In conjunction with shown in Fig. 2 to Fig. 5: the outer circumference surface of described bearing inner sleeve 42 and left and right end face are respectively provided with the slot type of regular shape Decorative pattern 43 (such as 431 in figure, 432 and 433, the slot type decorative pattern in the present embodiment is impeller shape), and the groove of left side Formula decorative pattern 432 forms specular with the slot type decorative pattern 433 of right side.It is positioned at the slot type decorative pattern of the outer circumference surface of bearing inner sleeve 42 The axial profile line of 431 is respectively formed one_to_one corresponding phase with the radial profile of the slot type decorative pattern (432 and 433) of left and right end face Handing-over mutually, it may be assumed that the axial high bit line 4311 in the slot type decorative pattern 431 of outer circumference surface and the slot type decorative pattern (432 of left and right end face With 433) in the high bit line of radial direction (4321 and 4331) the most corresponding and mutually join before end face peripheral chamfer；Excircle In axial neutrality line 4312 in the slot type decorative pattern 431 in face and the radial direction in the slot type decorative pattern (432 and 433) of left and right end face Bit line (4322 and 4332) is the most corresponding and mutually joins before end face peripheral chamfer；The slot type decorative pattern 431 of outer circumference surface In axial low-bit line 4313 and the radial direction low-bit line (4323 and 4333) in the slot type decorative pattern (432 and 433) of left and right end face The most corresponding and mutually join before end face peripheral chamfer.

The slot type decorative pattern (431,432 and 433) of regular shape it is respectively provided with by the outer circumference surface and both ends of the surface making bearing inner sleeve 42, The slot type decorative pattern 432 of left side and the slot type decorative pattern 433 of right side form the slot type decorative pattern 431 of specular and outer circumference surface Axial profile line is respectively formed one_to_one corresponding with the radial profile of the slot type decorative pattern (432 and 433) of left and right end face and mutually joins, Can ensure that pressurization gas produced by the slot type decorative pattern (432 and 433) of the impeller shape of both ends of the surface is the most past from axle center Carrying in the recess channels that the slot type decorative pattern 431 of outer circumference surface is formed, running up the gas needed for bearing so that forming higher support Film, and air film is i.e. as the lubricant of kinetic pressure gas journal bearing, is thus advantageous to realize described slot type kinetic pressure gas journal bearing The 4 high speed steady runnings under air supporting state.

It addition, when being respectively provided with stop ring 44 at the two ends of bearing outside 41, may be implemented under the drive of high speed gyroaxis, make Being produced from sealing function between the both ends of the surface of bearing inner sleeve 42 and stop ring 44, the action pneumatic physical ability making slot type decorative pattern continuously generate is intact In the airtight whole fit clearance being saved in bearing in ground, fully ensure that the lubrication needs of the kinetic pressure gas journal bearing run up.

Fit clearance between described bearing outside 41 and bearing inner sleeve 42 is preferably 0.003～0.008mm, to further ensure that axle Hold the reliability and stability run up.

As shown in Figure 6: the hybrid kinetic pressure gas thrust bearing of one 5 that the present embodiment provides, including: two side panels 51, It is folded with mid-game 52 between two side panels 51, between each side panel 51 and mid-game 52, is provided with foil-type elastic component 53；In described The left side of dish 52 is provided with the slot type decorative pattern 521 of regular shape, and right side is provided with the slot type decorative pattern 522 of regular shape.

Visible in conjunction with Fig. 7 a and Fig. 7 b: the slot type decorative pattern 521 of the left side of described mid-game 52 and the slot type decorative pattern 522 of right side Between form specular, the radial direction wheel of the radial profile of the slot type decorative pattern 521 of left side and the slot type decorative pattern 522 of right side Profile forms one_to_one corresponding.

Described slot type decorative pattern 521 is identical with the shape of 522, is impeller shape in the present embodiment.

Visible further combined with Fig. 8 a and Fig. 8 b: described foil-type elastic component 53 is fixed on the inner face of corresponding side panel 51 (such as The right side being fixed with foil-type elastic component 53b shown in left hand plate 511 and Fig. 8 b being fixed with foil-type elastic component 53a shown in Fig. 8 a Side panel 512), and the foil-type elastic component 53a being fixed in the left hand plate 511 and foil-type elastic component 53b being fixed on the dish 512 of right side Form specular.Foil-type elastic component on each side panel can be multiple (shown in figure are 4), and along the inner of side panel Face is uniformly distributed.

By arranging foil-type elastic component 53 between side panel 51 and mid-game 52, the left and right end face in mid-game 52 arranges rule shape The slot type decorative pattern (521 and 522) of shape, and make the slot type decorative pattern 521 of left side form mirror image with the slot type decorative pattern 522 of right side Symmetry, thus obtained the rigidity characteristic of the high limit rotating speed not only with slot type kinetic pressure gas thrust bearing, but also there is paillon foil formula moved The high impact-resistance of pressure gas lubricated thrust bearing and the hybrid kinetic pressure gas thrust bearing of the flexible characteristic of load-carrying ability；Because paper tinsel Defining wedge shape space between type elastic component 53 and mid-game 52, when mid-game 52 rotates, gas is carried because of the viscous effect of himself Move and be compressed in wedge shape space, thus axial hydrodynamic power can be made to been significantly enhanced, moving relative to existing simple paillon foil formula Pressure gas lubricated thrust bearing, can have the limit speed being multiplied under same load；Simultaneously as add foil-type elastic component 53, under its elastic reaction, the ability of the load-carrying ability of bearing, impact resistance and suppression axle whirling motion also can be made to significantly improve, Relative to existing simple slot type kinetic pressure gas thrust bearing, can have the impact resistance and load being multiplied under same rotational speed Lotus ability.

Shown in Fig. 6 and Fig. 9, Figure 10: described foil-type elastic component 53 is made up of ripple paper tinsel 531 peace paper tinsel 532, described The top of the arc convex 5311 of ripple paper tinsel 531 fits with flat paper tinsel 532, transition base 5312 between the ripple arch of described ripple paper tinsel 531 Fit with the inner face of corresponding side panel 51.

For reducing the mid-game 52 the run up abrasion to foil-type elastic component 53 further, to extend the service life of bearing, On the cooperation face of the foil-type elastic component 53 fortunately matched with mid-game 52, wear-resistant coating (not shown) is set.
