Maintenancable Differential Slip Ring Key Type Steel With Chrome
Coating
Description
Easy disassemble differential slip ring is very maintenancable, and
it is separate parts for the differential shaft and can replaced separately. The amount of slip exactly compensate for the difference in
speed, thus it can control the tension of each roll precisely,
which ensure the winding quality. The slippage rings are controlled
to slip at a certain slip torque (torque), and the amount of slip
exactly compensate for the difference in speed, thus it can control
the tension of each roll precisely, which ensure the winding
quality.

Final tension you need have to check with engineer or machine
manufacturer
Principle
- The 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.
- The differential ring on differntial shaft can slip independently,
it is the main part for differential shaft which is with tension
adjustment.
- Controlled by the tension system, make the compressed air which has
a certain pressure come to shaft core, so that it will produce
friction torque between the friction parts and the slip ring.
Features
- 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.
Advantages
- The use of differential shaft ring improves the stablity of the
slitting machine,espceially for high speed machine.
- The differential shaft combined by differntial rings can make the
accuracy of the winding and the automation.
- Differential shaft ring to wind or unwind precious materials, metal
foil and special paper roll, can greatly reduce the cost of
production.
Application
- Slitting machine
- Coating machine
- Cutting machine
- Printing machine
- Compounding machine
- Paper making machine
- Bag makeing machine
- Embossing machine
