Abstract

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.
