Ringfeder Power Transmission has developed the patent-ending TSCHAN TNR Series engine couplings.

  • Optimizes torsional stiffness and misalignment tolerance across a wide torque range
  • Intended primarily for mobile and stationary diesel-driven powertrains
  • Covers torque range from 160-68,000 Nm (118-50154.23 ft.-lbs.) and speeds up to from 6,000 rpm
  • Consists of aluminum housing and steel hub separated by one or two rows of mechanically-linked, cylindrical elastomer inserts
  • Inserts undergo controlled deformation under shear loads as the coupling transmits torque
  • Fine-tuning torsional stiffness and misalignment tolerance requires only minor changes to composition of the elastomer
  • 'Stiffer' inserts favor torque transmission efficiency and 'softer' inserts favor misalignment tolerance
  • Delivers precisely tuned dynamic stiffness to help solve resonance and vibration problems
  • Weighs about 20% less for a given coupling size compared to traditional rubber motor shaft couplings
  • Offers 15-20% lower cost of ownership due to ease of replacing elastomer inserts
