CONVEYING DEVICE, MOVING SIDEWALK, ESCALATOR, AND CONVEYOR

摘要

PROBLEM TO BE SOLVED: To provide a practical conveying device which employs a means different from a conventional conveying device. SOLUTION: The conveying device comprises a driving sprocket 2 rotated and driven by a motor 1, a driven sprocket 4 of which rotation and driving are driven from the driving sprocket 2 via a driving chain 3, and a main sprocket 6 on which the main chain 7 rotating integrally with the driven sprocket 4 is wound. The number of teeth of driven sprocket wheel 4 is smaller than the number of teeth of the driving sprocket 3. The number of teeth of the main sprocket 6 is the same as that of the driving sprocket 3. The farthest point of the driving chain 3 wound on the driven sprocket 4 from the center of the driven sprocket 4 synchronizes with the farthest point of the main chain 7 wound on the main sprocket 6 from the center of the main sprocket 6. The nearest point of the driving chain 3 wound on the driven sprocket 3 from the center of the driven sprocket 4 synchronizes with the nearest point of the main chain 7 wound on the main sprocket 6 from the center of the main sprocket 6.
