ABSTRACT:
A flexible spring bearing comprising a substantially cylindrical configuration with an arcuate portion being disposed circumferentially about the cylindrical configuration. The arcuate portions may be convexly curved outward or concavely curved inward. Although many combinations are possible, the preferred embodiment is a concave portion at one end and a convex portion at the other end. A thrust cap is incorporated to be inserted over the convex portion thereby evenly distributing the applied pressure throughout the flexible spring bearing and also regulating the flexibility of the convex portion. Furthermore, a main bearing race and thrust race are incorporated to be contiguous to the end of the concave portion. The main bearing race along with the cylindrical configuration rotates, via a bearing means, upon the thrust race. The bearing means may be an annular protrusion disposed concentric with the cylindrical configuration. The bearing means is protected from corrosion and dirt by various configurations of annular skirts and walls which form a channel with the bearing means located therein. The channel may be prepacked with a lubricant, thereby creating a hydraulic floating relationship between the main bearing race and thrust race. A visual indicator may be included to provide a means to measure the amount of surface wear of the bearing means on the thrust race.
