【 摘 要 】

The bearings' loads of marine shafting are the key aspect to evaluate the operating situation of the whole propulsion system. By using the basic theory and mathematical model of marine shafting alignment, the linear relations between the shafting bearings' positions and the bearings' loads are established and the marine shafting bearings' loads in hot condition is calculated and analysed. Then the ″distortion″ problem of the shafting bearings' loads in hot condition is put forward and discussed by the nominal load bearing. Finally, one important idea of the field on the marine shafting bearings' loads calculation is put forward considering the effects of bearing oil film dynamic response.
