The first seal element surrounds the first shaft and includes a first portion is in contact with the first shaft and a second portion extending in a non-parallel direction to a radial direction of the first shaft. The retaining element is threadably engaged with the first shaft such that the retaining element presses the first seal element against the shoulder of the first shaft.

摘要： A bearing system for a rotor in rotating machines, such as compressors, pumps, turbines, expanders, has points of bearing and sealing for the rotor each being in the form of a combined bearing and sealing formed by a stator situated within a rotating machine house and surrounding the rotor. The stator is formed with a bore, whereby an annular clearance is created between stator and rotor, and the bore is having sectional area gradually increasing in the direction of larger pressure within the rotating machine.

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 method of positioning a shaft and an associated seal in turbomachinery utilizing electromagnetic bearings. The method comprises the steps of applying electrical power to the windings of the electromagnetic bearings in which the shaft center is in a first position and wherein the shaft is in contact with the associated seal. By adjusting the power to the electromagnetic bearings, the seal can be manipulated with the shaft by movement of the shaft in a series of moves of decreasing amplitude to a position in which the seal is out of contact with the shaft when the shaft is rotated at its centered position during normal operation of the turbomachinery. The shaft is in its centered position during normal operation when the shaft axis is substantially coaxial with an axis of the electromagnetic bearings. The series of movements of decreasing amplitude may include oscillations of decreasing amplitude about one or more axes, or may include rotation in a spiral with a radius of decreasing amplitude to move the center of the shaft from an initial position to a final position. Movement of the shaft is accomplished by adjusting the electrical power to the windings of the electromagnetic bearings.

摘要： The invention relates to a magnetic bearing (2) for magnetically suspending a rotating shaft (3) within a stator. Said magnetic bearing comprises a first bearing element (5) rigidly linked with the shaft which is enclosed by a second bearing element (13) pertaining to the stator, thereby defining a bearing clearance (12). A system of magnets (7) of the first bearing element with permanent magnet elements (8i) and a cooled superconducting system (14) of the second bearing element with high Tc superconducting material are commonly enclosed by at least one insulating compartment (V1, V2). An additional compartment (25) which is separate from said insulating compartment encloses the bearing clearance (12) and partial compartments (25a, 25b; 26a, 26b) that radially extend on lateral sides of the superconducting system and of the system of magnets up to the shaft (3) and are sealed from the shaft.
