Ball Type Steel Material Differential Slip Ring Diameter 74mm 12
Balls
Description
The differential shaft ring consists of a plurality of slip rings,
which can overcome the problem of unwinding and material damage.
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.
Principle
1). The differential shaft is a type of shaft with tension
adjustment. The differential ring on it can slip independently
.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, and
realize constant tension coiling.
2). 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 . It’s ideal for double shaft and Center Coiling
slitter.
3). The differential shaft can be divided into two types: pneumatic
locking type and mechanical locking type.
4). Differential shaft are made of core roll, differential ring,
rubber tube, friction parts, sealing rings.
and the differential rings are most important and main part of the
differntial shaft

Advantages
The advantages of using differential shaft ring
1. The use of differential shaft ring improves the speed of the
slitting machine .
2. The accuracy of the winding and the degree of automation.At the
same time,it shortens the preparation time and achieve the
humanized operation. In particular for polyester thin materials
which have poor tensile resistance and big difference in
thickness.The use of differential shaft ring can reduce the
difficulty of winding.
3. Besides, using differential shaft ring to wind or unwind
precious materials, metal foil and special paper roll, can greatly
improve the production yield, reducing the cost of production.
Application
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, Frame fixed good, small gap, high precision, to ensure
the slitting machine can operate in high-speed.
