SOME FACTORS IN MARINE GEARING FOR CLASSIFICATION PURPOSES

The paper gives a brief history of the evolution of the Rules of Lloyd's Register of Shipping up to the adoption of the basic I.S.O. formulas for design, and analyzes the main defects in both steam turbine and oil engine gearing over the past seventeen years. With this background, the values applicable to the factors for surface loading and tooth bending strength are discussed. Finally, the manufacturing tolerances and installation practices, particularly with regard to external effects, necessary to obtain the conditions at the mesh appropriate to the permissible loadings, have been outlined. I.S.O. notation has been used in the paper and, where the coefficients in Lloyd's Register's published Rules differ, the correlation has been indicated.
