    Mounting for a rotary anode in an x-ray tube. A radially outer rotor sleeve, constituting the rotor of an electric motor, has an anode disc connected centrally thereof. A radially inner, supporting sleeve is telescoped within the rotor sleeve and is spaced radially therefrom. A central shaft extending longitudinally of the rotor sleeve and a further sleeve intermediate between the radially inner and outer sleeves has an anti-friction bearing with inner and outer races mounted on its respective ends, the inner race of each bearing being connected to the shaft and the outer race of each bearing being connected to the intermediate sleeve which is disposed coaxially of the rotor sleeve, the intermediate sleeve, and the shaft, and between and spaced from the shaft and the supporting sleeve. The intermediate sleeve is prevented from axial movement with respect to the supporting sleeve. The inner race of the bearing nearer the anode and the end of the shaft at such location are connected to the rotor sleeve by a connecting element. Resilient means are mounted between the respective ends of the intermediate sleeve and the supporting sleeve in alignment with the bearings. In the radially outer anode sleeve there is disposed a centering sleeve the end portion thereof close to the anode disc having the shape of a collet. The connecting element is fixed in the collet with an interference fit, the end face of the collet being spaced from the end portion of the radially outer rotor sleeve which is nearer the anode disc.

    专利说明:

    The invention relates to X-ray technology, namely to X-ray tubes with a rotating anode.
    The known node Vran1, an anode of the anode of the x-ray tube, contains special pipelines, the inner rings of which are located on the shaft connected to the disk of the anode and the outer rings are located in the sleeve forming the anode holder (France Application L 2453498, CLH01J 35/10, 1980). For such a node, it is impossible to ensure, taking into account the high requirements for the anode operating accuracy and especially for the 1-wide range of working temperatures, the necessary working conditions, namely, the attenuation of vibration, and, consequently, the lowering of N1um, the survival of the duster in landing, the life span of the x-ray tube, and the possibility of a significant increase in the frequency of the anode play-up, allowing to increase the power of the x-ray tube.
    The closest technical solution is the vrap1 node of the anode of the x-ray tube, the housing and anode holder with a screw; 1, the shaft with ledges on both its sides, in which the inner rings of the rollers are mounted on the outer side with fixing elements. An end stop is made between the fixing element and the subfiller, located near the anode disk, and the outer rings of the sub-tips are fixed in the anode sleeve of the anode holder (German patent L about 2226714, CL H 01 J 35/10, 1974).
    A disadvantage of the known solution is the high wall of the vibration of the anode, which reduces the durability of the flash books, and hence the X-ray tube as a whole.
    The aim of the invention is to expand the power and durability of the X-ray tube, reducing the shift of the ontic focus of the tube during its operation.
    The goal is achieved by the fact that, in the rotating anode assembly of the Reitgen tube, containing the housing and the anode holder with the on-hub sleeve, the shaft with ledges but both of its sides, in which the rolling elements are embedded, are fixed with all the sides with the help of fixing elements between the fixed element and the bearing located near the anode disk, the face unor is made, and the outer rings 10СЩИ1Ц1ИКОВ are fixed in the support sleeve of the anode holder, the support sleeve is installed in the anode holder with prugih rings disposed in a recess formed in the anode holder and zakren- lena with nomoschyu uirugogo iredohrapptel intended for its nredotvrascheni

    axial non-displacement. In addition, in the bottom of the anode casing there is a centering bushing, part of which is located near the anode disk, made in the form of a collet, in which the end face is fixed with tension, while the collet is separated from () the anode wall of the anode casing, elastic rings contact the bearing sleeve is at least three straight and with the surface of the anode holder also at least three, and these three straight lines do not lie on one n plane, each elastic ring made of metal sheet or foil nrofil
    FIG. 1 is shown in the Preposition. in fig. 2 - the form of the surgeon sleeve.
    On the hollows 1 on both sides of the shaft 2, the bearings 3 are fitted with their inner rings and fixed with fixing elements 5, such as nuts, tightened to prevent rotation. Near the disk 15 of the iodine, the inner ring of subsurface 3 and the fixing element 5 locates the end face 4. The outer rings of the nodal bridges 3 are located in the onboard sleeve 6, which is held in the holder 7 of the anode of the outer ring 8. Supporting sleeve 6 at nominal elastic iredohranitel 9. In the casing 10 of the anode there is a steel centric round sleeve 11, a part of which, located near the anode disk 15, is mounted in the form of a collet 12. is screwed 13 through the collet 12 of the sleeve 11.
    The anode casing 10 together with the steel centering sleeve 11 forms a rotor driven by a stator located outside the vacuum of the x-ray tube. The mechanical load from the anode disk 15 is transmitted through the screws 13 of the front wall 14 of the casing I) of the anode to the end 4 of shaft 2 located on the bushing 3. The collet 12 of sleeve 11 causes the backlash-free concentric position of the casing 10 of the anode relative to the end 4 of shaft 2. Dynamic forces arising from In the vision of unbalanced masses, they are plugged with unrules by rings 8. These rings 8 are made by rolling up a wave-like thin. iHCTOBoro metal or foil. The tenth note from the disc 15 of the anode to the sub-rollers 3 rolls is lowered by the bonding of the end face 4 of the shaft 2 in the collet 12, which is not directly connected to the warm casing 10. The outer rings 8 of the cell isolate the outer rings of the rolling bearings 3, As a result, the Jémeni Jaets have a temperature gradient in nodes 3 of the quality.
