Product Description

Product Description

Differential air shaft Description 

  Differential shaft applied mainly to wind shaft, or unwind shaft in special occasions.

The body 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.

Differential air shaft Feature

   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.

Our Advantages

1. Inflatable job a short time, separated from the lug type air 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 air shaft parts, each part in its construction  fixed specifications, can exchange it with, it is convenient.
6. The lug type air 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.

5. Maintenance is simple, use a long time: a single film blowing machine air shaft parts, each part in its construction Jieyou fixed specifications, can exchange it with, it is convenient.
6. Air shaft order guide   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 film blowing machine air shaft inlet gas,when the gas nozzle is mounting,the out diameter of the top of the 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.

FAQ

1.When can I get the quotation?
We usually quoted within 24 hours after receiving your inquiry. If you are very urgent to get the price, please call us or tell us in your email, so that we can regard your inquiry priority.

2.How should I place an order?
Please let us know the model number based on our specs for powder clutch, powder brake, air clutch, air brake, electromagnetic clutch, electromagnetic brake and safety chucks, other transmisson parts.
For air shafts,air adapter please show us your drawing, or let us know your request, and then we will provide you drawing for confirmation.

3.What's your MOQ basis?
Normally, we don't have MOQ request, except the customized mini clutches/brakes.

4.What about the lead time for production?
Honestly, it depends on the order quantity and the type of our products. For powder clutch, powder brake, tension controller,which is about 3-5 days. For safety chucks, air shafts which need about 15-30days.

5.What is the term of shipment ?
We can arrange with EXW, FOB, CIF…etc. You can choose the most convenient one or cost-effective way.
