The coupling transmitsthe power by means of the kineticenergy of the fluid, mostly oil, circulating in a closed working chamberbetween the pump wheel on theinput shaft and an identical turbinewheel, connected to the output shaft.The fill level of operating fluid canbe varied during operation between“full” and “drained”, thus enablingexact and dynamic speed control ofthe driven machine across a widerange when the coupling operatesagainst different load characteristics.This operating range depends onthe load characteristics (torquerelative to speed) and the requiredcontrol accuracy.Simplified cross section:12345678Pump wheelTurbine wheelHousingScoop tube housingOil sumpOil circulation pumpScoop tubeWorking oil cooler45

Flow-controlled turbo couplings are only used for special applica-tions such as when extremely high torques or speeds are required. Smaller Type R4 propellers or pro-pulsion units with an electric drive do not require turbo couplings. For Type R4 propellers with diesel engine propulsion, clutch coup-lings must be used instead of turbo couplings.
The geared variable speed coupling controls the speed of the driven machine precisely, quickly and repeatably within the required control range. Unique characteristics The reliability of the geared variable speed coupling is 99.97 %. Hydrodynamic power transmission is wear-free. The compact driveline with the geared variable speed

The second type is also used to separate the driven machine from the driver, like a clutch, without losing the advantages of the first group. The third group, variable speed fluid couplings, is the subject herein.
