温になると劣化分解し炭化物（スラッジ）？発生する。The anode-side Haube and the cathode-side Haube 9 are fixed to a central Haube 11 provided with an X-ray emission window IO. The cathode side wall 9 and the center wall 11 are coated with gold-lead inside to block X-rays. The anode-side Hakubaa is not coated with lead because the rotating magnetic field generator 6 blocks X-rays. The rotating anode X-ray tube device having the above configuration is fixed to a pedestal (not shown) through the central Haube 1lVc. In order to cool the tube 3 and the rotating magnetic field generating device 6, the cathode side Haube 9 is provided with an introduction hole 14A for cooling insulating oil 17, and the Haube 15'li7 is cooled by the cooling insulating oil 17. The cooling insulating oil whose temperature has increased due to heat exchange within the Hawai 15 is taken out from the outlet hole 14B provided in the Haubae on the anode side, cooled outside the Haubai 15 (not shown), and then transferred to the introduction hole 14A again.
will be introduced. Thermionic electrons generated at the cathode 2 are focused and accelerated by applying a high voltage between the cathode 2 and the rotating anode l, and the thermionic electrons collide with the surface of the target 16 of the rotating anode l to generate X-rays. X-rays are extracted from an X-ray emission window 10. The temperature of the target 16 reaches as high as 1400 CK, but since the inside of the tube 3 is completely solid, the gas heat transfer is carried out by the oil, and most of the heat is transferred to the surface of the tube 3 and the insulating cooling oil 17. It can be conveyed in When this insulating cooling oil 17 reaches high temperatures, it deteriorates and decomposes to form carbide (sludge). Occur.

insulation properties deteriorate.

At the other end of this, the distance between the tube 3 and the purchased item in Hawaii 15 is kept sufficiently large to maintain insulation and prevent discharge.

重要な課題である。A solid lubricant is used as a lubricant since the bearing (not shown) inside the rotary anode l rotates at high speed (3000 to 900 rpm) in a high vacuum chamber. At this time, since there is a solid between the balls and the rolling surface of the bearing, the solid lubricant acts as a foreign substance, increasing rotational vibration and noise. In addition, the target 16, which is the collision surface of thermionic electrons, has a temperature of 1400G from room temperature.
Since it is repeatedly heated and cooled until the temperature reaches 100 degrees, the imbalance in the thermal history increases, and an increase in vibration and noise is unavoidable. Normally, rotary anode X-ray tube devices are judged to be defective if the noise level is 60 to 65 dB'/c or more, so reducing vibration noise is an important issue.

It passes through the insulating cooling oil 17 from the entire surface of the tube 3 and spreads to the entire ube 15. In addition, the noise and vibration propagated from the rotating anode l to the lucky ball fixing part 4 are transmitted through the support part 5.

低騒音化に充分ではない。FIG. 3 shows the rotating anode X-ray tube device shown in FIG. 1 mounted on a pedestal (not shown) at the center of the tube 15, and the vibration acceleration at each point of the tube 15 measured. In the axial direction (longitudinal direction) of the Haupe 15, vibration tends to increase from the cathode side to the anode side. However, the vibrations at Central Hakube 11 are small. This is thought to be due to the high rigidity of the center break 11, which acts as a vibration node. On the other hand, looking at the vibration in the radial direction at the end surface 18 of the anode side Haubera, the vibration of the support portion 5 and the anode side Haubera is about the same as the vibration in the axial direction. In other words, the supporting part 5 and the anode side Hakuvea are coupled, and it is clearly shown that the vibration is propagated from the support part 5 to the anode side Hakuvea. In order to reduce noise and imaging, it is effective to reduce vibrations transmitted through a rigid body, that is, vibrations transmitted from the rotating anode to the support portion. There is also a rotating anode X-ray tube device that has an appropriate distribution structure for the tube fixing part 4, support part 5, etc. to reduce noise and vibration, but the vibration damping structure using the viscosity of the insulating cooling oil 17 reduces noise and vibration. The attenuation for high frequency components is small. Human hearing sensitivity is 2
Considering that there is a peak around 000 Hz, the high frequency components of noise and vibration 17) tIIj, attenuation are important,
A vibration damping mechanism that utilizes the viscosity of insulating cooling oil alone is insufficient for noise reduction. In addition, if a vibration-damping structure is made of vibration-proof rubber, it will have a large breakage effect against high-frequency components, but it will be difficult to maintain oil resistance and mechanical structure, and the elasticity of the rubber. The use of anti-photograph rubber is not easy and is not sufficient to reduce the noise of rotating anode X-ray tube devices.

どの問題に対しては効果がない。As a method of reducing noise and vibration using anti-vibration rubber, a method is known in which anti-vibration rubber is interposed in the tube fixing part to damp vibration, as shown in Japanese Utility Model Application Publication No. 58-15999. ing. This method is effective in reducing noise and imaging because it makes it difficult for the noise and vibration energy generated by the rotating anode to be transmitted to Hawaii. It is not effective against problems such as damage to component parts.

The anode side of the tube 3 is fixed by an anode side support member which firmly supports the tube at the tube part 4, and this anode side support member 12 is formed in a cup shape and is arranged to cover the tube 3. It is fixed at the central no-upe 11. Reference numeral 13 is attached to the cathode side of the bulb 3 (a cathode side support member supported by an elastic body 8), and this cathode side support member 13 is also formed in a cup shape, and is disposed to cover the tube bulb 3 and is attached to the central Hawaii 11. These support members 12 and 13 have a predetermined distance from the tube 3, and the support member 13 has an inlet 13A for the cooling insulating oil 17 at the top of its head, and the support member 12 has an inlet port 13A at the top of its head. Outlet ports 12A for the cooling insulating oil 17 are provided in the vicinity of the parts supported by the cooling insulating oil 11. This member supports the 18Vi rotating magnetic field generator 6 and is attached to the central Hawaii 11.

いほどこの効果は大きい。FIG. 5 shows the propagation path of noise and vibration generated within the rotating anode l in the above configuration. Noise and vibration propagating from the rotating anode l to the tube 3 pass through the insulating cooling oil 17 and propagate to the central Hawaii 11, but the tube 3 must be surrounded by a double container of the support member 12 and the anode side Haubera. Therefore, the noise and vibration propagating in the insulating cooling oil 17 are attenuated, and a sound insulation effect is obtained. 9. Silkworm movement propagates from the rotating anode 1 to the support member 12. Since the support member 12 is fixed to the central Hawaii 11, the anode side Haubera does not become a path for noise and vibration.
The noise and vibration of Hawaii 7 on the anode side will be extremely small. Furthermore, the total length of the noise/vibration propagation path of the support member 12 is longer than that of the support portion 5 of FIG. 1. Attenuation due to internal loss of the support member 12 increases as the vibration propagation path becomes longer, so in this embodiment, noise and vibration are attenuated considerably while propagating through the support member 12. In particular, the higher the rigidity of the support member 12, the greater this effect.

いため薄肉軽量化が可能となる。In addition, since the support member 13 on the cathode side also has a structure that covers the tube 3 in the same way as the support member 12 on the anode side, the support member 13 passes from the rotating anode 1 through the tube 3 and the elastic body 8 to the center support member 13. The same effect as in the case of the vibrations propagating through the support member 12 can be obtained with respect to the noise and loud vibrations propagating with the breakout 11. Furthermore, since the cathode-side Haube 9 does not receive any load from the tube 3, it can be made thinner and lighter.
次に、冷却絶縁油１７の流れについて説明する。Next, the flow of the cooling insulating oil 17 will be explained.

起らない。The cooling insulating oil 17μ introduced from the equal-sized hole 14A enters the space between the support member 13 and the tube 3 from the cathode side tube 3 through the inlet 13Ak as shown by the arrow, and then the central oil 11 and the tube 3 It flows between the support member 12 and the tube 3, which creates a space. Then, it flows through the anode side Haubera and the support member 12 fully opened from the outlet 12A, and is led out from the outlet hole 14B. At this time, since each of the above-mentioned spaces, that is, the flow paths, flows without stagnation, no carbide is generated in the high temperature area facing the tube 3. However, some stagnation occurs between the cathode side Haube 9 and the support member 13, but the cooling insulating oil 17 in the stagnation part is the cooled oil that entered from the introduction hole 14A, and the heat-generating tube Since the ball 3 and this stagnation part are separated by the support member 13, the temperature of the stagnation part does not rise so much and the oil does not deteriorate.

。If you are concerned about heat retention in this stagnation area, you may need to open this support member 13ic hole or insert the introduction hole 14A between the cathode side wall 9 and the support member 1 as shown in FIGS. 6 and 7.
If the oil is provided at the stagnation part of the oil holder 3 and introduced along the circumferential direction of the cathode side Haube 9, no oil stagnation will occur at all.
したがって、冷却絶縁油の劣化を防止することができる
。Therefore, deterioration of the cooling insulating oil can be prevented.
