摘要： A plain bearing assembly of a rotational element on a bearing bolt includes a bearing bolt, a bearing sleeve, which is non-rotatably mounted on said bolt and which comprises a first radial bearing surface formed on its outer periphery, and a rotational element which is rotatably mounted on the bearing sleeve and which is mounted on the first radial bearing surface via a second radial bearing surface in such a way that it can slide. Axial bearing washers, which project radially beyond the bearing sleeve, are secured to both end faces of the rotational elements. The washers run against axial bearing surfaces of the bearing sleeve, and axial flanks of the bearing sleeve form axial bearing surfaces for the axial bearing washers.

摘要： The present invention relates to hydrodynamic bearings, X-ray tubes, X-ray systems, and a method of manufacturing a hydrodynamic bearing for an X-ray tube. The rotor of a hydrodynamic bearing is supported, in steady-state operation, by the pressure of lubricant which is pumped through grooves in the rotor. When the rotor is speeding up or slowing down, the pumping force will not be sufficient to lift the rotor clear of a stationary bushing, and damage, caused by direct contact of the metal surfaces of the bearing, can occur. Providing special coatings on the bearing surfaces can ameliorate this effect.

摘要： There is provided a resin composition for a machinable liner of a sliding member. An ultraviolet curable resin composition for a self-lubricating liner contains a (meth)acrylate compound having an isocyanuric acid ring represented by the following formula and PTFE as a solid lubricant. In the formula (1), X is a group which contains an acryloyl group and is composed only of C, H, and O. Y and Z are groups each composed only of C, H, and O. PTFE is contained in an amount of 10 to 50% by weight with respect to a total amount of the ultraviolet curable resin composition. The ultraviolet curable resin composition is suitable for a self-lubricating liner 24 of a spherical bearing 20 having an outer race 22 and an inner race 26.
