Abstract
A drive arrangement comprising a roll with a roll bearing, a bearing housing and a motor, wherein the bearing housing of the roll bearing is connected to a frame or a foundation and a drive torque of the motor can be transmitted to the roll. The motor is connected to the bearing housing and a reaction torque of the motor can be transmitted into the bearing housing. This allows avoidance of mechanical stresses introduced into the roll with good accessibility of the rolls.

1-10. (canceled)
A drive arrangement comprising:
- a roll (1,10) rotatable about an axis (7);
- a roll bearing (3) with a bearing housing (4) connected to a frame (16) or a foundation, the roll bearing (3) mounting the roll (1, 10) whereby a drive torque of the motor (6) can be transmitted to the roll (1,10);
- and
- a motor (6) indirectly connected to the bearing housing (4) of the roll bearing (3) at least via a gear unit (8), whereby a reaction torque of the motor (6) can be transmitted into the bearing housing (4) of the roll bearing (3), wherein
- the drive torque of the motor (6) can be transmitted to the roll (1,10) via the gear unit (8) and a coupling (11) arranged between the gear unit (8) and the roll bearing (3), the coupling (11) comprising a first coupling element (13) and a second coupling element (14) with the first coupling element (13) being connected to the roll (1,10) and the second coupling element (14) being connected to the gear unit (8), and
- a third coupling element (15) connects the first coupling element (13) and the second coupling element (14), wherein an alignment of the gear unit (8) deviating from the axis (7) of the rotatable roll (1,10) can be compensated by the third coupling element (15).
A twin wire press, comprising a first roll (1) rotatable about a first axis (7) for driving a first clothing and a second roll (10) rotatable about a second axis (7) for driving a second clothing, comprising:
- a roll bearing (3) with a bearing housing (4) connected to a frame (16) or a foundation, the roll bearing (3) mounting the first roll (1) whereby a drive torque of the motor (6) can be transmitted to the first roll (1);
- and
- a motor (6) indirectly connected to the bearing housing (4) of the roll bearing (3) at least via a gear unit (8), whereby a reaction torque of the motor (6) can be transmitted into the bearing housing (4) of the roll bearing (3), wherein
- the drive torque of the motor (6) can be transmitted to the first roll (1) via the gear unit (8) and a coupling (11) arranged between the gear unit (8) and the roll bearing (3), the coupling (11) comprising a first coupling element (13) and a second coupling element (14) with the first coupling element (13) being connected to the first roll (1) and the second coupling element (14) being connected to the gear unit (8), and
- a third coupling element (15) connects the first coupling element (13) and the second coupling element (14), wherein an alignment of the gear unit (8) deviating from the axis (7) of the rotatable first roll (1) can be compensated by the third coupling element (15).
