Embodiment
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figures 1 to 3, according to the pump housing of the present utility model, comprise cylinder body 10, what be arranged on cylinder body 10 inside rotationally turns cylinder 20, and driving the rotor 30 turning cylinder 20 and move, the pump housing also comprises multiple rolling element 40, and multiple rolling element 40 is circumferentially evenly arranged on and turns between cylinder 20 and cylinder body 10.The utility model is by evenly arranging multiple rolling element 40 turning to arrange between cylinder 20 and cylinder body 10, compared to existing technology, the sliding friction turned between cylinder 20 outer wall and cylinder body 10 inwall is made to change rolling friction into by rolling element 40, reduce friction factor, can effectively reduce wear, improve the life-span, simultaneously because friction factor reduces, also can raise the efficiency.In addition, rolling element 40 is set, needs the radial space taking the pump housing, thus make the radial distance in friction pair and axle center in the reduction pump housing, thus reduce the linear velocity of friction pair, greatly reduce power consumption.
Further, the pump housing also comprises retainer, and retainer is arranged on and turns between cylinder 20 and cylinder body 10, what multiple rolling element 40 was free to rotate is arranged on retainer, by arranging retainer, position between multiple rolling element 40 can be made to keep relative stability, improving reliability.In addition, in order to keep rolling element to stablize, cylinder body 10 inwall offers the groove matched with rolling element 40, and rolling element is by the stable in a groove rotation of retainer and revolution motion and do not come off; Correspondingly, turn cylinder 20 outer wall and also can offer the groove matched with rolling element 40, thus make to turn cylinder 20 and can coordinate with rolling element 40 when moving and not come off.
Preferably, retainer is fixedly installed on the inwall of cylinder body 10, thus makes rolling element 40 to turn the position between cylinder 20 and cylinder body 10 more stable.As required and space arrange, rolling element 40 can be set to one deck, also can be set to two-layer more than, be set to two-layer above time, further can reduce friction factor.
In the first embodiment of the present utility model, shown in composition graphs 1 and Fig. 3, the pump housing also comprises slide plate 50, rotor 30 is provided with the vane slot 60 coordinated with slide plate 50, and slide plate 50 comprises at least one pinned vane 51; The first end telescopically of each pinned vane 51 is arranged in vane slot 60, and the second end of pinned vane 51 is with to turn cylinder 20 hinged.
Particularly, turn on cylinder 20 and offer hinged groove 21, pinned vane 51 by hinged groove 21 with turn cylinder 20 and coordinate, hinged groove 21 opening subtended angle is set as several angle, with avoid pinned vane 51 move time and hinged groove 21 edge interfere, by coordinating of pinned vane 51 and hinged groove 21, by the transmission of power on main shaft (rotor 30) to turning cylinder 20, turn outer wall when cylinder 20 moves contact with rolling element 40 and not with cylinder body 10 contact internal walls, rolling element 40 rotates with turning cylinder 20, thus sliding friction is become rolling friction.
Pinned vane 51 quantity can be single, realizes single articulated manner, also can be multiple, realizes how hinged or full articulation mode.In addition, pinned vane 51 can also and one or more sealing slide plate 52 with the use of.Namely slide plate 50 can also arrange one or more sealing slide plate 52, and the first end telescopically of sealing slide plate 52 is arranged in vane slot 60, and the second end of sealing slide plate 52 coordinates with the inwall slipper seal turning cylinder 20.
When adopting single hinged or many articulated manner, the head (the second end) sealing slide plate 52 and the gap turning cylinder 20 remain between 0.01mm ~ 0.015mm, its sealing can be ensured by the refrigeration oil in compression chamber, can not leak, realize slipper seal and coordinate.In figure 3, slide plate 50 adopts two modes sealing slide plate 52 and pinned vane 51 cooperation.
When adopting full articulation mode, when namely all slide plates 50 are pinned vane 51, sealing is reliable, can not leak.In addition, pinned vane 51 compares sealing slide plate 52 can reduce head and the relative velocity turning cylinder 20, reduces friction power loss further.
Shown in composition graphs 1, the pump housing comprises the upper flange 70 and lower flange 80 that are arranged on the axial two ends of cylinder body 10, usually, turn the height difference that cylinder 20 and cylinder body 10 exist monolateral 0.008 ~ 0.012mm, thus ensure to turn after upper flange 70 and lower flange 80 screw tighten cylinder 20 can also flexible rotating and not stuck by flange screw, this gap ensures its sealing by the refrigeration oil in compression chamber simultaneously, correspondingly, the two ends of multiple rolling element 40 and upper flange 70 and lower flange 80 Spielpassung, thus prevent flange by stuck for rolling element 40.
In a first embodiment, for vane slot 60 is arranged on rotor 30, thus rotor quality without acceptance of persons can be realized, also not need on rotor, arrange complicated gas-entered passageway, thus make structure simpler.
In the second embodiment of the present utility model, vane slot 60 also can be arranged on and turn on cylinder 20, namely the first end of slide plate 50 is fixedly installed on rotor 30, second end of slide plate 50 is slidably disposed in vane slot 60 along vane slot 60, thus driven by rotor 30 and turn cylinder 20 and rotate, form compression process.
The utility model additionally provides one and turns cylinder compressor, comprise drive unit and and the aforesaid pump housing, drive unit drives the rotor 30 of the pump housing to rotate.Adopt the aforesaid pump housing, thus the friction system that can effectively reduce cylinder body 10 and turn between cylinder 20, reduce friction and power consumption, improve life-span and efficiency.
