Title:
BALL BEARING
Document Type and Number:
Japanese Patent JPS5477851
Kind Code:
A
Abstract:
The bearing comprises two rows of balls which circulate between two pairs of raceways. The raceways associated with each row of balls comprise two toric bearing surfaces which are substantially symmetrical with each other with respect to a plane perpendicular to the axis of rotation of the bearing. An elementary section of each of these bearing surfaces, in a plane containing the axis of the bearing, is at least substantially part-circular and has a radius slightly larger than the radius of the balls, and is substantially symmetrical with respect to a straight line parallel to the axis of the bearing and subtends a center angle exceeding about 120 DEG . The arrangement is such that the orientation of forces of contact and the location of zones of contact between the balls and the raceways vary in accordance with the direction of application of the load to which the bearing is subjected.
