ment. Hydrodynamic couplings, often also called fluid or Fttinger couplings, are used as starting couplings in drives with high mass moments of inertia of the driven machine. In drive technology very often flexible, positive couplings, which may be designed to be torsionally rigid, torsionally flexible or highly flexible, are used. Torsionally rigid couplings are designed to be rigid in peripheral direction and flexible in radial and axial direc - tions. The angle of rotation and torque are conducted through the coupling without phase shift. Torsionally flexible couplings have resilient elements usually manufactured from elastomer materials. Using an elastomer material with suitable ShoreA hardness provides the most advantageous torsional stiffness and damping for the application. Shaft misalignment causes the resilient elements to deform. Highly flexible couplings have large-volume (elastomer) resilient elements of low stiffness. The angle of rota-tion and torque are conducted through the coupling with considerable phase shift.INTRODUCTION /4 FLENDER STANDARD COUPLINGS | INTRODUCTION 4 4 5 5 6 6 7 7 8 8 9 9 1 1 1 1 1 1 1 1 Shaft couplings Couplings Clutches rigid flexible friction positiveClamp couplings Flanged couplings Mechanism couplings Hydrodynamic couplings Magnetic couplings Friction couplingsClutchesexternallyoperatedrotation directioncontrolled Safety couplingstorque-controlled Centrifugal clutchesspeed controlled Freewheel clutches Overrunning clutches Torsionally rigid Torsionally flexible Highly flexible Gear couplings All-steel membrane couplings Universal-joint couplings Parallel-crank couplingsSteel-spring couplings Pin-and-bush couplings Pin couplings Rubber element couplingsRubber-tire couplings Rubber-disk couplings Rubber spacer ring couplings G_MD1_EN_0a /5 FLENDER STANDARD COUPLINGS | INTRODUCTION 4 4 5 5 6 6 7 7 8 8 9 9 1 1 1 1 1 1 1 1 OUR COUPLING GROUPS AT GLANCE -EUPEX, RUPEX and -BIPEX Flexible Couplings Flexible Flend
