Examination result:
For the examination a calculation of traction sheave shaft including shaft-hub-connections was carried
out by IFF ENGINEERING & CONSULTING GmbH. The result was that the traction sheave and the
shaft-hub-connections were designed according to the maximum load data.
An installation free of stresses and an unmovable mounting of the bearings in each direction is
presupposed. The machine frame and the points of force introduction have to be designed regarding
construction and strength appropriate to the forces imposed on the bearings.
