摘要： A bearing protector employing a stator and a rotor defining a labyrinth therebetween and disposed for sealing cooperation between a housing and a rotatable shaft. The concentrically fit within one another due to relative axial movement therebetween, each is constructed as an integral continuous one-piece ring. The stator and rotor are axially secured in an assembled condition by a one-piece snap ring carried by the stator and which resiliently distorts to pass axially over the rotor and then resiliently snaps inwardly into a groove in the rotor so as to become fixed to and rotate with the rotor. This snap ring projects outwardly into a radially enlarged annular collecting chamber formed in the stator and acts, when the rotor rotates, as a slinger ring so that contaminates which enter into the labyrinth from the outside come into contact with the slinger ring and are thrown outwardly to the bottom of the collecting chamber for discharge through a drain.
摘要翻译：一种轴承保护器，其使用定子和转子，在其间限定迷宫，并设置成用于密封壳体和可旋转轴之间的配合。由于它们之间的相对轴向运动，它们彼此同心地配合，每个构造为整体连续的单件环。定子和转子在组装状态下通过由定子承载的一体式卡环轴向固定，并且其弹性扭曲以轴向方向穿过转子，然后弹性地向内压入转子中的凹槽中，以便固定到与转子一起旋转。该卡环向外突出到形成在定子中的径向扩大的环形收集室中，当转子旋转时，其作为抛油环，使得从外部进入迷宫的污染物与抛油环接触并向外抛出到收集室的底部，以通过排水口排放。

摘要： An improved laminar flow elbow system and method wherein the elbow system comprises a straight pre-pipe section to define the flow path of a fluid; the pipe section included directly prior to the inlet of a curved pipe section and having and comprising a plurality of vanes to impart a rotation to the fluid before passing through a curved pipe section to provide a generally flat velocity profile at the exit of the curved pipe section and to minimize turbulence of the fluid as it passes through the curved pipe section, and a substantially straight post-pipe section to define a flow path exit pipe section included directly at the exit of the curved pipe section, and containing a plurality of vanes to impart a backward rotation movement to the fluid flow from the exit of the curved pipe section, to substantially terminate rotation of the fluid upon exiting from the straight pipe section without substantial deterioration of the flatness of the fluid velocity profile and without generating substantial amounts of turbulence.
