Abstract EN
The shafting of large steam turbine generator set is composed of several rotors which are connected by couplings.
The computing method of shafting with different structure under specific installation requirement is studied in this paper.
Based on three-moment equation, shafting alignment mathematical model is established.
The computing method of bearing elevations and loads under corresponding installation requirements, where bending moment of each coupling is zero and there exist preset sag and gap in some couplings, is proposed, respectively.
Bearing elevations and loads of shafting with different structure under specific installation requirement are calculated; calculation results are compared with installation data measured on site which verifies the validity and accuracy of the proposed shafting alignment computing method.
The above work provides a reliable approach to analyze shafting alignment and could guide installation on site.
