AISCO Industrial Couplings, LLC. offers torsionally dampened driveshafts designed to reduce the torsional stress between the drive source and the driven unit. Through use of a torsionally dampened driveshaft resonant frequencies are reduced to below the operating speed, and torque spikes caused by resonance can be brought to within permissible levels. Two designs are available, engine flywheel mounted and integral to the drive shaft. Individual design is based on the application requirements. Due to the special nature of this product an application questionnaire is provided to facilitate a torisional analysis of the complete drivetrain. Typical applications include dynamometers, boat drives, construction machines etc.
