Description
Technical field
The present invention relates to a kind of pallet, and in particular to a kind of elastic bearing support deformed with load change controllable-thrust watt
Disk, applied to the tilting thrust bearing by tray supporting.
Background technology
Thrust slide bearing leans on formation dynamic pressure oil film between thrust bearing shoe valve and runner plate to play carrying effect, oil film pressure and oil film
Temperature can cause the deformation of thrust bearing shoe valve.Research shows：Suitable thrust bearing shoe valve deformation is conducive to the raising of bearing lubrication performance；Bearing shell
Deformation is excessive, is unfavorable for the formation of dynamic pressure oil film, reduces the use reliability of bearing.For the thrust bearing shoe valve that inclines of dot point
Say, when tile fragment size is larger and bears compared with big load, is easily caused thrust bearing shoe valve and produces moderate finite deformation, therefore often take in thrust bearing shoe valve
Between bearing stud, increase pallet deforms to reduce thrust bearing shoe valve.Accordingly, it would be desirable to rationally design pallet to control thrust bearing shoe valve to become
Shape, for carrying small thrust bearing shoe valve, because itself deformation is small, it cannot be beneficial to oil film on the contrary using the larger tray supporting of size
The tray supporting of the deformation of formation, the at this moment suitable use small size of thrust bearing shoe valve.For carrying big thrust bearing shoe valve, because its deformation is big,
Large-sized tray supporting is needed to use to reduce thrust bearing shoe valve deformation.It is big to carrying excursion, and the thrust that carrying often changes
Watt, according to small size tray supporting, when carrying increase, it is impossible to the reduction for controlling bearing shell to deform, according to large scale pallet
Supporting, when carrying small, bearing shell deformation is too small or indeformable, is unfavorable for the formation of bearing lubrication oil film, so as to influence bearing
Use reliability and service life.
The content of the invention
It is an object of the present invention to realize the thrust bearing shoe valve that inclines controlled during carrying is continually changing by tray supporting

Embodiment
With reference to each figure explanation, a kind of elastic bearing pallet (1) deformed with load change controllable-thrust watt, by tray main body
Disk spring (1-4,1-5) composition of (1-1), middle pallet (1-2), small pallet (1-3) and two different sizes；It is characterized in that support
Pallet (1-2) in being placed in disc main body (1-1), middle pallet is by disk spring (1-5) jack-up；Small support is placed in middle pallet (1-2)
Disk (1-3), small pallet is by disk spring (1-4) jack-up；Disk spring (1-5) rigidity of pallet, which is more than, in supporting supports small pallet
Disk spring (1-4) rigidity.Described tray main body center locating and machining axle (1-1-1), locating shaft is highly less than pallet master
Body upper ring surface.Described tray main body centralized positioning axle (1-1-1) coordinates with middle pallet (1-2), small pallet (1-3) for gap.
Described small pallet (1-3) is by the upper ring surface of butterfly spring (1-4) supporting pallet in prominent, and thrust bearing shoe valve (3) can be by small pallet (1-
3) upper ring surface is pressed onto is in same plane with middle pallet (1-2) upper ring surface.Described middle pallet (1-2) is by disk spring (1-5)
The upper ring surface of the prominent tray main body of supporting, thrust bearing shoe valve (3) middle pallet (1-2) upper ring surface can be pressed onto with tray main body (1-1)
Anchor ring is in same plane.The upper and lower surface of described butterfly spring will carry out grinding processing, it is ensured that thereon, lower surface it is parallel
With the flatness of two planes；And center pressurization and partially auxobaric performance test are carried out to the disk spring after grinding, it is ensured that choosing
Butterfly spring is axially identical with circumference all directions rigidity；On same bearing, the dish that each thrust bearing shoe valve supporting tray is selected
Shape spring performance should be relatively.
Operation principle：The present invention is placed between bearing stud (2) and thrust bearing shoe valve (3), control thrust bearing shoe valve deformation is played
Effect.Thrust bearing shoe valve is from underloading into heavily loaded change procedure：When thrust bearing shoe valve (3) bears underloading, thrust bearing shoe valve (3) is only by small pallet
(1-3) is supported, and is not contacted with middle pallet (1-2) and tray main body (1-1), and due to thrust bearing shoe valve, to bear load small, tiling deform it is small,
In this case, only supporting thrust bearing shoe valve by small pallet (1-2), suitable thrust bearing shoe valve deformation can be obtained.Increase with load, thrust bearing shoe valve
Deflection increase, if being continuing with small pallet, bearing shell deformation is excessive to be unfavorable for the formation of oil film, in this case, supporting small pallet
Disk spring (1-4) be pressurized and shrink, anchor ring is forced on small pallet (1-3) is in one with anchor ring on middle pallet (1-2)
Individual plane, middle pallet and small pallet support thrust bearing shoe valve jointly, and increased effect is deformed with load increase containment thrust bearing shoe valve to reach,
Thrust bearing shoe valve is set to be maintained in suitable deformation range.Continue to increase with load, thrust bearing shoe valve deformation will also have increase trend, this situation
Under, the disk spring (1-5) of pallet, which is pressurized, in supporting shrinks, the upper ring surface of small pallet (1-3) and middle pallet (1-2) be forced into
Tray main body (1-1) upper ring surface is in a plane, and small pallet, middle pallet and tray main body support thrust bearing shoe valve jointly, and control is pushed away
Power watt remains in that the deformation range suitable for dynamic pressure oil film formation under heavy loads.Thrust bearing shoe valve is from heavy duty into underloading change procedure：
First, middle pallet (1-2) is first by disk spring (1-4) jack-up；Then, small pallet (1-3) is by disk spring (1-5) jack-up, control
Controlling push-force watt is in being beneficial in the deformation range of dynamic pressure oil film formation under the effect of various load.So as to the lubricity of bearing
Can and it be improved using reliability.
The present invention, when load changes, passes through adjust automatically pallet (1) and thrust bearing shoe valve in bearing running
(3) bearing contact areas, realizes to the thrust bearing shoe valve Deformation control of inclining by tray supporting, remains thrust bearing shoe valve (3)
Beneficial to the deformation range of oil film formation, improve bearing lubrication performance and use reliability；The tray main body (1-1) of the present invention is not
When contacting thrust bearing shoe valve (3), because small pallet (1-3) and middle pallet (1-2) are by butterfly spring elastic (1-4,1-5) supporting, its
With certain load performance.
