Abstract
The utility model relates to an external-rotor motor end cover, which comprises an end cover external body (1) and an end cover internal body (2). The end cover internal body (2) is connected with an end cover shaft (3). The external-rotor motor end cover is characterized in that a plurality of parallel shaft grooves (4) are arranged on the end cover shaft (3); and the shaft grooves (4) form a ring around the end cover shaft (3). As the ring-shaped shaft grooves are arranged, aluminum powder generated by friction when the end cover shaft is in interference fit can be accommodated, electricity leakage due to the generation of the aluminum powder does not happen, possibilities that the motor is short-circuited can be reduced, and security is improved.
Description
Technical field
The utility model relates to a kind of external rotor electric machine accessory, is a kind of electric leakage, safe end cap of outer rotor motor of being difficult for specifically.
Background technology
Along with scientific and technical progress, in HVAC, refrigeration and building service industry, people progressively adopt external rotor electric machine to replace inner rotor motor, thereby save space, minimizing energy consumption, reduction noise, and external rotor electric machine is progressively at home and abroad used widely.End cap of outer rotor motor is its indispensable assembly, and the existing isolation motor of end cap plays a protective role, and also needs live wire to pass through it and is connected with extraneous power supply unit.In the electric motor end cap using at present, the end-cover axle in general electric motor end cap is all a cylinder, and end cap is because interference fit can produce aluminium powder, and under High Rotation Speed, easily displacement and cause occurring electric leakage of aluminium powder, easily damages motor, has reduced fail safe.
As mentioned above, prior art exists following not enough: the problems such as the suitable easily electric leakage of existing end cap of outer rotor motor, fail safe are bad.
Summary of the invention
The utility model has solved the problems such as the end cap of outer rotor motor that prior art exists easily leaks electricity, fail safe is bad, and a kind of difficult electric leakage, safe end cap of outer rotor motor are provided.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of end cap of outer rotor motor, comprise end cap ectosome and end cap endosome, described end cap endosome connects end-cover axle, it is characterized in that described end-cover axle is provided with some parallel axial troughs, described axial trough circularizes around end-cover axle.This axial trough is superficial, its cross section camber body, and stress is not concentrated, and can not reduce the intensity of end-cover axle, and axial trough is ring seal, and self is parallel to each other axial trough, goes back heel end lid axial end parallel simultaneously.The aluminium powder that end-cover axle interference fit produces can be expressed to axial trough the inside, can not be displaced to other places while guaranteeing High Rotation Speed, is difficult for electric leakage, and fail safe is good.
As preferably, between described end cap ectosome and end cap endosome, be provided with more palace groove, groove outside in described more palace is provided with some rhones.More palace groove can buffering liquid for this, allows the liquid such as water droplet flow out end cap from rhone, or evaporates, and can keep dry, and plays good moisture-proof role.
As preferably, described end cap endosome is provided with some reinforcings footpath, and this reinforcing footpath is provided with recess.Reinforce footpath and strengthened the intensity of end-cover axle, recess can make the moisture in it walk, and is difficult for tide.
As preferably, described axial trough is 2-5.Axial trough equidistantly distributes in end-cover axle, take 3 as good.
The utility model is skillfully constructed, and by the setting of axial trough in end-cover axle, makes it have compared with the prior art following beneficial effect:
1, the aluminium powder producing is difficult for displacement;
2, be difficult for electric leakage, moistureproof, fail safe is good.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described further.
Embodiment.See Fig. 1, a kind of end cap of outer rotor motor, comprise end cap ectosome 1 and end cap endosome 2, described end cap endosome 2 connects end-cover axle 3, described end-cover axle 3 is provided with three parallel axial troughs 4, described axial trough 4 circularizes around end-cover axle 3, and three axial troughs 4 self are parallel to each other and are equidistant, simultaneously also parallel with end-cover axle 3 end faces.This axial trough 4 can hold the aluminium powder that end-cover axle 3 produces because of interference fit, is difficult for electric leakage, has promoted fail safe.
Wherein, be provided with more palace groove 5 between described end cap ectosome 1 and end cap endosome 2, groove 5 outsides, described more palace are provided with rhone 6, and described end cap endosome 2 is provided with reinforces footpath 7, reinforces footpath 7 and extends in end-cover axle 3, and this reinforcing footpath 7 is provided with recess 8.Described more palace groove 5 can buffering liquid, allows the liquid such as water droplet flow out end cap from rhone 6, can keep dry, and plays good moisture-proof role.
It is apparent to one skilled in the art that the utility model can be changed into various ways, such change do not think depart from scope of the present utility model.Allly so the apparent modification of described those skilled in the art will be included in to the scope of this claim.
