SOIL WORKING MACHINE AND METHOD FOR PRESSING A WORKING DEVICE OF A SOIL WORKING MACHINE

摘要

Tillage machine (10), such as a road milling machine, a recycler, a stabilizer or a surface miner, the tillage machine comprising: a machine body (13) with a machine frame (12) and one relative to the machine frame about a drive axis (A) for rotation drivable drive formation (46), the drive axis defining an axial direction, a working device (32; 132; 232) for tillage, to which the drive formation (46; 146; 246), transmitting a drive torque, is releasably connected for common rotation, wherein the working device extends axially between a drive axial end (32a) and a securing axial end (32b) opposite the drive axial end and radially surrounds the drive formation of the tillage machine, the tillage machine comprising a release component (88) as a screw arrangement which can be screwed relative to the drive formation, the release component a has: a cooperation formation (88a) for engagement with a propulsion formation (74e) of a centering component (74) of the working device, a contact section (88d) for exerting axial force on the drive formation and a torque transmission formation (88b) for torque-transmitting engagement with a torque - Tool, wherein the centering component has a central passage (74d) through which the drive formation can be reached, the centering component having the axial distance in the direction away from the drive formation, the propulsion formation, by means of which the release component with axial force support on the centering component in the direction of Drive formation is advance; and method for pressing a working device of a tillage machine.
