A bearing rotary device includes support elements installed on the basement frame, centering elements and mechanism of rotation of the plate frame. The support elements are arranged as circular support rods, for instance, two, that are concentrically fixed on the lower surface of the plate frame and the support rollers mounted in circle on basement frame with uniform circular separation. The centering elements are arranged as a circular centering rod mounted on the lower surface of the plate frame, concentrically with respect to the circular support rods, and centering rollers kinematically connected to it. Besides that, the mechanism of rotation of the plate frame is arranged as a roller chain that is fixed in circle on the outer cylindrical surface of the plate frame and being in engagement with the sprockets placed symmetrically, those are brought into rotation with individual drives. |
