Description
Technical field
The utility model relates to a kind of vacuum pump, and more particularly, it relates to a kind of vacuum pump rotor interface arrangment.
Background technique
At present, motor car engine is all furnished with vacuum pump mostly, and this vacuum pump is used as the vacuum power source of the systems such as brake power-assisted, cruise, airconditioning control.Traditional automobile vacuum pump mostly is blade type, comprising the pump housing, pump cover, rotor, blade etc., utilizing the connection of machine shaft and vacuum pump rotor, for driving described vacuum pump steady running.
The process that present most of rotor is being installed all can utilize screw etc. to be fixed by the clamp that rotor is connected with rotating shaft, clamp will be caused so structurally comparatively fixing, trickle activity can not be accomplished, and the structure such as screw needs screwin one by one in the process of installing, install consuming time comparatively of a specified duration, dismounting is also inconvenient.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of vacuum pump rotor interface arrangment, utilizes criss-cross clamp to dock with epitrochanterian draw-in groove, is fixed simultaneously by rivet, can guarantee that the power of rotating shaft can be stablized transmission by clamp, and easy for installation.
For achieving the above object, the utility model provides following technological scheme: a kind of vacuum pump rotor interface arrangment, comprise rotor, described rotor side offers draw-in groove, also include the clamp with described draw-in groove clamping, described clamp is provided with two the first clamping blocks be symmetrical set, described first clamping block is used for and rotating shaft clamping, described clamp is also provided with two and is symmetrical set the second clamping block, described first clamping block and the second clamping block, described first clamping block and the second clamping block are that cross structure distributes, described clamp center is provided with the groove of kidney-shaped, columniform projection is provided with in described draw-in groove, described projection is positioned at described groove, described projection upper punch is provided with the rivet with clamp of conflicting.
The utility model is set to further: described first clamping block is rectangular shape, and is highly greater than the groove depth of described draw-in groove, and the height of described second fixture block is less than the groove depth of described draw-in groove.
The utility model is set to further: described first clamping block, have gap between the second clamping block and described draw-in groove inwall.
Compared with prior art, the utility model has the advantage of, the interface arrangment of cross shape, the transmission carrying out moment that rotating shaft and rotor can be stable can be guaranteed, and rectangular first clamping block above clamp can insert rotating shaft, guarantees to link with rotating shaft.When installing, directly clamp is put into draw-in groove, just can then be riveted over by rivet, clamp has just been fixed on inside rotating shaft, installs comparatively quick and convenient.And the clamp of inside be in can local movement state, the reality of rotating shaft can be had more, adjustment upper/lower positions slightly, ensure clamp can with stable the docking of rotating shaft.
Accompanying drawing explanation
Fig. 1 is the erection drawing of the utility model vacuum pump rotor interface arrangment embodiment;
Fig. 2 is the structural drawing of the utility model vacuum pump rotor interface arrangment embodiment;
Fig. 3 is the structural drawing of the utility model vacuum pump rotor interface arrangment embodiment rotor;
Fig. 4 is the structural drawing of the utility model vacuum pump rotor interface arrangment embodiment clamp.
Reference character: 1, rotor; 11, draw-in groove; 12, projection; 2, clamp; 21, the first clamping block; 22, the second clamping block; 23, groove.
Embodiment
Referring to figs. 1 through Fig. 4, the utility model vacuum pump rotor interface arrangment embodiment is described further.
A kind of vacuum pump rotor 1 interface arrangment, comprise rotor 1, described rotor 1 side offers draw-in groove 11, also include the clamp 2 with the clamping of described draw-in groove 11, described clamp 2 is provided with two the first clamping blocks 21 be symmetrical set, described first clamping block 21 for rotating shaft clamping, described clamp 2 is also provided with two and is symmetrical set the second clamping block 22, described first clamping block 21 and the second clamping block 22.
Be round structure in the middle of clamp 2, described first clamping block 21 and the second clamping block 22 distribute in cross structure.First clamping block 21 to the second clamping block 22 is large a little, and a bit described clamp 2 center is provided with the groove 23 of kidney-shaped, and the structure of kidney-shaped is not clearly, can be used for clamp 2 swing slightly in inside.Be provided with columniform projection 12 in described draw-in groove 11, described projection 12 is positioned at described groove 23, and described projection 12 upper punch is provided with the rivet with clamp 2 of conflicting.
Wherein, the first clamping block 21 is rectangular shape, and is highly greater than the groove depth of described draw-in groove 11, directly can penetrate rotating shaft.The height of described second fixture block is less than the groove depth of described draw-in groove 11 slightly.
The interface arrangment of cross shape, can guarantee the transmission carrying out moment that rotating shaft and rotor 1 can be stable, and rectangular first clamping block 21 above clamp 2 can insert rotating shaft, guarantees to link with rotating shaft.When installing, directly clamp 2 is put into draw-in groove 11, just can then be riveted over by rivet, clamp 2 has just been fixed on inside rotating shaft, installs comparatively quick and convenient.
Wherein, as shown in Figure 2, gap is had between described first clamping block 21, second clamping block 22 and described draw-in groove 11 inwall.Clamp 2 substantially can be suitable with clamp 2 when being installed on rotor 1, but exist gap also can local the activity doing some, the reality of rotating shaft can be had more like this, adjustment upper/lower positions slightly, ensure clamp 2 can with stable the docking of rotating shaft.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
