Below with reference to Fig. 1 and Fig. 2, the electric machine assembly 100 according to the utility model embodiment is described.Comprise motor 1 and bucker 2 according to the electric machine assembly 100 of the utility model embodiment.As shown in Figure 1, the motor shaft 12 that motor 1 comprises fuselage 11 and extends upward from fuselage 11, bucker 2 is located at fuselage 11 upper ends and motor shaft 12 passes bucker 2.By making motor shaft 12 through bucker 2, the restriction that can avoid 2 pairs of motor shafts of bucker 12 to rotate, interference etc.
Be understandable that, in some practical situations, motor 1 vertically is located at some device below sometimes, for example, shown in Fig. 2, there is shown the scheme of installation of electric machine assembly 100 of the present utility model and wind wheel 200, wherein the axis of wind wheel 200 is vertically located, and electric machine assembly 100 of the present utility model is located at the below of wind wheel 200 so that wind wheel 200 is driven.In actual conditions, probably appear in when operation such as refrigeration plant, ventilation equipment etc. on the parts such as wind wheel 200 and condensation occurs, condensation drops onto the phenomenon on motor 1 downwards, now water droplet may be along the parts clearance on motor 1 end cap or gap flow direction motor 1 inside between motor shaft 12 and fuselage 11, so long-time, easily cause motor 1 stator, rotor oxidation or get rusty, can the circuit for generating short circuit when serious, the fault such as stuck.
Here be understandable that, at some in other practical situations, electric machine assembly 100 can also be arranged on other any positions of its device driven, can be located at left and right sides, upside of its device driven etc. such as electric machine assembly 100, wherein according to the actual installation situation of electric machine assembly 100, bucker 2 can be located on the relevant position of motor 1, with backstop water, splashes on motor 1.
Particularly, in embodiment more of the present utility model, comprise that according to the electric machine assembly 100 of the utility model embodiment the first cover body 21, the first cover bodies 21 comprise end cap portions 211 and protuberance 212, wherein end cap portions 211 is mated and is located on fuselage 11 ends with fuselage 11 ends.In example as depicted in figs. 1 and 2, end cap portions 211 is located at fuselage 11 upper ends, and particularly, end cap portions 211 can be located at fuselage 11 end cap tops.Protuberance 212 is located on end cap portions 211 and along motor shaft 12 and extends upward, and is understandable that, protuberance 212 can closely be wrapped in motor shaft 12 outsides, to prevent that water from dripping along motor shaft 12, flows to fuselage 11 downwards.
Preferably, end cap portions 211 is slightly larger than fuselage 11 size in the radial direction in size in the radial direction.End cap portions 211 can all cover fuselage 11 in the radial direction thus, avoids water to flow to fuselage 11 sides, further guarantees the dash effect of bucker 2.Wherein be understandable that, " being slightly larger than " refer to end cap portions 211 in the difference of size in the radial direction and fuselage 11 size in the radial direction in grade, for example the difference of the diameter of the diameter of end cap portions 211 and fuselage 11 can be in 5～50mm scope.
The water wherein fallen from top can flow down along the surrounding edge of end cap portions 211, particularly, as shown in Figure 1, can be provided with to guide the guide portion of current around the surrounding of end cap portions 211, so that water flows down more swimmingly end cap portions 211.Alternatively, this guide portion can be to form along carrying out chamfered by the surrounding in end cap portions 211, can be wherein rounding, chamfer etc., at this, is not particularly limited.
Wherein, preferably, the roof and wall structure of end cap portions 211 can be become to dome shape (scheming not shown), i.e. middle protrusion, the downward-sloping shape of surrounding, can make thus current flow down along the roof of end cap portions 211 more rapidly, avoid water droplet to converge on end cap portions 211.
In embodiment more of the present utility model, protuberance 212 comprises body 2121 and contraction flow region 2122.Body 2121 can form cylindrical shape, contraction flow region 2122 also can form cylindrical shape, contraction flow region 2122 is located at body 2121 tops coaxially, and the diameter of contraction flow region 2122 is less than between the diameter of body 2121 and body 2121 and contraction flow region 2122 and is connected with transition part 2123.That is to say, protuberance 212 is configured to big top and small bottom structure, as depicted in figs. 1 and 2, thus can be under the prerequisite of the package action that guarantees 212 pairs of motor shafts 12 of protuberance, what water droplet was flowed downward is faster, avoids converging of water droplet.
In preferred embodiments more of the present utility model, the first cover body 21 is interior can be provided with shock absorber part (scheming not shown), and shock absorber part can closely cooperate by the interference mode with motor shaft 12, can closely be wrapped in motor shaft 12 outsides.By this shock absorber part is set, can play better protection, spacing fixing, cushioning effect to motor 1.Wherein the material of shock absorber part is not particularly limited, such as being rubber parts, felt member etc.
As depicted in figs. 1 and 2, bucker 2 also comprises: the second cover body 22.The second cover body 22 is located on motor shaft 12 and is positioned at the first cover body 21 tops, and the second cover body 22 lower ends are opened wide and the free end of protuberance 212 extend in the second cover body 22, and motor shaft 12 is through the roof of the second cover body 22.Can utilize thus 22 pairs of the first cover bodies 21 of the second cover body to play the effect of blocking, can further avoid the water droplet fallen from top to flow in bucker 2 along the gap between the contraction flow region 2122 of motor shaft 12 and the first cover body 21.Advantageously, the cross section of the second cover body 22 increases from the top down gradually, can facilitate thus water successfully to flow down along the outer surface of the second cover body 22.
Particularly, the second cover body 22 can be arbitrarily with the fit system of motor shaft 12, for example the second cover body 22 can be connected by buckle structure with motor shaft 12, can also be connected by securing member, and the second cover body 22 can also be engaged on motor shaft 12 by the interference mode.Wherein, in example as shown in Figure 1, the roof that motor shaft 12 is provided with buckling groove 121, the second cover bodies 22 is fastened in buckling groove 121.Can make thus the second cover body 22 more various with the mounting means of motor shaft 12.Particularly, this buckling groove 121 can form by mill processing in the enterprising driving of motor shaft 12.In actual applications, the second cover body 22 can carry out specific design according to specific requirement with the mounting means of motor shaft 12.
Advantageously, seal (scheming not shown) can be set between the second cover body 22 and motor shaft 12, can prevent thus in actual conditions, water droplet flows in bucker 2 along the roof of the second cover body 22 and the gap of motor shaft 12, can further improve thus the dash effect of bucker 2.
Wherein, in example as shown in Figure 1, can be provided with the annular stop 122 that is located at the second cover body 22 tops on motor shaft 12.By this annular stop part 122 is being set, thereby can further prevent that the water droplet fallen from top from flowing in bucker 2 along the roof of the second cover body 22 and the gap between motor shaft 12.
Be all known according to other configuration examples of the electric machine assembly 100 of the utility model embodiment for ordinary skill person as the structure particularly of motor 1 etc. and operation, no longer describe in detail here.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
