Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The sectional drawing structural representation of the dynamically balanced magnetic suspension rotor of capable of regulating that Fig. 1 provides for the utility model.
Embodiment
The utility model discloses dynamic balance adjusting apparatus and method in a kind of magnetic suspension rotor chamber.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out to clear, complete description, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, dynamic balance adjusting apparatus and method sectional drawing structural representation in the magnetic suspension rotor chamber that Fig. 1 provides for this law is bright.
The utility model provides dynamic balance adjusting apparatus and method in a kind of magnetic suspension rotor chamber, comprises dynamic balancing adjustment tank in impeller of rotor, rotor magnetic suspension structure, rotor case, chamber, rotor axis micropore, molten melt drop conveying micropin.Described magnetic suspension adjustment tank and body are cylindric, are placed in the cavity in described magnetic suspension rotor.Scheme of the present utility model, for the problem of non-uniform of rotor case, is adjusted the mass distribution in rotor cavity by molten melt drop, makes rotor reach dynamic balancing.
According to embodiment of the present utility model, described rotor by impeller of rotor 1., rotor magnetic suspension structure 2., rotor case 3., dynamic balancing adjustment tank 4., molten melt drop micropin 5., rotor axis micropore 6., 7. molten melt drop form.Impeller of rotor effect is 1. that convection cell acting, the effect 2. of rotor magnetic suspension structure are the suspensions that realizes all degrees of freedom of rotor.2. 1. impeller of rotor be not main contents of the present utility model with rotor magnetic suspension structure, therefore do not launch narration, represents only as signal in figure.3. rotor case has wrapped up all outer surfaces of rotor, and has certain quality nonuniformity, is the main source of dynamic unbalance.4. dynamic balancing adjustment tank is arranged in the cavity of rotor, and its matrix can be 2. different from rotor magnetic suspension structure.6. 5. molten melt drop micropin be inserted in rotor by rotor axis micropore, and insertion depth can be adjusted arbitrarily.5. molten melt drop micropin is sent and approximate is spherical molten melt drop 7..
Molten melt drop 7. leave molten melt drop micropin 5. after, under the effect of gravity, fall, fall into dynamic balancing adjustment tank 4..4. dynamic balancing adjustment tank has many, is axial distribution.5. insert the degree of depth of rotor cavity by adjusting molten melt drop micropin, can control molten melt drop and 7. fall into dynamic balancing adjustment tank any one groove 4..By adjusting the angle of swing of rotor entirety around axle, can control molten melt drop and 7. fall on dynamic balancing adjustment tank any one circumferential position 4..That is to say, by apparatus and method described in the utility model, can control molten melt drop and 7. drop on rotor dynamic balancing adjustment tank any axial position 4. and any circumferential position.
After 7. molten melt drop drops on pre-set dynamic balancing adjustment tank a certain axially circumferentially definite position 4., 4. molten melt drop heat passive equilibrium adjustment tank 7. absorbs, and 7. molten melt drop can solidify and stick to dynamic balancing adjustment tank and 4. go up.7. molten melt drop does not affect flesh and blood of the present utility model with the material that 4. dynamic balancing adjustment tank adopts.For instance, 4. dynamic balancing adjustment tank adopts copper, and 7. molten melt drop adopts terne metal conventional in electron trade.Terne metal is melting at lower temperature, and the terne metal drop after melting has very high surface tension, can condense and be spherical.In the time that 7. spheroidal fused slicker solder drop drops on dynamic balancing adjustment tank and 4. go up, because copper and terne metal have good wettability, in the time that solidifying, 4. goes up being attached to firmly copper dynamic balancing adjustment tank terne metal.
Under the assistance of surveying instrument, according to the dynamic balancing reduction value and the correction position that record, repeat said process, utilize molten melt drop, constantly adjust the feature of dynamic balance of rotor.Finally, the dynamic unbalance situation of rotor is lowered to an acceptable scope gradually.After dynamic balancing adjustment finishes, molten melt drop micropin 5. will from rotor axis micropore 6. extract out.Rotor axis micropore diameter 6., below 0.5mm, can complete self-shutoff after utilizing laser scorification, finally carries out corresponding surface treatment.Because rotor axis micropore is 6. in rotor axis place, and there is no additional substance in the process of laser scorification shutoff, therefore rotor axis micropore laser scorification shutoff process 6. does not affect the dynamic balance performance of rotor entirety.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to these embodiments' multiple amendment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
