摘要： An X-ray tube of a rotating anode type for reducing acoustic noise and vibration by using an isolating structure which suppresses and prevents transmission of the vibrational energy from the rotating anode assembly to a vacuum envelope and a housing of the X-ray tube. The isolating structure comprises at least one flexible member which is connected between a support structure of the the anode assembly and a neck portion of the vacuum envelope forming a hermetical sealing therewith, and symmetrically disposed isolating members placed between the neck and head portions of the vacuum envelope and the housing, respectively. The flexible members of the isolating structure can be incorporated into the walls of the vacuum envelope.

摘要： A rotary anode type X-ray tube comprises a thin gas passageway extending from a lubricant chamber formed along the axis of a stationary structure and open at a fine gap G effective for preventing a lubricant leakage. In manufacturing the tube, a liquid metal lubricant is supplied to the lubricant chamber and to a slide bearing section, followed by assembling the tube and, then, sealing the assembled tube in a vacuum vessel. In the subsequent exhausting step, an open end of the gas passageway is allowed to face upward. The particular exhausting operation permits completely releasing to the outside the gas impregnated in the bearing-constituting members and the liquid metal lubricant, making it possible to maintain a stable bearing function.

摘要： X-ray tube noise is reduced by coupling the stator mass to the neck section of the glass vacuum tube so that vibrations are dissipated by the stator and not transmitted to the bulk of the vacuum tube. The coupling is accomplished with a non-magnetic sealing material such as an epoxy sealant. The sealant will generally fill the gap between the stator and the neck section of the vacuum tube. Alternatively, the coupling can be done with a mechanical clamping device.

摘要： An x-ray tube rotor structure wherein a target support stem has an externally threaded end portion engaged with an internally threaded surface of an encircling bushing and fixedly attached thereto by an interposed brazed joint. The stem is made of predominantly molybdenum material having a linear thermal expansion coefficient of 58.times.10.sup.-7 per degree Fahrenheit and is thermally matched with the bushing which is made of an iron cobalt nickel alloy material having a linear thermal expansion coefficient of 60.times.10.sup.-7 per degree Fahrenheit. The bushing has an outer surface fixedly attached through a welded joint with an inner surface of an annular plug which has an outer marginal portion fixedly attached to an adjacent end portion of a coaxial rotor skirt. The annular plug is made of an iron chrome nickel alloy material having a linear thermal expansion coefficient of 84.times.10.sup.-7 per degree Fahrenheit and is thermally compatible with the rotor skirt which is made of magnetic flux conductive steel having a linear thermal expansion coefficient of 75.times.10.sup.-7 per degree Fahrenheit. Thus, the largest thermal disparity and the maximum thermal stresses occur between the bushing and the plug at the interposed welded joint which is structurally stronger than the brazed joint between the bushing and the stem.

摘要： An x-ray rotor structure wherein a target support stem has an externally threaded end portion brazed to an internally threaded surface of an encircling bushing which is provided with a barrier layer of oxidation restricting material. The stem is made of predominantly molybdenum material and the bushing is made of iron cobalt nickel alloy material having therein a small percentage by weight of titanium. The barrier layer comprises a layer of substantially pure nickel material which coats the entire inner surface of the bushing including the internally threaded portion thereof. Thus, the titanium is restricted from leaching to the surface during brazing and forming oxides which prevent the surface from being completely wetted by the brazing material. As a result, during brazing, the liquified brazing material alloys with the nickel material of the barrier layer to wet the inner surface of the bushing completely. Consequently, upon cooling, the alloyed brazing material and the nickel material of the barrier layer constitute an interlocking layer forming a durable brazed joint for fixedly attaching the bushing to the stem.

摘要： The rotor that carries the target in a rotating anode x-ray tube is carried on a shaft that is journaled in axially spaced apart ball bearings. The outer and inner races of the bearings have curved grooves presented toward each other and there are a plurality of balls in the grooves. A preloaded spring is interposed between corresponding races of the bearings for applying oppositely directed axial forces to them. The grooves are so shaped and the clearance between the balls and groove surfaces is such that when the axial force is applied, one race shifts axially relative to the other in which case each ball has two points of contact, one point at which the ball contacts the surface of the groove in the outer race on one side of a plane transverse to the shaft axis and another point where the ball contacts the surface of the groove in the inner race on the other side of the plane. The chosen axial preload force is in a range of forces that compels many balls to share the radial load of the rotor and target to minimize contact stress on each ball and the races and the preload spring force range begins just above the force that would result in one or a few of the balls carrying the radial load.
