摘要： A coolant passage is formed inside the rotary shaft while an air passage is formed inside the casing. A mechanical seal is arranged between the coolant passage and the air passage. Leakage cooling water, which has leaked in the form of vapor from the mechanical seal, is relegated radially outwardly along with air by the action of a rotary vane, which is disposed in the air passage, and finally flows out of an air outlet. A coolant sensor may be provided to early detect the leakage water.

摘要： An anode target is roratably supported by a rotating mechanism having a rotary body and a staionary body. A fitted portion between the rotary body and the stationary body is formed of bearing areas having dynamic pressure type sliding bearings and a non-bearing area having a clearance between the rotary body and the stationary body larger than that in the bearing areas. The rotary body facing the non-bearing area is positioned where a time for heat transfer from the anode target is shorter than the rotary body facing the bearing areas. Thus, the characteristics of heat radiation from the anode target can be improved, and a stable bearing operation can be maintained.

摘要： A valve is provided to fill a chamber for holding a rotation shaft of a rotating anode in an X-ray tube. The valve has a needle supported on a seat. The needle maintains the vacuum in the tube. A sleeve can engage in the valve. The sleeve is hollow and has a cavity. This cavity can be connected to the vacuum or to a bottle under vacuum filled with a lubricant liquid. The sleeve is used to handle the needle. The sleeve furthermore bears on a rim of the valve by an O-ring joint. This joint maintains the vacuum when the needle is raised and when the tube under vacuum is connected to the cavity of the sleeve.

摘要： A rotary bulb tube of an x-ray radiator is mounted for rotation in a housing, which is filled with a coolant and is connected to a shaft section, which in turn is connected by a coupling to a second shaft section extending to a motor for rotating the bulb tube. The coupling is designed to isolate the rotary bulb tube electrically from the motor and to isolate the bulb tube from motor vibrations.

摘要： The invention relates to a method of connecting workpieces which is suitable notably for connecting an anode rod (5) to an end plate (6) of a rotor sleeve (7) in a rotary anode X-ray tube where on the one hand adequate strength is required and on the other hand an as small as possible cross-section of the anode rod so as to realize a heat barrier. The method is characterized mainly in that the objects are connected to one another by friction welding and that the cross-section is reduced, that is, outside a connecting zone in which the friction weld is situated, in such a manner that the strength of the connecting zone is at least slightly greater than that of the segment of reduced cross-section.
