SPHERICAL BALL BEARING AND HINGED INSTRUMENT CONTAINER EQUIPPED WITH THE SAME Russian patent published in 2006 - IPC F16C19/02 B64D47/00 

FIELD: instrument building, preferably in avionics, in particular, spherical bearings.

SUBSTANCE: spherical ball bearing has inner race with two annular parts protruding to the outside and carrying convex and concave spherical roller surfaces, outer race with convex and concave spherical roller surfaces, and set of balls housed within separator. Spherical roller surfaces of both races have single center arranged on axis of ball bearing, outside thereof. Outer race is equipped with two inwardly protruding annular parts carrying convex and concave spherical roller surfaces with radii of spheres equal to radii of respective spheres of convex and concave spherical roller surfaces of inner race. Protruding annular parts of both races are made circumferentially separated into at least three staggered sectors so that sectors of protruding annular parts of one of races are inserted into gaps between respective adjacent sectors of protruding annular parts of other race. Container is equipped with such a ball bearing.

EFFECT: wider available useful volume of container and improved dimension and weight characteristics.
