摘要： The current diverter rings (CDRs), captured CDRs, bearing isolators, and explosion-proof CDRs serve to dissipate an electrical charge from a rotating piece of equipment to ground, such as from a motor shaft to a motor housing. One embodiment of the explosion-proof CDR includes a stator that may be mounted to the equipment housing and a rotor that may be mounted to a shaft. The rotor may rotate with the shaft may be encompassed by stator and a cap, which cap may be secured directly to the stator or the housing. A conductive assembly may be positioned in a radial channel formed in the stator such that the conductive assembly contacts the shaft to conduct electricity from the shaft to the housing. Another embodiment of an explosion-proof CDR does not require a rotor. The explosion-proof CDR may be configured to define a flame path to achieve various explosion-proof certifications.

摘要： This invention relates to a restrictive seal of the labyrinth type of reduced external size. The invention has an inner deflector which is capable of retaining the lubricating oil within the bearing housing with great efficiency, and a highly accurate system for adjusting and aligning the elements of the labyrinths, ensuring an infinite service life. Because it has very much smaller external dimensions it can be applied as a replacement to the lip seals commonly in use without causing problems to accessory equipment connected to a pump.

摘要： An improved cartridge-type bearing seal includes removably connected stator and rotor sections. The stator section supports a distribution ring that divides an internal annular volume into radially outside and inside portions. The ring has a sufficient number of tangentially oriented ducts to permit fluid communication between the outside and inside portions. With this structure, when pressurized purge fluid is supplied to the outside portion, the fluid flows through the ducts, to induce a desired tangential fluid flow within the inside portion. This in turn causes circumferentially uniform fluid pressure in the annular volume that resides between the rotating shaft and the bearing housing, and the pressurized fluid traverses a flow path out of the bearing. This circumferentially uniform fluid pressure, by itself or in combination with a flexible lip, prevents contaminant ingress between the rotating shaft and the bearing housing. Because the structure that creates the tangential fluid flow is part of the removable cartridge, this bearing seal eliminates the need to machine or drill a tangentially oriented passage in the bearing housing. One embodiment adds a secondary ring adjacent the distribution ring, to reduce the need to precision machine the inside dimension of the bearing cap. These structural components render the circumferential purge fluid feature even more readily available, for a wider range of spindles.

摘要翻译： 改进的盒式轴承密封件包括可拆卸地连接的定子和转子部分。 定子部分支撑分配环，该分配环将内部环形容积分成径向的外部和内部。 环具有足够数量的切向导向的管道，以允许外部和内部之间的流体连通。 利用这种结构，当将加压清洗流体供应到外部时，流体流过管道，以在内部部分内引起期望的切向流体流动。 这又导致驻留在旋转轴和轴承壳体之间的环形体积中的周向均匀的流体压力，并且加压流体将流动通道流出轴承。 这种周向均匀的流体压力本身或与柔性唇缘组合防止了旋转轴和轴承壳体之间的污染物进入。 因为产生切向流体流动的结构是可移除筒的一部分，所以该轴承密封件消除了在轴承壳体中加工或钻取切向定向通道的需要。 一个实施例在分配环附近添加了次级环，以减少对精密加工轴承盖的内部尺寸的需要。 对于较宽范围的主轴，这些结构部件使圆周清洗流体特性更容易获得。

摘要： An isolator seal includes a stator member for placement into the stator of rotating equipment and a rotor member for placement onto a rotary shaft of the rotating equipment. The stator member and the rotor member provide respective adjacent surfaces, while a static shut-off device engages both adjacent surfaces when the rotor member is static and disengages one or more of the surfaces when the rotor member is dynamic. In one embodiment of the invention at least one of the surfaces is inclined to the longitudinal axis at an angle greater or less than 90°. In a further embodiment, the static shut-off device includes a resilient annular sealing member and an auxiliary member, which can move between a first position, when the rotor member is static, at which the auxiliary member compresses the resilient annular member into engagement with both surfaces, and a second position at which the compression on the resilient member is reduced, so that the resilient annular member disengages one or more of the rotor and stator surfaces when the rotor is dynamic.

摘要： An isolator device, which may be a bearing seal or a bearing isolator, for use hindering fluid flow between components which are rotating relative to each other about a longitudinal axis, the flow being in one direction parallel to this axis, includes a stator for securing to a rotary fixed one of the components and a rotor for securing to a relatively rotating one of the components. The stator has a surface which extends longitudinally and adjacent to a surface of a component, which rotates relative to the stator. The fluid flow is between the two surfaces and the stator surface is non-parallel to the adjacent component surface and is shaped to promote fluid flow in a direction opposing the general fluid flow direction.

摘要： A unitized seal assembly for use with roller or ball bearing assemblies is disclosed. The unitized seal assembly includes, among other things, a radially outer ring and a radially inner deflector ring. The outer ring includes a first shield element which defines a first sealing face. The radially inner deflector ring includes a second shield element which defines a second sealing face. The second sealing face is dimensioned and configured so as to correspond to the first sealing face such that when the first shield element is positioned in non-contacting proximity to the second shield element, a circuitous sealing labyrinth is formed between the first sealing face and the second sealing face.

摘要： An assembled idler roll having an outer shell and end bearing assemblies. The bearing assemblies each have an outer race and an inner race. The inner race is press fitted onto a roller shaft to an initial position which is spaced inwardly from a final desired position. The outer shell of the roll is restrained and the shaft is reciprocated along its longitudinal axis to determine the degree of axial movement. The inner race of the bearing assembly is moved from its initial position to its final position as determined by the degree of axial movement.
