Embodiment
In order to the technology feature that practicality is novel, object and effect have understanding clearly, now compareing accompanying drawing and embodiment of the present utility model is described, label identical in the various figures represents identical part.
In any case each figure discussed below and be used to describe principle of the present disclosure in this patent file various embodiments only by way of illustration and should not be construed as restriction the scope of the present disclosure. It will be understood to those of skill in the art that, it is possible in the equipment of any suitable layout, implement principle of the present disclosure. The various innovative teachings of the application are described with reference to exemplary unrestricted embodiment.
In order to avoid bobbin winding head to occur conduction to contact with the conductor of surrounding, the lid of an insulation can be set on bobbin winding head, thus whole bobbin winding head is covered, consider the special construction of bobbin winding head, so just need a kind of special production technique to manufacture such lid, it is apparent that such lid volume can be bigger, thus add cost.
And if an enough big distance is set between bobbin winding head and peripheral conductor (such as end cap, step cover etc.), thus avoid therebetween conduction contact, so just can increase the length of motor, miniaturization cannot be accomplished.
The utility model provides a kind of simple scheme, it is possible to when motor length is fixing, reducing the probability that conduction contact occurs between bobbin winding head and step cover, it is with low cost, and production process also comparatively simplifies.
In one embodiment, it provides a kind of motor bearings lid insulation part, as shown in Figure 1, insulation part 10a comprises a circle insulation outer rim 12, and insulation outer rim 12 can be set on step cover 20a, realizes insulation between step cover and bobbin winding head.
Specifically, outer rim 12 extends certain length L1 along the axial X of step cover 20a, and this axial length L 1 is not less than the axial length L 2 of step cover 20b, like this, after insulation part is enclosed within step cover, it is possible in the axial direction step cover is wrapped, especially, when the axial length L 1 of outer rim 12 is greater than the axial length L 2 of step cover 20a, parcel effect is better.
In order to be enclosed within step cover 20a by stable for insulation part 10a, multiple protruding 11 can be arranged inside outer rim 12, correspondingly, the side face of step cover 20a arranges corresponding groove 21, like this, insulate part 10a can by the Qian He between protruding 11 and groove 21 comparatively stable be fixed on step cover 20a.
In order to provide insulation effect better, an end can also be set again on insulation part, as shown in Figure 2, this end 14 can extend radially inwardly certain length and formed by outer rim 12 from step cover 20b, especially, it can form a circular open, and its opening is suitable with step cover 20b openings of sizes, this kind of design can Simplified flowsheet, be convenient to better carry out processing insulating cover.
End 14 can also arrange at least one card further and buckle 18 (such as four), step cover 20b arranges position and fixed orifices 28 corresponding to quantity, the two can coordinate fixing, design can ensure that insulation part 10b and both step cover 20b's is relative fixing like this, and without the need to whether worry can the two departs from when transport, work. If adopting insulation part made of plastic, its elasticity deformation effect can be better, and operator are easy to just can to buckle 18 by card and are arranged on step cover.
Can also arranging at least one open-work 16 on end 14, the position of open-work 16 is corresponding with open holes 26 position on step cover 20b, it may be preferred that the quantity of open-work 16 can also be corresponding with the quantity of the open holes 26 on step cover 20b. Insulation part 10b can be connected step cover 20b and cover in advance on bearing support together, for workman, just it is easy to lock step cover from outside by bolt, even if bolt length is longer, also need not worry completely can occur against conflicting with insulation part, bolt can be stretched out by open-work, so just simplifies difficulty of processing and restriction chosen by part.
The utility model additionally provides a kind of motor shaft bearing member, as shown in Figure 3, comprise bearing support 30, step cover 20b and insulation part 10b, insulation part 10b is set on step cover 20b, being fixed on bearing support 30 by step cover 20b again, insulation part 10b can be connected step cover 20b and cover in advance together on bearing support 30, is so just easy to lock step cover 20b from outside by bolt 70, even if bolt length is longer, also need not worry completely can occur against conflicting with insulation part.
Simultaneously, as shown in Figure 3, the utility model additionally provides a kind of motor 90, the bearing part comprising electric machine stand 40 and be positioned on support 40, owing to being provided with insulation part 10b, can also ensure further bobbin winding head 55 can not and step cover 20b between occur conduction contact, just have enough creepage distances between winding end portion and step cover.
Motor shaft bearing member and corresponding motor illustrate although Fig. 3 is the insulation part 10b of the step cover to have end 14, but it will be understood that can also adopt the previously described step cover insulation part 10a without end 14 completely.
To sum up, the utility model embodiment provides a kind of motor bearings lid insulation part, motor bearings lid, motor shaft bearing member and motor thereof, described insulation part comprises a circle insulation outer rim 12, described outer rim 12 axially extends along described step cover, the axial length of described outer rim 12 is not less than the axial length of described step cover, and described outer rim 12 is configured as and is set on described step cover. Like this, owing to being provided with insulation part, it is also possible to ensure further bobbin winding head can not and step cover between occur conduction contact, just have enough creepage distances between winding end portion and step cover.
Herein, " schematically " expression " serves as example, example or explanation ", it should not by being described to any diagram of " schematically " herein, enforcement mode be interpreted as a kind of preferred or have more the technical scheme of advantage.
A series of detailed explanation listed above is only the concrete explanation for feasibility embodiment of the present utility model; they also are not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent embodiment of doing of spirit or change all should be included within protection domain of the present utility model.
