FIELD: machine building.SUBSTANCE: invention relates to roll bearing for radial support of the suspension stop, which rings are made out of forged metal plates and have enveloping geometry. Roll bearing contains lower ring (26) creating lower race, top ring (24) creating top race, and balls (28) rolling over top and bottom races ay that ensuring relative rotation of the top (24) and bottom (26) rings around the geometrical axis (XX) of rotation of the bearing. The bearing geometry is such that in any section plane, where the geometrical axis (XX) of bearing rotation is located, the bottom race creates bottom circular arc (C) specifying the bottom centre (O) of axial curvature, the top race creates the top circular arc (C) specifying the top centre (O) of axial curvature, at that bottom and top centres of curvature are located on the inclined geometrical axis (ZZ), that creates with the geometrical axis of rotation (XX) a inclination angle (?) from 5 to 65°. In the section plane, where the geometrical axis of bearing rotation is located, the top circular arc (C) has two ends specifying opening angle (?) over or equal to 80° and tangential in bottom plane (P) perpendicular to the axis of rotation in some bottom tangential point (U) specifying together with the nearest end (I) of the bottom circular arc a section of bottom circular arc (C) with opening angle (?) over or equal to 10°.EFFECT: design of roll bearing with increased strength and radial forces resistance.13 cl, 2 dwg |
