Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings the grounding wire component mounting structure 10 of the motor according to the embodiment of the present invention is described.
As depicted in figs. 1 and 2, casing 100, support plate 200 and grounding wire component 300 is comprised according to the grounding wire component mounting structure 10 of the motor of the embodiment of the present invention.
Support plate 200 is located in the outside wall surface of casing 100, and support plate 200 is provided with screw mounting hole.Grounding wire component 300 is provided with through hole, and grounding wire component 300 passes through through described through hole and the screw 400 be engaged in described screw mounting hole is arranged on support plate 200.Wherein, described screw mounting hole can be screwed hole, and also can be tapping screw bottom outlet, screw 400 can replace with bolt.
According to the grounding wire component mounting structure 10 of the motor of the embodiment of the present invention, the outside wall surface of casing 100 arranges support plate 200, can grounding wire component 300 be arranged on support plate 200 by screw 400, like this can by increasing the thickness of support plate 200 to increase the length of fit of screw 400 and described screw mounting hole, make the length of fit of screw 400 not by the restriction of casing 100 thickness, can avoid thus occurring sliding dental phenomenon, significantly improve the reliability after grounding wire component 300 installation.In addition, screw 400 is arranged on support plate 200 and to be positioned at casing 100 outside, and screw 400 can be made like this to affect electric clearance, thus without the need to stator end being processed very short, and then turn-to-turn short circuit ratio can be ensured, significantly improve the rate of finished products of stator.Therefore, according to the grounding wire component mounting structure 10 of the motor of the embodiment of the present invention have not easy to slip teeth, connect reliable, the advantage such as turn-to-turn short circuit ratio and stator defect rate can be reduced.
Below with reference to the accompanying drawings the grounding wire component mounting structure 10 of the motor according to the specific embodiment of the invention is described.
As depicted in figs. 1 and 2, casing 100, support plate 200 and grounding wire component 300 is comprised according to the grounding wire component mounting structure 10 of the motor of the embodiment of the present invention.
Specifically, support plate 200 can be welded in the outside wall surface of casing 100, support plate 200 can be fixed on casing 100 thus, and both firm and reliable connection.
Further, described screw mounting hole is flanging bore, when not increasing the thickness of support plate 200, can increase the length of fit of described screw mounting hole and screw 400 like this, thus avoid sliding tooth, improve grounding wire component 300 install with support plate 200 after reliability.
In concrete examples more of the present invention, as depicted in figs. 1 and 2, support plate 200 comprises two connecting portions, 210, two support portions 220 and an installation portion 230.
In the outside wall surface that two connecting portions 210 are welded on casing 100 and spaced apart setting.Two support portions 220 are connected with the two relative edges of two connecting portions 210 respectively.Installation portion 230 is connected with two support portions 220 respectively, installation portion 230 is spaced apart with the outside wall surface of casing 100 under the support of two support portions 220, described screw mounting hole is located on installation portion 230, and grounding wire component 300 is arranged on the surface away from casing 100 of installation portion 230 by screw 400.So both can ensure that screw 400 and described screw mounting hole had larger length of fit, and can prevent again screw 400 and casing 100 from interfering.
Particularly, as depicted in figs. 1 and 2, two connecting portions 210 are welded on the periphery wall of casing 100, and two connecting portions 210 extend along the axis of casing 100 in parallel to each other, and two connecting portions 210 are along the spaced apart setting of circumference of casing 100.Thus without the need to bending connecting portion 210, connecting portion 210 just can be made to adapt to the radian of the outer peripheral face of casing 100, thus not only can facilitate welding of the periphery wall of connecting portion 210 and casing 100, and the reliability after both welding can be improved.
Further, two support portions 220 extend along the axis of casing 100 in parallel to each other, and angle between two support portions 220 and the connecting portion 210 be connected is equal.That is, the angle between a support portion 220 and the connecting portion 210 be connected equals the angle between another support portion 220 and the connecting portion 210 be connected.The uniform force of support plate 200 can be made thus to distribute, thus the intensity of support plate 200 can be improved.
In specific embodiments more of the present invention, installation portion 230, two support portions 220 and two connecting portions 210 are integrated part.In other words, support plate 200 is formed by an entire plate bending.The structural strength of support plate 200 can be ensured thus.
Advantageously, as shown in Figure 2, the junction of installation portion 230 and two support portions 220 and two support portion 220 arc transition equal to the junction of two connecting portions 210 respectively.Can avoid like this stress concentration phenomenon appears in support plate 200, thus the bearing capacity of support plate 200 can be improved.
