Abstract:
1. Hydrodynamic bearing having a shaft ( 4 ), a thrust plate ( 13 ) connected to the shaft and a bearing sleeve ( 3 ) closed at one end by a cover plate ( 14 ; 314 ) and sealed at the other end by a capillary seal, the bearing sleeve ( 3 ) enclosing the shaft and the thrust plate with a slight radial spacing forming a concentric bearing gap ( 8 ) filled with a lubricant, the surfaces of the bearing sleeve ( 3 ) and the shaft ( 4 ) facing each other forming at least one radial bearing region ( 9 ; 10 ) and the surfaces of the bearing sleeve ( 3 ), the cover plate ( 14 ; 314 ) and the thrust plate ( 13 ) facing each other forming at least one axial bearing region ( 2 ), characterized by at least one connecting channel ( 17 ; 117 ; 217 ; 317 ) that connects a section between the bearing sleeve ( 3 ) and the shaft ( 4 ) abutting the radial bearing region ( 9 ) and a section of the bearing gap ( 8 ) abutting the axial bearing region ( 20 ) to each other without directly connecting to the capillary seal.
