Roller bearing arrangement

Abstract

The invention is directed to a roller bearing arrangement comprising two rings arranged mutually concentrically and at least regionally inside each other, and comprising a gap between these rings, so that they are rotatable in opposite directions about an imaginary axis at the center of the rings and approximately perpendicular to the ring plane, wherein disposed in the region of a gap portion situated between the rings and surrounding the axis of rotation at an approximately constant radius is at least one raceway for at least one row of rollers, each having a rotationally symmetrical shape and rolling displacingly between the rings, each of which rollers, when the rings and the rollers are at the same temperature, has at least one point or region of contact with the raceway portions on each of the two rings, so that the radial and/or axial clearance between the two rings is equal to zero or at least is negligibly small; and comprising a mechanism for compensating for temperature-induced radial changes in the cross section of the raceway for at least one row of rollers, so that the compressive stress exerted on the rollers and/or the clearance between the rings remains approximately constant, even in the case of a temperature difference between the rings and/or between them and the rollers.
