Abstract
The utility model discloses a gear pump rotor, include the whole cylindric rotor body that is, along the rotor hole has been seted up to rotor body's axial lead direction rotor body's a terminal surface run through to another terminal surface offered a plurality of fluted, just rotor body's outer cylindrical surface is not sealed and extends to to the one end of recess the oilhole has been seted up on rotor body's the outer cylindrical surface, just the oilhole is the inclined hole, and a plurality of hoop grooves have been seted up on the inner wall in rotor hole, just the cross -section semicircular in shape in hoop groove the hoop inslot is provided with inhales the sound cotton. The utility model has the advantages of simple structure and reasonable design, change the gear pump rotor's among the prior art structure, through being provided with the oilhole, can improve its greasy property, inhale the sound cotton through being provided with, can improve the problem that its noise is big.
Description
Technical field
The utility model relates to pump technical field, particularly relates to a kind of gear pump rotor.
Background technique
Gear pump relies on the swept volume formed between pumping cylinder and engaging gear to change and the mobile rotary pump carried liquid or make it supercharging.Form two enclosed spaces by two gears, the pump housing and front and rear covers, when pinion rotation, the volume in the space of the side that is out of gear is large from little change, forms vacuum, is sucked by liquid, and liquid from diminishing greatly, and is clamp-oned in pipeline and gone by the volume in the space of gears meshing side.Suction chamber and discharge side lean on the line of contact of two gears to separate.The pressure of the exhaust port of gear pump depends on the size of pump discharge place resistance completely.
Gear pump rotor of the prior art is continued to use initial design always and is not improved, and its performance needs further to be improved, especially its greasy property in use have much room for improvement and noise problem to be improved.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of gear pump rotor.
The utility model is achieved through the following technical solutions:
A kind of gear pump rotor, comprise overall cylindrical rotor body, direction of axis line along described rotor body offers rotor hole, an end face of described rotor body run through to other end offer some fluted, and one end of described groove is not closed and is extended to the outer cylinder surface of rotor body, the outer cylinder surface of described rotor body offers oilhole, and described oilhole is inclined hole, and on the inwall of described rotor hole, offer multiple circumferential groove, and the cross section semicircular in shape of described circumferential groove, in described circumferential groove, be provided with acoustical cotton.
As optimal technical scheme of the present utility model, one end of described oilhole starts from the outer cylinder surface of rotor body, and the other end ends on the interior edge face of groove.
As optimal technical scheme of the present utility model, described oilhole is circular port, and its diameter is 3mm-5mm.
As optimal technical scheme of the present utility model, described groove is made up of bar-shaped trough, serrate slot and kidney slot, and the other end of described oilhole communicates with kidney slot.
As optimal technical scheme of the present utility model, the quantity of described groove is even number.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, change the structure of gear pump rotor of the prior art, by being provided with oilhole, its greasy property can being improved, by being provided with acoustical cotton, the problem that its noise is large can be improved.

Fig. 2 is plan view of the present utility model;
Fig. 3 is the A-A sectional view in Fig. 2.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is axonometric drawing of the present utility model, and Fig. 2 is plan view of the present utility model, and Fig. 3 is the A-A sectional view in Fig. 2.
Present embodiments provide a kind of gear pump rotor, comprise overall cylindrical rotor body 1, direction of axis line along described rotor body 1 offers rotor hole 2, run through to other end at an end face of described rotor body 1 and offer some fluted 3, in the present embodiment, the quantity of described groove 3 is even number.And one end of described groove 3 is not closed and extended to the outer cylinder surface of rotor body 1, the outer cylinder surface of described rotor body 1 offers oilhole 4, and described oilhole 4 is inclined hole, described oilhole 4 is circular port, and its diameter is 3mm-5mm.One end of described oilhole 4 starts from the outer cylinder surface of rotor body 1, and the other end ends on the interior edge face of groove 3, and particularly, described groove 3 is made up of bar-shaped trough 30, serrate slot 31 and kidney slot 32, and the other end of described oilhole 4 communicates with kidney slot 32.By being provided with oilhole, its greasy property can be improved.
And on the inwall of described rotor hole 2, offer multiple circumferential groove 5, and the cross section semicircular in shape of described circumferential groove 5, in described circumferential groove 5, be provided with acoustical cotton.By being provided with acoustical cotton, the problem that its noise is large can be improved.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
