Description
Technical field
The utility model relates to field of mechanical technique, about a kind of permanent magnetic servo motor rotor, especially about a kind of permanent magnetic servo motor rotor dynamic balancing mud fixed form.
Background technology
Rotor is the rotating part of motor.It is made up of rotating shaft, rotor core and rotor windings, and rotor core (magnetic core) plays the important and pivotal role inside whole motor, and it is used for increasing the magnetic flux of inductance coil, has realized the maximum conversion of electromagnetic power.Widely, stepping motor, AC/DC motor, reducing motor, external rotor electric machine, motor with cup rotor, synchronous asynchronous motor etc. has and utilizes more widely its range of application.For finished product motor, the effect that motor iron core plays inside motor accessory is more crucial.Want to allow the overall performance of a motor be improved, just need the performance promoting motor iron core.Usual this performance can adopt the material improving core stamping, adjusts the permeability of its material, and the mode such as size of iron loss controlled well solves.A good motor iron core needs, by the metal stamping die of precision, to adopt the techniques such as automatic riveting, then utilize the punching press of high precision punch table out.The benefit done like this is, farthest can ensure the integrity degree of the plane of its product, farthest ensure its Product Precision.Although the raising precision that existing product is all being tried one's best, still can there are some vibrations in rotor in the process used, therefore in order to slow down the vibrations degree of rotor, usually at rotor end-face configuration balance weight.In order to can be good at stable equilibrium block, more rotor there is also mounted side pressure dish.Although which serves certain effect, which increase the weight of whole rotor, too increase manufacturing cost simultaneously.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, low cost of manufacture, technique simple permanent magnetic servo motor rotor dynamic balancing mud fixed form.
For achieving the above object, the utility model have employed following technical proposal: a kind of permanent magnetic servo motor rotor dynamic balancing mud fixed form, comprise rotating shaft, rotating shaft outer surface is provided with rotor core, and rotor core exterior surface is equipped with magnet steel, and the end face that rotor core is connected with rotating shaft is provided with jump ring, it is characterized in that, described magnet steel surface is provided with stainless steel sleeve, and the end of this stainless steel sleeve protrudes from the end face of magnet steel and rotor core, forms the groove can placing balance mud.
In above-mentioned a kind of permanent magnetic servo motor rotor dynamic balancing mud fixed form, described magnet steel is concordant with the end face of rotor core.
In above-mentioned a kind of permanent magnetic servo motor rotor dynamic balancing mud fixed form, the end of described stainless steel sleeve protrudes from the end face 5-8mm of magnet steel and rotor core.
Compared with prior art, the utility model has the advantage of: the groove formed by stainless steel sleeve and magnet steel end face can directly put into balance mud, simplify structure and the weight of whole rotor, reduce the moment of inertia of rotor, improve the response speed of whole electric system, improve the installation reliability of rotor core, simultaneously reduced cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art 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, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of permanent magnetic servo motor rotor dynamic balancing mud fixed form, comprises rotating shaft 1, rotating shaft outer surface is provided with rotor core 2, rotor core exterior surface is equipped with magnet steel 3, and the end face that rotor core is connected with rotating shaft is provided with jump ring 4, and described magnet steel is concordant with the end face of rotor core.Described magnet steel surface is provided with stainless steel sleeve 5, and the end of this stainless steel sleeve protrudes from the end face of magnet steel and rotor core, forms the groove 6 can placing balance mud.By the groove formed, can place balance weight in the optional position in groove, play the effect of balance, improve the stability of rotor, in the technical program, the end of stainless steel sleeve protrudes from the end face 5-8mm of magnet steel and rotor core.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
