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
