As a result of that shown in the Execution achievable due to favorable bearing load which is essentially across the width of the bearing a uniform, even load distribution achieved relatively long life of the outer bearing 20 become.
- the outer bearing 20 is also for Bearing inspections easily accessible and can be done easily Way, without disassembling the drive motor 2, replaced become.
- the Emergency run bearings can be equipped with one or more sensors Monitoring the respective status, e.g. of Temperature, vibrations and relative movements of the Motor shaft in the sealing gap.
- the supporting part 17 designed with longitudinal ribs 24 can do so be interpreted that he the bearing reactions permanently absorbs and at the same time a desired rigidity having. Accordingly, those in the above described, short-term overloads occurring Shocking moments, which in normal operation too transmitting drive torque many times over exceed, added without damaging the gearbox become.
- sliding bearing drive i.e. with in TatzlagerePSus 10 rotatable and axially displaceable stored drive shaft 5
