Description Tech Overview Related Products

Made of advanced composite materials to eliminate tonality challenges of next-generation big onshore wind turbines.

The new GESILCO® Silentshaft is made of advanced composite materials. The optimized torsional stiffness characteristics of the shaft isolate the drivetrain systems from vibrations and enable fine-tuning the frequency behaviour of the drivetrain. It is our newest solution for mitigating noise, vibration and harshness for onshore wind turbines.

Compared to steel sunshafts, the GESILCO® Silentshaft is significantly more efficient in mitigating tonalities, as shown in the graph. The GESILCO® Silentshaft perfectly complements Geislinger’s product range for mitigating parasitic loads and NVH in onshore wind turbines.

The GESILCO® Silentshaft Coupling is installed between the sun pinion and the generator rotor. The advanced fiber composite flange provides a direct connection to the generator rotor. The product is characterized by not being an ‘add-on’ solution, as it is substituting an existing element, significantly enhancing its performance.
