Mayr power transmission has therefore equipped the ROBA-DS disk pack coupling for high torques with an easy-to-assemble, positive-locking conical connection which operates at extremely low tightening torques. The five construction sizes in this series cover a nominal torque range from 22,000 to 110,000 Nm.
The handling of large couplings is hard labour, and should therefore be made as easy as possible for the technicians. Furthermore, ease of assembly for large couplings also represents an economic aspect. Many hours and unnecessary costs can be saved thanks to simple and fast assembly. In the case of the ROBA-DS with a conical connection, the flexible disk pack is connected, positive-locking and backlash-free, with attachment components such as hubs, flanges and sleeves. Externally-conical bolts are pulled into the conically-shaped bores of the attachments using tensioning screws, and the collar bushings of the disk packs are tightened. Due to this conical shape, forces are generated which radially, flexibly expand the collar bushings and attachments, and in this way guarantee the backlash-free connection of the disk pack.
Screw tightening torques drastically reduced
The new conical connection reduces the screw tightening torques to a fraction compared to conventional, frictionally locking designs, and this significantly simplifies installation and disassembly. Furthermore, the aggregates do not have to be moved for installation and deinstallation.
ROBA-DS disk pack couplings are extremely robust, resistant to high and low temperatures, and are torsionally extremely rigid and maintenance-free. They transmit the torque backlash-free and without wear, and compensate for axial, angular and radial shaft misalignments. On double-jointed designs, this component permits extremely flexible variations in length between the two disk packs for adjustment to the shaft clearance. Disk pack couplings are well-suited to applications with high torques.
