| Rotation is transmitted through a central disc that slides over the tenons on the hubs under controlled preload conditions to eliminate backlash. Discs and hubs are available in different materials and configurations to suit different applications. These couplings provide generous radial compensation and easy maintenance. |

| The fin-couplings DINAL., belonging to series "GEL" are usually used for the connection of tachogenerators, encoders, contactors, motors, measuring instruments and for every application where a constant rotational velocity in the four qua-drants is required and where an absolute torque rigidity is required, even when the shafts coupling is not perfectly lined up. Projected according to DIN 740, these couplings can bear angular, radial and axial misalignments, without causing stress on the connected shafts, thanks to their peculiar construction. Their special construction and the used materials allow to use them within a tem-perature of - 30 °C + 200 °C. |

- very low mass inertia torque
- easy for assembly
- a small space for assembly
- balanced
- special design available on request
The size of the coupling should be selected so that the nominal torque is greater than the highest torque to be regularly transmitted. (Acceleration or load torque). The shaft misalignments must not exceed the previously mentioned values. Otherwise this will limit the working life of the coupling. |

These torsionally stiff couplings serve for the connection of two shaft ends compensating for angular and parallel misanlignment as well as axial backlash. They are used for the backlash-free and precise angular drive of:
-potentiometers / angle encoders
-resolvers / transducers
-low powered drives
The mounting of the coupling onto the shaft ends is achieved by two set screws each with one cup point per hub. In the case of a smaller than indicated size of bore, an accurate transmission or peak-torque is no longer guaranteed. Larger borings can be supplied on request. |

For more than 25 years we have successfully been supplying shaft couplings for ships and other non-positive shaft couplings in various designs for the construction of motors and gearboxes and plant engineering. Our range includes designs with shaft diameters of up to 250 mm. Our customers benefit from the many years of experience in this field.
Rigid couplings from WEISS are available as sleeve couplings and flange couplings, both in a steel or saltwater- proof design. In addition, we also offer flywheel flanges as joining elements for diesel engines. |
