And operational reliability.
The invention reside in the rectangle oil groove by opening up certain area in slide plate side (high-pressure side) afterbody ad-hoc location, and
Open up oil inlet passage；Opening up annular oil guide groove in end face of flange special angle scope, (opening up position needs the work according to compressor
Condition is formulated).
(slide plate is by near the maximum position of both sides difference force), slide plate afterbody when compressor pump rotates to special angle
Oil inlet passage can be connected with the oil guide groove held successfully in advance in flange correspondence position so that the hydraulic oil inside flange oil guide groove leads to
Cross oil inlet passage and flow into vane slot side oil groove, it is possible thereby to the power perpendicular to slide plate be formed in slide plate high-pressure side afterbody, with flat
Weighing apparatus slide plate front end by both sides high-low pressure chamber because being existed and the bias force that produces so that slide plate avoid because of biasing with the vane slot degree of lip-rounding
Inordinate wear is produced into linear contact lay, the life-span of slide plate is improved to a certain extent, while reducing friction power loss herein.
Slide plate high-pressure side afterbody opens up certain area and the rectangular channel of depth, and opens up oil inlet passage, such as Fig. 1 in groove lower end
It is shown；Simultaneously for the rotational characteristics of slide plate machine, open up oriented main shaft vane slot in lower flange end face and extreme pressure lubricant is provided
Annular flange back pressure groove, and the certain angle opened up in relevant position arc oil groove, as shown in Figure 6；In the lower end of main shaft
Axial main shaft oilhole is provided with, and main shaft radial direction oil hole is offered in the both sides of central part, in order to which lubricating oil is from main shaft oilhole
Lower flange back pressure groove is flowed out into main shaft, and via main shaft radial direction oil hole, back pressure is provided for the slide plate in main shaft vane slot, is had
Body is as shown in Figure 3；
And slide plate and the cooperation of the structure of lower flange two are mainly：Slide plate is moved in vane slot with main axis, works as cunning
When piece turns to special angle (this angle need to be formulated according to actual condition), slide plate head is because slide plate two sides high pressure chest and low
Press the effect of the difference force and head frictional force of chamber so that the biasing to low-pressure side direction occurs in slide plate head.And it is same with this
When connected with the arc oil groove of lower flange end face because of the presence of said structure, the oil inlet passage of slide plate bottom so that arc oil groove
Refrigeration oil enter the rectangle oil groove of slide plate side, and freezing oil pressure herein is close to pressure at expulsion (high pressure), and opposite side
It is the mesolow power produced by the presence in gap, refers to so that the slide plate under this angle is produced in afterbody perpendicular to slide plate
To the pressure of low-pressure side so that the equalising torque of slide plate end to end, specific polar plot can as shown in Figure 8, and p points are stress maximum point
Locate, that is to say the point that slide plate is rotated with the point, F1 is pressure differential between cylinder chamber mesohigh chamber and low pressure chamber, and M1 is the pressure
The torque that difference is formed, F2 improves the high pressure oil pressure produced by set side oil groove for the present invention, and M2 is produced by the oil pressure
Raw torque, so as to balance torque M1 so that linear contact lay originally is changed into face contact, o points are that the rotating shaft center of circle, arrow are its turn
Dynamic direction, so that slide plate presses close to vane slot and so avoids the abnormal mill that slide plate is produced by biasing with vane slot tip
Damage, it is specific as shown in Figure 4.
And the hydraulic oil of lower flange arc oil groove from main shaft when turning to special angle (this angle with it is above-mentioned specific
Angle is identical), flange back pressure groove is connected with flange deep-slotted chip breaker by main shaft vane slot so that the hydraulic oil of flange back pressure groove passes through
Main shaft vane slot enters arc oil groove, and then provides hydraulic oil for the rectangle oil groove of slide plate side.It is specific as shown in Figure 6.
Because bias force suffered by the maximum fragment position slide plate head of slide plate extension elongation is away from maximum, it is necessary to which afterbody is put down
Weighing apparatus, remaining position are because be not in this problem substantially the problem of extension elongation and operating mode, so lower flange oil groove is opened
If only one section radian, after slide plate rotates through this section of angle, bottom oil inlet passage disconnects with lower flange end face, so that sliding
The stress of piece returns normal.
Main oil circuit：Main shaft oilhole-main shaft radial hole-lower flange back pressure groove-main shaft vane slot-lower flange arc
Groove-oil groove passage (slide plate side)-slide plate side oil groove, overall oil circuit can be checked by Fig. 3 explosive views.
Flange back pressure groove and arc oil groove can also be opened simultaneously in the end face relative position of upper flange, slide plate is carried simultaneously
For above-mentioned oil pressure！Can be with the highly efficient slide plate inordinate wear for solving the problems, such as slide plate machine.Shown in specific visible Fig. 2 and Fig. 7.
The shape of slide plate side oil groove is not necessarily rectangle, can also be formulated according to actual loading situation；
Those skilled in the art is it is easily understood that on the premise of not conflicting, above-mentioned each advantageous manner can be free
Ground combination, superposition.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.With
Only it is the preferred embodiment of the present invention described in upper, it is noted that for those skilled in the art, not
On the premise of departing from the technology of the present invention principle, some improvement and modification can also be made, these improvement and modification also should be regarded as this
The protection domain of invention.
