SPHERICAL ROLLER BEARING Russian patent published in 2004 - IPC

FIELD: mechanical engineering; antifriction bearings.

SUBSTANCE: in proposed spherical roller bearing containing outer race with spherical path, inner race with three toroidal paths, three rows of barrel-shaped rollers installed so that axis of rollers of middle row is parallel to axis of bearing, and axes of rollers of extreme rows are inclined through angle to bearing axis and diameter of middle path is less than diagonal size between middles of extreme paths and cylindrical belts are made on inner race between middle and extreme paths. Bearing contains two cages per three rows of rollers.

EFFECT: increased load capacity and speed of rotation.
