A rotary supporting mechanism comprises a pair of cylindrical or spherical hollow bodies arranged one inside the other, there being a quantity of liquid between the two bodies, one of the bodies remaining fixed while the other is movable rotationally and in an up-and-down direction with respect to the body which remains fixed, the liquid between the bodies absorbing loads applied to the movable body. The movable body may be rotatable about a horizontal or vertical axis or, in the case of a sphere, may be rotatable in all directions. Bearing elements may be provided between the two bodies as well as seals to prevent the escape of the liquid. |
