Abstract: An earth working machine includes support structure and a working assembly mounted on the support structure so as to be rotatable about a drive axis. An assembly-side bearing configuration is connected to the working assembly and a structure-side bearing configuration is connected to the support structure. The assembly-side bearing configuration includes a driver configuration having a driver surface facing in a first circumferential direction and the structure-side bearing configuration includes a driver counterpart configuration having a driver counterpart surface facing in a second circumferential direction opposite to the first, the movement spaces of the driver surface and of the driver counterpart surface about the drive axis overlapping one another.

Abstract: An earth working machine encompasses a machine body having a machine frame and a drive configuration rotationally drivable relative to the machine frame around a drive axis (A). It further encompasses a working apparatus (32) for earth working to which the drive configuration is releasably connected in drive torque-transferring fashion for rotation together, the drive configuration projecting from an axial end axially into the working apparatus (32) and the working apparatus (32) being retained on the drive configuration, against axial displacement relative to the drive configuration, by an accessible central bolt arrangement having a bolt axis collinear with the drive axis (A). Provision is made according to the present invention that the earth working machine encompasses a bolting moment bracing arrangement (82) which is connected or connectable in bolting moment-transferring fashion to a bolt component, helically movable relative to the drive configuration, of the bolt arrangement, and which comprises a bracing region (82e, 82gf) that is embodied for bolting moment-bracing abutment in a bracing bolting direction against a counterpart bracing region (84b, 84c), the drive configuration being embodied to be driven to rotate, in a rotation direction codirectional with the bracing bolting direction, while the bracing region (82e, 82f) is in abutment against the counterpart bracing region (84b, 84c).

Abstract: A replaceable milling drum for an earth working machine includes a milling drum tube and a protrusion structure fixed to the milling drum tube. A bearing stem protrudes from the protrusion structure axially away from a drive axial end of the milling drum tube. The bearing stem has an outer surface including at least first and second cylindrical bearing surfaces axially spaced from each other, a furthest one of the cylindrical bearing surfaces from the drive axial end having a smaller diameter than a next furthest one of the cylindrical bearing surfaces from the drive axial end, the bearing stem having a central opening therethrough co-axial with the drive axis.
