HEAVY OBJECT TURNING APPARATUS

摘要

The present invention provides a technique of a heavy obj ect turning apparatus that is compact, that is enabled to reduce the distance between the center of gravity of a heavy object s and a pivot positioned on an axis, and that is configured so that a turning arm and a drive unit has a length in the direction of an axis passing through the pivot around which the heavy object is turned. A control unit 12 fixes a support base 13 onto a stand 3. An orthogonal axis reduction gear 6 serving as ananterior reduction gear is disposed on the front surface of a posterior reduction gear 26. The orthogonal axis reduction gear 6 has a configuration in which an output shaft is on an axis A of a planetary gear type reduction gear serving as the posterior reduction gear, and in which an input shaft is perpendicular to the axis A . The orthogonal axis reduction gear 6 is constituted by a hypoid reduction gear or a worm-geared reduction gear. A motor 16 is disposed on the bottom surface of the orthogonal axis type reduction gear 6. The bottom portion of the motor 6 is interposed between the gear 6 and the stand 3. The motor shaft of the motor 16 is connected to a gear portion including the hypoid gear or a worm wheel of the orthogonal axis reduction gear 6.
