FIELD: machine building.SUBSTANCE: rotary support device comprises main bearing element. In main housing cavity on main bearing element are installed current conducting unit of rotation, azimuthal housing encoder, azimuthal drive driven pulley and two bearing taper bearings, on which azimuthal housing is movably installed, on which azimuthal inching motor is installed, on which shaft azimuthal drive driving pulley is installed, which is connected with azimuthal drive driven pulley by flexible transmission. Azimuthal housing comprises two axes pipes on lateral sides, whereon elevation housing is movable installed on bearings, in cavity of which elevation component elements are arranged, made with possibility of angular positioning of, at least one, external attachment in preset elevation direction, wherein on one axis pipe elevation drive driven gear is installed, and on other axis pipe elevation housing encoder is installed. To elevation housing elevation inching motor is attached, on which shaft elevation drive driving pulley is installed, which is connected to elevation drive driven pulley by flexible transmission, arranged on pipe axis and rigidly attached to elevation housing frame. Elevation housing is made with possibility to accommodate external attachment thereon, as well as with possibility of rotational movement in space elevation sector relative to azimuthal housing.EFFECT: higher accuracy of positioning, simplified design.16 cl, 9 dwg |
