ABSTRACT:
A hemispheric bearing apparatus for preventing deformation of a hemisphere occurring when a shaft is push-fitted into a shaft inserting hole formed at the center of a hemisphere in a hemispheric bearing which supports a thrust load and a radial load at the same time, the apparatus including a pair of hemispheres fitted into a fixing shaft to face each other around a spacer, and having a first section disposed opposite to the spacer and a second section contacted with the spacer; a first deformation preventing portion formed in the first section at a predetermined distance around the fixing shaft to prevent deformation of the hemispheres; and a second deformation preventing mechanism formed in the second section at a predetermined distance around the fixing shaft to prevent deformation of the hemispheres.
