<P>PROBLEM TO BE SOLVED: To provide a rotation system capable of efficiently rotating a rotating shaft utilizing the weight of a load (heavy object) while suppressing a resistance due to the weight of the load provided to the rotating shaft. <P>SOLUTION: Bearings are inserted into both ends of the rotating shaft, respectively, and the outer peripheral rings of the bearings are fixed to the rotating shaft. A fixed shaft fixed to the inner peripheral ring of each bearing projects from the inner peripheral ring of the bearing, and the fixed shaft is fixed to a base. The inner peripheral ring of the bearing is positioned on the fixed side, and the outer peripheral ring of the bearing is positioned on the rotation side where the rotating shaft is rotated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
