HYDRODYNAMIC GEARBOX, GEARBOX AND USE

A hydrodynamic bearing for accommodating and supporting a rotating element includes an unloaded sliding surface, a loaded sliding surface downstream of the unloaded sliding surface, a first injection pocket arranged within the unloaded sliding surface and a second injection pocket arranged within the loaded sliding surface. A radial recess arranged within the unloaded sliding surface and the loaded sliding surface extends in a circumferential direction such as to overlap the first and second injection pockets in the circumferential direction upstream and downstream. The radial recess defines or delimits an active area of the unloaded and loaded sliding surfaces. Each of the first and second injection pockets has an axial length which is smaller than an axial extension of the active area upstream or downstream in a corresponding circumferential sliding section of the unloaded sliding surface and loaded sliding surface in which the first and second injection pockets respectively are arranged.
