Steel disc couplings

Steel disc couplings offer reliable and maintenance-free torque transmission with simultaneous shaft misalignment. The layered lamellas are connected to the hubs or flanges absolutely backlash-free via positive-fit fitting bolts.

How do steel disc couplings work? 

The highly elastic spring steel in the steel disc couplings transmits the torque completely backlash-free. Due to the flexibility of the steel discs used, both angular and axial shaft misalignments can be compensated. The frequently used double-cardanic steel discs couplings also offer the possibility of angular compensation. Two disc packs are connected to each other via a sleeve by two flanges.

The lubrication-free disc sets are considered friction-free. Thanks to the alternating connections between the flange on the hub and the sleeve, the spring steel can compensate for axial and angular vibrations. There are single and double cardanic designs.

Where are steel discs couplings used? 

Steel disc couplings are frequently used for large shaft diameters and drives that require fitting accuracy and transmission without shaft misalignment despite a high power input of up to 280,000 Nm. Examples of the dimensions of the installation locations are wind turbines and ship propulsion systems.  The use can take place in a wide temperature range from about -30°C to 300°C.

The steel disc couplings are used for heavy drives, e.g for applications where positioning is important. Common applications are: Printing machines, pumps, gearboxes, generators, compressors, fans, rollers and paper and textile machines.
