Claim 0:
1. A hydrodynamic slide bearing (10, 10′) for supporting a shaft (14, 14′) that is rotatable in a rotation direction about an axis, the slide bearing (10, 10′) comprising:
a plurality of bearing segments (12, 12′) arranged next to one another in the rotation direction (22, 22′), wherein the bearing segments (12, 12′) have segment surfaces that together form a running surface (16, 16′) for facing a surface of the shaft (14, 14′) the segment surface of at least one of the bearing segments (12, 12′) having a plurality of grooves (26, 26′) oriented substantially transverse to the rotation direction (22, 22′), wherein:
each of the grooves (26, 26′) has a front groove edge (262) and a rear groove edge (261) disposed relative to one another so that a point moving along the respective segment surface in the rotation direction first passes an intersection of the segment surface with the front groove edge (262) and then passes an intersection of the segment surface with the rear groove edges (261),
the rear groove edge (261) of each of the grooves (26, 26′) is orientated obliquely to a rear radial plane (24, 24′) that passes through both the axis and the rear groove edge (261), and each of the rear groove edges (261) is undercut in relation to the rear radial plane (24, 24′), and
the front groove edges (262) of each of the grooves (26, 26′) is oriented obliquely to a front radial plane (24, 24′) that passes through both the axis and the front groove edge (262) and, each of the front groove edges (262) is not undercut in relation to the front radial plane (24, 24′).
