caption_attribution_description: English: The Geislinger Damper utilizes steel leaf springs and engine oil. The steel springs are tuned to optimize the natural frequency of a system and engine oil is used to reduce torsional vibrations. Geislinger uses specially developed software to select the specific damper parameters which best protect the engine crank- and camshaft, as well as intermediate and propeller shafts from damage due to critical vibratory loads. The Geislinger Damper provides constant stiffness and very high damping over the damper life, independent of engine room temperature.
context_page_description: The Geislinger coupling is an all-metal coupling for rotating shafts. It is elastic in torsion, allowing it to absorb torsional vibration.
  Unlike some other coupling types, it is not intended to compensate for high radial mis-alignment between shafts, but it can compensate axial misalignments better than elastomer couplings. The coupling may have a small ability to compensate for varying alignment, but if this is needed it is generally done through using an additional coupling in tandem. The coupling also runs at the same speed for input and output shafts, unlike a torque converter.
context_section_description: A related device is the Geislinger damper. This is broadly the same coupling, but both input and output shafts are connected to the same central hub. The massive outer casing is connected to this through similar leaf spring packs, but is free to move torsionally, with damping. It is used as a harmonic damper to control vibrations in shafts.
