The invention relates to a bearing segment (1) for a strained hydrodynamic axial plain bearing, especially for an electric machine such as a hydro generator, comprising two subassemblies that are movable relative to each other. One subassembly performs a rotary movement while the other subassembly is equipped with at least one such bearing segment (1) that is connected to a rigid base, a lubricant gap being formed between opposite sliding surfaces of the two subassemblies in the operating state. In order to improve said axial plain bearing, the bearing segment (1) is provided with at least one compensation duct (8) for the lubricant, which interconnects a relative high-pressure zone within the lubricant gap and a relative low-pressure zone within the lubricant gap.
L'invention concerne un segment de palier (1) destiné à un palier à glissement axial hydrodynamique résistant à des contraintes élevées, notamment un moteur électrique tel qu'un hydrogénérateur, comportant deux modules pouvant être réglés l'un par rapport à l'autre, un des modules décrivant un mouvement rotatif et l'autre module comportant au moins un tel segment de palier (1) connecté à une base solide. En fonctionnement, un espace de lubrifiant se forme entre des surfaces de glissement opposées des deux modules. Pour améliorer le palier à glissement axial, le segment de palier (1) présente au moins un canal de compensation (8) destiné au lubrifiant, connectant une zone de pression relativement élevée dans l'espace de lubrifiant à une zone de pression relativement faible dans l'espace de lubrifiant.
