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.
