Abstract
The utility model relates to a journal bearing for a rotary anode X-ray tube, which mainly comprises an upper shaft sleeve, a lower shaft sleeve, a shaft rod, a sleeve barrel and a taper sleeve. The upper shaft sleeve is assembled with the top end of the shaft rod with an angle of from 42 to 48 DEG; the lower shaft sleeve is assembled on the shaft rod forming an angle of from 42 to 48 DEG with the taper sleeve; the upper shaft sleeve and the lower shaft sleeve are pressed into a positioning slot of the sleeve barrel. The tail end of the shaft rod and the taper sleeve are welded with the shaft rod into a whole. When a rotating speed of the utility model reaches 14000 RPM, the temperature rise is 10 DEG C. The utility model has the advantages of high stability and low noise. The utility model is assembled on an X-ray tube with large power, and is stable in running in low, middle and high speeds.
Description
One, affiliated technical field:
The utility model relates to a kind of rotating anode X-ray tube, is the rotational slide bearing in a kind of high-power rotational x-ray pipe, belongs to mechanical field.
Two, background technology:
At present, the bulky X ray tube rotarting anode device of the companies such as DUNLEE of U.S. production is even type angular contact bearing of axle.This bearing is to adopt lasso and rolling element structure.This structure assembling back accumulated tolerance is big, and precision is lower, causes the rotarting anode jitter amplitude bigger, and the equipment image quality is poor, and noise is big during work.In order to improve the high temperature resistant greasy property of bearing under high vacuum environment, in the rolling element of bearing and channel surface with soft metals such as method plating molybdenum bisuphide, gold, silver such as vapour deposition, plating, sprayings.Because the solid lubricant film of plating is thinner, cause its lubrication loss very fast, the rate of wear of bearing increases, and temperature rise is increased, and the life-span of bearing reduces, and makes rotarting anode rotate retardance.Cause X-ray tube glass bulb local temperature sharply to raise, cause glass bulb to break, whole X-ray tube is scrapped.
Three, Fa Ming purpose:
The purpose of this utility model provides a kind of sliding bearing that is used for rotating anode X-ray tube, has avoided rotating anode shake, makes equipment image quality height, has reduced the noise of X-ray tube work.Improved the useful life of rotarting anode bearing and X-ray tube, safe and reliable, and meet relative national standards.
Four, Fa Ming content:
The utility model is used for the sliding bearing of rotating anode X-ray tube, comprises axle sleeve, axostylus axostyle, sleeve, tapered sleeve.Adopt MoS

42) steel does axostylus axostyle and tapered sleeve, axially being equipped with of Upper shaft sleeve and axostylus axostyle with 42-48 ° of angle, 5 one-tenth 42-48 of Lower shaft sleeve 2 and tapered sleeve ° angle is fitted on the axostylus axostyle 3, Upper shaft sleeve and Lower shaft sleeve press in the location notch of sleeve reservation, and make the overall strutting piece of bearing with sleeve, terminal and tapered sleeve and axostylus axostyle are welded as a whole with axostylus axostyle.
Five, Fa Ming effect:
The utility model is used for the sliding bearing of rotating anode X-ray tube, shows that by test advantage is:
When rotating speed reaches 14000 rev/mins, temperature rise (about about 10 ℃), the while spin stabilization, noise is little, long service life.And during 7000-8000 rev/min of existing angular contact bearing turn up, temperature rise reaches (the commentaries on classics scooter under the rotating anode high speed operation state is more than 11000 rev/mins) more than 60 ℃.
Six, Brief Description Of Drawings:
Below in conjunction with accompanying drawing the utility model is further described:
This figure is the sliding bearing structure schematic diagram of rotating anode X-ray tube.
Upper shaft sleeve 1 becomes 42-48 ° of angle equipped with the top of axostylus axostyle 3,5 one-tenth 42-48 ° of Lower shaft sleeves 2 and tapered sleeve are fitted to axle On the bar 3, Upper shaft sleeve 1, Lower shaft sleeve 2 press in the locating slot of sleeve 4, and make the integrated support of bearing with sleeve 4 Part is welded as a whole the end of axostylus axostyle 3 and tapered sleeve 5 with axostylus axostyle 3.
Seven, the utility model embodiment:
Upper shaft sleeve 1 is equipped with the angle at 45, top of axostylus axostyle 3, and Lower shaft sleeve 2 is fitted on the axostylus axostyle 3 with tapered sleeve 5 angles at 45, and the spacing of sleeve 4 and Upper shaft sleeve 1, Lower shaft sleeve 2 is fixed, and Upper shaft sleeve 1, Lower shaft sleeve 2 press in the location notch of sleeve 4.Tapered sleeve 5 is used for fixing the position of Lower shaft sleeve 2 at axostylus axostyle 3, simultaneously Lower shaft sleeve 2 is played axial support effect (the radial support effect is also arranged), and tapered sleeve 5 ends are welded on the axostylus axostyle 3.Upper shaft sleeve 1 and Lower shaft sleeve 2 are to use MoS
2, W, Mo, metals such as Nb, Ta self-lubricating composite make, axostylus axostyle 3 tapered sleeves 5 are with the high W of wear-resisting red hardness
