Definition shaft couplings Shaft couplings are compensating couplings with a backlash free and conformal torque transfer providing high torsional stiffness and a low moment of inertia. According to these requirements, our bellow couplings can be regarded as the ideal solution. More than 25 years, they have proven themselves in thousands of servo drives as being excellent. Jaw couplings with a flexible polyurethan insert can also represent a perfect alternative for different applications because of their product-specific advantages. All shaft couplings have one thing in common, they are all backlash free (also shaft-hub-connection) and flexible to allow the compensation of shaft misalignments. Because of the unique characteristics of the different series, the designer will (almost) always find the best solution within the large-scale of our coupling program. The field of application ranges from highly dynamic feed drives of the axis in machine tools to high performance drives in the general machine tool design. Characteristics: • absolutly backlash free, exact torque transfer • low moment of inertia - high balancing quality • compensation of shaft misalignments - low restoring forces • frictional, easy to fit shaft-hub-connection • metal bellow: max. torsional rigidity, wear free, up to 300°C • elastomer spider: plug-in, oscillation dampening, up to 120°C • large number of types and sizes available (modular system) • precise production - best quality - long life time | |||||||
