ROLLER BEARING Russian patent published in 1999 - IPC

FIELD: mechanical engineering, in particular, production of bearings for instruments used in aviation, and spindle bearings for machine tool manufacture. SUBSTANCE: roller bearing has roller bodies coming into contact with one ring on roller races positioned at double contact angle of β₁ 1 = 40 deg - 140 deg to rolling surface of roller bodies, and with other ring on roller races positioned at double contact angle of β₂ 2=60 deg-180 deg to rolling surface of roller bodies. Bearing of such construction may be used in mechanisms with low and high rotational speed. EFFECT: wider operational capabilities and enhanced reliability in operation. 5 cl, 1 dwg
