Abstract
The invention discloses a rotating stator type double-acting variable vane pump. A rotor (10) and a stator (2) of the pump are clamped between flow distribution side plates (12). A front flow distribution cover (5) and a rear flow distribution cover (13) are arranged outside the flow distribution side plates (12) respectively. A pump shaft (11) is positioned through a rolling bearing (8). A front pump cover (6) is fixedly connected with a rear pump cover (1) through a connecting bolt (14). The central position of the stator (2) is determined by four positioning screws (15) with sleeves, and the positioning screws (15) with the sleeves are circumferentially and uniformly arranged and connected to the front flow distribution cover (5) and the rear flow distribution cover (13). A rotating rod (18) on the stator (2) is fixed by a variable bolt (19) and a compression spring (17). When the bolt (19) rotates, the rotating rod (18) drives the stator (2) to rotate under the action of the compression spring (17), thereby realizing a variable of the pump. A variable mechanism is sealed through a variable mechanism cover (20).

Fig. 1 is double-acting vane pump working principle schematic representation, and Fig. 2 is rotatable stator formula double-function variable vane pump structural drawing, and Fig. 3 is the side cutaway view of Fig. 2, and reference character and name are called: rear pump cover 1, stator 2, female blade 3, blades 4, preceding flow lid 5, the preceding pump housing 6, flat key 7, rolling bearing 8, pin 9, rotor 10, pump shaft 11, flow side plate 12, back flow lid 13, connecting bolt 14, positioning screwn 15, screw 16, compression spring 17, dwang 18, variable bolt 19, stroking mechanism lid 20.
Embodiment
Vane pump mainly is made up of stator, rotor, blade, flow side plate and pump shaft, and wherein the stator of double-acting vane pump is by 2 sections orthodromes, and 2 sections little circular arcs and 4 sections transition curves are formed.Usually the adjacent blades angle equals the corresponding angle of orthodrome, adjacent 2 blades and both sides flow side plate composition working oil chamber, and in the orthodrome district, fluid volume maximum.When the last blade movement of this active chamber arrived the transition curve, blade inwardly shrank, and active chamber fluid volume is compressed, and when the gain of offering on active chamber and the flow side plate was connected, vane pump began oil extraction.
Fig. 1 is the working principle schematic representation of double-acting vane pump, and the corresponding cornerite in big or small circular arc district is
, the cornerite of oil suction district and oil extraction district correspondence is
, the oil extraction gain is opened on the thrust plate.Blade 1 and 2 active chambers of forming, last blade movement is to the transition curve, back one blade moves at orthodrome, rotation along with rotor, this active chamber sealing fluid volume reduces gradually, after active chamber and the connection of oil extraction gain, realize oil extraction, its oil drain quantity size is relevant with oil extraction gain length on time in the transition curve district with active chamber, in when, between stator and the flow side plate relative movement taking place when, the relative position of transition curve and oil extraction gain changes, and causes the change of oil drain quantity, thereby realizes the function of variable.
As Fig. 2, shown in Figure 3, the present invention isA kind of rotatable stator formula double-function variable vane pump, the rotor 10 of pump and stator 2 are clipped between the flow side plate 12, flow lid 5 and back flow covered 13 before be equipped with respectively front and back, pump shaft 11 is by rolling bearing 8 location, rolling bearing 8 is installed in the front pump cover 6, and front pump cover 6 uses connecting bolt 14 to be connected and fixed with rear pump cover 1; Four positioning screwns 15 decisions that have sleeve that connect on preceding flow lid 5 and the back flow lid 13 are installed in the central position of stator 2 by circumference uniform distribution, the dwang 18 that is installed on the stator 2 is fixing by variable bolt 19 and compression spring 17, when variable bolt 19 screws out, dwang 18 is under the effect of compression spring 17, drive stator 2 rotations, stroking mechanism uses 20 sealings of stroking mechanism lid, and stroking mechanism lid 20 uses screw 16 to be fixed on the rear pump cover 1; Blades 4 is enclosed within female blade 3, be set in the blade groove of rotor 10, stator 2 is respectively by 2 sections orthodromes, 2 sections little circular arcs, 4 sections transition curves are formed, and rotor 10 rotates under the drive of pump shaft 11, and blade 3 is under the effect of rotor 10, do fore and aft motion in stator 2, the flow side plate 12 of blade and both sides forms the working oil chamber of sealing.Stroking mechanism uses 20 sealings of stroking mechanism lid, and stroking mechanism lid 20 uses screw 16 to be fixed on the rear pump cover (1).
When this pump needs variable, by being rotated counterclockwise variable bolt 19, promoting dwang 18 and move counterclockwise, do counterclockwise motion thereby drive stator 2, realize reducing of pump displacement; When needs increase pump delivery, be rotated counterclockwise variable bolt 19, thereby dwang 18 turns clockwise under the effect of compression spring 17, dwang 18 drives stator 2 simultaneously along the pointer rotation, realizes the increase of vane pump discharge capacity.
