Air expanding friction air shaft for adhesive material
1.Description of differential air shaft
1).Introduction
Differential air 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 andit will help solve the unwinding problems and material damages caused by uneven thickness and tension of each roll material.
2) Classification
A.Pneumatic locking type
B.Mechanical locking type
3) Structure
Central air pressure differential shaft are made of core roll, differential ring, airbags, friction parts, sealing rings.

2.Application of differential air shaft
A.The applicable Machine
It is used for slitting machine,coating machine,cutting machine,printing machine,compounding machine,paper making machine,bag makeing machine, embossing machine and so on .It can greatly improve the working efficiency and the quality of products.
B.The applicable Material
Differential air shaft has been widely used in plastic film including electronic, capacitor, battery film, plastic wrap, packaging, composite film, metal foil such as copper foil and aluminum foil, paper and pvc sheet.
3.The advantages of our products
1). Hight quality material for the base shaft and spare parts
The body of the differential shaft is made from steel or stainless steel.We will check the surface roughness,straightness, dynamic balance,cylindricity and so on to make sure it’s qualified to use.
The friction plate can be made from polyurethane, polyethylene,or rubber.They has good consistency of dynamic and static friction coefficient, less affected by temperature ,high wear resistance and long service life.It’s good to realize max tension required.And we can customize according to customer’s drawing or special requirement.
2).Surface Treatment
Blacking,polishing,anodize,chrome plating,zinc plating,nickel plating,tinting.The overall quenching and tempering treatment improve the wear resistance and corrosion resistance,which make it possible to use in a variety of environment.
3). Quality control
We have the quality control system during the whole production fromthe very beginning to the end and our principle is to make sure each shaft is qualified.
