Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figures 1 to 3, according to the pump housing of the present invention, including cylinder body 10, it is rotatably arranged in
Turning cylinder 20 within cylinder body 10, and drive the rotor 30 turning cylinder 20 motion, the pump housing also includes many
Individual rolling element 40, multiple rolling elements 40 are circumferentially uniformly arranged on and turn between cylinder 20 and cylinder body 10.
The present invention, by being uniformly arranged multiple rolling element 40 turning to arrange between cylinder 20 and cylinder body 10, compares existing
There is technology, make the sliding friction turning between cylinder 20 outer wall and cylinder body 10 inwall by rolling element 40 turns
Become rolling friction, reduce coefficient of friction, it is possible to efficiently reduce abrasion, improve the life-span, simultaneously by
Reduce in coefficient of friction, it is also possible to improve efficiency.It addition, arrange rolling element 40, need to take the pump housing
Radial space so that reducing the radial distance of friction pair and axle center in the pump housing, thus reduce and rub
Wipe secondary linear velocity, be greatly reduced power consumption.
Further, the pump housing also includes retainer, and retainer is arranged on and turns between cylinder 20 and cylinder body 10,
Free to rotate being arranged on retainer of multiple rolling elements 40, by arranging retainer, can make
Between multiple rolling elements 40, position keeps relative stability, and improves reliability.It addition, in order to keep
Rolling element is stable, and cylinder body 10 inwall offers the groove matched with rolling element 40, and rolling element is by protecting
Hold the most stable rotation of frame and revolution motion and do not fall off；Correspondingly, cylinder 20 outer wall is turned also
The groove matched with rolling element 40 can be offered, so that turning cylinder 20 energy and rolling element when motion
40 coordinate and do not fall off.
Preferably, retainer is fixedly installed on the inwall of cylinder body 10, so that rolling element 40 is turning
Position between cylinder 20 and cylinder body 10 is more stable.As required and space arrange, rolling element 40 can
To be set to one layer, it is also possible to be set to more than two-layer, when being set to more than two-layer, it is possible to more enter one
Step ground reduces coefficient of friction.
In the first embodiment of the present invention, shown in Fig. 1 and Fig. 3, the pump housing also includes slide plate 50,
Being provided with the vane slot 60 coordinated with slide plate 50 on rotor 30, slide plate 50 includes that at least one is hinged
Slide plate 51；First end of each pinned vane 51 is telescopically disposed in vane slot 60, hinged cunning
Second end of sheet 51 is with to turn cylinder 20 hinged.
Specifically, turn and on cylinder 20, offer hinged groove 21, pinned vane 51 by hinged groove 21 with
Turning cylinder 20 to coordinate, hinged groove 21 opening subtended angle is set as certain angle, to avoid pinned vane 51
Interfere with hinged groove 21 edge when motion, by coordinating of pinned vane 51 and hinged groove 21,
It is delivered to turn cylinder 20 by the power on main shaft (rotor 30), turns outer wall and rolling element when cylinder 20 moves
40 contacts and not with cylinder body 10 contact internal walls, rolling element 40 rotates with turning cylinder 20, thus will
Sliding friction becomes rolling friction.
Pinned vane 51 quantity can be single, it is achieved single articulated manner, it is also possible to be multiple, real
Much the most hinged or full articulation mode.It addition, pinned vane 51 can also seal with one or more
Slide plate 52 with the use of.I.e. slide plate 50 can also arrange one or more and seal slide plate 52, seals
First end of slide plate 52 is telescopically disposed in vane slot 60, seal slide plate 52 the second end with
The inwall slipper seal turning cylinder 20 coordinates.
When using single hinged or many articulated manner, seal the head (the second end) of slide plate 52 and turn
The gap of cylinder 20 is maintained between 0.01mm～0.015mm, can be come by the refrigeration oil in compression chamber
Ensure its sealing, will not leak, it is achieved slipper seal coordinates.In figure 3, slide plate 50
Use two modes sealing slide plate 52 and pinned vane 51 cooperation.
When using full articulation mode, when the most all slide plates 50 are pinned vane 51, seal reliable,
Will not leak.Head can be reduced additionally, pinned vane 51 compares sealing slide plate 52 and turn cylinder 20
Relative velocity, reduce friction power loss further.
Shown in Fig. 1, the pump housing includes upper flange 70 and the purgation being arranged on the axial two ends of cylinder body 10
Blue 80, usually, turn the difference in height that cylinder 20 and cylinder body 10 exist monolateral 0.008～0.012mm,
Thus ensure upper flange 70 and lower flange 80 screw turn after tightening cylinder 20 can also flexible rotating and not by
Flange screw is stuck, and this gap can ensure its sealing, phase by the refrigeration oil in compression chamber simultaneously
Ying Di, the two ends of multiple rolling elements 40 and upper flange 70 and lower flange 80 matched in clearance, thus anti-
Only flange is by stuck for rolling element 40.
In the first embodiment, for vane slot 60 is arranged on rotor 30, such that it is able to realize
Rotor quality without acceptance of persons, it is not required that the inlet channel of complexity is set on rotor, so that structure is more
Simply.
In the second embodiment of the present invention, vane slot 60 can also be arranged on and turn on cylinder 20, the most sliding
First end of sheet 50 is fixedly installed on rotor 30, and the second end of slide plate 50 can be slided along vane slot 60
It is arranged in vane slot 60 dynamicly, thus turns cylinder 20 by rotor 30 drive and rotate, form compression
Process.
Present invention also offers one and turn cylinder compressor, including driving means and and the aforesaid pump housing, drive
Dynamic device drives the rotor 30 of the pump housing to rotate.Use the aforesaid pump housing such that it is able to be effectively reduced
Cylinder body 10 and the friction system turned between cylinder 20, reduce friction and power consumption, improves life-span and efficiency.
As can be seen from the above description, the above embodiments of the present invention achieve following technology effect
Really:
The pump housing according to the present invention and turn cylinder compressor, by uniformly setting turning to arrange between cylinder and cylinder body
Put multiple rolling element, compared to existing technology, make the sliding friction turning between cylinder outer wall and inboard wall of cylinder block lead to
