Description of the drawings
Accompanying drawing 1 is the structural representation of the present invention;
Attached drawing 2 is upper and lower annulus grinding treated disk spring schematic diagram.
Specific embodiment
Illustrate with reference to each figure, a kind of inclined-plane thrust bearing shoe valve with elastic support structure, by inclined-plane thrust bearing shoe valve 1, disk spring
2nd, positioning column 3 and retainer 4 form；It is characterized in that at each angle of geometric center and surrounding of retainer 4,5 positioning columns are installed altogether
3, butterfly spring 2 is installed on each positioning column 3；Inclined-plane thrust bearing shoe valve 1 is put into the holding for being assembled with positioning column and butterfly spring
On frame 4, and top board 10 is welded, constitute a kind of inclined-plane thrust bearing shoe valve with elastic support structure.The inclined-plane thrust bearing shoe valve 1
For fan-shaped tile fragment, at the inside and outside distribution rounded edge of fan-shaped tile fragment, flange 9 is processed, fan-shaped tile fragment bottom surface is in positioning column point
At the position of cloth, locating and machining column can enter respectively circular groove 5,5 depth of circular groove be more than 2 maximum compressibility of butterfly spring with it is fixed
Position column 3 enters the sum of circular groove initial depth.Processing and inclined-plane thrust bearing shoe valve flange on the inside and outside distribution circular bosses of the retainer 4
9 matched grooves 8 match somebody with somebody and are combined into clearance fit；5 circular grooves 7 are processed in retainer bottom surface, circular groove is distributed in retainer 4
Geometric center and circumferential four edges for being symmetrically distributed in retainer, countersunk seat 6 is processed on circular groove, ensures countersunk seat bottom
The flatness in face.The positioning column 3 is respectively installed in the circular groove on retainer 4, is interference fit with circular groove；Positioning column 3
It highly should ensure that it can enter the initial depth of inclined-plane thrust bearing shoe valve bottom surface circular groove 5 for 1 ~ 3mm after inclined-plane thrust bearing shoe valve is installed；It is described
Butterfly spring 2 upper and lower annulus, carry out grinding processing, ensure the flatness of grinding surface 11 and lower grinding surface 12 thereon；And
Center pressurization and partially auxobaric performance test are carried out to disk spring 2 after grinding, it is ensured that the butterfly spring circumference of selection is each
Directional stiffness is identical, and the axial rigidity of center disk spring 2 is more than the axial rigidity of the butterfly spring of surrounding distribution, according to axis
The theoretical calculation and analog simulation for holding actual use operating mode lower inclined plane thrust bearing shoe valve load stress use various rule as a result, reasonably selecting
The butterfly spring of lattice.Inclined-plane thrust bearing shoe valve 1 is put into retainer 4, is supported by disk spring, in the limit of retainer after welding pressing plate 10
Under system, inclined-plane thrust bearing shoe valve only has there are one watt degree of freedom in thick direction, and inclined-plane thrust bearing shoe valve 1 will partly be pressed after load is born
Enter in retainer 4;
Operation principle：The present invention when unbalance loading phenomenon occurs, bears the larger inclined-plane thrust bearing shoe valve of load in bearing operational process,
The compression degree of its butterfly spring is big, and the part that inclined-plane thrust bearing shoe valve 1 is pressed into retainer 4 increases, and increases itself and thrust disc runner plate
Distance, alleviate unbalance loading caused by lubricating oil film it is drastically thinning the phenomenon that；Inclined-plane thrust bearing shoe valve 1 uses center and surrounding totally 5 dish
According to the application operating mode of bearing, first, the non-uniform pressure of inclined-plane thrust tile-base surface is calculated by simulation in shape spring-loaded
The distribution in field and temperature field and suitable bearing shell deformation range, then, the change of bearing shell are simulated using structure simulation software
Shape, by suitably choosing the butterfly spring of support inclined thrust bearing shoe valve, control inclined-plane thrust bearing shoe valve 1 is maintained at the change formed beneficial to oil film
In the range of shape, bearing lubrication performance is improved;
The inventive structure is simple, and inclined-plane thrust bearing shoe valve 1 is supported by 5 disk springs of center and surrounding, realizes inclined-plane thrust bearing shoe valve 1
Elastic bearing, make it have it is good carry performance, improve due to thrust disc runner plate axis offset, bearing fitted position mistake
The factors such as poor, bearing vibration, cause the unbalance loading of bearing, caused axis excessive so as to cause indivedual 1 stress of inclined-plane thrust bearing shoe
Hold deterioration extent；By rationally choosing to install the butterfly spring 2 at 1 center of inclined-plane thrust bearing shoe valve and surrounding, realize and inclined-plane thrust bearing shoe valve 1 is become
The control of shape ensures bearing shell deformation in the scope formed beneficial to hydrodynamic lubrication oil film, so as to improve the profit of tapered-land thrust bearing
Slip energy and use reliability extend the working life of bearing.
