摘要： A mechanical seal includes a rotation ring provided with a vertical surface which is vertical to a central axis line of the rotation ring. A tapered surface includes a diameter on an outer circumferential side which decreases away from the vertical surface. A plurality of split bodies are positioned by sandwiching an outer circumferential side of the rotation ring between a support member that supports a side of the vertical surface and a presser member that presses the tapered surface. An elastic member is disposed between the support member and the vertical surface, so that the vertical surface is supported through the elastic member. A tapered surface is pressed in direct surface contact with an inner circumferential tapered surface of the presser member.

摘要： A jointless braided sealing ring as well as a method and a special machine for producing such a sealing ring are disclosed. The braided sealing ring adopts a multi-layers braided structure comprising a number of continuously sleeved ring layers arranged from inside to outside. The innermost braided ring layer is used as a core. The tail end of the first braided ring layer (1) is sleeved on the starting end of the first braided ring layer (1) and serves as the starting end of the second braided ring layer (2) to implement continuously braiding without any interruption. The second braided ring layer (2) is sleeved on the first braided ring layer (1) and the third braided ring layer (3) is sleeved on the second braided ring layer (2). The Nth braided ring layer (4) is sleeved on the (N−1)th braided ring layer (5). N braided ring layers have (N−1) continuous intact braided ring layers. The tail end (8) of the outermost braided ring layer is superposed with the starting end (7) of the innermost braided ring layer. Service life and sealing effect of the braided sealing ring are increased. A perimeter-defining ring (6) is provided in the sealing ring to improve the dimensions precision of sealing ring, and avoid that the sealing ring deforms during braiding and trimming.

摘要： A disposable biomedical rotating filtration system for processing fluids in a closed environment includes a rotor mounted for rotation on a pivot pin, a seal between the rotor and pivot pin, an external permanent magnet drive mechanism, and a star shaped drive element mounted on the rotor for rotating the rotor in response to a magnetic field induced by the permanent magnet of the drive mechanism. The drive element on the rotor is stamped from an inexpensive non-permanent ferromagnetic sheet metal and has a configuration and position in relation to the center of said magnetic field such that said drive element receives sufficient torque for driving said rotor and sufficient seal force is applied on the rotor to provide fluid tight seal between the rotating rotor and the seal. The pivot pin is molded from a hard plastic material such as a polyamide base resin having a low coefficient of friction and good lubriciousness. The pivot pin is irradiated by gamma radiation for sterilization and modifying of the plastic material without degradation or loss of lubricious properties.

摘要： A sealing arrangement for a ball-shaped or planar rotary valve of an internal combustion engine comprises a hollow sealing body mounted for rotation in a gas channel of the cylinder head and sealingly engaging the outside sealing surface of the rotary valve. A backside surface of the sealing body turned away from the combustion chamber is permanently exposed to the gas pressure therein in order to urge the sealing body inwards against the rotary valve with a sealing force dependent on the momentary gas pressure.

摘要： A seal ring with tapered surfaces is constituted by an inner ring, outer ring and a tightening resilient member. Each of the inner and outer rings is provided with an inner and outer peripheral surfaces and a pair of sealing end surfaces extending between the inner and outer peripheral surfaces. Each of the inner and outer ring is divided in the circumferential direction into two sections. The inner peripheral surface of the outer ring fits the outer peripheral surface of the inner ring, while the outer peripheral surface of the outer ring is surrounded by the resilient member so that the inner and outer rings are resiliently pressed radially inwardly. The end surfaces of the inner and outer rings are arranged flush to form common sealing surfaces. At least one of the common sealing surfaces thus formed constitutes a conical surface so that the axial distance between two common sealing surfaces is varied such that it increases toward the radially outer side. A sealing device is constituted by the seal ring with tapered surfaces having the above-stated construction, and annular surfaces to be sealed which are provided on two members adapted to rotate relatively to each other so as to oppose to each other, the annular surfaces to be sealed forming therebetween an outwardly diverging gap and being adapted to make close contact with the pair of common sealing surfaces of the seal ring. The radially inward pressing force of the resilient member produces an axial sealing force of the seal ring, through relative sliding contact between the conical sealing surface of the seal ring and the annular surface of the aforementioned member contacting therewith.

摘要翻译： 具有锥形表面的密封环由内圈，外圈和紧固弹性构件构成。 内环和外环中的每一个设置有内外周表面和在内周表面和外周表面之间延伸的一对密封端表面。 内圈和外圈中的每一个在圆周方向上分成两部分。 外环的内周面与内圈的外周面嵌合，而外圈的外周面被弹性部件包围，使得内圈和外圈径向向内弹性地挤压。 内圈和外圈的端面平齐排列以形成公共密封表面。 这样形成的公共密封表面中的至少一个构成锥形表面，使得两个公共密封表面之间的轴向距离变化，使得其朝向径向外侧增加。 密封装置由具有上述结构的具有锥形表面的密封环和被密封的环形表面构成，所述密封环设置在两个构件上，所述两个构件相对于彼此相对地彼此旋转，环形表面 在其间密封形成向外发散的间隙，并且适于与密封环的一对公共密封表面紧密接触。 弹性构件的径向向内的压力通过密封环的锥形密封表面和与其接触的上述构件的环形表面之间的相对滑动接触而产生密封环的轴向密封力。

摘要： A seal device for a rotary heat-exchanger of a gas turbine is held in bearing contact with each end face of a regenerative rotor of the heat-exchanger to partition a low-pressure exhaust gas passage and a high-pressure air passage from one another and to seal therebetween. The regenerative rotor is rotated across the passages to effect the heat-exchanger between the low-pressure exhaust gas and the high-pressure air. The seal device comprises a bellows having one end thereof secured to a seal member rotatably supporting the regenerative rotor and the other end secured to a flange fast on the inner wall of the rotor housing, and a jacket substantially backing up the bellows to control the shape thereof.

摘要： The invention is concerned with novel sealing means for a differential-final drive arrangement and with an assembly method therefore. In a differential-final drive arrangement for a vehicle comprising an axle extending from a differential through a first housing and out a hole therein removed from said differential; a final drive within a second housing having gear means driven by spline means on said axle, said second housing being rotatably supported by said first housing; and a wheel integral with said second housing and rotated by said gear means, the invention provides an improved slidable seal between a first compartment defined by said differential and said first housing and a second compartment defined by said second housing. The improved slidable seal comprises a sleeve thrust bearing about the axle within the second housing having a first end in slidable sealing abutting relation with a respective one of the first housing and the gear means and a second end extending towards a respective other of the first housing and the gear means. The improved slidable seal further includes a sleeve thrust member about the axle within the second housing having a first end abutting a respective other of the first housing and the gear means and a second end fitting within the second end of the bearing. Also a part of the improved slidable seal are compression means biasing the bearing axially away from the member and resilient toroidal sealing means compressed between the axle and the bearing.
