Technical field
The utility model relates to a kind of driving structure for vacuum pump, is integrated with the vacuum pump of this driving structure, and the motor that disposes this vacuum pump.
Background technique
Vacuum pump (claiming again vacuum booster pump) is the power-assisted dress system of brake system and steering system.Fig. 1 shows a typical oil-sealed rotary pump 1 ' of the prior art, and this vacuum pump 1 ' is connected with extraneous by connecting key 2 ', in order to the blade (not shown) in drive shell, is rotated.As shown in Figure 2, in order to facilitate layout and the driving of vacuum pump 1 ', vacuum pump 1 ' is arranged on the rear end of camshaft 3 ' conventionally, and the connecting key of vacuum pump 1 ' inserts the stern notch of camshaft 3 ', the other end is inserted in the cross recess of rotor 4 ', thereby by camshaft 3 ', drive the rotor 4 ' of vacuum pump to rotate, and then make the eccentric blade rotary of vacuum pump inner chamber, to realize the function of vacuum pump extracting air.In order to compensate camshaft 3 ' and the deviation of rotor 4 ' on axis, connecting key 2 ' can be in the cross recess of rotor 4 ' translation ± 1mm.It is pointed out that internal rotor is provided with oil duct, machine oil lubricates connecting key by the oil duct of rotor along the direction of arrow.Because the cross moulding of rotor and connecting key is complicated, both all adopt powdered metallurgical material moulding, simultaneously in order to make the connection of camshaft and connecting key reliable, need quenching to reach the hardness of 550HV.
There is following problem in current design: 1) the more difficult processing of the cross shape of rotor tip; 2) at internal rotor, must offer oil duct to lubricate connecting key, make the structure of internal rotor very complicated; 3) between camshaft and vacuum pump, be to be rigidly connected, once the stuck fault of blade appears in vacuum pump, can damage camshaft, when serious, even make whole motor scrap; 4) vacuum pump can only be installed on camshaft rear end, and for different engine application, after camshaft, end spaces may be limited, and this just makes troubles to engine arrangement.Therefore, urgently find a kind of simple in structure, easy to process and be not easy to cause the driving structure for vacuum pump of motor damage.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of driving structure for vacuum pump, be integrated with the vacuum pump of this driving structure, and the motor that disposes this vacuum pump, thereby can effectively solve the problem of the above-mentioned and other aspect existing in prior art.
For realizing above-mentioned object, the utility model has adopted following technological scheme:
A kind of driving structure for vacuum pump, described driving structure comprises transmission device and for the bent axle of power is provided, wherein said transmission device has driving wheel, follower, and for the transmission component to described follower by the transmission of power from described driving wheel, described driving wheel is connected with described bent axle, and described follower is connected with the rotor of described vacuum pump.
In above-mentioned driving structure, preferably, described driving wheel and described follower are belt wheels, and described transmission component is ribbon.
In above-mentioned driving structure, preferably, described driving wheel and described follower are sprocket wheels, and described transmission component is chain.
In above-mentioned driving structure, preferably, being connected between described follower and described rotor is interference fit.
In above-mentioned driving structure, preferably, described rotor is formed from steel.
In above-mentioned driving structure, preferably, described belt wheel is multi-wedge belt pulley or flat tyre wheel.
A vacuum pump, described vacuum pump is integrated with above-mentioned driving structure.
A motor, described engine configurations has above-mentioned vacuum pump.
The beneficial effects of the utility model are: the driving structure for vacuum pump of the present utility model is easy to processing, simple in structure and easy for installation, not only advantageously solved the Layout Problem of vacuum pump, and can also avoid causing the problems such as motor damage due to the fault of vacuum pump.
Accompanying drawing explanation
Below with reference to drawings and Examples, the technical solution of the utility model is described in further detail.Wherein:
Fig. 1 is the structural representation of vacuum pump of the prior art;
Fig. 2 is the composition structural representation for the driving structure of the vacuum pump of Fig. 1;
Fig. 3 is an embodiment's of the driving structure for vacuum pump of the present utility model structural representation;
Fig. 4 is the sectional view for the follower of the driving structure for vacuum pump of Fig. 3 and the rotor of vacuum pump.
Embodiment
First, it should be noted that, of the present utility model for the driving structure of vacuum pump and the Structural Tectonics of vacuum pump, feature and advantage by illustrating by way of example below, yet all descriptions are only used for describing, and they should be interpreted as the utility model is formed to any restriction.In addition, in each mentioned herein embodiment, described or implicit any single technical characteristics, or be shown or lie in any single technical characteristics in each accompanying drawing, still can between these technical characteristicss (or its equivalent), proceed combination in any or delete, thereby obtain of the present utility model more other embodiments that may directly not mention in this article.
As shown in Figure 3, it schematically illustrates an embodiment's of the driving structure for vacuum pump of the present utility model structural representation on the whole.Should comprise transmission device and for the bent axle 2 of power is provided for driving structure of vacuum pump 1, wherein transmission device is provided with driving wheel 3, follower 4, and for the transmission component 5 to follower 4 by the transmission of power from driving wheel 3, driving wheel 3 is connected in fastening mode with the bent axle 2 for delivery of power, and on the housing of follower 4 and vacuum pump 1, set rotor 6 is connected in fastening mode.It should be noted that, this rotor 6 is connected with the eccentric blade of vacuum pump 1 inside, and can be by making such as metallic material such as No. 45 steel.Be appreciated that vacuum pump 1 can be installed on the accessory tapes system of motor car engine, timing chain system or be driven separately by bent axle, thereby realized the flexible arrangement of vacuum pump 1.
In conjunction with above-described embodiment, in other preferred embodiment, driving wheel 3 and follower 4 can be the belt wheels that adopts the forms such as multi-wedge belt pulley (as shown in Figure 4) or flat tyre wheel, and the transmission component 5 matching is with it such as ribbons such as belts.In addition, driving wheel 3 and follower 4 can also adopt the form of sprocket wheel, and transmission component 5 is chains in this case.Be appreciated that, owing to being separated by transmission components such as belt or chains between bent axle 2 and rotor 6, once vacuum pump 1, there is the faults such as stuck, load on belt or chain will significantly increase, as those skilled in the desired, when load surpasses critical value, belt occurs skidding or chain ruptures, thereby can effectively avoid whole motor to scrap.
