SOME CONSIDERATIONS ON SHAFT ALIGNMENT OF MARINE SHAFTINGS

A review of some of the more dominant external factors that influence the shaft alignment in service is given. The effects of draught alterations, thermal influences, eccentric propeller thrust, thrust bearing tilting and bearing flexibility are discussed. Some further aspects of shaft alignment are also dealt with, such as the connection between requirements to alignment versus whirling vibrations, the importance of considering angular deflection between shaft and aft stern tube bearing, and alignment in dock. It is concluded that these factors must be taken into consideration in the design analysis if one is to ensure an approach to the concept of "optimum alignment".
