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
- Printing systems: conveyors and in-feeders
- Wood-working systems: saws, wood-working machine, laminators
- Office equipment: electronic copy machines, calculators, fax
machines, coin counters, printers
- Testing systems: lab machines, durability testers, measuring
systems
- Food processing systems: meat cutting machines, cookie making
machines, canning machines, noodle making machines
- 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.
