembled. The inner race further includes an axially convex surface along an innermost diameter of the inner race, the convex surface shaped to directly engage the exterior surface of the shaft when mounted thereto, such that the inner race remains in contact with the shaft while accommodating radial deflection of the shaft.
