摘要： A bearing and a sealing device. The sealing device includes: a skeleton; and a sealing part, which, taken as a whole, is of an annular structure, the sealing part comprising an elastic part and a plastic part, and the elastic part being fixed to the skeleton. After the sealing device is arranged between a bearing inner ring and a bearing outer ring, the plastic part and the bearing inner ring form contact sealing, the elastic part and the plastic part are relatively fixed, and in the radial direction, at least part of the plastic part is arranged between the bearing inner ring and the elastic part. The coefficient of friction of the material of the plastic part is smaller than the coefficient of friction of the material of the elastic part.

摘要： In order to effect a seal a porous material which comprises one side of two opposing surfaces is used to restrict and evenly distribute externally pressurized gas, liquid, steam, etc. between the two surfaces, exerting a force which is opposite the forces from pressure differences or springs trying to close the two faces together and so may create a non-contact seal that is more stable and reliable than hydrodynamic seals currently in use. A non-contact bearing is also disclosed having opposing surfaces with relative motion and one surface issuing higher than ambient pressure through a porous restriction, wherein the porous restriction is part of a monolithic porous body, or a porous layer, attached to lands containing a labyrinth, the porous restriction and lands configured to not distort more than 10% of a gap created from differential pressure between each side of the porous restriction.

摘要： A track roller assembly includes a wheel body, a bearing, a wheel axle, a cap element, a rotating oil seal, an end cover and an oil body. The wheel body has a thread. The bearing is disposed on the wheel body. The wheel axle is disposed through the bearing. The cap element has a screw corresponding to the thread. One side of the rotating oil seal is connected to the cap element, and another side of the rotating oil seal rotatably abuts the wheel axle. The end cover is connected to the wheel axle. The oil body is limited to an accommodating space formed by the wheel body, the wheel axle, the cap element and the rotating oil seal.

摘要： The invention relates to a shaft bearing having a seal arrangement to prevent steam leakages that can occur in the event of temperature fluctuations or pressure fluctuations between a liquid medium on the one side and a gaseous medium on the other side of the compact bearing, wherein, between a primary radial seal and a rotation bearing portion, a lubrication space surrounding a shaft circumference is arranged that receives a volume of lubricating grease that has a higher viscosity than a lubricating oil and a coolant; and a volume compensator for compensating a temperature-dependent volume fluctuation is provided that comprises a compressible material, and is arranged vertically in interaction with the volume of the lubricating oil and/or the volume of the lubricating grease.

摘要： A bearing assembly for a turbo-engine with a bearing and parts of a bearing temperature detecting device. The bearing includes a main body having a thermoplastic bearing layer. A space is defined in the interior of the main body and of the thermoplastic bearing layer for accommodating parts of the bearing temperature detecting device. The space has a through hole having a first opening in the thermoplastic bearing layer and a second opening located in the main body. The parts include a temperature conducting element, a temperature sensor, and a securing fixture that attaches the temperature conducting element. The first opening of the through hole has a chamfer and the first end of temperature conducting element has a head which is correspondingly shaped to the chamfer in a form fitting manner. The center-axis of the temperature sensor extends transversely to the center-axis of the temperature conducting element.

摘要： The disclosure relates to a bearing arrangement for a bearing end of a fastening shackle in a vehicle body of a vehicle that includes an outer sleeve, an inner sleeve and a sleeve-shaped plastic sliding bearing. The inner sleeve is mounted in the outer sleeve so that the inner sleeve is able to slide. The sleeve-shaped plastic sliding bearing surrounds the inner sleeve and is connected to the inner sleeve in a rotationally fixed manner. The sleeve-shaped plastic sliding bearing is also longer than the outer sleeve and is delimited by a first sleeve rim that protrudes beyond the outer sleeve, where the first sleeve rim is configurable to be form-locked and to resist rotation.
