    • A vertically mountable shaft and bearing assembly includes a thermally insulated housing which protects the shaft, bearing(s), seal(s), and bearing lubricant from overheating due to a surrounding process fluid at a temperature exceeding 65° C. The thermal insulation, which in some embodiments includes vacuum, air, or an insulating material, enables a rolling element bearing to be located near the shaft's distal end, thereby reducing shaft and bearing size requirements. Lubricant is circulated past the bearing(s) by a circulation and cooling system having a capacity typical of systems used with process fluids at much lower temperatures. Additional roller and/or journal bearings can be included. The lubricant circulation system can be actuated by the shaft or driven separately. Lubricant within the shaft housing can be pressurized, for example by pressurizing gas or by filling the lubricant above the surrounding process fluid level. The shaft can operate a process fluid pump impeller.
    • 垂直安装的轴和轴承组件包括一个隔热的外壳,其保护轴,轴承,密封件和轴承润滑剂免受过温度超过65℃的周围​​过程流体的过热。隔热, 其在一些实施例中包括真空,空气或绝缘材料,使得滚动元件轴承能够位于轴的远端附近,从而减少轴和轴承尺寸要求。 润滑剂通过循环和冷却系统循环通过轴承,该循环和冷却系统具有在较低温度下与过程流体一起使用的典型系统的能力。 可以包括额外的滚子和/或轴颈轴承。 润滑剂循环系统可以由轴致动或单独驱动。 轴壳体内的润滑剂可以被加压,例如通过对气体进行加压或者通过将润滑剂填充到周围的过程流体水平以上。 轴可以操作过程流体泵叶轮。

    • The invention relates to a ball joint, especially a wheel guidance joint for motor vehicles. Said ball joint comprises a housing (1) with a cavity (2) that is open to at least one side. A bearing shell (3) that accommodates a ball (4) is inserted in said cavity. The bearing shell (3) can be displaced, together with the ball (4) that it receives, in the cavity (2) along an axis (6). A first shoulder (7) and a second shoulder (8) define end stops in the cavity (2) of the housing (1), a limited free trajectory (5) of the displaceable bearing shell (3) being defined between said two stops. The inventive joint is further characterized in that the bearing shell (3) is mounted in the cavity (2) under the effect of a gentle radial pretension. At least one compensating element (15) is arranged between the outer surface of the bearing shell (3) and the inner surface of the cavity (2).
    • 本发明涉及一种球接头,尤其涉及用于机动车辆的车轮导向接头。 所述球形接头包括具有至少一侧开口的空腔(2)的壳体(1)。 容纳球(4)的轴承壳(3)插入所述空腔中。 轴承壳(3)可以与其接收的球(4)一起沿着轴线(6)位移到空腔(2)中。 第一肩部(7)和第二肩部(8)限定在所述壳体(1)的空腔(2)中的端部止动件,所述可移动轴承壳体(3)的有限的自由轨迹(5)被限定在所述两个止挡 。 本发明的关节的特征还在于,在温和的径向预张力的作用下,轴承壳(3)安装在空腔(2)中。 至少一个补偿元件(15)布置在轴承壳体(3)的外表面和空腔(2)的内表面之间。
