Abstract
The present invention relates to a shock absorption method of a small-size motor, which comprises the following steps that (1) an elastic bearing shock absorption ring 1 is made and is provided with a hollow cylinder body 13, one end is provided with an annular end wall 12, and the other end is completely open; (2) the shock absorption ring 1 is tightly sheathed on an outer ring of a rotor bearing 6, and the outer surface of the end wall 12 faces to the inner surface of a bearing socket 42; (3) a rotor shaft and the bearing 6 which is sheathed with the shock absorption ring 1 are stuffed in the bearing socket 42 of a bearing bracket 4, and the rotor shaft, the bearing 6 and the bearing socket 42 are in an elastic close fit state; (4) the bearing bracket 4 is fixed on a stator lamination 9, and the bearing shock absorption ring 1 is formed in the mode of mould pressing by using silicon rubber. The method and the shock absorption ring used in the present invention relieve the shock of the motor at the time of operation. The performance of the motor is enhanced, and simultaneously, the motor is conveniently disassembled and assembled; the production cost is reduced.
Description
Technical field the present invention relates to miniature motor, comprises low power and electric motor structure fractional horse-power, relates in particular to bearings mounted method of miniature motor and used bearing shock absorbing ring.
The miniature motor of background technology prior art, the single phase series motor that for example is used for vacuum cleaner, in the spindle socket of the rolling bearing support of its rotor commutator end, be ease of assembly and centering, between bearing outer ring and spindle socket inwall, adopt sliding fit usually.Simultaneously, when the rigid bearing support is on stator lasmination, also to leave certain axial movement space for rotor.Although between spindle socket inner face and bearing face, added the curved packing ring of wave packing ring or elasticity, but the vibrations in the time of all can not eliminating motor operation preferably, even bearing outer ring rotates displacement with respect to the spindle socket inwall sometimes, is commonly called as " circle of acting as a travelling agent ", causes serious consequence.
The summary of the invention the technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of bearing shock absorbing ring that the miniature motor running time can alleviate the method for vibrations and adopt usefulness that this method is adorned that is used for.
The present invention solve the technical problem can be by realizing by the following technical solutions: propose and implement a kind of shock-dampening method that is used for miniature motor, be exactly, when the described motor of assembling, the shock absorbing ring that one usefulness highly elastic material is made tightly is placed on the outer ring of rotor bearing, then with armature spindle and on be with described shock absorbing ring bearing fill in the spindle socket of bearing of motor support, be the resilient tight fit state; The motor of assembling like this, when adding electric operation, vibrations will significantly alleviate.
The present invention solve the technical problem also and must realize by taking following technological means: design, a kind of bearing shock absorbing ring that is used for miniature motor of making, this shock absorbing ring has cylindrical trunk, axially shorter, hollow, the one end has the ring-type end wall, the other end is unlimited fully, and described shock absorbing ring is to use the silicon rubber die forming.
Compare with prior art, vibrations alleviated when the inventive method and used shock absorbing ring made the motor operation, and performance improves, and went back easy disassembly simultaneously, reduced production costs.
Description of drawings Fig. 1 is a kind of miniature motor orthographic projection schematic diagram that adopts the inventive method assembling;
Fig. 2 is the broken section enlarged drawing at Fig. 1 bearing-commutator position;
Fig. 3 is the main cutaway view of looking of bearing shock absorbing ring 1 orthographic projection that the present invention is used for miniature motor;
Fig. 4 is the orthographic projection vertical view of Fig. 3 bearing shock absorbing ring 1.
Embodiment is described in further detail below in conjunction with the most preferred embodiment shown in each accompanying drawing: propose and implement a kind of miniature motor that is applicable to, the shock-dampening method of vacuum cleaner for example, see figures.1.and.2, when the described motor of assembling, the shock absorbing ring 1 that one usefulness highly elastic material is made tightly is placed on the outer ring of rotor bearing 6, then with armature spindle and on be with shock absorbing ring 1 bearing 6 fill in the spindle socket 42 of bearing of motor support 4, be the resilient tight fit state, and the described support of bearing 4 is fixed on the motor stator lamination 9.The motor of assembling like this, when adding electric operation, vibrations will significantly alleviate.
The present invention is used for the bearing shock absorbing ring 1 of miniature motor, as shown in Figure 3, Figure 4, cylindrical trunk 13 is arranged, and is axially shorter, hollow, and the one end has ring-type end wall 12, and the other end is unlimited fully.The outer surface of this ring-type end wall 12 is provided with the jut 14 that extends vertically at least two places, and they evenly distribute on the same circumference of described outer surface.The jut 14 that extends vertically at 8 places normally is set, and they have under the situation of error at motor general assembly axial dimension, play a part to regulate the rotor assembly axial location, have improved the accuracy of rotor assembly position.
Also be evenly distributed with at least two fillets 18 of extending vertically on the outer wall of the cylindrical trunk 13 of described shock absorbing ring 1, they normally 6.Described shock absorbing ring 1 silicon rubber die forming, shore hardness are 65 to 75 degree.It also has good oil resistance and elasticity except having suitable like this hardness, thus can noise reduction, damping.Compare the method for rigid bearing outer rings such as adopting wave packing ring, curved packing ring and press, the behavior in service of motor increases, but also has prolonged useful life.
Bearing shock absorbing ring 1 of the present invention is used for fixing the outer ring 61 of miniature motor rolling bearing 6, can not occur " circle of acting as a travelling agent " phenomenon in the time of can making bearing operation.Because shock absorbing ring 1 has suitable elasticity, and be distributed with 6 places fillet 18 on the outer wall of its trunk 13, thus can be good fit with the spindle socket 42 on the support of bearing 4, reduced requirement to spindle socket 42 machining accuracies, also correspondingly reduced cost certainly.The characteristics of described 6 places fillet 18 and favorable elasticity have guaranteed the accuracy when shock absorbing ring 1 cooperates with spindle socket 42 reliably, have avoided use prior art riveting housing washer 61 and cause its distortion, have prolonged useful life of bearing 6.Again because need not spreading glue, so manufacturability is relatively good, easy accessibility.
