The present invention relates to a disk-type rail apparatus for forward and backward rotation, which is mounted on an apparatus that needs to perform complex forward and backward motions in addition to rotation action. In order to operate smoothly even under weight pressure of moving a large, heavy object which becomes eccentric and unbalanced during transportation, the present invention comprises multiple balls connected with chains on upper and lower sides configured in disk shape, and more than two ball circulation systems for supporting the plurality of balls even for forward/backward motion and rotation. The disk-type rail apparatus for forward and backward rotation comprises a rail module which has the built-in ball circulation systems at the upper and lower ends thereof and is actuated along a rail module guide during forward/backward motion and rotation. In addition, the disk-type rail apparatus is configured to enable smooth forward/backward motion by ring driving members installed at both ends of the rail module. Therefore, the disk-type rail apparatus includes straight and disk-type rail modules for rotating 360° while moving along various rails such as a curved rail and the like. Furthermore, the rail apparatus can be electrically driven when connected with an electric motor. |
