Owing to performance superiorities

such as stepless speed regulation and highly effective energy-saving etc.

the hydro-viscous drive(HVD) set has been widely applied in many industrial areas like thermal power plants

etc.. In traditional HVD technology

the HVD set has been designed by using the design method of common wet type clutch coupling. Practice shows that the said method can’t fully meet the requirements in practical engineering. For this combined with theoritical analysis and test

study on design method and calculation fomula for HVD set has been carried out from aspects of load

material

dimensions

shape of oil groove

and thermal balance verification etc.. The new drive set developed can fully satisfy the requirements in engineering practice

obtaining already vast amount of applications.
