Sažetak

Hydrodynamic coupling is a power-transmitting device with no stiff kinematic relation between the shafts of its basic parts (pump and turbine impellers) and no torque transformation. It has been used in various driving mechanisms due to its certain advantages, especially in transient working regimes of machines. Nevertheless, no sufficient attention has been devoted to the study of a braking period of such driving mechanisms, either in research papers or in practice. The existing few papers analyse only the experimental results concerning the braking period. The paper outlines a combined graphical and numerical method which enables the survey a of driving system operation in either steady-state or transient working regimes. The method is based on mechanical characteristics of all relevant driving system components defined either experimentally or in manufacturers’ catalogues. The method is explained through defining the braking period duration on an example of a typical belt conveyor driving mechanism with a hydrodynamic coupling. The importance of the proposed method for the practice, and certain limitations of its application are pointed out.
