1.Description of differential air shaft
1). Introduction
The central air pressure differential shaft is a type of shaft with tension adjustment. 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.
The central air pressure differential shaft can meet the requirements of high-speed, error in material thickness, multi-stage tension control, high precision requirement on tension control, uniformity on the winding end . It’s ideal for double shaft and Center Coiling slitter.
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
Applicable to the rewinding or slitting of packaging materials such as web, plastic sheet, aluminum foil, PVC, plastic film, insulating material and so on. It is an ideal equipment for fine cutting materials.
3.The relationship between air pressure and torque
(single slip differential unit)
Air pressure | Torque |
0.1MPa | 0.81N.m |
0.2MPa | 1.35N.m |
0.3MPa | 1.58N.m |
0.4MPa | 1.92N.m |
0.5MPa | 2.25N.m |
0.6MPa | 2.42N.m |
0.7MPa | 2.62N.m |
0.8MPa | 2.93N.m |
4.Why choose us?
1). Technical advantages
Clamping reliable, low malfunction rate, the unique design makes it easy to dismount, and can replace the friction keys conveniently with no affection to the rotation accuracy.
Frame fixed good, small gap, high precision, to ensure the slitting machine can operate in high-speed.
2).Material advantages
A.Friction key materials are patented formula, good consistency of dynamic and static friction coefficient, less affected by temperature ,high wear resistance and long service life.
B.Adopting high quality 40 chrome as the shaft ,which greatly improve the bearing capacity of the whole shaft.
C.The overall quenching and tempering treatment improve the wear resistance and corrosion resistance,which make it possible to use in a variety of environment.All bearing are imported from Japan,which help extend the overall life.
3). Quality advantages
We have the during the whole production from the very beginning to the end and our principle is to make sure each roller is qualified.
Steel ball won't drop and the shaft will not bent,even been used 2years.
