Detailed description of the invention
Core of the present utility model is to provide a kind of cylinder assembly, the modular construction of this cylinder assembly
It is not susceptible to inordinate wear, and compressor overall structure reliability can be improved；Simultaneously, it is provided that
A kind of compressor applying above-mentioned cylinder assembly.
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with
The utility model is described in further detail for the drawings and specific embodiments.
Refer to Fig. 1 and Fig. 2, Fig. 1 provided by this utility model one detailed description of the invention
The structural representation of cylinder assembly；Fig. 2 is the local knot of vane slot and side opening part in Fig. 1
Structure sectional view.
In a specific embodiment, cylinder assembly provided by the utility model, including cylinder originally
Body 11, has inner chamber 111, is provided with roller 12 in inner chamber 111 in the middle part of cylinder body 11,
Radially it is provided with vane slot 112 on cylinder body 11, sets movably in vane slot 112
Being equipped with slide plate 13, the inner end of slide plate 13 stretches out in internal chamber wall and contacts with roller 12 outer peripheral face
Coordinate, cylinder body 11 is additionally provided with the host buffer part suitable with the outer end of slide plate 13
14；The sidepiece of vane slot 112 has side opening 113, is fitted with bayonet lock 15 in side opening 113, card
Pin 15 is at one end provided with near slide plate 13 and contacts the ball 16 coordinated with slide plate 13, card
Pin 15 is at one end provided with secondary bolster 17 away from slide plate 13.
In work process, it is positioned at the ball 16 of side opening 113 at secondary bolster 17 and bayonet lock 15
All the time contact with slide plate 13 under the effect of combined mechanism and associated groove pore structure internal gas pressure difference,
Thus effectively reduce the contact force between slide plate 13 and vane slot 112, and then reduce slide plate 13 with
Structural friction force between vane slot 112, reduces slide plate 13 and the abrasion of dependency structure thereof, reduces
Compressor power consumption also improves compressor operating Performance And Reliability.
Should be understood that, although position, high-pressure side under concrete working condition it may happen that change,
But above-mentioned side opening 113 and the internal modular construction such as bayonet lock 15 and ball 16 thereof the most all have
Body is arranged at the high-pressure side of cylinder body 11, steady with the stress balance and structure ensureing slide plate 13
Fixed.
Refer to the force analysis figure that Fig. 3, Fig. 3 are Fig. 1.
Further, ball 16 is the length that slide plate 13 stretches out in internal chamber wall with the spacing of internal chamber wall
1.55～2.65 times of degree.For ease of understanding, make force analysis in conjunction with Fig. 3 as follows:
Slide plate is lateral stressed: high-low pressure difference force F1, slide plate and cylinder contact stress F, slide plate
Tail end and cylinder contact power F2, stress relation is as follows:
F1*L1=F2*L2 ... ... ... 1.
F1+F2=F ... ... ... 2.
Wherein, L1 slide plate 13 stretches out in the length of internal chamber wall
L2 ball 16 and the spacing of internal chamber wall
During compressor operating, operating mode determines (i.e. high-low pressure is certain), and F1 is fixed value,
For reducing slide plate and cylinder contact stress F, relational expression 2. understand and need to reduce slide plate afterbody and gas
Cylinder contact force F2.1. understanding according to relational expression, L2 is the biggest, and F2 is the least.
According to above force analysis, the position of ball 16 is the closer to the outer end of vane slot 112
The best, i.e. ball 16 is the bigger the better with spacing L2 of internal chamber wall, slide plate 13 to be ensured
Contact with ball 16 when stretching out the longest, if therefore L2 is too big, slide plate 13 can be caused oversize,
After comprehensive analysis, determine that guarantee L2=1.55～2.65L1 is preferable.Certainly, this size multiple
Relation is only the preferred value that the application needs to select according to actual condition, works in practical operation
Personnel can be adjusted flexibly the proportionate relationship between above-mentioned dimensional parameters according to working conditions change, but principle
On should ensure that the normal table of cylinder assembly runs and meets the actually used needs of compressor.
During it will be appreciated that use specific to practical set, the cross section of above-mentioned side opening 113 is preferred
For the circle suitable with ball 16, it is also possible to for square or oval etc. can be with ball 16
Suitable planform, i.e. as long as disclosure satisfy that the actually used need of described cylinder assembly
Will.
More specifically, side opening 113 is two, two side holes 113 is respectively positioned on the same of vane slot 112
Between side, and two side holes 113 parallel.This kind of double-pore structure can form double roll structure pair
Slide plate 13 implements active force the most reliably, it is ensured that stably may be used of slide plate 13 overall co-ordination structure
Lean on, and avoid it to produce structural wear further.
Certainly, even if using the parallel fit structure of above-mentioned two side opening 113, also should be according to above
Described, two side holes 113 be may be contained within the high-pressure side of cylinder body 11, with the gas of satisfied reality
Cylinder assembly runs to be needed.
On the other hand, host buffer part 14 and secondary bolster 17 are spring.The knot of this kind of spring
Structure is simple and reliable and use cost is relatively low, it is possible to suitable while ensureing cylinder assembly structural behaviour
When reducing its production cost.Certainly, host buffer part 14 and secondary bolster 17 are not limited to figure
Shown in spring, it is also possible to for rubber or the resilient snubber of plastic cement material, i.e. as long as
Disclosure satisfy that the actually used needs of described cylinder assembly.
It addition, ball 16 is steel ball.The structural strength of steel ball is high, and wear-resistant and shock resistance
Performance is good, it is possible to improve the integral working of cylinder assembly further.
In a specific embodiment, compressor provided by the utility model, including body, institute
Stating and be provided with cylinder assembly on body, described cylinder assembly is specially as described in the most each embodiment
Cylinder assembly.The overall structure reliability of described compressor is higher, and the group of its cylinder assembly
Part structure is not susceptible to inordinate wear.
In summary, the cylinder assembly provided in this utility model, including cylinder body, described
Having inner chamber in the middle part of cylinder body, described interior intracavity is provided with roller, edge on described cylinder body
It has been radially arranged vane slot, is movably disposed within slide plate, described slide plate in described vane slot
Inner end stretch out in described internal chamber wall and contact cooperation, described cylinder with described roller outer peripheral face
The host buffer part suitable with the outer end of described slide plate it is additionally provided with on body；Described vane slot
Sidepiece there is side opening, be fitted with bayonet lock in described side opening, described bayonet lock is near described slide plate institute
At one end being provided with and contact the ball coordinated with described slide plate, described bayonet lock is away from described slide plate institute
At one end it is provided with secondary bolster.In work process, it is positioned at the ball of side opening at secondary bolster
All the time connect with slide plate under the effect poor with bayonet lock combined mechanism and associated groove pore structure internal gas pressure
Touch, thus effectively reduce the contact force between slide plate and vane slot, and then reduce slide plate and vane slot
Between structural friction force, reduce slide plate and the abrasion of dependency structure thereof, reduce compressor power consumption also
Improve compressor operating Performance And Reliability.
Additionally, the compressor of the above-mentioned cylinder assembly of application provided by the utility model, it is overall
