RADEX®-N - steel multiple-disc clutch
Backlash-free and torsionally rigid steel multiple-disc clutch
The all-steel RADEX®-N coupling employs discs made of high-strength, rust-free spring steel. These allow pronounced shaft misalignments to be compensated for with low restoring forces. Due to its all-steel design, the RADEX-N® can be used with drives at temperatures of up to +280°C.
The disc shape, optimized using the finite element method (FEM), guarantees very high levels of torque transmission and torsional rigidity with maximum shaft misalignment compensation.
Highlights
- Single and double-cardan versions
- Maintenance- and wear-free
- High misalignment compensation capacity
- Rated torque up to 280,000 Nm
- Suitable for temperature range of up to +280 °C
Structure and function
The disc packs made of high-strength, rust-free spring steel and their connection to hubs and intermediate pieces form the heart of this steel multiple-disc clutch. Special fit screws enable a combination of friction and form fit via the alternate screwing onto the hub and intermediate pieces.
