Abstract
The utility model relates to a power source hydraulic pump in a hydraulic system, which comprises a case 1, an oil distributing case 2 which is arranged in the case 1, a rotating shaft 4 which is arranged in the center of the case 1, a vane wheel body 8 which is arranged on the rotating shaft 4. The utility model is characterized in that the vane wheel body 8 and a side ring 11 are arranged on the rotating shaft 4 in the center of the case 1, inclined at an angle with one another, the vane wheel body 8 and the side ring 11 are provided with vane grooves which are provided with vanes 3, and the excircle surface of the vane wheel body 8 is a spherical surface. The utility model has the advantages of compact construction, few components and small size. In addition, for the small sliding frictional resistance of the contact surface and the uniform variation rate of the hermetic cavity, the utility model also has the advantages of small output pressure oil flow pulsation, uniform and stable flow rate, little noise, high efficiency, good suction capacity, high operating pressure and large flow quantity.
Description
The utility model relates to the power source oil hydraulic pump in a kind of hydraulic system.
Adopt blade hydraulic pump generally can be divided into vane pump, plunger pump, lobed rotor pump at present.For the further surface friction drag that reduces blade and contact element, thereby improve pressure, flow, reduce noise.So design following technical proposal.
The purpose of this utility model provides a kind of by impeller body and side ring and the angle that tilts, and makes it constantly change a kind of oil hydraulic pump of the cavity volume that impeller body and side ring and blade surrounded in rotary course.
The purpose of this utility model can realize by following technical proposal:
The utility model comprises the oilcan of joining body in shell, the shell, the shell center has is equipped with impeller body, it is characterized in that in a rotating shaft, the rotating shaft: described shell center has is equipped with impeller body and side ring and the angle that tilts in the rotating shaft.Have blade groove with side ring on the described impeller body, blade is housed in the blade groove.The outer garden face of above-mentioned described impeller body is a sphere.The working principle of impeller type oil hydraulic pump: if will satisfy the basic work requirement of displacement pump, just must change the volume of blade with the cavity volume that is surrounded between impeller body and the side ring, the i.e. continuous varying cyclically of volume volume in the impeller rotary course, can be designed to for this reason blade in the blade groove that impeller body is opened can about move back and forth, and the spacing that is designed to side ring and impeller body end face constantly evenly changes.When impeller rotates, on the impeller body everywhere the spacing with side ring constantly change, force blade in blade groove, to be done about back and forth fore and aft motion realize the requirement that airtight cavity volume volume constantly changes.
The utility model has following advantage: the impeller type oil hydraulic pump has compact structure, uses component few, and volume is little.Little owing to the surface of contact sliding-frictional resistance in addition, and airtight cavity volume rate of change is even.The pressure oil output flow pulsation of impeller type oil hydraulic pump is minimum, and flow velocity is uniform and stable, and noise is little, the efficient height.Suction capacity is good, the working pressure height, and flow is big.
Below in conjunction with accompanying drawing and implement that the utility model will be further described:
Accompanying drawing 1 is a schematic diagram of the present utility model;
Accompanying drawing 2 is a topology view of the present utility model;
Accompanying drawing 3 is the sectional view of topology view A-A of the present utility model;
Embodiment presses accompanying drawing 2.The utility model comprises shell 1, joins oilcan body 2 in the shell 1, and there is a rotating shaft 4 at the center of shell 1, and impeller body 8, described shell 1 center are housed in the rotating shaft 4 to be had impeller body 8 and the side ring 11 and the angle that tilts are housed in the rotating shaft 4.Have blade groove with side ring 11 on the described impeller body 8, blade 3 is housed in the blade groove.Install second mate's plain thrust bearing 10 additional between side ring 11 outer surfaces and stator 9, rotating shaft 4 is fixed on the stator 9 by radial ball bearing 6, bearing support 7, bearing gland 5.The outer garden face of above-mentioned described impeller body 8 is a sphere.The impeller type oil hydraulic pump is constantly to change with the cavity volume volume that is surrounded between blade 3 and the side ring 11 by impeller body 8, moves back and forth about making blade 3 in blade groove.Because the surface of contact sliding-frictional resistance is little, and airtight cavity volume rate of change is even.The pressure oil output flow pulsation of impeller type oil hydraulic pump is minimum, and flow velocity is uniform and stable, and noise is little, the efficient height.Suction capacity is good, the working pressure height, and flow is big.
Claims (2)
1, a kind of impeller type oil hydraulic pump, comprise having in shell 1, the shell 1 and join oilcan body 2, shell 1 center and have in a rotating shaft 4, the rotating shaft 4 and impeller body 8 is housed, it is characterized in that: there is the impeller body 8 and the side ring 11 and the angle that tilts that is equipped with in the rotating shaft 4 at described shell 1 center, have blade groove with side ring 11 on the described impeller body 8, blade 3 is housed in the blade groove.
2, a kind of impeller type oil hydraulic pump according to claim 1 is characterized in that: the outer garden face of above-mentioned described impeller body 8 is a sphere.
