Product Description of Air Differential Rewinding Core Shafts

The ball type pneumatic 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 or hard anodized aluminum. The friction plate can be made from polyurethane, polyethylene, or rubber to max tension required.

To meet our customers’ special requirements, according to the drawing, we can make steel shaft head with different sizes.

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 air bag and to guarantee tension, a constant air pressure source kept by rotary joint is required.

1.5"/2"/3"/4"/5"/6"/12" Lug Type And Leaf Type Air Expanding Shaft(Aluminum or Steel)

Lug Type And Leaf Type Air Shaft Expanding Core Shaft -- 1.5"/2"/3"/4"/5"/6"/12" 

Introduction of lug type/leaf type air shaft

The leaf type air expanding shaft is applicable to winding and unwinding shaft of the related machines in coating ,cutting ,printing ,compounding ,paper making, bag making, plastic items, specially the occasion of the high-efficient roundness required or surface winding and unwinding of the paper tube. Moreover,leaf type air expanding shaft also can improve efficiency and quality of the products.

Structural Features of lug type/leaf type air shaft

The leaf type air expanding shaft utilizes the aluminum tiles with flexible scalability, deploying high quality rubber bladder and rapid aerating and exhausting gas nozzle with good sealing effect and long service life,air shafthas removable shaft with simple maintenance.

Advantages of lug type/leaf type air shaft

1. Inflatable job a short time, separated from the leaf type air expanding shaft and place the paper tube just three seconds to inflate and deflate, nor do they need any parts sub negligent shaft side that is able to work closely with the paper tube bite.
2. Paper tube placement simple: inflatable and deflated operation, mobile and fixed any position paper tube in the axial plane.
3. Carrying heavy: May be the actual needs of customers, to determine the size of the shaft diameter, and the use of high strength steels hard to make it carry the weight increase.
4. Economic efficiency: shaft design for a particular function, for thick, thin, wide, narrow tubes have encountered all kinds of paper of all applications.
5. Maintenance is simple, use a long time: a single leaf type air expanding shaft parts, each part in its construction has fixed specifications, can exchange it with, it is convenient.

Ppaer tube inner dia	Φ38.1mm	Φ76.2mm	Φ152.4mm	Φ304.8mm
Shaft dia before expanding	Φ37mm	Φ74mm	Φ150mm	Φ302mm
Shaft dia after expanding	Φ40mm	Φ79mm	Φ156mm	Φ308mm

Order guide of lug type/leaf type air shaft

Users should specify type,dimension,the position of the gas nozzle,and the tolerance of the important size of the top of shaft.If the air shaft inlet gas,when the gas nozzle is mounting,the out diameter of the top of the leaf type air expanding shaft should be more than 35mm;All formal drawing of overall dimension should be provided.After the confirmation of both sides,we will start production.
