    • A fluid-powered high-speed spindle (100) having a longitudinal axis (A) defining an upper end defined by a shank and a lower end accepting a tool. The spindle includes a body (120), a rotatable shaft (530) supported by at least one bearing (508) within the body (120), a seal housing (150) connected to the body (120) at the lower end thereof, a cover (180) connected to the seal housing (150) at the lower end thereof, a fluid channel system for directing fluid from an entry port (102) to a nozzle (576) for turning a turbine (570) attached to the shaft (530); and a flinger (660) attached to the shaft (530) and positioned above the turbine (570). The flinger (660) and the seal housing (150) combine to form a non-contact seal (900) configured to impede the flow of fluid toward the at least one bearing (508).
    • 流体动力的高速主轴(100)具有纵向轴线(A),该纵向轴线限定由柄限定的上端,并且下端接受工具。 主轴包括主体(120),由主体(120)内的至少一个轴承(508)支撑的可旋转轴(530),在其下端连接到主体(120)的密封壳体(150) 在下端连接到密封壳体(150)的盖(180),用于将流体从入口(102)引导到喷嘴(576)的流体通道系统,用于转动附接到轴的涡轮机(570) (530); 以及附接到所述轴(530)并且定位在所述涡轮机(570)上方的挡泥板(660)。 悬挂器(660)和密封壳体(150)组合以形成非接触式密封件(900),其构造成阻止流体朝着至少一个轴承(508)流动。
