Popis: In this paper a rocket motor turbine-pump reduction gear system is analyzed in regard to Hertzian gear tooth contact stresses and times of contact. It is found that the Hertzian contact stresses vary from approximately 100,000 psi to 200,000 psi. The times of contact vary from three to eight microsec. Some observations regarding the correlation between contact times and gear failures are made. It is indicated that it may be possible to establish design limitations on the contact times to insure satisfactory gear operation. Sample calculations for evaluating each of the typical quantities found in the tables are included.
