Description
Technical field
This utility model relates to motor technology field, the motor of a kind of band overload protection arrangement.
Background technology
Motor is a kind of equipment converting electrical current into into mechanical energy.It is to use the power on coil produce rotating excitation field and make
Electro-magnetic motor force rotation torque is formed for rotor.The coil of motor is typically to be coiled into by the thinnest copper wire, the ability of resistance to electric current
Poor.When motor load is relatively big or motor blocks, the electric current flowing through coil can quickly increase, and motor temperature drastically rises simultaneously
Height, copper wire winding is easily burned out.Therefore people concatenate macromolecular PTC thermistor in motor winding, then can be at motor
Provide protection against during overload, it is to avoid motor is burned out.But in the commercial production of some heavy currents, of short duration overload is just
Likely motor coil is caused destructive destruction, and thermorelay is to utilize critesistor heating to blow to make electric motor circuit breaking
Thus protect motor, it is therefore desirable to the regular hour could power-off, protection not in time, reliability is low.
Utility model content
The purpose of this utility model is to provide the motor of a kind of band overload protection arrangement, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of motor of band overload protection arrangement, including: motor, belt wheel, power transmission shaft, flat key, outer reducing sleeve, interior turn
Female connector, woodruff key and spring, described interior reducing sleeve and outer reducing sleeve are cylindrical shape, and interior reducing sleeve excircle has A keyway,
Fixing spring bottom described A keyway, the spring other end fixes woodruff key, and described outer reducing sleeve inwall has B keyway, described B key
Groove size and A keyway consistent size on interior reducing sleeve.
As further program of the utility model: described interior reducing sleeve inwall has C keyway, described outer reducing sleeve cylindrical
Having D keyway on week, install flat key in described C keyway, interior reducing sleeve is arranged on power transmission shaft by flat key, in described D keyway
Installing flat key, described belt wheel is arranged on outer reducing sleeve by flat key.
As this utility model further scheme: described woodruff key spring be former long time depart from B keyway.
Compared with prior art, the beneficial effects of the utility model are: compare existing fusing by thermorelay and prevent electricity
The mode of dynamic overload, this utility model reaction base is timely rapidly, and reliability is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the motor of a kind of band overload protection arrangement.
Fig. 2 is the interior reducing sleeve structural representation with outer reducing sleeve of the motor of a kind of band overload protection arrangement.
Fig. 3 be a kind of band overload protection arrangement motor spring former long time woodruff key position structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, in this utility model embodiment, the motor of a kind of band overload protection arrangement, including: motor
2, belt wheel 1, power transmission shaft 4, flat key 3, outer reducing sleeve 6, interior reducing sleeve 5, woodruff key 7 and spring 9, described interior reducing sleeve 5 is with outer
Reducing sleeve 6 is cylindrical shape, interior reducing sleeve 5 excircle has A keyway 10, fixes spring 9 bottom described A keyway 10, and spring 9 is another
Woodruff key 7 is fixed in one end, and described outer reducing sleeve 6 inwall has B keyway 8, described B keyway 8 size and A keyway on interior reducing sleeve 5
10 consistent size, when motor 2 starts, power transmission shaft 4 drives interior reducing sleeve 5 to rotate, receive centrifugal action due to woodruff key 7 and
Away from A keyway 10, until woodruff key 7 enters B keyway 8, outer reducing sleeve 6 is driven to rotate；When motor 2 occurs overload rotating speed rapid
Declining, the centrifugal force that woodruff key 7 is subject to reduces, spring 9 pull and depart from B keyway 8, such power transmission shaft 4 no longer band dynamic load,
Motor 2 starts idle running, avoids overload timely.
Described interior reducing sleeve 5 inwall has C keyway 11, and described outer reducing sleeve 6 excircle has D keyway 12, described C key
Installing flat key 32 in groove 11, interior reducing sleeve 5 is arranged on power transmission shaft 4 by flat key 32, installs flat key 31 in described D keyway 12,
Described belt wheel 1 is arranged on outer reducing sleeve 6 by flat key 31.
Described woodruff key 7 spring 9 be former long time depart from B keyway 8, do not work or rotating speed is relatively low at motor 2
Time, interior reducing sleeve 5 should not drive outer reducing sleeve 6 to rotate.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
