    • The invention relates to a hydrodynamic bearing, particularly for a spindle motor, comprising a shaft, a thrust plate connected to the shaft and a bearing sleeve closed at one end by a cover plate, the bearing sleeve enclosing the shaft and the thrust plate with a slight radial spacing forming a concentric bearing gap filled with a lubricant. As is already known, the surfaces of the bearing sleeve and the shaft facing each other form at least one radial bearing region and the surfaces of the bearing sleeve, the cover plate and the thrust plate facing each other form at least one axial bearing region. In the hydrodynamic bearing according to the invention, at least one connecting channel is provided which connects a section between the bearing sleeve and the shaft abutting the radial bearing region and a section of the bearing gap abutting the axial bearing region to each other.
    • 本发明涉及一种特别用于主轴电动机的流体动力轴承,包括轴,连接到轴的止推板和在一端由盖板封闭的轴承套筒,轴承套筒将轴和推力板封闭在一起 轻微的径向间隔形成填充有润滑剂的同心轴承间隙。 如已经知道的那样,轴承套和轴彼此相对的表面形成至少一个径向支承区域,并且轴承套筒,盖板和止推板彼此面对的表面形成至少一个轴向支承区域。 在根据本发明的流体动力轴承中,提供了至少一个连接通道,其连接轴承套筒和抵靠径向支承区域的轴线之间的部分以及轴承间隙的与轴向支承区域彼此邻接的部分。

    • A lubricating device for supplying a plurality of lubricating points or positions, in particular of a knitting machine, with lubricant, preferably oil, has a lubricant distributor (16) which is connected on the inlet side to the pressure side of a piston-type lubricant pump (9-13) and which has lubricant outlets (26, 29) which are associated with the individual lubricating points and can be individually activated by the lubricant distributor. For this purpose, the lubricant distributor contains a distributor element (21, 21') which is rotated by a controlled motor (40) and is provided with a distributor channel via which a flow connection is established between the pressure side of the piston pump and the respectively selected lubricating point or position, in a program-controlled manner. The time duration of lubricant flow to the lubricating points or positions can be controlled, so that each lubricating point or position receives the required lubricant.
    • 用于向润滑剂(优选为油)供给多个润滑点或位置,特别是针织机的润滑装置具有润滑剂分配器(16),其在入口侧连接到活塞式润滑剂的压力侧 泵(9-13),并且具有与各个润滑点相关联的润滑剂出口(26,29),并且可以由润滑剂分配器单独启动。 为此,润滑剂分配器包含由受控电机(40)旋转的分配器元件(21,21'),并且设置有分配器通道,通过该分配器通道在活塞泵的压力侧和 分别选择的润滑点或位置,以程序控制的方式。 可以控制润滑剂流向润滑点或位置的持续时间,以便每个润滑点或位置接收所需的润滑剂。
