DFE - QFE Series (HC Series Multi Disc Clutches)

Torque range: 1400~36500Nm
There are two types: Single Disc Types and Dual Friction Plate Type. They are large size air clutches and are designed for highest torque capacity and low inertia.
Typical Applications: Forging Machines, Foil Making Machines, Paper Machines, Ball Mills, Coil Machines, Conveyor Machines,a variety of Presses.

Feature:

• Simple Piston & Cylinder Structure
  There is neither influence of centrifugal force, nor torque fade caused by the wear of friction facing.
• O-Ring Used for Sealing
  Repairing cost to the tube type clutches is lower and the maintenance is easier.
• Structure of Disc
  As the centrifugal force does not affect even at high speed, a stable torque is generated.
• Fin Structure
  Fin structure provides a better cooling effect, resulting in generating a stable torque.
• The Splined Sliding Part
  The smooth movement makes a better release of disengagement.
• Adoption of Multi-Split Friction Facing
  The better airflow increases cooling effect. The material of friction facing is made of non-asbestos.
• Low Inertia
  The most suitable engagement at high speed is realized.

Air passing through the rotary seal and bracket is fed into the cylinder sealed by O-rings, and pushes the piston. The pressure plate is bushed by the piston and moves, and then contacts the disc with both sides of the friction facings. The friction facing plate & housing, the disc & hub move smoothly through spline. Air being exhausted, the return springs disengage the clutch.
