648,534. Bearings. FRENKEL, M. S. March 4, 1946, No. 6046/47. Divided out of 648,532. [Class 12 (i)] In order that all the balls or rollers in a double-row angular-contact ball or taper roller bearing may take their share in the radial load the fixed ring and the rotating ring of the bearing are each so arranged as to provide an inner race for one row and an outer race for the other row of balls or taper rollers and one of the rings is so mounted on its seating that it can have angular movement in any plane containing the bearing axis. Under radial load the axial thrusts arising therefrom through the angular-contact disposition and which occur initially in one circumferential half only of each row are offset 180 degrees circumferentially and so cause tilting of the angularly movable ring until all the balls or rollers are under load. As shown, the fixed ring 15 is of U-form in axial section with one limb providing an outer race 21 for one row of balls 19 and the other limb providing an inner race 22 for the other row of balls 20. The fixed ring is of spherical outer form and mounted in a corresponding seating ; means may be provided to prevent its rotating about the bearing axis. The rotary ring provides an inner race 17 for the first row of balls 19 and an outer race 18 for the other row of balls 20.
