Embodiment
For making those of ordinary skill in the art be expressly understood technical problem to be solved in the utility model, technical scheme and useful technique effect more, below in conjunction with drawings and Examples the utility model is further elaborated.
Consult Fig. 2, rotor field spider 1 disclosed in the utility model is applied on the micromachine, is the indispensable parts of micromachine.Usually, respectively be provided with a rotor field spider 1 at the place, two ends of the rotor 2 of micromachine, the usefulness that wears for the rotating shaft 20 in this rotor 2 is to realize the setting of rotor 2.
In conjunction with Fig. 3 and shown in Figure 4, so that first embodiment of the present utility model to be described.In this embodiment, this miniature motor rotor support 1 includes a bracing frame 10, and this bracing frame 10 includes a top board 100, and the centre of this top board 100 is formed with a socket 101, this socket 101 is used for taking in axle sleeve 12, and supplies in the installation setting of this axle sleeve 12.Preferably, axle sleeve more than 12 is designed to the drum type structure, and 101 of this sockets correspondingly are designed to the billiard table shape structure towards the end face protrusion of this top board 100, to cooperate the location and installation of this axle sleeve 12.
As shown in drawings, this bracing frame 10 includes a top board 100, this top board 100 bends downwards from its both end sides place and extends and be formed with a support arm 102, two support arms 102 respectively and stretch out and respectively be formed with a supporting bracket 103 that is roughly parallel to this top board 100 from its lower end side respectively.In conjunction with Fig. 2, during assembling, two supporting brackets 103 are supported on the stator 3 of micromachine, and via securing member 22(screw for example) in addition fastening, and realize the fixed installation of rotor field spider 1.
Consult Fig. 3 and Fig. 4, in the recessed two axial draw-in grooves 120 respect to one another that are formed with of the outer surface of this axle sleeve 12, and the place, edge is formed with two clamping projectioies 142 respect to one another in the opening 140 of this tight loop 14, when tight loop 14 was assembled with axle sleeve 12, two clamping projectioies 142 snapped into respectively among two draw-in grooves 120.Like this, be connected to the madial wall of this draw-in groove 120 by the side of this clamping projection 142, and can stop the rotation of this axle sleeve 12, thereby this axle sleeve 12 is followed the rotor rotation when having prevented micromachine work effectively, simultaneously, because this clamping projection 142 can be axially movable in this draw-in groove 120, do not stop the axial adjustment of this axle sleeve 12, thereby the free adjustment that can guarantee this axle sleeve 12 is concentric.Preferably, the place, both sides of this clamping projection 142 is formed with a side shield 143 separately, by the setting of side shield 143, increased the contact area of this clamping projection 142 with these draw-in groove 120 madial walls, so that this clamping projection 142 is located this axle sleeve 12 more reposefully.In the embodiment shown in the figures, this draw-in groove 120 is formed in the groove of these axle sleeve 12 outer surface for the both ends open breakthrough form, can be by being processed to form in the outer surface of this axle sleeve 12 such as mode such as die-cut.Draw-in groove 120 is designed to the shown structure of accompanying drawing, makes this clamping projection 142 easily be placed among this draw-in groove 120, and is convenient to the assembling between these rotor field spider 1 each parts.
The width of this clamping projection 142 is slightly less than the width of this draw-in groove 120, makes that this clamping projection 142 can be axially movable neatly in this draw-in groove 120, and preferably, the difference of both width keeps 0.1～0.3mm to be advisable.
The utility model cooperates the mode of draw-in groove 120 to locate axle sleeve 12 by clamping projection 142, play and prevent that effectively axle sleeve 12 from following the effect that rotor rotates, so, can reduce reed 141 for the thrust of axle sleeve 12, the free adjustment that is beneficial to this axle sleeve 12 is concentric.Can be by the quantity that reduces reed 141, the modes such as contact area that reduce reed 141 and axle sleeve 12, to alleviate tight loop 14 for the dynamics that compresses of axle sleeve 12.
In conjunction with Fig. 5 and shown in Figure 6, so that second embodiment of the present utility model to be described.In this embodiment, this miniature motor rotor support 1 includes a bracing frame 10, an axle sleeve 12 and a tight loop 14, wherein, this tight loop 14 is along being formed with three equally distributed oblique reeds 141 along the place in its opening 140, and these reeds 141 pressures are touched in the outer surface of this axle sleeve 12 and axle sleeve 12 are positioned on the top board 100 of this bracing frame 10.The recessed axial draw-in groove 120 that is formed with of the outer surface of this axle sleeve 12, be formed with a clamping projection 142 along the place in the opening 140 of this tight loop 14, this clamping projection 142 snaps among this draw-in groove 120 and plays the effect of location axle sleeve 12, can prevent effectively that axle sleeve 12 from following rotor and rotating.The difference of this embodiment and first embodiment is that the set quantity of reed 141, clamping projection 142 and draw-in groove 120 is different.
In conjunction with Fig. 7 and shown in Figure 8, so that the 3rd embodiment of the present utility model to be described.In this embodiment, this miniature motor rotor support 1 includes a bracing frame 10, an axle sleeve 12 and a tight loop 14, wherein, this tight loop 14 is along being formed with three equally distributed oblique reeds 141 along the place in its opening 140, and these reeds 141 are crimped on the outer surface of this axle sleeve 12 and axle sleeve 12 are positioned on the top board 100 of this bracing frame 10.The recessed axial draw-in groove (not illustrating among the figure) that is formed with of the outer surface of this axle sleeve 12, be formed with a clamping projection 142 on the madial wall of the socket 101 of this top board 100, this clamping projection 142 snaps among this draw-in groove and plays the effect of location axle sleeve 12, can prevent effectively that axle sleeve 12 from following rotor and rotating.In this embodiment, clamping convexes to form in the madial wall place of the socket 101 of top board 100, yet, it will be appreciated by those skilled in the art that ground, this clamping projection also can be formed at other suitable location on this mounting panel 100.The difference of this embodiment and above-mentioned two embodiment is that this clamping projection 142 is formed at the diverse location place of this rotor field spider 1, and planform is also slightly different.
In sum, in the miniature motor rotor support disclosed in the utility model, its outer surface in axle sleeve 12 is recessed into and is formed with at least one draw-in groove 120, and on tight loop 14 or top board 100, forming at least one clamping projection 142, this clamping projection 142 snaps among this draw-in groove 120 and plays the effect of location axle sleeve 12.Like this, both can prevent effectively that axle sleeve 14 from following rotor and rotating, it is concentric for the free adjustment that the thrust of axle sleeve 12 is beneficial to this axle sleeve 12 to reduce reed 141 again, solve existing miniature motor rotor support bottom bracket axle existing double-barreled question has been set, helped to improve the product quality of micromachine.
The above only is preferred embodiment of the present utility model, but not the utility model is done any pro forma restriction.Those skilled in the art can impose the various changes that are equal to and improvement on the basis of above-described embodiment, and all equivalent variations of doing in the claim scope or modification all should fall within the protection range of the present utility model.
