Drive Arrangement and Drive Arrangement for a Twin-Wire Press

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.
