摘要： A bearing isolator seal having a shut off O-ring is tolerant of axial rotor-stator misalignment and provides an enhanced static seal while minimizing rotational wear. A tapered section of the stator is overlapped by the shut off O-ring. When the rotor is static there is no axial misalignment, and the shut off O-ring is pressed against the tapered section, forming an enhanced seal. During rotor rotation, increased axial misalignment moves the O-ring away from the tapered section, reducing rotational wear. The stator can extend horizontally beyond the tapered section and below the O-ring, so that if the rotor moves beyond a maximum misalignment, there is a “line on line” fit between the stator and rotor. The bearing isolator seal can include labyrinth technology, and the tapered section can include a contour that allows the shutoff O-ring to drag along the surface of the tapered section with no hang-ups or binding.
摘要翻译：具有关闭的O形圈的轴承隔离器密封件能够承受轴向的转子 - 定子未对准并提供增强的静态密封，同时最小化旋转磨损。定子的锥形部分与关闭的O形圈重叠。当转子处于静止状态时，不会出现轴向不对中现象，并且关闭的O形圈会压在锥形部分上，形成更好的密封。在转子旋转过程中，增加的轴向不对中将使O形圈远离锥形部分，从而减少旋转磨损。定子可以水平延伸超过锥形部分并在O形圈下方，这样，如果转子移动超过最大不对中，定子与转子之间就会有一个“在线连线”。轴承隔离器密封可以包括迷宫技术，并且锥形部分可以包括允许关闭的O形环沿着锥形部分的表面拖曳的轮廓，而无需挂起或装订。

摘要： A bearing isolator seal provides enhanced coupling and stability of the rotor to the shaft, without undue seal enlargement, by including a plurality of drive O-rings in a common retention groove. In embodiments, the isolator seal accommodates axial rotor misalignment up to a maximum permitted axial misalignment, which can be at least 0.025″. Embodiments include a labyrinth passage between the rotor and the stator configured to expel fluid by centrifugal force. Embodiments include a shut off feature that takes advantage of axial misalignment. Some embodiments include a unitization feature that holds the rotor and stator together during assembly. The unitization feature can include chamfers on rotor and stator extensions that facilitate assembly and disassembly when sufficient force is applied.
