摘要:
A drive arrangement for an agricultural machine, especially a field chopper, has a motor driven gearbox (3) that is connectable at a drive-end to at least one drive motor (1). At least one first hydraulic pump (8, 8′) is provided to feed at least one hydraulic motor (14), (17) to drive a working mechanism of a machine. A belt pulley (4) of a belt drive (5), especially for driving a chopper drum (10), is coupled with the gearbox (3). A release clutch (7), with an input-side first clutch element (36) and an output-side second clutch element (37), is also coupled with the gearbox (3). The first clutch element (36) is drivingly connected to the motor driven gearbox (3). The second clutch element (37) is drivingly connected to the belt pulley (4). The second clutch element (37) is non-rotationally connected to a drive shaft (38) to drive the at least one first hydraulic pump (8, 8′).
摘要:
A device which attaches an agricultural implement (2) to a tractor (1), and in addition, establishes a driving connection between the power take-off shaft of the tractor and the drive of the implement has, for this purpose, a drive unit (8) which includes two bevel gear angle drives (9, 10) arranged one above the other. One of the drives (9, 10) is firmly connected to the drawbar of the implement with the other one connectable to the lower steering arm of the tractor by an attaching stirrup (12). The attaching system allows the tractor and implement to pivot relative to one another around a vertical axis (25), a transverse axis (26) and a longitudinal axis (27). To achieve pivotability relative to the drive unit (8) around the longitudinal axis (27), the attaching stirrup (12) is supported by a sleeve (47) on a flange housing (39) which is arranged coaxially relative to the first connecting journal (20) of the drive unit (39) thereby achieving an improvement in the transmission of towing forces.
摘要:
A drive assembly has two bevel gear angle drives (9, 10) for driving an agricultural implement (2) via a tractor power take-off shaft. The assembly has a pivot bearing (11) which effects a pivotable connection between the two bevel gear angle drives (9, 10). To improve the bearing conditions between the two bevel gear angle drives (9, 10) the two housings (22, 23) of the bevel gear angle drives (9, 10) are provided with bearing sleeves (24, 25). The bearing sleeves (24, 25), in the fitted condition, project into the interior (34) of a housing (23), to reduce the axial distance between the two connecting journals (13, 16) associated with the bevel gears (41, 43) which engage the bevel gears (49, 57) arranged on the connecting shaft (67), thus improving the force receiving conditions.

A connection arrangement between a feed roller and a gearbox of a field chopper has a first shaft (25) with a central bore (26) that is rotatingly supported around an axis of rotation D, in a gearbox housing (30). A second shaft (32) is connected to a feed roller. The second shaft (32) is rotatingly supported around the axis of rotation D. The second shaft (32) has a central bore (33) that is aligned with the central bore (26) of the first shaft (25). A connecting journal (37) rests in the central bore (26) of one of the two shafts (25). The connecting journal (37) is form-fittingly connected to the central bore for torque transmission. It is axially displaceable along the axis of rotation D between a connected position where it is inserted into the central bore (33) of the other of the two shafts (32), and a released position, where it is pulled out of the central bore (33) of the other of the two shafts (32). The connecting journal (37) is form-fiftingly connected, in the connected position, to the other of the two shafts (32).

An agricultural machine, especially a field chopper, has a carrier vehicle (28) with an intake unit (18) mounted on and arranged to the carrier vehicle (28). The intake unit has an intake gearbox (19) and at least one feed roller (21, 21′; 24, 24′) to guide the harvested goods to a chopper drum (10). The intake gearbox (19) is drivingly connected to that at least one feed roller (21, 21′; 24, 24′). The intake unit (18) is at least partially detachably attached to the carrier vehicle (28). A hydraulic motor (17) is mounted on and arranged to the carrier vehicle (28). The hydraulic motor (17) drives the intake gearbox (19). The hydraulic motor (17) has a drive shaft (40) that is detachably and drivingly connected to an input shaft of the intake gearbox (19).

摘要:
A gear drive has a drive housing (1, 2) with a driveshaft (3) exiting the drive housing (1, 2) through a bore (10). The driveshaft 13 is rotatably supported in the drive housing (1, 2) around an axis of rotation X—X. A connecting shaft (7) is arranged inside the drive housing (1, 2). The connecting shaft (7) is connected in a rotationally fast way to a drive gear (35). A torque limiting coupling (4) is arranged inside the drive housing (1, 2). The input end of the torque limiting coupling (4) is connected to the driveshaft (3). The output end of the torque limiting coupling (4) is connected to the connecting shaft (7). The driveshaft (3) and the connecting shaft (7) are supported relative to one another by a radial bearing (30). The gear drive ensures that the driveshaft (3) and the connecting shaft (7) can more easily accommodate bending moments and transverse forces.
