Embodiment Construction
[0043] exist figure 1 In the preferred prior art embodiment shown, the bearing arrangement comprises a drum 101 rotationally fixedly connected to a drive shaft 103 via a suspension 121 . A suspension 121 is located at the first end 110 of the drive shaft, said first end being conical in this embodiment. The conical shape is chosen in order to minimize the weakening of the drive shaft 103 by the notch effect. Each direct diameter transition of the drive shaft 103 is referred to as a weakening phenomenon under load leading to local load peaks, and these load peaks correspond to the notch effect. The drive shaft must bear not only the total load and torsional force of the drum 101, but also the power generated by the rotating motion of the drum and / or the drive shaft 103 itself. These dynamics introduce cyclically fluctuating alternating bending stresses into the shaft that can lead to fatigue failure, and it is known that fatigue failures of this type usually start from struct...
