The implication that the technical staff in domain is generally understood that is identical.In term used in the description of the present utility model it is simply herein
The purpose of description specific embodiment is it is not intended that in limiting this utility model.Term as used herein "and/or" includes
The arbitrary and all of combination of one or more related Listed Items.
With reference to Fig. 1, this utility model provides the rotary compressor of an embodiment, including electric machine assembly and rotary pressure
Contracting machine pump assembly 100.Rotary type compressor pump body provided therewith assembly 100 include cylinder 110, rolling member 120, rotor 130, slide plate 140,
Elastic component 150, bent axle 160, flange 170 and deafener 180.
Rotor 130 is sheathed on bent axle 160, and rotor 130 can rotate relative to bent axle 160.Flange 170 is located at cylinder 110
Both sides in axial direction, play sealing and protective effect to cylinder 110.Deafener 180 is used for electric machine assembly and rotary compression
Machine pump assembly 100 abates the noise.
With reference to Fig. 2, in cylinder 110, set cylinder chamber 111, the cavity wall circumference of cylinder chamber 111 be provided with respectively with cylinder chamber 111
The air entry 112 of connection, air vent 113 and vane slot 114.Air entry 112 and air vent 113 are respectively close to vane slot 114
Both sides and set.Rotor 130 is located in cylinder chamber 111 and can rotate along its cavity wall in cylinder chamber 111.The drive shaft of electric machine assembly
It is connected with bent axle 160, thus driving bent axle 160 rotor driven 130 to rotate along its cavity wall in cylinder chamber 111.
Specifically, in the present embodiment, the quantity of rolling member 120 is two.Specifically, two rolling members 120 respectively can
Two cell walls relatively being connected to vane slot 114 rotating, rolling member 120 is at least partially disposed in vane slot 114.Specifically, exist
In the present embodiment, rolling member 120 is roller bearing, and rolling member 120 can rotate along its pivot center (not shown), the axle of rolling member 120
Arrange in the same direction to the axial direction with cylinder 110.
It is appreciated that rolling member 120 is alternatively ball, ball can around fixing pivot axis as roller bearing,
Can be without the pivot center of fixation, as long as its own rotates.It is appreciated that the quantity of rolling member 120 is not limited to two,
Can be three or more than three.
Slide plate 140 and can move along the length direction of vane slot 114 between two rolling members 120.Slide plate 140 and two
Individual rolling member 120 rolls connection respectively, and slide plate 140 is close to the lateral wall of rotor 130 in the rotation process of rotor 130.
Specifically, slide plate 140 is connected with elastic component 150 away from the end of rotor 130, so that slide plate 140 is in the work of elastic component 150
It is close to the lower lateral wall with rotor 130.
So slide plate 140 moves along the length direction of vane slot 114, drives rolling member 120 to rotate, slide plate 140 and slide plate
It is rolling friction between rolling member in groove 114, change the structure that original slide plate 140 slides in vane slot 114, significantly subtract
The frictional dissipation that little slide plate 140 is subject to, improves service life and the reliability of slide plate 140, reduces power attenuation, improves
Compression efficiency.
With reference to Fig. 3 and Fig. 4, more specifically, two cell walls relatively of vane slot 114 are distributed in the week of the cavity wall of cylinder chamber 111
Upwards., closer to air entry 112, another cell wall is closer to air vent 113 for one of cell wall.
Two rolling members 120 are respectively connected to the first rolling member 121 of the cell wall closer to air entry 112 and are connected to
The second rolling member 122 closer to the cell wall of air vent 113.Specifically, the first rolling member 121 compares the second rolling member 122 more
Near cylinder chamber 111.So cylinder chamber 111 is divided into compression chamber and suction muffler, and the gas of compression chamber by slide plate 140 and rotor 130
When body pressure is more than the gas pressure of suction muffler, therefore slide plate 140 can in the presence of pressure at both sides difference towards gas pressure relatively
The lopsidedness of little suction muffler, the first rolling member 121 is arranged on the cell wall of vane slot 114 near the side of air entry 112, and
Near one end of cylinder chamber 111 in vane slot 114, thus supporting role can be had to the slide plate 140 that will tilt, prevent
The inclination of slide plate 140, it is to avoid slide plate 140 and rotor 130 depart from the problem leading to gas blowby between suction muffler and compression chamber.
With continued reference to Fig. 3, specifically, in the present embodiment, two cell walls relatively of vane slot 114 are respectively equipped with and vane slot
The mounting groove 115 of 114 connections.First rolling member 121 and the second rolling member 122 are respectively arranged in mounting groove 115.And first rolling
Moving part 121 and the second rolling member 122 are all partly exposed to the cell wall of mounting groove 115, so that rolling member 120 part is located at slide plate
In groove 114.Rolling member 120 is installed in mounting groove thus being indirectly coupled to the cell wall of vane slot 114.It is appreciated that two rollings
Moving part 120 may be also connected directly to the cell wall of vane slot 114.It is appreciated that in other embodiments, rolling member 120 also can be complete
Entirely it is located in vane slot 114, as long as rolling member 120 is at least partially disposed in vane slot 114.
Preferably, the size that rolling member 120 is diametrically exposed to the cell wall of mounting groove 115 is 0.005～0.0075mm.
In view of the sealing of rolling member 120 and slide plate 140 two side clearances in vane slot 114, the diameter of rolling member 120 more little more
Good；It is contemplated that the supporting role to slide plate 140 for the rolling member 120, the too little support insufficient strength of diameter of rolling member 120, and
And diameter is too small, it is unfavorable for that rolling member 120 is processed and assembled.Summary performance considers, the diameter of rolling member 120 is not preferably little
In 3mm.
More specifically, from opening to bottom land for diminishing structure, and mounting groove 115 is right for the cell wall of mounting groove 115
Rolling member 120 carries out spacing.Miscellaneous part is not so needed to coordinate, as long as rolling member 120 is limited in mounting groove 115, then
By slide plate 140 between this two rolling members 120, and its opposite sides is supported with two rolling members 120 respectively.Slide plate
140 drive rolling member 120 to rotate when moving along the length direction of vane slot 114.
More specifically, in the present embodiment, the bottom land of mounting groove 115 is V-type, and mounting groove 115 is in two cell walls of opening
It is arranged in parallel.By spacing for rolling member 120 in mounting groove 115, two walls parallel settings of opening facilitate rolling member at V-groove bottom
120 enter mounting groove 115 to be installed.It is appreciated that mounting groove 115 is alternatively the cambered surface knot being adapted with rolling member 120
Structure.
Each technical characteristic of embodiment described above can arbitrarily be combined, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic applied in example is all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope of this specification record.
Embodiment described above only have expressed several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, some deformation can also be made and improve, these broadly fall into
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
