Description
Technical field
The utility model belongs to motor technology field, is related to a kind of threephase asynchronous.
Background technology
Make the threephase asynchronous machine of motor running, the rotating speed of its rotor is less than the rotating speed of rotating excitation field, rotor windings because
Relative motion is there is between magnetic field and electromotive force and electric current is produced, and produces electromagnetic torque with magnetic field interaction, realizes energy
Change of variable, compared with monopole asynchronous motor, threephase asynchronous runnability is good, and can save various materials.In order to increase
Power up the heat dispersion of motivation, end is generally fitted with radiator fan behind, its current radiator fan typically with motor shaft all
It is coaxially connected, the maintenance that the attachment structure is easily caused the motor later stage is inconvenient.
The content of the invention
The purpose of this utility model be for the above-mentioned problems in the prior art there is provided one kind it is simple in construction and
Facilitate the threephase asynchronous of later period maintenance.
The purpose of this utility model can be realized by following technical proposal：A kind of threephase asynchronous, including fuselage
With the power transmission shaft being arranged in fuselage, the outer surface of the fuselage is uniformly provided with some dissipation backings, the fuselage
Side is provided with the base being fixedly connected with it, it is characterised in that the outwardly formation integrative-structure of rearward end of the power transmission shaft
Connecting key and it is provided with by connecting key close-fitting on axle sleeve, described axle sleeve and offers keyway, the rear end of the fuselage passes through
Screw, which is fixed between cover plate and cover plate and fuselage, is provided with bearing, and described axle sleeve stretches out outside cover plate and is provided with by keyway
Fan, is fixed between described fan and axle sleeve by snap ring.
The technique effect of this threephase asynchronous is：Relative to the power transmission shaft of conventional three-phase asynchronous motor, this is electronic
The outwardly connecting key for forming integrative-structure of the rearward end of machine power transmission shaft and axle sleeve is provided with by connecting key close-fitting, quite
In being split as two-part structure, and fan is installed on axle sleeve by snap ring, the power needed for being rotated due to fan
It is smaller to can be ignored, thus segmentation structure can't influence motor be driven stability, when later stage motor shaft rear end with
When being worn and torn between bearing, without by whole dismounting of motor shaft, axle sleeve need to only be changed, facilitate the motor later stage
Maintenance.
In a kind of above-mentioned threephase asynchronous, protection fan has been provided with by radial direction screw on described cover plate
The protective cover of effect.
In a kind of above-mentioned threephase asynchronous, the sectional area of the connecting key is regular hexagon structure.
In a kind of above-mentioned threephase asynchronous, packing ring is installed between fan on described cover plate.
Compared with prior art, this threephase asynchronous by transmission shaft rear end by being designed to the segmented side of making it have
Just the advantage of detachable maintaining.

The outwardly connecting key 5 and being provided with by the close-fitting of connecting key 5 on axle sleeve 6, axle sleeve 6 for forming integrative-structure of rearward end open
Provided with keyway 7, the rear end of fuselage 1 is fixed between cover plate 8 and cover plate 8 and fuselage 1 by screw is provided with bearing 9, and axle sleeve 6 is stretched
Go out outside cover plate 8 and fan 10 is provided with by keyway 7, fixed between fan 10 and axle sleeve 6 by snap ring.
Further describe in detail, the protective cover 11 that protection fan 10 is acted on, connecting key have been provided with by radial direction screw on cover plate 8
5 sectional area is to be provided with packing ring 12 between fan 10 on regular hexagon structure, cover plate 8.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although more used herein fuselage 1, power transmission shaft 2, fin 3, base 4, connecting key 5, axle sleeve 6, keyway 7,
The terms such as cover plate 8, bearing 9, fan 10, protective cover 11, packing ring 12, but it is not precluded from the possibility using other terms.Use
These terms are used for the purpose of more easily describing and explaining essence of the present utility model；It is construed as any additional
Limitation all disagreed with the utility model spirit.
