Exploded view showing the structure of a TMB coupling

High-performance flexible coupling in modular system; 11 sizes with diameters from 300 mm to 900 mm; hub–claw ring and standard attachments can all be combined in each size

Plug-in coupling with modular design, flexible elements can be radially replaced simply by moving the retaining ring; power transmission through pressure on stressed elastomers

Physical and technical parameters

  • Torque (T) 6,000 Nm to 1 million Nm
  • Speed (n) 7,600 to 2,500 min–1
  • Stiffness (C/T) approx. 80 to 100
  • Permissible ambient temperature: Polyurethane –20°C to +80°C
  • Electrically insulating

Manufacturing and material

TECMEN couplings in the TMB series are used for instance in power stations, cable cars, compressors and cement mills.

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.)
