There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention, for those of ordinary skill in the art, without creative efforts, can be with
Other attached drawings are obtained according to these attached drawings.
The structure diagram for the cylinder assembly that Fig. 1 is provided for a kind of specific embodiment of the present invention；
Fig. 2 is the lateral partial structurtes sectional view of sliding vane groove and side opening part in Fig. 1；
Fig. 3 is the force analysis figure of Fig. 1.
Specific embodiment
The core of the present invention is to provide a kind of cylinder assembly, and the modular construction of the cylinder assembly is not susceptible to inordinate wear,
And compressor overall structure reliability can be improved；Meanwhile provide a kind of compressor using above-mentioned cylinder assembly.
In order to which those skilled in the art is made to more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
It please refers to Fig.1 and the structural representation of cylinder assembly that Fig. 2, Fig. 1 are provided for a kind of specific embodiment of the present invention
Figure；Fig. 2 is the lateral partial structurtes sectional view of sliding vane groove and side opening part in Fig. 1.
In a specific embodiment, cylinder assembly provided by the present invention, including cylinder body 11,11 middle part of cylinder body
With inner cavity 111, roller 12 is provided in inner cavity 111, sliding vane groove 112, sliding vane groove are radially provided on cylinder body 11
Slide plate 13 is movably disposed in 112, the inner end of slide plate 13 stretches out in internal chamber wall and is engaged with 12 outer circumferential surface of roller,
The host buffer part 14 being adapted with the outer end of slide plate 13 is additionally provided on cylinder body 11；The side of sliding vane groove 112 has side
Hole 113 is fitted with bayonet lock 15 in side opening 113, and bayonet lock 15 is provided with what is be engaged with slide plate 13 at one end close to slide plate 13
Ball 16, bayonet lock 15 are provided with secondary bolster 17 at one end away from slide plate 13.
In the course of work, ball 16 in side opening 113 is in secondary bolster 17 and 15 combined mechanism of bayonet lock and related
It is in contact always with slide plate 13 under the action of draught head in slotted hole structure, so as to effectively reduce between slide plate 13 and sliding vane groove 112
Contact force, and then reduce the structural friction force between slide plate 13 and sliding vane groove 112, the abrasion of slide plate 13 and its dependency structure is reduced,
It reduces compressor power consumption and improves compressor operating Performance And Reliability.
It should be pointed out that although high-pressure side position may change under specific working condition, above-mentioned side opening 113 and
Its internal bayonet lock 15 and 16 grade modular constructions of ball are specifically arranged at the high-pressure side of cylinder body 11 in principle, to ensure to slide
The stress balance and stable structure of piece 13.
It please refers to Fig.3, Fig. 3 is the force analysis figure of Fig. 1.
Further, the spacing of ball 16 and internal chamber wall is the 1.55~2.65 of the length that slide plate 13 stretches out in internal chamber wall
Times.For ease of understanding, to 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 are as follows：
F1*L1=F2*L2 ... ... ... is 1.
F1+F2=F ... ... ... is 2.
Wherein, L1 --- slide plate 13 stretches out in the length of internal chamber wall
The spacing of L2 --- ball 16 and internal chamber wall
During compressor operating, operating mode determines (i.e. high-low pressure is certain), and F1 is fixed value, to reduce slide plate and cylinder
2. contact stress F is understood to need to reduce slide plate afterbody and cylinder contact power F2 by relational expression.It 1. being understood according to relational expression, L2 is bigger,
F2 is smaller.
According to more than force analysis, the position of ball 16 is better closer to the outer end of sliding vane groove 112, i.e. ball 16
Be the bigger the better with the spacing L2 of internal chamber wall, while to ensure to contact with ball 16 when slide plate 13 stretches out most long, if therefore L2 it is too big,
Slide plate 13 can be caused too long, determine to ensure that L2=1.55~2.65L1 is preferable after comprehensive analysis.Certainly, which closes
System is only the preferred value that the application needs selection according to actual condition, and staff can change according to operating mode in practical operation
The proportionate relationship between above-mentioned dimensional parameters is adjusted flexibly, but should ensure that the normal table of cylinder assembly runs and meets pressure in principle
The actual use of contracting machine needs.
It will be appreciated that specific to practical set in use, the cross section of above-mentioned side opening 113 is preferably to be adapted with ball 16
Circle, can also be the planform that can be adapted with ball 16 such as square or oval, i.e. as long as disclosure satisfy that institute
Stating the actual use of cylinder assembly needs.
More specifically, side opening 113 is two, two side holes 113 are respectively positioned on the same side of sliding vane groove 112, and between two side holes 113
It is parallel.This kind of double-pore structure can form double roll structures and implement uniform reliable active force to slide plate 13, ensure slide plate 13
Overall co-ordination structure it is reliable and stable, and further avoid its generate structural wear.
It certainly, also should be according to described previously, by two side holes 113 even if using 113 parallel fit structure of above-mentioned two side opening
The high-pressure side of cylinder body 11 is may be contained within, needs are run to meet actual cylinder assembly.
On the other hand, host buffer part 14 and secondary bolster 17 are spring.The simple and reliable for structure and use of this kind of spring
Cost is relatively low, can suitably reduce its production cost while cylinder assembly structural behaviour is ensured.Certainly, 14 He of host buffer part
Secondary bolster 17 is not limited to spring shown in figure, can also be the resilient snubber of rubber or plastic cement material, i.e. as long as
It is that disclosure satisfy that the actual use of the cylinder assembly needs.
In addition, ball 16 is steel ball.The structural strength of steel ball is high, and wear-resistant and shock resistance is good, can be further
Improve the integral working of cylinder assembly.
In a specific embodiment, it is total to be provided with cylinder including body, on the body for compressor provided by the present invention
Into the cylinder assembly is specially the cylinder assembly as described in each embodiment above.The overall structure reliability of the compressor
It is higher, and the modular construction of its cylinder assembly is not susceptible to inordinate wear.
In summary, the cylinder assembly provided in the present invention has interior including cylinder body, in the middle part of the cylinder body
Chamber, the interior intracavitary are provided with roller, and sliding vane groove is radially provided on the cylinder body, is moved in the sliding vane groove
Ground is provided with slide plate, and the inner end of the slide plate stretches out in the internal chamber wall and is engaged with the roller outer circumferential surface, described
The host buffer part being adapted with the outer end of the slide plate is additionally provided on cylinder body；The side of the sliding vane groove has side
Hole is fitted with bayonet lock in the side opening, and the bayonet lock close to the slide plate is provided with and is engaged with the slide plate at one end
