摘要： A seal and bearing assembly of a gas turbine engine having an engine case with a cooling fluid nozzle located between a bearing outer ring and ring segments, and a rotary shaft for rotation in the engine case around a main axis, the seal and bearing assembly can be assembled by positioning the engine case and the rotary shaft in axial alignment, and axially moving the engine case relative to the rotary shaft including moving the bearing outer ring across the axial location of the runner portion and into an assembled condition. The rotary shaft having mounted thereon a bearing inner ring and a runner assembly having a runner portion, a sleeve portion being concentric and radially internal to the runner portion, and a cooling fluid passage having a radial segment leading from an outgoing segment to a returning segment extending in a direction leading back toward the bearing inner ring.

摘要： A fluid cooled seal arrangement for a gas turbine engine including a first sealing element coupled to a mechanical housing of the engine, and a second sealing element connected to a shaft rotatable within the housing. The first and second sealing elements are arranged radially adjacent to one another to form a rubbing interface therebetween. A lubrication system for delivering cooling fluid to the second sealing element through a passageway arranged along the rotating shaft. The cooling fluid is discharged through a plurality of openings formed in one end of the passageway. During normal operation of the engine the centrifugal force from the rotation of the shaft flings the oil radially outward to a channel formed on the underside of the second sealing element. The channel receives the cooling fluid therein, and allows for the escape of the cooling fluid onto the underside of the second sealing element to provide a uniform thickness of cooling fluid thereon. A uniform film of cooling fluid will result in the more uniform transfer of heat from the second sealing element.
摘要翻译：一种用于燃气涡轮发动机的流体冷却密封装置，包括联接到发动机的机械壳体的第一密封元件和连接到在壳体内可转动的轴的第二密封元件。第一和第二密封元件彼此径向相邻设置，以在它们之间形成摩擦界面。一种用于通过沿着旋转轴布置的通道将冷却流体输送到第二密封元件的润滑系统。冷却流体通过形成在通道一端的多个开口排出。在发动机的正常操作期间，来自轴的旋转的离心力将油径向向外旋转到形成在第二密封元件的下侧上的通道。通道在其中接收冷却流体，并且允许冷却流体逸出到第二密封元件的下侧，以在其上提供均匀的冷却流体厚度。冷却流体的均匀膜将导致来自第二密封元件的更均匀的热传递。

摘要： A vertical heat treating apparatus includes a cap body, which is movable up and down, for sealing a treatment vessel that holds objects to be treated. A rotary loading device is provided with a rotary shaft which extends into a through hole provided in the cap body, and a magnetic fluid seal member is provided around the rotary shaft. Heat-exchange media, such as water or ethylene glycol, is circulated within the rotary shaft, preferably to cool the rotary shaft. A temperature sensor may be provided in a housing for the rotary shaft, such that when the temperature exceeds a set temperature, the flow rate of the heat exchange medium is increased. Baffle plates may be provided above an upper surface of the cap body and opposed to the through-hole in the cap body. In one preferred embodiment of the invention, nitrogen gas is circulated through the through-hole in the cap body to prevent corrosive gas from contacting the shaft. Circumferential grooves are defined around the rotary shaft at locations where the heat exchange medium is admitted and discharged from the rotary shaft. Preferably, the heat exchange medium is circulated in the rotary shaft above and below the level of the magnetic seal.

摘要： A space (32) is formed between an inner end of a fitting hole (31) formed in a piston (21) and a piston rod (22) and is positioned radially inside a sealing member (24). By circulating a cooling fluid through the space, the majority of heat which is transmitted to the piston rod (22) can be absorbed, preventing transmission of heat to the sealing member. The temperature of the sealing member is kept lower and its deterioration can be inhibited.

摘要： A seal device is adapted to be mounted at an area of relative rotation between two mounting portions of a tire pressure-adjusting device. The seal device includes a pair of first and second seal rings which are disposed in opposed relation to each other. Each of the first and second seal rings includes a main seal of an annular shape having a radially inwardly-directed lip formed on an inner periphery of the main seal, the lip having at its distal end a lip sliding surface to which a self-lubricating thin plate for sliding contact with one of the two mounting portion. Each seal ring further includes an auxiliary seal of an annular shape having a radially inwardly-directed lip which is formed on an inner periphery of the auxiliary seal and is adapted for sliding contact with the one mounting portion, the auxiliary seal being connected to the main seal to form therebetween a closed space for holding grease. A valve is mounted on each of the auxiliary seals for effecting the intake and exhaust of air relative to the closed space.

摘要： A pulverizer roll wheel assembly comprises a bracket with an opening therein for fixing the outer end of a roller shaft. Bearings mount a roller wheel with pulverizing tire to the inner end of the shaft for rotation of the pulverizer. A lip seal assembly separates an oil space around the inner end of the shaft with an air space around the outer end of the shaft. A pop off relief valve normally positioned near the lip seal is repositioned to the outer face of the shaft for easier access. A cover extends over the relocated valve for extending the air space around the relocated valve.

摘要： An oil passage connection between a shaft and a clutch drum is sealed by intentionally providing an imbalance in the forces acting on splines mounting the clutch drum to the shaft. The sides of at least some of the splines are angled, so that at least some part of any torque applied between the clutch drum and shaft is resolved into radial components. By providing a differing number of splines, or an asymmetrical positioning of the splines, the net force can be designed to force the sides of the shaft and the clutch drum adjacent to the oil passage tightly together. This is most easily accomplished by simply omitting one or more splines from the clutch drum on either side of the oil passage. With such a structure, the same splines on the shaft can be used to mount gears and the like, which normally require symmetrical distribution of forces.

摘要： A fluid cylinder has improved wear rings in a combination that includes a tube having a tubular wall and first and second end caps. The tubular wall defines a cylinder bore that has a central axis. Each end cap also has a bore extending along the central axis. A piston assembly is mounted in the cylinder bore with a piston rod mounted in the bore of one of the end caps, so that the piston assembly is slidable along the central axis. The piston assembly includes a piston head that has a reservoir defined by an annular recess opening toward the tubular wall. The reservoir houses a prepacked lubricant. One wear ring closes off the annular recess from the tubular wall. The wear ring seal has a plurality of radial apertures extending therethrough, through which lubricant is capable of flowing to lubricate the piston assembly. Another wear ring closes off a reservoir in the bore of an end cap and functions as the first mentioned wear ring also to lubricate the piston assembly.

摘要： Safety rotary transmissions allow the transfer of fluid media from a stationary casing into the inside of a rotating shaft and back. The apparatus, which has only one face seal, is provided with a blocking device which prevents a contact of metallic parts of the face seal with one another even if there is severe wear of the sliding sealing ring. An exchange of the sealing ring is possible without dismantling the casing.

摘要： An earth boring bit having a rotatable cutter secured to a lubricated, cantilevered bearing shaft, sealed with an improved pressure compensating rigid face seal assembly. The assembly has a rigid ring with a radial face that opposes and engages a radial face integral with a cutter seal groove. A resilient energizer ring is compressed between opposed conical surfaces, one on the rigid ring and the other in a shaft seal groove, to force the radial faces together. The periphery of the energizer ring is inside the journal bearing surface, which is ideally aligned with the mid-section of the ring, to define a essentially constant, lubricant filled, volume between the seal assembly and the shaft seal groove--even as the cutter and seal assembly move relatively to the shaft during drilling. As a result, pressure variations in the vicinity of the seal assembly are minimized.
