DMUCC - series
CHARACTERISTICS OF THE ESCODISC DMUCC SERIES COUPLINGS
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 and is hence often used at motor speeds without additional balancing.
The Escodisc DMUCC series has a close coupled design with a split spacer. It's high torque, bore and it's misalignment capacity makes it an ideal maintenance-free alternative for close coupled gear and elastic type couplings and can be modified in such a way that replacement of gear and elastic couplings is possible without modifications to an existing installation. Its split spacer design allows a disconnection of two machines and replacement of the disc pack without any axial displacement of the connected machines. The Escodisc DMUCC series is the ideal solution for applications up to 29,600 Nm (and larger upon request) with its high degree of natural inherent balance up to size 85.
