摘要： The invention relates to plain thrust bearings, wherein one working surface of which is made of siliconized graphite (or other antifriction material with similar characteristics) and can be used in assemblies of electrical machines and hydraulic machines having thrust bearings of a large size (with a diameter up to 900 mm), preferably electric motors driving a main circulation pump assembly (MCPA) of reactor assemblies, for example, in nuclear power plants. The plain thrust bearing comprises interleaving bearing bands and slots on the side facing to a set of sector. The bearing disk is provided with mounting surfaces, wherein external and internal rings securing the sectors made of antifriction material through elastic elements are mounted on the mounting surfaces. The sectors are fixed to deter them from rotation relative the bearing ring by intermediate bars arranged between the sectors, wherein the bars are fixed by inserting their pins into the openings in the bearing disk. The sectors made of antifriction material are provided with steps for the external and internal rings, wherein upper parts of the sectors are provided with roundings and lower parts of the sectors are provided with slots for mutual axial fixation. A sector's lead-in edge is shaped approximately as a parabolic curve. Cooling and lubricating is carried out through interleaving channels formed by the bars, the sectors, the external and the internal rings.
摘要翻译： 本发明涉及平推力轴承，其中一个工作表面由硅化石墨（或具有相似特性的其它抗摩擦材料）制成并且可用于具有大尺寸止推轴承的电机和液压机的组件中（具有 直径高达900mm），优选电动机驱动例如核电站中的反应器组件的主循环泵组件（MCPA）。 滑动推力轴承在面向一组扇形的一侧包括交错的轴承带和槽。 轴承盘设置有安装表面，其中通过弹性元件将由抗摩擦材料制成的扇区固定的外部和内部环安装在安装表面上。 通过设置在扇区之间的中间杆将这些扇区固定以防止它们相对于轴承环旋转，其中通过将它们的销插入轴承盘的开口中来固定这些杆。 由减摩材料制成的扇段具有用于外环和内环的台阶，其中扇段的上部设有圆角，扇段的下部设有用于相互轴向固定的槽。 一个扇区的导入边缘大致成形为抛物线曲线。 冷却和润滑通过由杆，扇区，外部和内部环形成的交错通道进行。
