    摘要： The present invention relates to an interchangeable unit (28) for material-removing work on a subsoil (U) starting from ground surface (A), the interchangeable unit (28) being designed for operational physical and functional coupling to a machine frame (12) of a road construction machine (10), the interchangeable unit (28) comprising:



    a housing (30),
    a removal tool (32), which is mounted on the housing (30) so as to be rotatable about a working axis (R) and of which a circumferential section protrudes from a working opening (30c),
    a drive belt pulley (62), which is rotatably mounted on the housing (30) and is able to be coupled to a drive belt (58),
    a transmission gear unit (76), which transmits torque and rotary motion from the drive belt pulley (62) to the removal tool (32) by reversing the direction of rotation, at least the axis of rotation (P62) of the drive belt pulley (62) running at a distance from the working axis (R).




    According to the invention, a working shaft assemblage (74) penetrates a housing wall (30d) of the housing (30), the working shaft assemblage (74) connecting the removal tool (32) with a working gear component (70) situated on the side of the housing wall (30d) facing away from the removal tool (32) for equidirectional joint rotation, the transmission gear unit (76) being situated between the drive belt pulley (62) and the working gear component (70).

    摘要： A milling attachment for a work machine includes a frame including first and second frame side walls A motor mounting plate is removably mounted on the second frame side wall. A milling drum includes first and second mounting flanges. A first drive motor is mounted on the first frame side wall and includes a drive end connected to the first drum mounting flange by a plurality of threaded fasteners. A second drive motor is mounted on the motor mounting plate and connected to the second drum mounting flange by a stab-in non-threaded connector.

    摘要： An earth working machine includes a 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.

    摘要： A retention system for retaining a milling drum to a driveshaft of a milling assembly. The driveshaft is powered to drive the milling drum about an axis. The retention system includes a retention member coupled to the driveshaft between a first position and a second position. In the first position, the retention member restricts a disengagement between an engagement surface of the driveshaft and a mating surface of the milling drum, inhibiting a release of the milling drum from the driveshaft along the axis. In the second position, the retention member provides clearance for the disengagement of the engagement surface and the mating surface, facilitating the release of the milling drum from the driveshaft along the axis.
