Description
Technical field
It the utility model is related to a kind of fan motor for automobile, and in particular to a kind of rotor axis of electric.
Background technology
The fan motor for automobile of the prior art, since the ventilation condition of motor internal is poor, heat caused by motor operation
It is not easy to discharge, so often being run under the operating condition of higher temperature, may have not only caused motor long-play to overheat, but also
It can make the easy aging of motor part and reduce motor service life.
The content of the invention
In view of the deficiency of background technology, the purpose of this utility model aims to provide a kind of the good logical of achievable motor internal
Wind, prevents motor long-play from overheating, and improves the split type rotor axis of electric of motor service life.
The utility model is adopted the following technical scheme that to complete：
Split type rotor axis of electric, equipped with axially extending bore, it is characterised in that：The armature spindle is divided into identical upper lower half
Axis, mutually at a distance from ventilation gap is formed between upper and lower semiaxis, the shaft end of upper and lower semiaxis is equipped with coupling sleeve, coupling sleeve
Upper and lower semiaxis is connected and fixed.
The coupling sleeve fixing sleeve is arranged on the shaft end of upper and lower semiaxis, the shaft end outer ring of the endoporus of coupling sleeve and upper and lower semiaxis
Into interference fit, the endoporus hole wall of coupling sleeve is equipped with the positioning convex strip for 180 degree setting of staggering, and the width of positioning convex strip is equal to up and down
The distance mutually left between semiaxis.
The axially extending bore is the small stepped hole in the big two stomidium footpath in interlude aperture, and dress is fixed in interlude axially extending bore
There is impeller, impeller is at least provided with two, and the one end for being arranged on interlude axially extending bore, another is arranged on interlude axially extending bore
The other end.
The rotor axis of electric of above-mentioned technical proposal, is divided into identical semiaxis up and down, one is mutually left between upper and lower semiaxis
Set a distance forms ventilation gap, can thus make the front and rear space of motor internal more preferably complete to penetrate through, to realize motor internal
Good ventilation provide necessary condition.Further, the aperture of the interlude axially extending bore of armature spindle is larger, and sets wherein
Impeller is put, when motor works, impeller is internally formed action of blast with armature spindle high-speed rotation in armature spindle, and then by upper
The ventilation gap of lower half between centers forms ventilation water conservancy diversion between space before and after motor internal, then realizes the good of motor internal
Ventilation, prevents motor long-play from overheating, and improves motor service life.
Preferably, the impeller has integrally formed blade and outer shroud, the cylindrical and interlude axially extending bore of outer shroud
Between be interference fitted.
