THE INVENTION RELATES TO A HYDRODYNAMIC COUPLING AND TO A METHOD FOR OPERATING A HYDRODYNAMIC COUPLING

摘要

The invention relates to a hydrodynamic coupling (1) comprising a pump impeller (3) as a first impeller (2) and comprising a turbine impeller (5) as a second impeller (2). The pump impeller (3) has pump impeller blades (13) connected to a main part of the pump impeller (12) and the turbine impeller (5) has turbine impeller blades (15) which are connected to a main part of the turbine impeller (14). The pump impeller (3) and the turbine impeller (5) are each mounted in a rotatable manner about a central axis (11) and the blades of the pump impeller (13) have boundary edges (19) which are arranged so as to face the boundary edges (19) of the blades of the turbine impeller. At least one of the blades of one impeller (2) has a boundary edge (19) which is divided into a first section (21) with a first edge contour (25) and a second section (23) with a second edge contour (27) the first (25) and second edge contour (27) being different.
