FIELD: mechanical engineering. ^ SUBSTANCE: seal comprises flexible round seal body provided with the central axis A and at least one flange passing radially outward and connected with the inclined sealing edge through the pivot. The pivot has reduced thickness in comparison with the thickness of the flange and edge which is provided with the first and second converging sides that leads to the enlarged rim provided with inclined first and second peripheral surfaces. The peripheral surfaces are converging toward the outer edge that lies in the bearing plane P parallel to the central axis. ^ EFFECT: enhanced reliability. ^ 14 cl, 2 dwg |
