Embodiment
As shown in Figure 1 and Figure 2, electric machine casing 2 is provided with wiring terminal 1, at electric machine casing 2, motor stator 3 is installed, motor stator 3 is equipped with machine winding coil, there is rotor 15 motor stator 3 inside, be evenly equipped with multiple rotor bar in rotor 15, rotor center is inlaid with rotor inner sleeve 13, and rotor inner sleeve 13 is connected with the center rotor 7 of vane pump by the bolt on flange connecting plate 12; The blade pump housing comprises the outside oil suction pump housing 6, center rotor 7, the internal oil drainage pump housing 8 three part, the blade pump housing is in rotor inner sleeve 13, the outside oil suction pump housing 6 and the internal oil drainage pump housing 8 are bolted on motor front end cover 5, blade 16 is equipped with in center rotor 7 inside, and center rotor 7 relies on sliding bearing 11 on the inside and outside portion pump housing to support rotation; Motor front end cover has inlet port a and oil drain out b, between oil drain out b and motor front end cover 5 and electric machine casing 2 and motor front end cover 5, be provided with sealing 4 between rear end cover.
Rotor 15 and rotor inner sleeve 13 are fixed together by flat key 14, the left side of rotor inner sleeve 13 have bolt and flange connecting plate 12 fastening, equally, flange connecting plate 12 also has the left side of the center rotor 7 of bolt and vane pump fastening, back-up ring 10 is screwed on the internal oil drainage pump housing 8; The vane pump internal oil drainage pump housing 8 and the outside oil suction pump housing 6 rely on and are bolted on motor front end cover 5, and the center rotor 7 of the blade pump housing relies on sliding bearing 11 to form rotary support with the internal oil drainage pump housing 8 and the outside oil suction pump housing 6.
Outside oil scavenge pump body 6 has duct, and inlet port a communicates with machine cavity, oil inlet passage c, oil sucting cavity d; The internal oil drainage pump housing 8 has duct, and oil drain out b communicates with oil discharge passage f, oil-discharging cavity e.
Working procedure of the present utility model is as follows:
Fluid enters into the inside of electric machine casing 2 from inlet port a, flows with rotor 15, leads up to right-hand member gap to enter in the inner oil inlet passage c of rotor inner sleeve 13, and the window that flange connecting plate 12 is opened of separately leading up to enters oil inlet passage c from left end.Duct on the outside oil suction pump housing 6 makes inlet port a communicate with machine cavity, oil inlet passage c, oil sucting cavity d; Duct on the internal oil drainage pump housing 8 makes oil drain out b communicate with oil discharge passage f, oil-discharging cavity e.
When wiring terminal 1 switches on power to motor stator 3 winding coil in by terminal box, electromagnetic torque drive motor rotor assembly rotates, i.e. rotor 15, rotor inner sleeve 13, the center rotor 7 of flange connecting plate 12 and the blade pump housing rotates, the blade 16 of center rotor 7 inside is formed to contact with chamber, the outside oil suction pump housing 6 cylndrical surface wall under the influence of centrifugal force and seals, cavity volume is isolated into oil sucting cavity d and oil-discharging cavity e, due to blade periodicity eccentric rotary in outside oil scavenge pump body 6 cylinder type cavity, oil sucting cavity d and oil-discharging cavity e volume are changed, oil sucting cavity d increases gradually and forms negative pressure from oil inlet passage c oil suction, oil-discharging cavity e reduces gradually, oil pressure raises, liquid is extruded from oil discharge passage f, flow away from oil drain out b.Heat in logical oily motor-driven vane pump can be taken away with discharge fluid by the fluid that (each oil duct, gap) flows in electric machine casing 2, is dispelled the heat by the outer surface of electric machine casing 2 simultaneously.
