Abstract

The utility model discloses a kind of to angie type oil groove cycloid rotor pump, including:Pump cover, internal rotor, outer rotor, the pump housing, travelling gear, axle, bushing;Extend on the dividing plate of the pump cover to angie type seal area;And oil-feed tank is excavated on pump cover, goes out oil 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;It can either extend the oil-feed time to angie type seal area structure, complete oil-absorbing process to greatest extent, and and can is effectively sealed into, oil-out, so as to the oil absorbing effect reached;Oil storage tank is opened up, simple in construction, have clear improvement effect to cavitation in rotor;On inner and outer Rotator surface, circumferential direction uses non-smooth surface, and the reduction of corresponding velocity fluctuation and pressure fluctuation has just caused the reduction of inner and outer rotors skin friction drag, so as to realize drag-reduction effect.

Description

It is a kind of to angie type oil groove cycloid rotor pump
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.

Embodiment
As shown in Figure 1, Figure 2, it is a kind of to angie type oil groove cycloid rotor pump shown in Fig. 3, Fig. 4, Fig. 5, including:Pump cover 1, internal rotor 2nd, outer rotor 3, the pump housing 4, travelling gear 5, axle 6, bushing 7;Extend on the dividing plate of the pump cover 1 to angie type seal area 101;And Oil-feed tank 102 is excavated on pump cover 1, goes out oil groove 103;The surface circumferential direction of internal rotor 2 uses non-smooth surface;It is described outer The inner face circumferential direction of rotor 3 uses non-smooth surface.
Wherein, the internal rotor 2, the groove that the Non-smooth surface unit of outer rotor 2 is semi-cylindrical, rectangle or triangle;Non- light Sliding unit depth and internal rotor and 0.1 ~ 0.2mm of fit clearance of outer rotor, Non-smooth surface cell height are 4 ~ 6mm, Non-smooth surface list Within member centered on rotor axis, it is uniformly distributed in 360 °, two neighboring Non-smooth surface unit angle is 6 °;And in internal rotor, outer Four layers of non-smooth surface interlaced with each other are set on the axial direction of rotor, and adjacent two layers Non-smooth surface unit angle is 3 °;It is described Pump cover 1 on the contact surface of internal rotor 2 with opening up oil leab 104;Pipe dope is offered on the inner surface of the bushing 7 Road.
Of the present utility model a kind of to angie type oil groove cycloid rotor pump, it can either extend oil-feed to angie type seal area structure Time, oil-absorbing process is completed to greatest extent, and can is effectively sealed into, oil-out, so as to the oil absorbing effect reached;Open up oil storage Groove, simple in construction, have clear improvement effect to cavitation in rotor;On inner and outer Rotator surface, circumferential direction uses non-smooth surface, The reduction of corresponding velocity fluctuation and pressure fluctuation has just caused the reduction of inner and outer rotors skin friction drag, so as to realize drag reduction Effect;The oil leab opened up provides lubricating oil for bushing and axle, substantially reduces its abrasion.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New spirit and scope are defined, on the premise of the utility model design conception is not departed from, ordinary people in the field couple The all variations and modifications that the technical solution of the utility model is made, the scope of protection of the utility model, this reality all should be dropped into With new claimed technology contents, all record in detail in the claims.
