Description
Technical field
The invention relates to a kind of motor configuration, the motor being easy to assemble location bearing that especially a kind of assembling for stator pack and bearing and locate mode are improved.
Background technology
Please refer to shown in Fig. 1, is TaiWan, China application No. 02201612.0 " stator of motor and bearing fixing device " utility model patent case.This utility model patent case discloses a kind of existing motor 8, and this existing motor 8 comprises shell block 81, rotor 82 and a stator 83.This shell block 81 is provided with an axle bed 811, and this axle bed 811 inside arranges a bearing 812; This rotor 82 pivot joint is incorporated into this bearing 812; It is outside that this stator 83 is incorporated into this axle bed 811, and the upper insulation plate 831 of this stator 83 has a ring lip 832, and this ring lip 832 crimps this bearing 812; Whereby, this shell block 81, rotor 82 and stator pack 83 can assemble to form a motor configuration mutually.
Above-mentioned existing motor 8 mainly utilizes above-mentioned ring lip 832 to crimp bearing 812, to reach the function preventing bearing 812 from deviating from; But, the ring lip 832 of this existing motor 8 is the ring flange extended towards the central radial level of said axle seat 811, this ring lip 832 only can touch the apical margin of said axle seat 811 and the end face of this bearing 812 as shown in the figure simultaneously, though can prevent this bearing 812 from deviating from, this ring lip 832 also cannot reach the effect pressing down this bearing 812 of location further.
Therefore, when supposing the apical margin of the end face of above-mentioned bearing 812 in the axial direction because of dimensional tolerance a little less than said axle seat 811, because above-mentioned ring lip 832 bottom surface first will certainly touch the apical margin of this axle bed 811, cause producing gap between this ring lip 832 bottom surface and this bearing 812 end face, though this bearing 812 is unlikely to deviate from this axle bed 811, only this bearing 812 also cannot push against and be fixed on this axle bed 811 inside by this ring lip 832, this bearing 812 is caused easily to loosen, when above-mentioned rotor 82 rotates in the process of start, easily produce improper noise.
When supposing again the apical margin of the end face of above-mentioned bearing 812 in the axial direction because of dimensional tolerance a little more than said axle seat 811, due to the ring flange that above-mentioned ring lip 832 extends for radial level, therefore, this bearing 812 easily forces the deflection of this ring lip 832 to increase, and then this maximum fairness limit of ring lip 832 itself may be exceeded, cause this ring lip 832 to produce fracture situation.
Please refer to shown in Fig. 2, is TaiWan, China application No. 200510108285.1 " motor and bearing arrangement thereof " patent of invention case.This patent of invention case discloses another kind of existing motor 9, and this existing motor 9 has an axle sleeve 91, and this axle sleeve 91 outside is provided with a stator 92, and this axle sleeve 91 inside is provided with a bearing 93, and this bearing 93 can combine for rotor 94 pivot joint; This axle sleeve 91 inside separately arranges a covering members 95, and this covering members 95 has a turning point 951, and this turning point 951 has a groove 952; Wherein this turning point 951 abuts this bearing 93 end face, this groove 952 as buffering area, to overcome the problems such as assembly error.
Though above-mentioned existing motor 9 can utilize the turning point 951 of covering members 95 to abut above-mentioned bearing 93; But, this covering members 95 is for being assembled in the component of above-mentioned axle sleeve 91 inside, this covering members 95 is only to prevent this bearing 93 from deviating from this axle sleeve 91, when this covering members 95 fails closely to be fixed on this axle sleeve 91 inside because of dimensional tolerance, namely effectively this bearing 93 cannot be pushed against and be fixed on this axle sleeve 91, this bearing 93 can be caused equally easily to loosen, and in above-mentioned existing motor 9 operation, produce improper noise; Moreover this existing motor 9 is when actual assembled, and said stator 92 and covering members 95 must be assembled in this axle sleeve 91 respectively, once cannot complete the assembling of this stator 92 and the location of this bearing 93, cause assembling convenience not good.
