Therefore, how reducing the temperature of bearing in motor and extend useful life of bearing, is those skilled in the art's problem demanding prompt solutions.
Summary of the invention
In view of this, the invention provides a kind of electric motor end cap, to realize reducing the temperature of bearing in motor and the object extending the useful life of bearing.The present invention also provides a kind of motor comprising above-mentioned electric motor end cap.
In order to achieve the above object, the invention provides following technical scheme:
A kind of electric motor end cap, comprises the dead eye of mounted motor axle, and around described dead eye, top surface is laid with the multiple bearing radiating ribs reducing bearing temperature, described bearing radiating ribs and described top surface affixed and deviate from described top surface and stretch.
Preferably, in above-mentioned electric motor end cap, described bearing radiating ribs is perpendicular to described top surface.
Preferably, in above-mentioned electric motor end cap, multiple described bearing radiating ribs is evenly laid in described top surface.
Preferably, in above-mentioned electric motor end cap, described bearing radiating ribs is parallel to each other to be arranged in described top surface.
Preferably, in above-mentioned electric motor end cap, it is that emitting shape is vertical with described top surface affixed that described bearing radiating ribs deviates from described dead eye direction by described dead eye court.
A kind of motor, comprises motor body and is arranged on the electric motor end cap of the axial one end of described motor body, described electric motor end cap be as weigh upper as described in electric motor end cap.
Preferably, in above-mentioned motor, the external cover cap of described motor is provided with vertically the cover cap radiating ribs reducing internal temperature.
Electric motor end cap provided by the invention, comprises the dead eye of mounted motor axle, the top surface around dead eye is provided with multiple bearing radiating ribs, and bearing radiating ribs and the affixed and direction, away from cover surface of top surface are stretched.The setting of bearing radiating ribs adds the contact area of electric motor end cap and contacting external air, more good cooling effect is stamped to motor side, obviously strengthen the cooling of atmospheric temperature to electric motor end cap top surface, thus also reduce the temperature of the bearing be connected with electric motor end cap, fairly obvious to the cooling-down effect of bearing, also reduce the temperature of whole motor, extend the useful life of bearing and whole motor.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is electric machine structure schematic diagram provided by the invention;
In upper figure:
1 be bearing radiating ribs, 2 be dead eye, 3 be motor shaft, 4 for cover cap radiating ribs.
Embodiment
The invention discloses a kind of electric motor end cap, the temperature of bearing in motor can be reduced and extend useful life of bearing.The present invention also provides a kind of motor comprising above-mentioned electric motor end cap.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, carry out clear, complete description to the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, Fig. 1 is electric machine structure schematic diagram provided by the invention.
The invention provides a kind of electric motor end cap, comprise the dead eye 2 of mounted motor axle 3, dead eye 2 surrounding top surface is laid with and reduces multiple bearing radiating ribs 1 of bearing temperature, and bearing radiating ribs 1 affixed and away from cover surface stretches with top surface.Bearing radiating ribs 1 is specially platy structure, it arranges the contact area adding electric motor end cap and contacting external air, more good cooling effect is stamped to motor side, obviously strengthen the cooling of atmospheric temperature to electric motor end cap top surface, thus also reduce the temperature of the bearing be connected with electric motor end cap, fairly obvious to the cooling-down effect of bearing, also reduce the temperature of whole motor, obviously can extend the useful life of bearing and whole motor.
In the present invention one specific embodiment, bearing radiating ribs 1 is perpendicular to top surface.Concrete, in order to make heat radiation more even, bearing radiating ribs 1 can be set perpendicular to top surface, bearing radiating ribs 1 can make the air themperature of bearing radiating ribs 1 thickness direction both sides more even perpendicular to top surface, ensure that the circulation of air is more evenly smooth and easy, and then make the heat radiation of top surface more even.
In the present invention one specific embodiment, multiple bearing radiating ribs 1 is evenly laid in top surface.Concrete, multiple bearing radiating ribs 1 evenly can be arranged on top surface, the bearing radiating ribs 1 of even setting can further more all and dispel the heat for top surface, prevent the phenomenon of local overheating from occurring, and then make the cooling-down effect of bearing more obvious.
In the present invention one specific embodiment, bearing radiating ribs 1 is parallel to each other to be arranged in top surface.What bearing radiating ribs 1 was parallel is arranged in top surface, can the uniform heat radiation increasing bearing (ball) cover more comprehensively, ensures that the air circulation of every part of bearing (ball) cover is consistent, and then promotes the uniformity of bearing (ball) cover heat radiation.
In the present invention one specific embodiment, it is that emitting shape is vertical with top surface affixed that bearing radiating ribs 1 deviates from dead eye 2 direction by dead eye 2 court.Concrete, it is that emitting shape is arranged that bearing radiating ribs 1 can also deviate from dead eye 2 direction by dead eye 2 court, and affixed perpendicular to top surface.Setting like this, near bearing radiating ribs 1 comparatively edge's more crypto set at dead eye 2 place, therefore on the whole, the area that with air contact of bearing radiating ribs 1 near dead eye 2 place is larger, radiating effect is better, can further dispel the heat to the top surface at bearing place.
Based on the electric motor end cap that above-described embodiment provides, the present invention also provides a kind of motor, and motor comprises the electric motor end cap that above-described embodiment provides.
Because this motor have employed the electric motor end cap that above-described embodiment provides, therefore, the beneficial effect that this motor has electric motor end cap to bring please refer to above-described embodiment.
In the present invention one specific embodiment, the outside housing cover of motor body is provided with vertically the cover cap radiating ribs 4 reducing internal temperature.Concrete, the outside housing cover of motor body is provided with cover cap radiating ribs 4 vertically, cover cap radiating ribs 4 the heat that can reduce electric internal body is set, and then indirectly reduce the heat of bearing, extend the useful life of bearing and motor body.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
