SOIL WORKING MACHINE AND SUPPORT STRUCTURE WITH POSITIVE CONNECTION BETWEEN ROTATING WORKING ASSEMBLY AND ITS ROTARY BEARING

摘要

The present invention relates to a soil cultivation machine (10), comprising a support structure (30) and a work assembly (28) rotatably mounted on the support structure (30) about a drive axis (A), the work assembly (28) by means of a first pivot bearing (57) and is rotatably mounted by means of a pivot bearing arrangement (77), the pivot bearing arrangement (77) having a second pivot bearing (76), an assembly-side bearing formation (74a) connected to the working assembly (28) and a structural-side bearing formation (86) connected to the supporting structure (30) both the assembly-side bearing formation (74a) and the structure-side bearing formation (86) in the reference state relative to the second support structure area (30a) are rotatably arranged about the drive axis (A), and both the assembly-side and the structure-side bearing formation (74a, 86) for maintenance, retrofitting and assembly purposes can be axially removed from one another as intended and thus separated from one another According to the invention, it is provided that the assembly-side bearing formation (74a) has a driver formation (88) with a driver surface (88a) pointing in a first circumferential direction (U1) and that the structure-side bearing formation (86) has a driver counter-formation (90) with an in one to the first opposite, second circumferential direction (U2) facing counter driver surface (90a), the movement spaces (92, 94) of the driver surface (88a) and the counter driver surface (90a) overlap around the drive axis (A).
