Abstract
The utility model discloses an electric motor rotor balancing piece, include the balancing piece at the terminal surface of rotor, the balancing piece becomes the arc form, and the balancing piece is equipped with 6 perforating holes. The utility model discloses the comparison of use is convenient on the rotor terminal surface can to superpose several as required, durable, and 6 perforating holes of setting have improved the fastness that multi -disc balancing piece and rotor are connected.
Description
Technical field
The utility model relates to machine field, specifically, is a kind of motor rotor balance weight.
Background technology
In general, motor is made up of stators and rotators two parts, and the iron core that stators and rotators folds collection by silicon steel chip is respectively formed.Single stator lamination is circular, is folded collect the stator core that forms cylindrically by lamination.Rotor is cylindric, and rotor to be directly pressed on bent axle and to insert in the cylinder cavity of stator core, has air-gap to be separated by between rotor and stator.Stator embeds the winding that enamelled wire is coiled into, stator winding outside source current by time produce magnetic field.Rotor have electric current by time, interact with stator field, produce electromagnetic torque and also rotate in stator.
When the rotating shaft of rigid body is by barycenter, and when being the principal axis of inertia, during Rigid Body in Rotation With, there is not bearing moving constraint power, claim this phenomenon to be dynamic balancing.Dynamic balancing is actually unbalance dynamic, is used on rotating parts and the high equipment of required precision.Any rotor, when rotating around its axis, produces centrifugal force due to the non-uniform mass relative to axis.This uneven centrifugal action can cause vibration on rotor bearing, produce the wearing and tearing of noise and acceleration bearing, so that have a strong impact on performance and the life-span of equipment, balance bad meeting and make that rotating parts is on-stream to be flown away from away, and in rotor production process, due to the impact of various factors, the pore of foundry goods as uneven in material or shrinkage cavity, the error of pts wt and mismachining tolerance etc., capital causes the imbalance of rotor weight, therefore, rotor needs calibration balance after assembling completes, the motor of more than six grades or rated speed are 1000 turns, divide and following motor, its rotor only needs school static balance, other rotor just needs to correct dynamic balancing.
When rotor is in dynamic balancing, all adopts at present generally balance clay to keep balance, balance clay is easy to use, curing rate than very fast, but like this after Long-Time Service, balance clay and be easy to fly out, make rotor produce vibration in stator.
At present, existing balance weight is generally arrange through hole at two ends, centre arranges and to be concavo-convexly buckled together by polylith balance weight, and do dynamically balanced demand to meet rotor, motor generally needs 4-8 sheet balance weight, the increasing number of balance weight, rotor motion gets up, and balance weight and the fixing of rotor are not very firm, leave space between the mid portion of balance weight and rotor, to ensureing that the dynamic balancing of rotor has a certain impact, just need the installation fastness problem considering balance weight.
Utility model content
Utility model object: the purpose of this utility model is to provide a kind of motor rotor balance weight for deficiency of the prior art, this balance weight is firm with the fixed form ratio of rotor, effectively ensure that the demand of rotor dynamic balancing.
Technical scheme: for achieving the above object, a kind of motor rotor balance weight described in the utility model, is included in the balance weight of the end face of rotor, balance weight camber shape, and balance weight is provided with 6 through holes.
Further, described balance weight two ends become round and smooth arc.
Further, the through hole spaced set on described balance weight.
Further, described balance weight several superposition uses, and according to the demand of rotor balancing, polylith balance weight is carried out superposition and uses.
Further, described through hole is of a size of 9mm.
The beneficial effects of the utility model are:
A kind of motor rotor balance weight described in the utility model, several balance weights can be superposed as required on rotor end-face, use more convenient, durable in use, balance weight surface arranges 6 through holes, and the installation of balance weight and rotor is firm, it is tightr that each balance weight is fitted, when rotor high-speed operates, balance weight can not be caused to be out of shape, to improve the fastness that multi-disc balance weight is connected with rotor.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the connection diagram of rotor of the present utility model and balance weight.
In figure: 1 balance weight, 2 through holes, 3 armature spindles, 4, rotor.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
A kind of motor rotor balance weight as described in the utility model in Fig. 1, is included in the balance weight 1 of the end face of rotor 4, and balance weight 1 camber shape, fits tightly with rotor 4, be placed in the edge on rotor 3 top.Balance weight 1 is provided with 6 through holes 2, is set in qually spaced on balance weight 1, and rotor 4 and balance weight 1 are fixed by screw, improve the fastness that multi-disc balance weight 1 is connected with rotor 4.Balance weight 1 two ends become round and smooth cambered design, make dynamically balanced needs according to rotor 3, and balance weight 1 can use, until meet rotor 3 to do dynamically balanced requirement as required in several superpositions.
Balance weight 1 structure axisymmetricly, symmetry axis both sides respectively distribute 3 through holes, balance weight 1 penetrates through hole 2 by screw and is fixedly connected with rotor 4, be conducive to improving the stability of balance weight 1 on rotor 4, fitted by screw between each balance weight 1 relatively tightr, when rotor 4 runs up, can not be too fast because of rotating speed, cause balance weight 1 to be out of shape, and then cause rotor 3 unbalance and vibrate.Balance weight 1 outward flange and inward flange are the circular arc of concentric shafts, the outward flange of inward flange and armature spindle 3 is fitted, the outward flange of balance weight 1 and the outward flange of rotor 3 are fitted, when balance weight 1 is installed, first balance weight 1 is cleared up, burr on corner angle and projection are carried out suitable finishing, then by place for balance weight 1, balance weight 1 is stablized motionlessly to fit with rotor 4 tip edge, with screw, balance weight 1 and rotor 4 end face are fixed again, and then by corresponding with screw for through hole 2 corresponding for second piece of balance weight 1, superpose the number of balance weight as required, on the balance weight 1 successively balance weight 1 of needs being added to previous, after isoequilibrium block 1 installs, nut and screw are tightened, ensure the stability of balance weight 1 and rotor 4, screw exposed parts outside balance weight 1 is unsuitable long, fastening backlash deadlock jail.
Embodiment is only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
