Geislinger Component
Geislinger Coupling
Torsional elastic, high-damping steel spring coupling with hydrodynamic oil damping, tailored stiffness and damping, ATEX certified, for marine propulsion, gensets and other drivetrains.
Description
The Geislinger Coupling is a torsional elastic, high-damping steel spring coupling with hydrodynamic damping properties. Steel leaf springs transmit torque and provide elasticity, while pressurized oil provides hydrodynamic damping. Stiffness and damping can be adjusted individually to shift torsional critical speeds and damp engine-excited torsional vibrations.
Key features
- Tailor-made, compact and lightweight design; integration in flywheel or gear possible
- Constant performance with no aging; resistant to heat and oil
- Long service life and long intervals between overhauls
- Low axial reaction forces
- ATEX certified for potentially hazardous areas
- Can be combined with Geislinger Flexlink, GESILCO® composite couplings or SILENCO® couplings for higher misalignment or acoustic requirements
- Gear Integrated Coupling variant for integration in gearboxes
Technical data
- Torque range: virtually unlimited
- Twist at nominal torque: 50 - 300 mrad
- Dimensionless damping factor: 0.2 – 0.5
- Ambient temperature: -10°C to 120°C
Applications
Marine propulsion (elastically or rigidly mounted 4-stroke engines, gensets, hybrid PTO/PTI drives, z-drives and azimuth thrusters), power generation, off-highway, wind power and industrial drivetrains. Geislinger also offers torsional vibration calculation, commissioning and measurement analysis.
