Abstract

An x-ray emitter housing includes a first housing part and a second housing part that are connected to one another in a form-fit manner using an axially acting threaded ring.

First claim

The invention claimed is:

1. An x-ray emitter housing comprising:
a first housing part;
a second housing part;
a radially sealing element;
an axially acting threaded ring; and
a disk spring;
wherein the first housing part has a larger diameter than the second housing part, and wherein at least a portion of the first housing part overlaps the second housing part along a radial axis of the x-ray emitter housing,
wherein the first housing part and the second housing part are connected to one another in a form-fit manner with the axially acting threaded ring, wherein the axially acting threaded ring is positioned between the portion of the first housing part that overlaps the second housing part,
wherein the second housing part comprises a ring-shaped projection having a circumferential annular groove, the ring-shaped projection located at an end of the second housing part facing outward from a center of the x-ray emitter housing toward the first housing part,
wherein the radially sealing element is arranged within the circumferential annular groove of the ring-shaped projection, and
wherein the disk spring is arranged between the axially acting threaded ring and the ring-shaped projection, the disk spring configured to maintain pre-stressing forces and prevent settling effects.

2. The x-ray emitter housing of claim 1 , wherein the threaded ring has an outer thread, and the first housing part has a corresponding inner thread.

3. The x-ray emitter housing of claim 1 , wherein the first housing part and the second housing part are connected to one another in the form-fit manner with at least one form-fit element.

4. The x-ray emitter housing of claim 1 , wherein the first housing part is configured to at least partly receive an x-ray tube.

5. The x-ray emitter housing of claim 1 , wherein the second housing part is configured to at least partly receive a drive motor for a rotary anode.

6. The x-ray emitter housing of claim 5 , wherein a stator of the drive motor is arranged on an interior of the second housing part.

7. The x-ray emitter housing of claim 1 , wherein a damping plate is arranged between the first housing part and the second housing part.

8. The x-ray emitter housing of claim 2 , wherein the first housing part and the second housing part are connected to one another in a form-fit manner with at least one form-fit element.

9. The x-ray emitter housing of claim 2 , wherein the first housing part is configured to at least partly receive an x-ray tube.

10. The x-ray emitter housing of claim 2 , wherein the second housing part is configured to at least partly receive a drive motor for a rotary anode.

11. The x-ray emitter housing of claim 10 , wherein a stator of the drive motor is arranged on an interior of the second housing part.

12. An x-ray emitter comprising:
an x-ray tube; and
an x-ray emitter housing comprising:
a first housing part;
a second housing part;
a radially sealing element;
an axially acting threaded ring; and
a disk spring;

wherein the first housing part has a larger diameter than the second housing part, and wherein at least a portion of the first housing part overlaps the second housing part along a radial axis of the x-ray emitter housing,
wherein the first housing part and the second housing part are connected to one another in a form-fit manner with the axially acting threaded ring, wherein the axially acting threaded ring is positioned between the portion of the first housing part that overlaps the second housing part,
wherein the second housing part comprises a ring-shaped projection having a circumferential annular groove, the ring-shaped projection located at an end of the second housing part facing outward from a center of the x-ray emitter housing toward the first housing part,
wherein the radially sealing element is arranged within the circumferential annular groove of the ring-shaped projection,
wherein the disk spring is arranged between the axially acting threaded ring and the ring-shaped projection, the disk spring configured to maintain pre-stressing forces and prevent settling effects, and
wherein the x-ray tube is arranged in the x-ray emitter housing.

13. The x-ray emitter of claim 12 , wherein the threaded ring has an outer thread, and the first housing part has a corresponding inner thread.

14. The x-ray emitter of claim 12 , wherein the first housing part and the second housing part are connected to one another in the form-fit manner with at least one form-fit element.

15. The x-ray emitter of claim 12 , wherein the first housing part is configured to at least partly receive the x-ray tube.

16. The x-ray emitter of claim 12 , wherein the second housing part is configured to at least partly receive a drive motor for a rotary anode.

17. The x-ray emitter of claim 16 , wherein a stator of the drive motor is arranged on an interior of the second housing part.

18. The x-ray emitter of claim 12 , wherein a damping plate is arranged between the first housing part and the second housing part.

19. The x-ray emitter housing of claim 3 , wherein the form-fit element is a feather key, grooved pin, or lug positioned in or on the first housing part or the second housing part.

20. The x-ray emitter housing of claim 1 , wherein the radial sealing element is an O-ring, and wherein the O-ring is configured to be compressed via a bevel, such that contact pressure is evenly distributed onto the O-ring between the first housing part and the second housing part.
