What are the advantages of using fluid couplings?
• Wear-free power transmission because of absence of mechanical connection between the input and output elements. • No-load start-up of motor, irrespective of machine load and motor peak torque utilized for machine acceleration. • Motor selection to operating HP rather than starting loads. Saving on energy cost and capital cost. • Simple control of maximum or limiting torque by easy variation of oil filling. • Added protection for motor and driven machine by limiting torque to a predetermined safe value • Automatic unloading of prime mover in case of any sustained overload, by blowing-off of fusible plug on coupling, thus draining out oil. • Automatic synchronization and load sharing in case of multi-motor drives. • Effective dampening of shocks, load fluctuations and torsional vibrations. Helpful in improving the drive duty conditions in machines subjected to shock loads, frequent load changes, startups and reversals. Reduced fatigue on transmission components / elements. • Smooth and
