9.14 Attachment of Drive Elements
For all attachments of drive elements to the drive shaft, such as
• gearboxes
• couplings
• gear pinions
it is imperative that the following notes are observed.
Generally, overdetermined bearings are to be avoided by all means when
connecting drive elements. The tolerances inevitably present in such
cases will lead to additional forces acting on the motor bearing and
perhaps also to a distinctly reduced lifetime of the bearing or to a
progressive bending fracture or fatigue fracture of the motor shaft.
