Abstract
PURPOSE: To enable to test the balance of a large and heavy body of rotation by holding the axial direction of a static pressure spherical bearing upright and by projecting a hard axis from the center of the sliding part of the bearing in the axial direction while fitting the body of rotation to be tested horizontally.
CONSTITUTION: Body 1 of rotation which is large in size in the radius direction, small in length in the axial direction and made of a flat hollow barrel is fitted horizontally to static pressure spherical bearing 3 with fitting jeg 2. Sliding part 3A of this static pressure spherical bearing 3 has a convex spherical surface and supporting part 3B in a stationary state has a concave spherical surface; the both engage with each other and their axial direction is held upright to obtain a thrust supporting function in both directions of an axial thrust and radius-directional thrust. Then, hard axis 4 made of an elastic body is projected penetrating supporting part 3B in the center from the center of sliding part 3A in the axial direction. Such a constitution enables the adjustment of sufficient balance states of all rotary parts except the body of rotation to be tested and the balance of even a large body of rotation can be tested.
