The invention relates to a large rotary bearing for the detachable fastening of the upper part of a mobile crane, excavator or similar appliance to the undercarriage, which is fixed with respect thereto, of the appliance, wherein for the transmission of the rotational movement, running surfaces for rolling bodies (10, 11) are provided in each case on the revolving superstructure (1) and on the undercarriage (5), specifically separately for the transmission of axial and radial forces with respect to the bearing axis. The problem is solved in that one bearing ring (4) is detachably or non-detachably fastened to the revolving superstructure (1), and a rotary connection (9) for the revolving superstructure (1) is mounted on the undercarriage (5), wherein the rotary connection (9) is detachably connected, by means of a clamping ring (12) which acts radially outward and inward, to the upper flange (6) of the undercarriage (5). |
