Flexible Couplings

Spiroflex

• Highly elastic shaft coupling for torque of up to 928 kNm
• Alignment compensation
• Excellent damping capability

Flexible solution for shaft connections

The elastic rubber elements were completely optimized significantly enhancing the coupling’s reliability and performance. The most significant feature of the coupling is its rubber high torsionally flexible elements. Moreover, the coupling compensates center mismatch, axial as well as angular misalignment of the shafts and machinery elements, to be connected (engines, gearboxes, generators etc.) within a predetermined tolerance range.

The coupling is especially suited for use in diesel engine propulsion systems and installations where torsional vibration must be considered.

Various rubber hardness grades effectively address the natural frequencies arising in the respective drive system.

SPIROFLEX KS couplings shift resonance (torsional vibration) between the natural frequencies of the system and the exciting frequencies of the driving and driven machines. Due to their high damping qualities they also reduce the residual vibration amplitude and thus protect the valuable plant. Additionally, the rubber elements isolate structure-borne noise effectively.

Sizes KS 100 to KS 370 are designed with ring elements EJN while sizes KS 390 to KS 530 are fitted with four EJK segments which together form a ring element.
