ANTIFRICTION BEARING Russian patent published in 2006 - IPC F16C19/22 F16C33/34 

FIELD: mechanical engineering, instrumentation and other industries.

SUBSTANCE: proposed radial-thrust antifriction single-row bearing has inner and split outer races with rolling elements in between made in form of single-step rollers installed in cage. Larger diameter of roller larger step made spherical is in contact only with two roller paths of split outer race of bearing in two point at angle of contact α, and smaller diameter of roller steps is in contact only with two roller paths of bearing inner race in two points to provide rolling of rolling elements both over outer and inner roller paths at constant and equal speed without slipping. Roller path of bearing inner race is provided with ring groove and it forms clearances with larger diameter or roller larger step. Smaller diameter of roller steps is made cylindrical, and it is provided with spherical sections at end faces in contact with roller paths of bearing inner race at angle of contact β.

EFFECT: increased service life of bearing owing to elimination of slipping of rolling elements.
