The Planox® clutch PPF - RA is a pneumatically engageable dry friction clutch. The frictionally engaged disc pack is pretensioned by air pressure. When the pressure drops, it is released by pressure springs and thus completely separated. The air is supplied through the gear shaft.

Product information
Technical Data
-
Torque range from 390 Nm to 145,000 Nm
Advantages/properties
- Immediate disengagement in case of overload within fractions of a second
- Radially removable friction element for extremely quick disassembly and reassembly
- Vibration damping through combination with an elastic coupling
- Compensation of shaft misalignment through combination with an elastic coupling
- Complete separation of drive and output sides after shutdown
- ATEX protection possible (Zone 2, 22)
- Smooth operation due to high balance quality
- Operating the extruder at maximum load has no effect on the service life of the coupling
- Integration of the Planox® coupling into the extruder’s process control is possible, as the torque can be variably controlled via air pressure
- Immediately ready for operation again without manual intervention
- Disengagement accuracy of the pre-set torque ± 5% (with run-in coupling and a minimum air pressure of 2 bar)
- System start-up possible either with fully disengaged or engaged coupling; resistant to shock loads
- Significantly reduced production downtime costs
- No change in the torque characteristic of the run-in friction element even after extended storage
