THE ADVANTAGES OF HOLLOW SHAFTING IN SHIP PROPULSION

The metallurgical aspects of hollow shafts are reviewed, with references to selected literature (mainly Russian). The conclusions are:--1) With hollow shafts, the elimination of the inner metal zone, most prone to metallurgical defects, leads to better metal-quality control; reduced rigidity of the shafting makes it less susceptible to the effects of cyclic loading and stress concentrations. 2) The boring-out operation is best performed before thermal treatment. The risk of crack formation in the treatment is thereby reduced, metal quality is improved, and the heat treatment is shortened. 3) The economic advantages of hollow shafts include longer life and better reliability, reduction in bearing wearout, smaller power losses through friction and better power transmission characteristics owing to reduced mass of the shafting. 4) These advantages are best realised with relatively large bore diameters (up to 50--60% of shaft diameter).
