Description
Technical field
The invention belongs to motor component, particularly a kind of buckle is in conjunction with the motor pedestal of tool elasticity shank central siphon.
Background technology
As shown in Figure 1, the motor pedestal of known locating structure of sensing element ' the small heat-dissipating fan stator with ' disclosed tool central siphon is to make that central siphon 11a is one-body molded to be formed on the pedestal.The preferable system of central siphon 11a is made by plastic cement material, and its periphery system can supply tight fit combined circuit plate 12a and stator pack 13a, and week is in order to ccontaining bearing 14a in it.
As shown in Figure 2, the motor pedestal of known ' the stator combined structure of small heat-dissipating fan ' disclosed tool central siphon comprises pedestal 10b and central siphon 11b.Pedestal 10b is provided with and extends upward the axis hole 101b that forms ring flange 102b.The preferable system of central siphon 11b is made by metal material, and its top is provided with the ring antelabium 111b of big external diameter.Central siphon 11b with its bottom and body respectively tight fit be incorporated in the centre bore 130b of pedestal 10b ring flange 102b and stator pack 13b, with season the big outer-diameter ring antelabium 111b in its top with stator pack 13b snaps into position on pedestal 10b.
As shown in Figure 3, the U.S. the 5th, 267, the motor pedestal of No. 842 ' small-sized DC fan ' disclosed tool central siphons comprises housing 1c, pedestal 10c and central siphon 11c.
Housing 1c is with several rib supporting bases 10c.
Pedestal 10c system is made by plastic cement material, and the one-body molded formation central siphon 11c that makes progress.
The body periphery of central siphon 11c and in week shoulder 111c, 112c, 113c respectively tight fit in conjunction with stator pack 13c, circuit board 12c and at least one be the bearing 14c of ball bearing.
Though simple in structure, the assembling of the motor pedestal of above-mentioned disclosed three kinds of tool central siphons also can reduce manufacturing cost easily.Yet in actual or use, but can derive many problems:
1, the motor pedestal of disclosed three kinds of tool central siphons, the internal and external circumferential of its central siphon 11a, 11b, 11c
Must carry out time-consuming turning or drilling processing, the accurate location of ability and populated circuit board 12a, 12b, 12c, stator pack 13a, 13b, 13c and bearing 14a, 14b, 14c, otherwise will cause circuit board 12a, 12b, 12c, stator pack 13a, 13b, 13c and bearing 14a, 14b, 14c to get loose.
2, the motor pedestal of disclosed three kinds of tool central siphons, when bearing 14a, 14b, 14c tight fit being incorporated in central siphon 11a, 11b, the 11c week, cause the permanent deformation of bearing 14a, 14b, 14c or central siphon 11a, 11b, 11c easily, thereby make the relative pedestal 10b of central siphon 11a, 11b, 11c, bearing 14a, 14b, 14c and rotating shaft, 10c that deflection take place.
3, the motor pedestal of tool central siphon as shown in Figure 2, it only is incorporated on the pedestal 10b in the tight fit mode for the central siphon 11b of metal material, to such an extent as to central siphon 11b still can relative to pedestal 10b rotate or on move.
4, as the motor pedestal of Fig. 1 and tool central siphon shown in Figure 3, it is shaped in stator pack 13a, 13c that central siphon 11a, 11c on the pedestal 10c is only applicable to the single default specification of assembly, if desire the stator pack of other specifications of assembly, then housing 1c, pedestal 10a, 10c and central siphon 11a, 11c must corresponding redesigns.
Therefore, when motor uses the motor pedestal of above-mentioned disclosed three kinds of tool central siphons, may cause rotate unbalance, produce noise, reduce problems such as assembly and design margin, even shorten the useful life of motor because of the stator component accidental release.
Summary of the invention
The purpose of this invention is to provide a kind of easy to process, assembling fast, in conjunction with firmly, prevent to be out of shape, buckle that assembly nargin is big is in conjunction with the motor pedestal of tool elasticity shank central siphon.
The present invention includes pedestal and central siphon; Pedestal central authorities are provided with and extend upward the axis hole that forms ring flange, are provided with location notch in the base ring flange bottom week; Central siphon is provided with locating flange and superposed at least one the elasticity shank that is positioned at the bottom, and forms hook portion in elastic hook masthead end; Central siphon is with all location notch inlay cards in its bottom locating flange and the base ring flange, central siphon is incorporated in the pedestal axis hole; Described central siphon periphery is provided with the raised line of and clip corresponding with stator pack center bore inner wall groove.
Wherein:
Central siphon system is made by elastomeric material.At least one elastic hook leverage is formed between two elongated slots.In between the elasticity shank, inwardly be convexly equipped with number in the central siphon week and use the fixture block of supporting the assembling two bearings.Blind end is formed on the central siphon bottom.Blind end is arranged with oil storage tank.Locating flange is the projection of and inlay card corresponding with all bottoms location notch in the base ring flange.The base bottom ring is established the location notch that the cross section is shapes such as triangle, square, ellipse, rectangle or pentagon; Central siphon locating flange system outwards is convexly equipped with by the central siphon bottom and and inlay card periphery corresponding with all location notchs in the base ring flange is the projection of shapes such as triangle, square, ellipse, rectangle or pentagon.The oil storage tank top is provided with the oiliness bearing bottom and grips the clasp of using spacing rotor shaft jointly.Base ring flange end face radially is provided with several fin or forms matsurface.
Owing to the present invention includes pedestal and central siphon; Pedestal central authorities are provided with and extend upward the axis hole that forms ring flange, are provided with location notch in the base ring flange bottom week; Central siphon is provided with locating flange and superposed at least one the elasticity shank that is positioned at the bottom, and forms hook portion in elastic hook masthead end; Central siphon is with all location notch inlay cards in its bottom locating flange and the base ring flange, so that central siphon is incorporated in the pedestal axis hole.During assembling motor,, central siphon is incorporated in the pedestal axis hole with all location notch inlay cards in central siphon bottom locating flange and the base ring flange, with increase bond strength and avoid central siphon in conjunction with the back relative pedestal rotate or on move; Secondly, the circuit board and the stator pack of one group of combination in advance is sheathed on the central siphon periphery in regular turn, and makes the hook portion of central siphon elastic hook masthead end be snapped in stator pack centre bore apical margin, at this moment, what can be subjected to the elasticity shank in the stator pack centre bore week temporarily opens support elastic force clip; Then, bearing is inserted week in the central siphon, so, just can outwards form hole enlargement, obtain best clip locating effect so that be sheathed on the stator pack of central siphon periphery by the elasticity shank; At last, the axostylus axostyle with rotor is hubbed in the two bearings; Promptly by the location notch of mutual inlay card and locating flange avoids the relative pedestal of central siphon to rotate or on move, more locate the axostylus axostyle of stator pack, two bearings and rotor simultaneously by the elasticity shank, thereby make the three have identical central shaft, with the reliability that promotes the stator assembling, increase rotor rotation stability, avoid motor because of the unbalance useful life that produces noise and prolongation motor.Moreover the pedestal of same specification can change central siphon fast according to product demand, for the stator pack of assembly different size, therefore, also can increase the assembly nargin of motor stator.Not only easy to process, assembling fast, in conjunction with firmly, and prevent that distortion, assembly nargin are big, thereby reach purpose of the present invention.
