ROLLER BEARING Russian patent published in 2016 - IPC F16C19/22 F16C19/34 F16C33/34 F16C33/58 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to roller bearings. More effective is use of developed bearing as needle roller bearing. Roller bearing comprises inner ring (1) with raceway (3) and outer ring (9) with raceway (11), having single longitudinal axis (6, 12), and row of cylindrical rollers (7) between raceways (3, 11). Raceway (3) of inner ring (1) and raceway (11) of outer ring (9) are opposite to each other and are made in form of a single-sheet hyperboloid surface. Raceway (3) of inner ring (1) and raceway (11) of inner ring (9) are equidistant on entire width of said rings (1, 9), centre of bearing is located on plane that divides width of bearing in halves.

EFFECT: technical outcome is perception of axial load by rolling surface of cylindrical rollers, elimination of variable stiffness of bearing at angle of rotation and provided by its vibration.
