Nickel Plated Steel Material Slitting Machine Differential Shaft
Width 49
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.
