Abstract

541,459. Bearings. BRITISH TIMKEN, Ltd., HILL, A. W., and TREEN, R. Nov. 11, 1940, No. 16310. [Class 12 (i)] A thrust or radial- andthrust bearing has conical or barrel-shaped rollers with convex ends making line or point contact with a concave surface on the bearing rib when unloaded and full surface contact when loaded. In a thrust bearing, Figs. 1, 2, the cone of the rollers 1 has an apex at b on the axis a of the bearing and their end surfaces 3 have a centre of curvature at o lying on the cone axis within the apex. Each race ring 2 has a rib 4 with a thrust surface 5 curved transversely about the point o and longitudinally about the point b, thus forming line contact at x,and clearances 6 which are taken up on loading. The transverse curvature may be about a point on the cone axis nearer than point o or beyond point b so as to give a point contact at the root or lip of the rib 4. The rib 4 may be formed on one race ring only, the other ring having an innersurface inclined to or parallel with its outer surface. In a radial- andthrust bearing, Fig. 7, the cone apex b lies on the bearing axis a and the surfaces 3, 5 are curved about point o on the cone axis within its apex, the longitudinal curvature of surface 5 being about the point b. In both types, the roller ends may be parabolic instead of spherical.
