Rich market experience! Couplings for engines
The engine generates torsional vibrations due to explosions, and if the torsional vibration frequency matches the natural frequency of the drive shaft system, including the coupling, there is a risk of damage to the drive components due to resonance. At KTR, we use a torsional vibration analysis program to propose couplings suitable for your company. KTR's couplings for engines have been adopted by domestic and international manufacturers in construction machinery, road machinery, agricultural machinery, compressors, etc., with a global shipment of over 200,000 units annually.
