Description
Technical field
The utility model relates to cycloid rotor pump part field, specially a kind of cycloid rotor pump stator.
Background technique
Cycloid rotor pump is small in size, compact-sized, and part is few, light-weight, and smooth running, noise is small, and the service life is long.In addition it puts
The area and angular range of line impeller pump fluid into and out of window are larger, keep fluid suction abundant, and fluid makes axial sucking,
Be conducive to suck fluid under the action of centrifugal force of fluid full of between cog, " air pocket " phenomenon be not likely to produce, due to cycloid rotor pump
The plurality of advantages having is widely used as automobile, the various kinds of lubricating oil such as tractor pump.Electronic injection gasoline engine, diesel engine and accurate vehicle
The hydraulic system of bed and engineering machinery also largely uses cycloid rotor pump." stator " is one key part of cycloid rotor pump.
" stator " is mounted on cycloid rotor pump, carries considerable effect." stator " geometry is relatively simple, internal diameter
Part is made of 7 sections of circular arcs and 14 fillets, and outer radius portion is that a great circle is constituted.Stator to internal diameter precision prescribed very
Height, but also must guarantee the center of circle of stator outer circle and the centrifugation degree of rotor.Since the inseparability of stator and rotor center is to system
It makes very high with assembly precision requirement.Such as big using conventional method difficulty of processing and high production cost.For example use traditional forging
Making blank, machine adds the technique made again, and following process difficulty is very big, and especially internal diameter processing is even more extremely difficult, and part is several
The problems such as what dimensional uniformity is poor, and quality is difficult to ensure, brings high production cost, serious waste of resources etc., therefore it is badly in need of one kind
Cycloid rotor pump stator solves this problem.
Utility model content
The utility model provides a kind of cycloid rotor pump stator, can effectively solve to mention in above-mentioned background technique due to fixed
The inseparability of son and rotor center requires very high to manufacture and assembly precision.It is such as big and raw using conventional method difficulty of processing
It produces at high cost.For example machine adds the technique made again using traditional rough forging, following process difficulty is very big, especially internal diameter ruler
Very little processing is even more extremely difficult, and part geometry dimensional uniformity is poor, and quality is difficult to ensure, brings high production cost, the wasting of resources
Serious problem.
To solve the above-mentioned problems, the utility model provides the following technical solutions: a kind of cycloid rotor pump stator, including master
Body circle offers rotor rotation chamber on the inside of the main body circle, and the side of the rotor rotation chamber is provided with crescent moon arc top, described
Crescent moon arc is provided with arc tooth socket between top.
Preferably, the main body circle, rotor rotation chamber, crescent moon arc top, arc tooth socket pass through PM technique one
It is manufactured.
Preferably, the quantity on crescent moon arc top is six.
Preferably, the quantity of the arc tooth socket is six.
Compared with prior art, the utility model has the beneficial effects that the utility model is scientific and reasonable for structure, use is safe
It is convenient:
Stator uses its unique technical advance of powder metallurgy, and need to only be added by die mould, sintering, machine can reach its production
Product performance requirement.Powder metallurgy improves 75% than traditional processing means stock utilization, and work efficiency improves 30 times, reduces life
Cost is produced, reduces the waste of material, the consumption of manpower has significant contribution to society to enterprise.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.
In the accompanying drawings:
Fig. 1 is the appearance diagram of the utility model；
Fig. 2 is the main view of the utility model；
Fig. 3 is the side view of the utility model；
Figure label: 1, main body circle；2, rotor rotates chamber；3, crescent moon arc top；4, arc tooth socket.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figure 1-3, a kind of cycloid rotor pump stator, including main body circle 1, the inside of main body circle 1 offer
Rotor rotates chamber 2, and the side of rotor rotation chamber 2 is provided with crescent moon arc top 3, is provided with arc tooth socket 4 between crescent moon arc top 3, is
Alloing stator and rotor engagement, works normally, the quantity on crescent moon arc top 3 is six, and the quantity of arc tooth socket 4 is six,
In order to guarantee the precision of stator manufacture, main body circle 1, rotor rotation chamber 2, crescent moon arc top 3, arc tooth socket 4 pass through powder metallurgy
The integrally manufactured molding of technology.
Through the above technical solutions, guaranteeing the intensity and precision of stator manufacture, reduce stator when in use and rotor
Between friction, increase the service life of cycloid rotor pump, and greatly improve the manufacture efficiency of stator, saved cost,
It is more reasonably utilized resource, avoids the waste of resource.
Finally, it should be noted that being not limited to this reality the foregoing is merely the preferred embodiment of the utility model
With novel, although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, should all
It is included within the scope of protection of this utility model.
