ANALYSIS OF STRESS DISTRIBUTION ALONG THE TOOTH CONTACT LINE OF LARGE MARINE REDUCTION GEARS AND MEASUREMENT OF STRESSES IN ACTUAL SHIPS

In marine reduction gears of large width, "end tooth bearing" may occur because of shafting misalignment (due to installation error or hull deformation) and gear shaft deformation (torsional, bending, or thermal). These factors interact with one another, making it difficult to take them into account for the quantitative determination of the distribution of tooth-root stresses. The Authors present a new analytical method of calculating load distribution and root stresses, in which "end tooth bearing" is taken into consideration. Results obtained with this method, in calculations for the bull wheel in a 400,000-dwt (45,000 hp at 85 rpm) tanker, are compared with the stress distribution along the contact line of the tooth root as measured with strain gauges.
