Triple Rolling Element Layer Tapered Roller Axial Bearing.

A redesign of the Cageless, Multilayered, Full Complement Axial Tapered Roller Bearing concept. Intended for axial loads only. The rollers are truncated conical rollers. The tapered rollers in the middle layer of rolling elements are perpendicular to the shaft median axis.The profile of the trough in the bearing shell which the rollers travel through is in the shape of an only slightly tapered trapezoid tipped over on its side, with its smaller and larger bases describing arcs which are concentric with the bearing shaft's median axis.Problems solved by this bearing are:1. Uneven loading of the bearing's tapered rollers, in the case of bearings with a single layer of rolling elements, due to minute differences in the size or radius of the rollers owing to manufacturing tolerances.2. Sliding contact friction between adjacent or consecutive rollers, in the case of a full complement tapered roller bearing, or between the rolling elements and their cage, in the case of a caged tapered roller bearing.
