Steel Material Ball Type Slitting Machine Differential Shaft 50mm Width Round Edge

    Summary

    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.

 

    Application

  1. Printing systems: conveyors and in-feeders
  2. Wood-working systems: saws, wood-working machine, laminators
  3. Office equipment: electronic copy machines, calculators, fax machines, coin counters, printers
  4. Testing systems: lab machines, durability testers, measuring systems
  5. Food processing systems: meat cutting machines, cookie making machines, canning machines, noodle making machines
  6. Others: speed reducers, electroplating machinery, physics and chemistry machines, paper-making machines, pulp processing machines.

    Component

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.

The advantages of CBB products

 

A. Trustworthy company and long history

Established in 1995, CBB Ruian Chuangbo is one of the biggest machinery spare parts manufacturer in East China. Bigger than 20,000 square meters factory and more than 180 employees. 

 

B. Hight quality material for the core shaft and spare parts

The body of the differential shaft is made from steel or stainless steel.We will check the surface roughness,straightness, dynamic balance,cylindricity and so on to make sure it's qualified to use.

 

C.Surface Treatment

Blacking,polishing,anodize,chrome plating,zinc plating,nickel plating,tinting.
The overall quenching and tempering treatment improve the wear resistance and corrosion resistance,which make it possible to use in a variety of environment.

 

D. Quality control

We have the quality control system during the whole production fromthe very beginning to the end and our principle is to make sure each shaft is qualified.
