TECMEN couplings in the TMN series

TMN coupling – 3d rendering
Exploded view showing the structure of a TMN coupling

Flexible coupling in a modular system; 10 sizes with diameters from 340 mm to 1040 mm; hub I–hub II, flywheel–hub II, connecting piece–hub II and standard attachments can all be combined in each size

Plug-in coupling in two-piece design; flexible elements and bolts are replaceable; power transmission through pressure on stressed elastomers

Physical and technical parameters

  • Torque (TKN) 5,000 Nm to 340,000 Nm
  • Speed (n) 3,400 to 1,300 min–1
  • Stiffness (C/T) approx. 80
  • Permissible ambient temperature:
    polyurethane (standard) –20°C to +80°C
    polyurethane (HT): –20°C to +120°C (150°C)

Manufacturing and material

  • Machined cast blanks
  • GGG hub (part I and II)
  • bolts high quality steel, grinded
  • flexible polyrurethane elements (PUR/Vulkollan®)

TECMEN couplings in the TMN series are used in hydro power plants, steel works, rotors, blowers and general engineering.

The standard questionnaire on design of torsionally flexible couplings you can fill in as form for combustion engine as drive unit or for non combustion drive units or download as pdf. As an additional recommendation we hint on a neat conversion program that’s worth its weight in gold! (Thanks to Josh Madison.)
