Engine Coupling Optimizes Torsional Stiffness

Inserts undergo a controlled deformation under shear loads as the coupling transmits torque.

Ringfeder Power Transmission (Westwood, NJ) has developed a patent-pending engine coupling that optimizes torsional stiffness and misalignment tolerance. The new TSCHAN TNR coupling is intended primarily for mobile and stationary diesel-driven powertrains. Additional features include:

  • An aluminum housing and steel hub separated by one or two rows of mechanically-linked, cylindrical elastomer inserts.
  • Inserts that undergo a controlled deformation under shear loads as the coupling transmits torque. 
  • Fine-tuning the torsional stiffness and misalignment tolerance via minor changes to the composition of the elastomer—stiffer inserts favor torque transmission efficiency and softer inserts favor misalignment tolerance.
  • The ability to tune dynamic stiffness to help solve resonance and vibration problems.
  • A torque range from 160 to 68,000 Nm.
  • Speeds up to 6,000 rpm.
