Turbo alternator alignment
Turbo alternator alignment
(OP)
Hi everyone,
In a coupled steam turbine alternator arrangement (3000RPM, 10MVAe) should the DE bearings be slightly lower than the two NDE bearings? That is should both the turbine shaft and alternator shaft be slightly angled downward towards one another at the coupling? If this is so why is it done?
Many thanks to all in advance who answer.

The first steam turbine generators were vertical shaft just like hydroelectric units for that very reason.
In a paperboard making machine the corrugating rolls are larger in diameter in the center so that when under pressure a flat surface is the result. We determine correct pressure by running carbon paper through the rolls at different pressures - the correct pressure results in uniform teeth marks from the rolls.
