By adopting technique scheme, bearing working is steady, reliable, noiseless, and circular degree is accurate, not easily produces friction, also serve the effect of fixed rotor rotating shaft simultaneously, prevent rotor from shaking excessive, it also avoid and directly contact with ring support, damping spring is set, certain gap is had between the circle of Compress Spring and circle, when being subject to external applied load, spring contraction distortion, stores deformation energy, good stability. and noise is low. and vibration isolating effect is good. the advantages such as long service life.
The utility model is set to further: the lateral wall of described annular inner ring is provided with some first fixed blocks, described annular outer shroud inwall is installed with in some second fixed blocks, described damping spring one end be arranged on first fixing in, the other end is arranged in the second fixed block.
By adopting technique scheme, spring is fixedly secured in fixed block by being stablized, the vibration that can not be produced by electric machine rotation and occurrence positions offsets or drops.
The utility model is set to further: described damping spring is in evenly axially arranging.
By adopting technique scheme, evenly arranging and spring shock absorption mechanism can be made to stablize, shock wave during rotor turns can be absorbed uniformly, can shockproof effect be significantly improved.
The utility model is set to further: described cover plate is provided with bolt hole and location hole, and location hole and motor casing can location fit.
By adopt technique scheme, cover plate can and casing simply effectively fixing, Stability Analysis of Structures is firm.
The utility model is set to further: described bearing is ball bearing.Ball bearing can bear radial load simultaneously and axial load more can be applicable to micro motor.

Embodiment
Referring to figs. 1 through Fig. 2, the shockproof lid embodiment of a kind of motor of the utility model is described further.
The shockproof lid of a kind of motor, is made up of bump protection ring 2 and cover plate 1.After the outside electricity provided of coil reception of stator, form the magnetic field of alternation, rotor core rotates under the magnetic field of alternation, and armature spindle rotates under the drive of rotor core thereupon, thus outside outputting power.Cover plate 1 central authorities have a circular hole 3, its size and axis of rotor rotation in the same size, bump protection ring 2 to be profiles be one protruding cylindrical, this bump protection ring 2 center of circle and the circular hole center of circle are concentric circles, are installed in the middle position of cover plate 1.A ball bearing 4 is fixed with in bump protection ring central authorities, its bearing inner ring 42 size and circular hole 3 in the same size, be provided with ball bearing can reach in work and reduce coefficient of friction, rub little, wear and tear low, bearing working is steady, reliable, noiseless, also serve the effect of fixed rotor rotating shaft simultaneously, prevent rotor from shaking excessive.Can also add a small amount of lubricating oil in bearing, under hydrodynamic lubrication condition, the undeveloped life of the lubricated oil content of slidingsurface directly contacts, and can also greatly reduce friction loss and surface abrasion, oil film also has certain vibration absorption ability.
Ring support 5 is made up of fixed block, annular inner ring 52 and annular outer shroud 53, and ball bearing outer shroud 43 is sheathed in annular inner ring 52, and with annular inner ring 52 interference fit, prevent ball bearing 4 landing.Annular inner ring 52 and annular outer shroud 53 between be evenly provided with 8 damping springs 41, the lateral wall of annular inner ring 52 is provided with some first fixed blocks 511, described annular outer shroud inwall is installed with in some second fixed blocks 512, described damping spring 41 one end is arranged in the first fixed block 511, the other end is arranged in the second fixed block 512, spring is fixedly secured in fixed block by being stablized, the vibration that can not be produced by electric machine rotation and occurrence positions offsets or drops.Arrange damping spring 41, have certain gap between the circle of Compress Spring and circle, when being subject to external applied load, spring contraction distortion, stores deformation energy, the advantages such as good stability, noise are low, vibration isolating effect good, long service life.8 damping springs evenly arrange and spring shock absorption mechanism can be made to stablize, and can absorb shock wave during rotor turns uniformly, can significantly improve shockproof effect.Ring support height is identical with ball bearing height, forms concentric circles with ball bearing inner ring, outer shroud.
Cover plate 1 is also provided with two screwed holes and is positioned at bump protection ring both sides, what be convenient to electric machine casing is fixing, and cover plate 1 four angles are also provided with salient point and shrinkage pool, and electric machine casing corresponding section is provided with shrinkage pool and salient point, convenient location, fixing rear motor and cover plate 1 structure more stable.
Certainly, above-described embodiment be only the utility model preferred embodiment, more change can be had during practical application, such as, spring with can not be that bolt is connected between bearing and turned legs, can riveted joint be made; Or fixing with motor can not be shrinkage pool and salient point, can make hinged or bayonet arrangement; Or screwed hole quantity can be two or more, and such change also can realize the purpose of this utility model.
