Description
Technical field
The present invention relates to compressor field, especially, it is related to a kind of compressor.
Background technology
In the prior art for current compressor operational shock noise it is big the problem of, flexible slot is opened up on lower flange,
Lower cover is slab construction, because the powdered metallurgical material intensity that lower flange is used is relatively low, it is difficult to open up out full on lower flange
Foot require flexible slot, processing efficiency can be reduced using ironcasting again, at the same the non-processing face of cast iron materials easily occur burr,
The phenomenon that the impurity such as residue, oxide skin come off, comes off from cast iron lower flange surface, is likely to enter cylinder, cause compressor card
Extremely, compressor reliability is reduced.
And comprehensive machining is carried out to ironcasting lower flange outer surface can only then carry out milling by Digit Control Machine Tool,
Efficiency is extremely low, and productive temp is very slow, so as to improve production cost；When lower flange serves as the structure of bearing, compression
The aligning of machine（Adjust the relative rigging position of lower cylinder and lower flange so that lower cylinder center and the center of flange ensure permitting
Perhaps in the margin of tolerance）By two screws by after lower cover, lower flange, lower cylinder locking, then adjust with upper cylinder and upper flange
Part after the heart carries out the conjunction heart, and the process of aligning is because bearing is on lower flange, but screw is but pressed on lower cover, is led
There is lower cover, lower flange, lower cylinder because aligning causes screw hole and upper cylinder screw eccentric in cause, causes screw to screw tired
Difficulty, or even there is the problem of pump housing is stuck, so as to reduce efficiency of assembling.
The content of the invention
Present invention aims at a kind of compressor is provided, to solve the technical problem that vibration of compressor noise is big.
To achieve the above object, the invention provides a kind of compressor, including：Bent axle；Upper flange, is set on bent axle；
Lower cover, is set on bent axle by bearing arrangement, and flexible slot is arranged on bearing arrangement.
Further, flexible slot is arranged on the thrust surface contact jaw of lower cover and bent axle.
Further, in addition to the lower flange that is set on bent axle, lower flange is set between upper flange and lower cover, under
The hardness of cover plate is more than the hardness of lower flange.
Further, lower cover is cast-iron structure, and lower flange is powder metallurgy structure.
Further, flexible slot is along the circumferentially disposed of bent axle.
Further, flexible slot is annular groove.
Further, flexible slot is annular groove.
Further, flexible slot includes circumferentially disposed multiple grooves section along bent axle.
Further, the depth of flexible slot is less than length of the bearing arrangement along bent axle axial direction.
Further, the depth of flexible slot is less than 1/2nd of length of the bearing arrangement along bent axle axial direction.
The invention has the advantages that：
Flexible slot is set on lower cover, stress concentration is reduced, the elastic deformation between bent axle and bearing arrangement is improved
Amount, the contact stress between reduction bent axle and bearing is concentrated, and is reduced impulsive force, so as to reduce noise peak, is eventually reduced and make an uproar
The overall decibel value of sound.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.
Below with reference to figure, the present invention is further detailed explanation.
Brief description of the drawings
The accompanying drawing for constituting the part of the application is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its illustrate to be used to explain the present invention, do not constitute inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is the internal sectional schematic diagram of the compressor according to the present invention；And
Fig. 2 is the schematic cross-sectional view of the lower cover of the compressor according to the present invention.
Reference in accompanying drawing is as follows：1st, lower cover；2nd, lower flange；3rd, lower cylinder；4th, lower roller；5th, pump partition plate；
6th, bent axle；7th, upper cylinder；8th, upper roller；9th, upper flange；10th, flexible slot.
Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
Referring to Fig. 1 and Fig. 2, according to the compressor of the present invention, including：Bent axle 6；Upper flange 9, is set on bent axle 6；Lower cover
Plate 1, is set on bent axle 6, and flexible slot 10 is provided with lower cover 1.Flexible slot is set on lower cover, stress collection is reduced
In, the elastic deformation amount between bent axle and bearing arrangement is improved, the contact stress between reduction bent axle and bearing is concentrated, reduction punching
Power is hit, so as to reduce noise peak, the overall decibel value of noise is eventually reduced.
Compressor also includes bearing arrangement, and bearing arrangement is arranged on lower cover 1.Flexible slot 10 be arranged on lower cover 1 with
On the thrust surface contact jaw of bent axle 6.
Compressor also includes the lower flange being set on bent axle 6, and lower flange is set between upper flange 9 and lower cover 1, under
The hardness of cover plate 1 is more than the hardness of lower flange.Lower cover 1 is cast-iron structure, and lower flange is powder metallurgy structure.And use axle
Bearing structure, which is placed on lower cover, can just solve the above problems, and lower flange uses powdered metallurgical material first, without casting
Burr, overlap, using the skirt border structure for not having to tilt on the lower cover excircle of cast iron materials, can use engine lathe turning casting
Material surface, turning cost is more much lower than the milling of numer centre, and speed of production is fast, thus both reduced production cost or
Processing efficiency is improved, is occurred while avoiding drop burr, the integrity problem of overlap and stuck compressor of casting material.
Flexible slot is opened up on bearing can just reduce noise and vibration, but powdered metallurgical material strength ratio cast iron materials
Low, the intensity of bearing must be ensured using cast iron materials by opening up the bearing of flexible slot, so setting bearing just must on lower cover
Cast iron materials must be used；Because bearing is on lower cover, so aligning has reformed into the adjustment to lower cover and lower cylinder, and spiral shell
Nail is also directly to be pressed on lower cover, is avoided after bearing and cylinder aligning, upper and lower cylinder screw hole during the conjunction heart of appearance
Bias, causes the problem of screw screws difficulty to occur, it is to avoid therefore the stuck problem of the caused pump housing, so as to improve efficiency of assembling.
Referring to Fig. 1 and Fig. 2, flexible slot 10 is circumferentially disposed along bent axle 6.Flexible slot 10 is annular groove.Preferably, flexible slot 10
For annular groove.For proof strength, flexible slot 10 can include circumferentially disposed multiple grooves section along bent axle 6.
In order to ensure enough intensity, the depth of flexible slot 10 is less than length of the bearing arrangement along the axial direction of bent axle 6, preferably
/ 2nd of length no more than bearing arrangement along the axial direction of bent axle 6.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：
Flexible slot is set on lower cover, stress concentration is reduced, the elastic deformation between bent axle and bearing arrangement is improved
Amount, the contact stress between reduction bent axle and bearing is concentrated, and is reduced impulsive force, so as to reduce noise peak, is eventually reduced and make an uproar
The overall decibel value of sound.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
