Due to their low torsional rigidity and good damping properties, highly flexible Siemens couplings are excellently suitable for connecting non-uniformly working machines. They are preferably used in periodically exciting systems, such as drives with internal combustion engines or piston compressors. Because of the large elastomer volume, comparably large shaft misalignments can be compensated.
Owing to its low torsional stiffness and damping property the ELPEX coupling is very well suitable for connecting machines with a considerably non-uniform torque characteristic. Types with a fail-safe device between the flexible rings ensure emergency operation if the flexible rings are destroyed. ELPEX couplings are available in 12 sizes for torques from 1,600 Nm up to 90,000 Nm
The ELPEX couplings made from grey cast iron (GG-25)or steel are available in nine sizes for torques up to 90,000 Nm. The flexible rings are made of high-quality natural rubber in which the fibre inserts, which transmit the torque, are vulcanized.
