Description
Technical Field
[0001] This invention relates to the field of X-ray tube technology, specifically to a rotating anode X-ray tube anode assembly. Background Technology
[0002] Rotating anode X-ray tubes are assembled in most medical imaging diagnostic devices used for X-ray imaging diagnosis. In a rotating anode X-ray tube, the anode rotates at high speed within a high-vacuum housing, and the electron beam collides with the rotating anode target and releases X-rays from the anode target.
[0003] The auxiliary bearing of the X-ray tube plays a crucial role in bearing the weight of the target disk and enabling anode rotation. During high-intensity operation, the target disk not only transfers a large amount of heat, but its high-speed rotation also leads to additional friction and heat accumulation. These factors make the auxiliary bearing component the most prone to failure in a rotating anode X-ray tube. First, the auxiliary bearing needs to maintain stability under extremely high temperatures and loads. Thermal expansion and deformation caused by prolonged operation may affect its structural integrity. Second, the continuous accumulation of heat may lead to a decline in the performance of the lubricating oil, thereby increasing friction and further aggravating wear.

[0015] This invention provides a rotating anode X-ray tube anode assembly. Compared with the prior art, it has the following advantages: 1. In this invention, when the target disk rotates at high speed through the connecting shaft, the stability of the target disk during rotation is ensured by the cooperation of multiple balls in the bearing assembly. At the same time, the heat generated by the rotation of the balls is transferred to the heat-conducting arc plate through multiple heat-conducting connecting rods. The heat on the heat-conducting arc plate is directly dispersed to the heat dissipation fins. The heat can be quickly dissipated through the heat dissipation fins. This thermal management mechanism significantly extends the service life of the bearing assembly and reduces the risk of failure due to overheating. At the same time, the good heat dissipation effect also ensures the stable operation of the X-ray tube under high load. 2. In this invention, when the connecting shaft drives the target disk to rotate, it will synchronously drive the rotating gear to rotate. Through the meshing of the rotating gear and the auxiliary gear, the auxiliary gear will rotate synchronously. When the auxiliary gear rotates, it will be limited by the auxiliary bearing, thereby using the auxiliary rotating rod to drive the fan blades to rotate at high speed. The airflow generated by the fan blades blows into the interior of the heat dissipation fins. Through the downward airflow, the heat between the heat dissipation fins can be quickly dissipated, which greatly improves the service life of the auxiliary bearing and the stable operation of the X-ray tube. 3. In this invention, when the auxiliary rotating rod rotates, it drives the small gear to rotate. The small gear meshes with the large gear on the connecting shaft. When the large gear rotates, it drives the auxiliary connecting rod to move through the first T-shaped shaft. Through the cooperation of the auxiliary connecting rod and the second T-shaped shaft, the auxiliary vertical plate and the auxiliary slide are limited. During the reciprocating horizontal movement of the auxiliary vertical plate, it drives the cleaning plate to move through the auxiliary connecting rod. The cleaning plate can effectively clean the dust between the heat dissipation fins, effectively improving the heat dissipation effect of the heat dissipation fins and the performance of the auxiliary bearing.
[0016] 4. In this invention, when the auxiliary vertical plate slides within the auxiliary slide groove, it drives the auxiliary slide to move synchronously. Through the limiting sliding of the auxiliary slide and the auxiliary vertical groove, the cooperation between the auxiliary slide and the auxiliary rotating rod, and the cooperation between the auxiliary rotating rod and the U-shaped frame, the stability of the auxiliary vertical plate during horizontal movement is ensured. At the same time, the auxiliary spring of the lower fixed rod is fixedly connected to the upper fixed rod, thereby ensuring the stability of the auxiliary rotating rod during movement. With the cooperation of this structure, the cleaning plate can maintain a good contact state during movement, thereby effectively removing dust and impurities between the heat dissipation fins and improving the performance of the X-ray tube anode assembly.

A bearing assembly 3 is fixedly installed inside the fixed sleeve 2. A connecting shaft 5 is fixedly installed on the bearing assembly 3 via bolts 4. The connecting shaft 5 is fixedly installed to the target disk 1 via nuts 6. The bearing assembly 3 includes a bearing outer sleeve 301, and a bearing inner sleeve 302 is fixedly installed inside the bearing outer sleeve 301. Multiple balls 303 are movably installed between the bearing outer sleeve 301 and the bearing inner sleeve 302. The bearing outer sleeve 301 is fixedly installed inside the fixed sleeve 2. The connecting shaft 5 is fixedly installed on the bearing inner sleeve 302. An auxiliary assembly is provided on the outside of the fixed sleeve 2. The auxiliary assembly includes a heat-conducting arc plate 7 fixedly installed on the fixed sleeve 2. Heat dissipation fins 8 are fixedly installed on the outer side of the arc plate 7, and multiple heat-conducting connecting rods 9 are fixedly installed on the inner side of the heat-conducting arc plate 7. The end of the heat-conducting connecting rod 9 away from the heat-conducting arc plate 7 extends into the interior of the fixed sleeve 2 and is fixedly connected to the bearing outer sleeve 301. There are multiple heat dissipation fins 8, which are evenly distributed and arranged in a ring. There are also multiple ball bearings 303, which are all in sliding contact. The ball bearings 303 are used to ensure the stability of the target plate 1 when rotating. The heat-conducting arc plate 7 and the heat-conducting connecting rods 9 are made of heat-conducting material, and the fixed sleeve 2 is made of heat-resistant material. The structure of the target plate 1 and the heat-resistant and heat-conducting materials are technologies well known to those skilled in the art and will not be described in detail here.
[0021] In this embodiment, when the target disk 1 rotates at high speed through the connecting shaft 5, the stability of the target disk 1 during rotation is ensured by the cooperation of multiple balls 303 in the bearing assembly 3. At the same time, the heat generated by the rotation of the balls 303 is transferred to the heat-conducting arc plate 7 through multiple heat-conducting connecting rods 9. The heat on the heat-conducting arc plate 7 is directly dispersed to the heat dissipation fins 8. The heat can be quickly dissipated through the heat dissipation fins 8.

A guide block 35 is fixedly installed on the outer side of the fixed sleeve 2. The rotating gear 15 meshes with the auxiliary gear 13. The auxiliary gear 13 is positioned above the bracket plate 10, and the fan blade 14 is positioned below the bracket plate 10. The fan blade 14 is positioned directly above the heat dissipation fins 8. The auxiliary gear 13 and the rotating gear 15 are on the same horizontal plane to ensure that the rotating gear 15 can drive the auxiliary gear 13 to rotate when rotating. Both the rotating gear 15 and the auxiliary gear 13 are positioned below the target plate 1 to ensure that the target plate 1 is not affected during rotation. The guide block 35 can dissipate the heat carried away by the airflow to the surroundings by utilizing the guiding effect of the guide block 35.
[0023] In this embodiment, when the connecting shaft 5 drives the target disk 1 to rotate, it will synchronously drive the rotating gear 15 to rotate. Through the meshing of the rotating gear 15 and the auxiliary gear 13, the auxiliary gear 13 will rotate synchronously. When the auxiliary gear 13 rotates, it will be limited by the auxiliary bearing 11, thereby using the auxiliary rotating rod 12 to drive the fan blade 14 to rotate at high speed. The airflow generated by the fan blade 14 blows into the interior of the heat dissipation fins 8. Through the downward airflow, the heat between the heat dissipation fins 8 can be quickly dissipated, which greatly improves the service life of the auxiliary bearing 11 and the stable operation of the X-ray tube.

The rotatable upper fixing rod 28 and lower fixing rod 34 ensure the reaction force of the auxiliary spring 29, so that the entire structure can move stably.
[0027] In this embodiment, when the auxiliary vertical plate 23 slides within the auxiliary slide groove 22, the auxiliary vertical plate 23 will drive the auxiliary slide 31 to move synchronously.

[0028] Working principle: When the target disk 1 rotates at high speed via the connecting shaft 5, the cooperation of multiple balls 303 in the bearing assembly 3 ensures the stability of the target disk 1 during rotation. Simultaneously, the heat generated by the rotation of the balls 303 is transferred to the heat-conducting arc plate 7 through multiple heat-conducting connecting rods 9. The heat on the heat-conducting arc plate 7 is directly dispersed to the heat dissipation fins 8, which quickly dissipate the heat. This thermal management mechanism significantly extends the service life of the bearing assembly 3 and reduces the risk of failure due to overheating. Furthermore, it utilizes a good... The heat dissipation effect also ensures the stable operation of the X-ray tube under high load. When the connecting shaft 5 drives the target disk 1 to rotate, it will synchronously drive the rotating gear 15 to rotate. Through the meshing of the rotating gear 15 and the auxiliary gear 13, the auxiliary gear 13 will rotate synchronously.

Through the downward airflow, the heat between the heat dissipation fins 8 can be quickly dissipated. When the auxiliary rotating rod 12 rotates, it will drive the pinion gear. 16 rotates, utilizing the small gear 16 meshing with the large gear 19 on the connecting shaft 18. When the large gear 19 rotates, it drives the auxiliary connecting rod 21 to move via the first T-shaped shaft 20. Through the cooperation of the auxiliary connecting rod 21 and the second T-shaped shaft 24, the auxiliary vertical plate 23 is limited in position with the auxiliary slide 22. During the reciprocating horizontal movement of the auxiliary vertical plate 23, it drives the cleaning plate 27 to move via the auxiliary connecting rod 26.

At the same time, the auxiliary spring 29 of the lower fixed rod 34 is fixedly connected to the upper fixed rod 28, thereby ensuring the stability of the auxiliary rotating rod 12 when it moves. With the cooperation of this structure, the cleaning plate 27 can always maintain a good contact state during the movement, thereby effectively removing dust and impurities between the heat dissipation fins 8 and improving the performance of the X-ray tube anode group.
