    Charateristic

    Air differential shaft is applied mainly to wind shaft, or unwind shaft in special occasions.

    The body of the air differential shaft is made from chrome-plate steel. The friction plate can be made from polyurethane, polyethylene, or rubber to max tension required.

    Differential shaft is mainly used for sub-section equipment that has high requirement on final products and fast speed.The differential ring on it can slip independently. Controlled by the tension system, let the compressed air which has a certain pressure come to axle core, so that it will produce friction torque between the friction parts and the slip ring, and realize constant tension coiling and it will help solve the unwinding problems and material damages caused by uneven thickness and tension of each roll material.

    Feature of Air Differential Rewinding Core Shafts

• Difference in material thickness often arises when unwinding plastic films or other material. In the process of constant winding, this difference can lead to obvious discrepancy in outside diameter of roll, and slight discrepancy in winding torque under this situation.
• After some winding rotation, some rolls may become very tight, and meanwhile, some other rolls may start to loosen, leasing to quality decline in product eventually.
• Our differential air shaft with slipping friction can ensure the highest winding quality, and by keeping proper tension on all rolls throughout the winding operation, materials will not show any problem.
• It works under the theory that friction rings slip constantly in center of air shaft, and to keep same tension, some rings slip faster than others. So tension of each roll can be controlled accurately, and permanent tension can also be gained to guarantee the quality of roll.
• According to different roll diameters, to control air pressure of rubber tube and to stable the tension, a constant air pressure source kept by rotary joint is required.

    Structure

    Central air pressure differential shaft are made of core roll, differential ring, rubber tube, friction parts, sealing rings.

    The body of the air differential shaft is made from chrome-plate steel or hard anodized aluminum. The friction plate can be made from polyurethane, polyethylene, or rubber to max tension required.

    According to the drawing, we can make steel shaft head with different sizes.
