| Pneumatic style
clutches offer a simple method of adjusting the torque and
provide more accurate torque control than mechanical torque
limiters. Mechanical torque limiters typically vary +/- 10%
but pneumatic clutches vary < 5%. The torque transmitted
by the pneumatic clutch can be remotely adjusted for hard
to access locations. Three-way type manual valves can be
used to engage or disengage the clutch to meet the application
needs.
Pneumatic torque limiters offer “In Flight” torque
adjustability. This feature is used to overcome high starting
torque requirements but allow a lower set torque once the
process equipment is in production. Electronic solenoids
can be used to engage or disengage the clutch on the fly
without shutting down the rest of the process equipment.
Pneumatic clutches can run faster and offer more flexibility
than mechanical torque limiters.
The VOR, POR, PDC pneumatic clutches are sealed and plated
to handle wash-down duty applications. The VOR clutch is
a time proven product that has been around for decades.
The POR clutch is available is six different sizes for
a wide variety of applications. The PDC clutch is a “true
disconnect” clutch that offers a complete torque
disconnect when the air pressure is locked out.
Special designs and configurations with sprockets or couplings
can be produced in short order.
Typical applications
- Paper converting equipment
- High speed processing equipment
- Food processing equipment
- High speed packaging
