Description
Technical field
The present invention relates to machinery field more particularly to a kind of swash plate devices of variable compressor.
Background technology
Inclined disc type variable displacement automobile air-conditioning compressor can be automatic according to vehicle interior temperature under any rotating speed of automobile engine
The discharge capacity of compressor is adjusted, efficiency and comfort are substantially better than fixed displacement compressor, and therefore, medium-to-high grade Car Air Conditioning System is got over
Carry out the inclined disc type variable compressor of more uses, therefore the noise and vibration problem of inclined disc type side capacity compressors causes increasingly
More concerns.Through analysis it is found that the convenient noise source of compressor machinery includes between the unbalance dynamic of swash plate and piston shoe
Friction impact.
Therefore, it is necessary to a kind of swash plate device of variable compressor to alleviate the unbalance dynamic problem of swash plate, solved with this
Certainly noise problem.
Invention content
For the deficiencies in the prior art, the present invention provides a kind of swash plate device of variable compressor, alleviates oblique
The unbalance dynamic problem of disk solves engine noise problem caused by swash plate.
The technical scheme is that：A kind of swash plate device of variable compressor, it is characterised in that：Including turntable, angle
Spend adjustment disk, link block, swash plate and shaft.
Shaft sequentially passes through turntable, angular adjustment disk and swash plate；Link block one end is connect with turntable, the other end and angle tune
Save disk connection.
Turntable is fixed on by gasket and nut in shaft.Gasket includes an annulus, and annulus is uniformly distributed on peripheries with five leaves
Piece；Annulus center is equipped with the stud containing internal and external threads；The external screw thread of stud is adapted to nut, and internal thread is adapted with shaft.
Stud is tightened across turntable with nut；Shaft passes through stud.Turntable is fixed in shaft by gasket and nut, can not be moved.Turn
The bottom of disk is equipped with limiting slot corresponding with gasket.And five blades of gasket limit the loosening of gasket.
Link block includes fixed seat and fixed block, and fixed seat is sector；Fixed block is rectangle；Fixed block is fixed on fixed seat
On.
Fixed seat is equipped with through-hole, and through-hole is arc-shaped.When arc is that angular adjustment disk adjusts angle, on fixed block
The track streaked.The bolt slided along through-hole is equipped in through-hole.
Angular adjustment disk is cone, and coning angle is 150 degree.Angular adjustment disk changes traditional swash plate or so quality not
Together, structure is different, and barycenter is caused to deviate central shaft, and larger unbalance dynamic is fluctuated to generate.When swash plate not run-off the straight, angle
Spend the symmetrical of adjustment disk；When the inclination angle of swash plate is 30, the barycenter of angular adjustment disk is also closer from shaft.It effectively reduces
The noise that unbalance dynamic generates.
Allow the angle that angular adjustment disk changes in the range of 0-30 degree.The section of angular adjustment disk is annulus,
Section radially sets that there are one the openings that are adapted to fixed block.Fixed block insertion opening completes link block and angular adjustment disk
Connection.The opposite edge with being open, if there are one along element of cone raised line.The raised line for connect angle adjustment disk with tiltedly
Disk.
The center of angular adjustment disk is set there are two opposite bowed fixinig plate, and the side of fixinig plate is equipped with turn hole；Two
The centre of fixinig plate is set there are one rotatable lamella, and the both ends of rotatable lamella are equipped with pillar, and pillar is inserted in rotation in turn hole；Shaft, which passes through, moves
Movable plate is fixed thereto；
When angular adjustment disk changes angle, the position of shaft keeps vertical constant, and the pillar of rotatable lamella is in turn hole
The angle change of angular adjustment disk is realized in rotation.Swash plate is equipped with the card slot of bar shaped, and card slot is adapted to raised line.
Further, spring is cased in the shaft below swash plate, the lower end of spring is fixed in shaft.Spring
Setting, when swash plate needs to swing up and down change angle tilt angle with angular adjustment disk, spring plays cushioning effect；Together
When, spring also functions to position-limiting action, prevents swash plate from falling from shaft.
Further, angular adjustment disk is equipped between the side and swash plate of opening and is equipped with second spring.With spring
It stretches and either compresses angular adjustment disk under tension or support force, so that angular adjustment disk is stabilized in link block and swash plate
Between.
Further, the thickness of limiting slot is less than the thickness of gasket.Gasket is in limiting slot, due to the thickness of gasket
Thickness, so gasket is higher by the bottom surface of turntable, the blade of gasket can just fix the fixed seat of link block wherein.Design is skilful
It is wonderful.
Further, opening is fixedly connected by bolt with bolt；Wearing layer is equipped in through-hole.Wearing layer is effectively anti-
It is worn when only bolt slides in through-holes.
More into one must, the center of swash plate is equipped with the circular hole that shaft passes through, and circular hole inner circumferential is equipped with a circle asbestos layer.Because tiltedly
Disk needs to change inclination angle, so relative position of the shaft in circular hole is can be changed.Asbestos fibre high resilience, asbestos
Have acidproof, alkaline-resisting and heat resistance, and is the non-conductor of heat and electricity.Asbestos layer decreases the friction between shaft and swash plate
Noise.
Advantageous effect：A kind of swash plate device of variable compressor of the present invention, angle regulator of swash plate or so pair
Claim, within the scope of adjustable angle, barycenter reduces the noise caused by unbalance dynamic close to shaft.

The stretching of spring either 2 under tension of compression angular adjustment disk or support force, so that angular adjustment disk 2 is stabilized in link block 3
Between swash plate 4.
Further, the thickness of the limiting slot 11 is less than the thickness of gasket 6.Gasket 6 is embedded in limiting slot 11, due to
The thickness of gasket 6 is thick, so gasket 6 is higher by the bottom surface of turntable 1, the blade 62 of gasket 6 can be just by the fixed seat of link block 3
31 fix wherein.It is ingenious in design.
Further, the opening is fixedly connected by bolt with the bolt；Wearing layer is equipped in the through-hole.
The wearing layer is worn when bolt being effectively prevent to slide in through-holes.
More into one must, the center of the swash plate 4 is equipped with the circular hole 42 that shaft 5 passes through, and 42 inner circumferential of the circular hole is equipped with one
Enclose asbestos layer 43.Because swash plate 4 needs to change inclination angle, relative position of the shaft 5 in circular hole 42 is can be changed.
Asbestos fibre high resilience, asbestos have acidproof, alkaline-resisting and heat resistance, and are the non-conductors of heat and electricity.Asbestos layer is also reduced
Friction noise between shaft 5 and swash plate 4.
Specific implementation process is：Swash plate 4 changes angle under the action of solenoid valve, acts on swash plate 4, and swash plate 4 pushes
Angular adjustment disk 2, when need to angle occur for angular adjustment disk 2, the position of shaft 5 keeps vertical constant, rotatable lamella 22 it is convex
Column rotates in turn hole；Correspondingly, bolt 33 slides in the through-hole of fixed seat, angular adjustment is completed..
