The utility model discloses a vacuum pump blade body surface is equipped with the several recess, can carry out the oil storage, at the rotatory in -process of blade, can reduce the friction of blade and vacuum pump intracavity lateral wall and rotor inslot side to reduce heat production, noise abatement, reduce power consumption, increase of service life.
Description
Technical field
The utility model relates to a kind of for the blade in vacuum pump, particularly but be not limited to be used in automobile application on.The utility model relates to the vacuum pump with this blade.
Background technique
Vacuum pump application, in service braking sytem system, uses rotating vane vacuum pump to provide negative pressure of vacuum for vacuum booster.When the rotor rotates, blade rotates along with rotor and passes rotor to keep fitting with shell body wall on its every one end, and the slot between blade and wall is sealed by oil film.Upon the rotation of the blade, produce vacuum, make gas enter in chamber by entrance, then this gas is discharged by outlet when blade rotary.
Due to rubbing contact all the time between inside blade and vacuum pump intracavity sidewall and rotor, very easily wear and tear, along with the wearing and tearing of blade, frictional loss also constantly increases, the gap of blade and intracavity sidewall and rotor becomes greatly simultaneously, and cause sealing to reduce, whole efficiency reduces further.Chinese patent CN20350006U discloses in a kind of vacuum pump and inside blade and rotor, is provided with cylindrical rolling element to reduce the friction between movement process Leaf and rotor, but the cylindrical rolling element of this design and rotor interior side contacts mode are point cantact, very large vibrations and noise can be produced in movement process, and its sealing is not good yet, affect the working effect of vacuum pump.
Model utility content
Model utility object: in order to overcome above deficiency, the purpose of this utility model is to provide that a kind of frictional loss is little, the blade of long service life and have the vacuum pump of this blade.
Technological scheme: the utility model discloses a kind of vacuum pump vanes with oil groove, comprise blade body and end, upper and lower, forward and backward four faces of described blade body are equipped with the oil storage grooves of several proper alignment.Vacuum pump vanes body surface of the present utility model is provided with several groove, can carry out oil storage, in blade rotary process, can reduce the friction inside blade and vacuum pump intracavity sidewall and rotor, thus reduce heat production, reduce noise.In addition, this design can also increase the sealing effect of vacuum chamber, increases effect of vacuum pump further.Also reduce the weight of blade simultaneously, thus reduce inertia torque, decrease power consumpiton.
Improve as one of the present utility model, the vacuum pump vanes of above-mentioned band oil groove, described body and end detachably, are coincide by shape and interconnect.The utility model can be designed to body as required and end is dismountable part, wherein only on body, is provided with oil groove.Body and end can be applied identical or different materials and be made.This design can facilitate as required replaces body or end, facilitates replacing or the maintenance of blade.
Improve as one of the present utility model, the vacuum pump vanes of above-mentioned band oil groove, described blade comprises shell and inserts, and upper and lower, forward and backward four faces of described shell are equipped with the oil storage grooves of several proper alignment.The utility model can select different materials for inserts and shell as required, meets this body high strength and high-precision requirement simultaneously, overcomes the shortcoming that homogenous material cannot meet the demands simultaneously.The vacuum pump vanes of above-mentioned band oil groove, described shell is that thermoplastic or thermosetting plastics are made, and described inserts is made up of high-strength material, combined by these parts with injection molding forming method.The utility model selects the high-strength materials such as steel, aluminium material or polymer composite in blade insert, improves product strength.The thermal expansion coefficient of inserts is all close with vacuum pump case material with blade shell, so just can ensure that blade can not crack because of expanding with heat and contract with cold of inserts, also ensures that the gap change of blade at different temperature and between vacuum pump housing is little simultaneously.And wrap up wear-resisting thermoplastic or thermosetting plastics at shell, because its plastic layer is thin, injection moulding contour projector is less, substantially increases the precision of body.These parts linked together by the method for molding and forming, allow its once-through and the blade shape error produced is very little, precision is high.After injection moulding, do not need to carry out machining again.When mass production, inserts is processed in advance except first meets need of production, and other both periods carry out simultaneously, substantially reduce generating period.With injection molding forming method, these parts are combined, allow its once-through, reduce cost of production.
Improve as one of the present utility model, the vacuum pump vanes of above-mentioned band oil groove, described end is hook.The utility model adopts hook shaped tip design at the body width end of blade, and required material is few, and fabricating cost is low, and in addition, this design also reduces the weight of blade, thus reduces inertia torque, decreases power consumpiton.This hook shaped tip designs for elastic ends simultaneously, and sealing can be made tightr.
Technique scheme can be found out, the utility model has following beneficial effect: provide that a kind of frictional loss is little, the blade of long service life.
The vacuum pump that the utility model provides comprises vacuum pump vanes, and this vacuum pump vanes has above-mentioned technique effect, and the vacuum pump comprising this vacuum pump vanes also should have identical technique effect.
