Flexible Compression Sleeve Coupling type (ELCO) from RENK
ELCO Torsionally Flexible Coupling effectively absorbs shocks and suppresses vibrations which arise during operation. Moreover, it takes up radial and angular misalignments of the connected shafts and allows a certain amount of longitudinal displacements.
The installation of a correctly designed ELCO coupling guarantees the safe transmission of forces and offers extensive protection of the connected machine shafts against vibration damage. The ELCO coupling has a proven track record in tens of thousands of drive systems thanks to its adaptable construction and high-quality design.
The torque is transmitted by means of coupling bolts and compression sleeves of high grade elastomer
The compression sleeves are made of high quality, reinforced elastomer, which ensures the extraordinary performance range of the ELCO Couplings compared to most other couplings. Placement on a bolt circle with a diameter as small as possible provides a great twisting angle. Several differently deep groove profiles at periphery of the sleeves provide progressive torsion spring characteristics. Due to the elasticity of the profile sleeves, only minor restoring forces occur on the bearings.

Notes on storage of ELASTOMER products
The compression sleeves must be protected against UV radiation and heat, as otherwise changes in the vibration behaviour may occur (DIN 7716). These factors accelerate the aging process by modifying the spring characteristics and the damping properties of the sleeves.
