• In a crowned gear pair, which is employed to prevent end-tooth b~bearing, the load distribution in the tooth trace direction is elliptical. This paper describes the effects of crowning on the antiseizure capacity of a gear base oil. The experiments were carried out by two-cylinder tests at high specific slidings comparing the results under uniform bearing. The antiseizure capacity of the gear base oil in the tests with crowned cylinders was higher than that in the tests with uncrowned cylinders. Though the contact width in the axial direction at seizure became small and the Hertzian stress at seizure became high as the radius of crowning was decreased, the radius of crowning hardly affected the antiseizure capacity. Finishing the surface roughness finely is an effective means to decrease the friction coefficient and to increase the antiseizure capacity of the gear base oil in the higher range of sliding velocity.
