Geislinger Coupling Selection

Technical data for each coupling with ‘multiple blade’ design, depending on the outer diameter of the spring housing section, width of the spring packs, stiffness of the spring packs and directionality code for coupling type, can be selected from the technical data sheets that follow. Technical data for ‘conical blade’ designs are available on request.

Type N, H, U

Geislinger Couplings are available for reversible engines with fixed propellers, non-reversible engines with reversible transmissions, or non-reversible engines with controllable pitch propellers. The couplings can also be used for alternator sets. In order to transmit the same nominal torque
T KN the coupling size increase goes from a non-reversible to a semi-reversible to a reversible coupling. First, based on the application, it is necessary to determine whether a reversible, semi-reversible or non-reversible coupling is required. Fig. 3 shows an example of the different nominal torques
T KN for the same coupling size but different rotation type. See pages 14 - 16 for the limits of permissible elastic vibratory torques of each coupling type.
