Steel Material Ball Type Slitting Machine Differential Shaft 50mm Width Round Edge
Differential shaft, also known as slip shaft or friction shaft, is used as the winding shaft and special rewinding shaft for slitting machine. The purpose is to use the slipping on each differential ring on the shaft to make multiple constant tension rolls on the shaft.
The differential shaft is composed of a plurality of differential rings, and the friction torque of the differential ring is controlled by the air pressure, so that the tension of the inner roll to the outer roll will be constant. The shaft can make a neat ends, and the material tension is constant.
Air 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.
Feature of Air Differential Shaft
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.
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.
