Abstract

834,079. Ball-bearings. ROTOL Ltd. Aug. 29, 1958 [Sept. 13, 1957], No. 28953/57. Class 12 (1). A cageless ball-bearing comprises two rings of balls 21, 22 each ball of each row contacting and spacing two balls of the other row, an outer race 25 having two grooved tracks 27, 28, and a pair of inner race members 11, 12 having ball tracks 19, 20. The ball tracks have a radius of curvature in cross - section slightly greater than that of the balls so that each ball has a single point contact with the outer race and with its associated inner race. The inner races 11, 12 are clamped on the shaft 14 between a ring 16, abutting a shoulder 15, and a nut 18 screwed on the shaft. The clearances are such that a desired pre-loading is achieved. Lubricating - channels 42, 41, 40 are provided.
