Description
Technical field
It the utility model is related to a kind of to angie type oil groove cycloid rotor pump, belong to lubricating oil pump field.
Background technology
Traditional run-in index oil groove and angle formula oil groove is linked up it is necessary to suitably increase in order to avoid being occurred to early into and out of hydraulic fluid port
Add the area of sealing area, this may result in the reduction of oil-feed groove area, so as to also result in the generation of oil suction deficiency problem；When
When rotor thickness is thicker, fluid is difficult to be filled into rotor bottom so that rotor bottom is also easy to produce the phenomenon of cavitation；Again due to interior turn
Son have impact on pump housing service life with outer rotor interface damping problem and the friction problem of bushing and axle.
Utility model content
To solve the above problems, the utility model proposes a kind of to angie type oil groove cycloid rotor pump, its oil absorbing effect is good,
Frictional dissipation is small.
It is of the present utility model a kind of to angie type oil groove cycloid rotor pump, including：Pump cover, internal rotor, outer rotor, the pump housing, biography
Moving gear, axle, bushing；Extend on the dividing plate of the pump cover to angie type seal area；And oil-feed tank, fuel-displaced is excavated on pump cover
Groove；The surface circumferential direction of the internal rotor uses non-smooth surface；The inner face circumferential direction of the outer rotor uses Non-smooth surface
Surface.
Further, the internal rotor, the groove that outer rotor Non-smooth surface unit is semi-cylindrical, rectangle or triangle；It is non-
0.1 ~ 0.2mm of fit clearance of smooth units depth and internal rotor and outer rotor, Non-smooth surface cell height are 4 ~ 6mm, Non-smooth surface
Within unit centered on rotor axis, it is uniformly distributed in 360 °, two neighboring Non-smooth surface unit angle is 6 °；And internal rotor,
Four layers of non-smooth surface interlaced with each other are set on the axial direction of outer rotor, and adjacent two layers Non-smooth surface unit angle is 3 °.
Further, oil leab is opened up on the contact surface of the pump cover and internal rotor.
Further, pipe dope road is offered on the inner surface of the bushing.
Compared with prior art, it has the advantages that the utility model：It is of the present utility model a kind of to angie type
Oil groove cycloid rotor pump, it can either extend the oil-feed time to angie type seal area structure, complete oil-absorbing process, and can to greatest extent
Effectively it is sealed into, oil-out, so as to the oil absorbing effect reached；Oil storage tank is opened up, it is simple in construction, have substantially to cavitation in rotor
Improvement；On inner and outer Rotator surface, circumferential direction uses the reduction of non-smooth surface, corresponding velocity fluctuation and pressure fluctuation
Just the reduction of inner and outer rotors skin friction drag has been caused, so as to realize drag-reduction effect；The oil leab opened up be bushing with
Axle provides lubricating oil, substantially reduces its abrasion.
