Description

Technical Field

[0001] The utility model relates to the field of bearings, in particular to a ball bearing used for a CT machine tube. Background Art

[0002] The ball bearings of CT tubes are a crucial component of CT systems, ensuring the stable and efficient operation of the X-ray tube (also known as the tube). Ball bearings reduce friction through rolling contact, allowing the anode target to rotate smoothly and with minimal wear at high speeds. This design is particularly important for the continuous, rapid rotation of X-ray tubes required for CT scanning. In short, the ball bearings of CT tubes are a crucial component of CT systems, ensuring the stable and efficient operation of the X-ray tube.

[0003] After extensive searching, we found that the ball tube bearings in CT machines in the prior art will rapidly heat up as the CT machine is running, causing the temperature of the inner and outer rings of the bearings to rise, which may cause the inner and outer rings of the bearings to expand, so that the bearings may lock, affecting the use of the CT machine. Therefore, based on the above search and combined with the prior art, a ball bearing for the ball tube of a CT machine is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 A ball bearing for a CT tube includes an inner ring 1, an outer ring 3 is provided on the outer circumferential surface of the inner ring 1, and a plurality of ball bodies 2 are rotatably connected between the inner ring 1 and the outer ring 3. The outer circumferential surfaces of the inner ring 1 and the outer circumferential surfaces of the outer ring 3 are both provided with grooves, and the ball bodies 2 roll in the grooves. A cooling ring 10 is fixedly sleeved on the outer circumferential surface of the outer ring 3. The cooling ring 10 is a hollow annular structure. A cooling component 4 for cooling the inner ring 1 and the outer ring 3 is provided on the outer circumferential surface of the cooling ring 10. A heat conducting component 5 for conducting heat to the coolant inside the cooling ring 10 is provided on the top surface of the cooling ring 10.

[0024] The cooling assembly 4 includes two connecting pipes 6, both of which are installed on the outer circumferential wall of the cooling ring 10. The connecting pipe 6 on the left is a liquid inlet pipe, and the connecting pipe 6 on the right is a liquid outlet pipe. The interior of the connecting pipe 6 is rotatably connected to a baffle 15, and a mounting rod 19 is fixedly installed on the top surface of the baffle 15. A connecting hole 18 is provided on the outer circumferential wall of the connecting pipe 6, and the outer circumferential wall of the mounting rod 19 is rotatably connected to the inner circumferential wall of the connecting hole 18. A supporting hole 20 is provided on the outer circumferential wall of the mounting rod 19, and a supporting plate 21 is elastically connected to the supporting hole 20. Two mounting columns 26 for limiting the support plate 21 are fixedly installed inside the support hole 20. The support plate 21 and the mounting rod 19 are fixedly connected. The mounting column 26 is slidably connected, and the outer circular wall surface of the mounting column 26 is sleeved with a spring 27. One end of the spring 27 is fixedly connected to the inner top surface of the support hole 20, and the other end of the spring 27 is fixedly connected to the top surface of the support plate 21. The outer circular wall surface of the connecting pipe 6 is fixedly mounted with a support frame 16. The top surface of the support frame 16 is provided with a plurality of limiting grooves 17. The support plate 21 is movably engaged with the limiting grooves 17. A clamping column 25 is fixedly mounted inside the limiting groove 17. The top surface of the support plate 21 is provided with two clamping holes 24. The outer circular wall surface of the clamping column 25 is movably engaged with the inner circular wall surface of the clamping hole 24. The outer circular wall surface of the mounting rod 19 is provided with a limiting member for limiting the mounting rod 19.

[0025] The limiting member includes a limiting ring 23, which is fixedly sleeved on the outer circumferential wall of the mounting rod 19. The inner circumferential wall of the connecting hole 18 is provided with an annular groove 22 for providing rotation for the limiting ring 23. The limiting ring 23 is rotatably connected to the annular groove 22. The mounting rod 19 is provided, and the rotation of the mounting rod 19 drives the limiting ring 23 to rotate inside the annular groove 22 on the inner wall of the connecting hole 18. The limiting ring 23 and the annular groove 22 can limit the rotation of the mounting rod 19, thereby achieving a limiting effect on the mounting rod 19.

[0026] Through the provided connecting pipe 6, the staff connects one end of the external coolant pipe to the connecting pipe 6 on the left and connects the other end to the connecting pipe 6 on the right, so that the coolant can flow inside the cooling ring 10. The staff moves the support plate 21 upward. The upward movement of the support plate 21 will move upward along the two mounting columns 26 inside the support hole 20 on the mounting rod 19, and at the same time, the spring 27 is compressed. The upward movement of the support plate 21 will move to the outside of the limiting groove 17 on the top surface of the support frame 16. At the same time, the clamping column 25 inside the limiting groove 17 is separated from the clamping hole 24 on the support plate 21. Then the staff rotates the support plate 21 counterclockwise by 90 degrees, driving the mounting rod 19 to rotate counterclockwise by 90 degrees. The mounting rod 19 rotates counterclockwise by 90 degrees, driving the baffle 15 to rotate counterclockwise, so that the baffle 15 is longitudinally in the connecting Inside the tube 6, the staff loosens the support plate 21, and the force of the spring 27 causes the support plate 21 to move downward along the mounting column 26. The downward movement of the support plate 21 will enter the upper limit groove 17 of the support frame 16, and at the same time, the clamping column 25 will enter the clamping hole 24 on the support plate 21, thereby determining the position of the baffle 15, so that the baffle 15 remains longitudinal inside the connecting tube 6. At this time, the coolant enters the interior of the cooling ring 10 through the connecting tube 6 on the left. The coolant flowing inside the cooling ring 10 will take away the heat generated by the rotation of the CT tube on the inner ring 1 and the outer ring 3, and then flow out through the connecting tube 6 on the right, thereby reducing the temperature of the inner ring 1 and the outer ring 3, achieving a cooling effect on the inner ring 1 and the outer ring 3, preventing the CT machine from being difficult to use due to the excessively high temperature of the inner ring 1 and the outer ring 3, and making it easier for the staff to use the CT machine.

[0027] Example 2: Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A ball bearing for a CT tube. A connecting column 9 is fixedly mounted on the outer circumferential wall of the baffle 15. A connecting groove 28 is provided on the inner circumferential wall of the connecting tube 6 for providing a rotation for the connecting column 9. The outer circumferential wall of the connecting column 9 is rotatably connected to the inner circumferential wall of the connecting groove 28. The baffle 15 is provided so that the rotation of the baffle 15 drives the connecting column 9 at the lower end of the baffle 15 to rotate inside the connecting groove 28 on the inner wall of the connecting tube 6. The connecting tube 6 and the connecting groove 28 cooperate to support the rotation of the baffle 15 and prevent the lower end of the baffle 15 from shaking.

[0028] The heat conducting assembly 5 includes a plurality of mounting holes 11, each of which is formed on the top surface of the cooling ring 10. A heat conducting plate 12 for heat conduction is fixedly sleeved inside the mounting hole 11. When the coolant flows through the cooling ring 10, it absorbs heat from the outer ring 3 and its temperature rises. The heat in the coolant is then transferred to the plurality of heat conducting plates 12, and the heat on the heat conducting plates 12 is dissipated into the air, thereby reducing the temperature of the coolant inside the cooling ring 10.

[0029] The inner wall of the inner ring 1 is fixedly sleeved with a protective ring 8, and the inner wall of the protective ring 8 is provided with anti-slip grooves 7. The protective ring 8 can protect the inner wall of the inner ring 1. When the staff installs the inner ring 1 together with the ball body 2 and the outer ring 3 on the tube of the CT machine, the anti-slip grooves 7 can increase the friction between the protective ring 8 and the tube of the CT machine, thereby improving the installation effect of the inner ring 1;

[0030] A fixing ring 13 is fixedly sleeved on the outer circumferential wall of the connecting pipe 6, and a plurality of fixing holes 14 are opened at one end of the fixing ring 13. Through the set fixing ring 13, the staff puts the bolts into the fixing holes 14 on the fixing ring 13, thereby connecting the coolant pipe to the connecting pipe 6.

[0031] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
