Abstract

PURPOSE: To provide radial and thrust loads with sufficient capacity by specifying spiral groove depth.
CONSTITUTION: In the multiple spiral grooves provided on the surface of a semispherical body 2 on the lower end of a revolving shaft 1; formation of a shallower groove h2 in the neighborhood 2 of a spherical equator than that of a groove h1 in the vicinity 2a of the spherical summit so as to maximize a hrust load capaxity at a point 2a near the top and minimizes to a reasonable extent possible the depth of the groove h2 in the location near the equator. This provides sufficient capacity to thrust load supported mainly by a part close to the spherical summit and to radial load mainly supported by a part close to the spherical equator
