ESCODISC HIGH-SPEED SERIES DISC TYPE COUPLINGS
CHARACTERISTICS OF THE ESCODISC HIGH-SPEED SERIES COUPLINGS
Multidisc pack subassembly version
Application-wise customized with weight-optimized flanges
Anti-spark and anti-fly (Optional)
Balanced for high rotation speeds of up to 22,000 rpm
Disc couplings are of an all-metal, non-lubricated design and are torsionally stiff. The torque is transmitted by means of discs, which are alternatively mounted (on the same bolt circle) to the drive and driven flange of the disc pack assembly.
The misalignment capacity depends on the pack thickness, the disc material, the amount of drive bolts and the free span of the material between the drive bolts.
The total torque capacity depends on the disc pack thickness, total number of drive bolts and their bolt circle.
Disc couplings will in most cases have two flexible elements and a spacer. As all parts are positively connected, this disc coupling ensures good inherent balancing properties.
The Escodisc High-Speed series, also called high-performance disc couplings, are used in high-power/high-speed applications. The couplings design may differ as a function of the application and the characteristics of the machines to be connected and hence full data are required for coupling design.
Balancing is required as well as optionally compliance with API 671. These couplings have provision for accomodating angular and parallel misalignments and have provisions for accomodating thermal growth of the machine shafts.
The Escodisc High-Speed series couplings are robust and reliable and meet the specific requirements of the various rotating machines.
