ROTARY ROLLING BEARING Russian patent published in 2010 - IPC F16C19/50 F16C33/34 F16C33/58 F16H1/24 

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be implemented at heavy duty bearing units, for example in power, mine equipment, and in machines of sea and river vessels for bearing heavy axial and radial loads. The bearing consists of external (1) and internal (2) rings made in form of conic helical wheels, of arranged between them rotors (3) made in form of conic helical gears with axial openings (5) and of a separator. Similar radii of circumferences create heads of teeth and inter-teeth recesses in end cross section of rings (1) and (2) and rotors (3); in normal cross section heads of teeth and inter-teeth recesses of mating teeth are formed with semi-elliptical profile, angle cosine of screw line rise of which is equal to ratio of small half-axis of ellipse to its big half-axis radial to bearing rotation axis. The separator is mounted on side of foundation of the cone of one of rings (1) and (2) and has internal circular groove (11). Rotors (3) are equipped with journals (4) with axial openings (5). Journals (4) are arranged in groove (11) tied with axial openings (5). The separator is equipped with packing shoes arranged in between-rotor space in pairs enveloping rotors (3); pistons of shoes are installed in the separator, while their between-piston space communicates with groove (11).

EFFECT: increased loading capacity and operation life of bearing facilitating using bearing in machines of smaller dimensions.
