补充资料:磁流体轴承
用导电流体作润滑剂并有外加磁场的滑动轴承。磁流体轴承是 20世纪 60年代配合核动力设备而发展起来的新型轴承。常用的导电流体有:高温下多用熔融的钠、钾和钠钾共晶合金;在常温环境中则用水银。磁流体轴承与液体润滑的滑动轴承一样,可做成液体动压轴承和液体静压轴承,按结构型式分为圆柱径向轴承、平面推力轴承、球形轴承和锥形轴承等。图1为磁流体动压径向轴承,图2为磁流体静压推力轴承。磁场由永磁体或电磁线圈产生,磁场方向垂直于导电流体的流动方向。流体中的感生电流与磁场相互作用产生洛仑兹力,其大小与流体的导电率、速度和磁感应强度平方成正比,其方向与流体的流动方向相反,对流体的运动起阻滞作用,使流体的等效粘度成倍增加,从而大大地提高轴承的承载能力。
