Description
Technical field
the utility model relates to a kind of rotor.
Background technology
the rotor be generally used in external rotor electric machine is one-body molded often, and rotor is made up of the aluminium that material is lighter, because aluminium is comparatively soft, make the bonding strength between rotating shaft and rotor poor, for this situation, existing external rotor electric machine adds the better steel bushing of rigidity between rotor and rotating shaft, in the course of the work, steel bushing relative rotor often produces relative rotation or displacement axially, rotor is easily damaged, useful life is shorter.
Utility model content
the purpose of this utility model is to provide stable connection between a kind of rotor body and rotor body, the rotor that substantially can not produce relative rotation or move to axial.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of rotor, for external rotor electric machine, described external rotor electric machine comprises internal stator, one end fits is arranged on the rotating shaft on described internal stator, be fixedly mounted on the described rotor on the described rotating shaft other end, described rotor comprises the rotor body that inside offers cavity, be located at the rotor body for the fixing described rotating shaft other end in described cavity, described rotor body outer peripheral face is provided with lug boss along its axially spaced-apart, the concave part coordinating described lug boss correspondence to insert is provided with in described cavity, described rotor body, described rotor body respectively with the setting of described rotating shaft coaxial inner conductor.
preferably, the radial section of described lug boss is non-circular.
preferably, the radial section of described rotor body inner surface is circular, and described rotating shaft one end is fixedly located in described rotor body.
preferably, the outer surface of described rotor body is circumferentially spacedly provided with the first reinforcement along it.
preferably, circumferentially spacedly the second reinforcement is provided with along it in described cavity.
preferably, in described cavity, be provided with the fixed part for fixing described rotor body, be provided with the described concave part coordinating described lug boss correspondence to insert in described fixed part, the setting of described fixed part and described rotor body coaxial inner conductor.
more preferably, described fixed part outer surface is circumferentially spacedly provided with the 3rd reinforcement along it.
due to the utilization of technique scheme, the utility model compared with prior art has following advantages: the utility model is by being provided with lug boss spaced apart vertically at rotor body outer peripheral face, the concave part coordinating this lug boss correspondence to insert is set in rotor body, the movement produced between rotor body and rotor body axially can be avoided, the radial section of this lug boss is non-circular simultaneously, can avoid producing relative rotation between rotor body and rotor body, make rotor not fragile, extend its useful life.

Embodiment
below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
shown in Fig. 1-4, above-mentioned a kind of rotor, for external rotor electric machine, this external rotor electric machine comprises internal stator, one end fits is arranged on the rotating shaft 3 on internal stator, the rotor be fixedly mounted on this rotating shaft 3 other end.
this rotor comprises the rotor body 1 that inside offers cavity 11, be located at the rotor body 2 for fixed rotating shaft 3 other end in cavity 11, rotating shaft 3 is fixedly located in this rotor body 2, the setting of rotating shaft 3 and rotor body 2 coaxial inner conductor, this rotor body 2 outer peripheral face is provided with the identical multiple lug bosses 21 of shape uniformly along its axially spaced-apart, be provided with in cavity 11 and coordinate multiple lug boss 21 corresponding multiple concave parts 13 inserted respectively, by the setting of this lug boss 21 with concave part 13, rotor body 1 and rotor body 2 are fixedly connected and can not produce relative movement axially, the setting of this rotor body 1 and this rotor body 2 coaxial inner conductor, in this example, rotor body 1 is made up of aluminium, rotor overlaps 2 bodies and is made up of stainless steel.
in the present embodiment, the fixed part 12 for fixed rotor body 2 is also provided with in cavity 11, be provided with in this fixed part 12 and coordinate multiple lug boss 21 corresponding multiple concave parts 13 inserted respectively, the outer surface of this fixed part 12 is provided with multiple 3rd reinforcement 6 uniformly along its circumferential interval, by the setting of the 3rd reinforcement 6, add the constant intensity of rotor body 2, increase its useful life.
the radial section of above-mentioned lug boss 21 is non-circular, by this non-circular setting, can avoid at work, relatively rotate between rotor body 1 and rotor body 2, and in the present embodiment, the radial section of lug boss 21 is regular hexagon.
in order to increase the constant intensity of rotor body 1 to increase its useful life, the outer surface of this rotor body 1 is provided with multiple first reinforcement 4 uniformly along the upper interval of its circumference, is provided with multiple second reinforcement 5 uniformly in cavity 11 along the upper interval of its circumference simultaneously.
above-mentioned rotor body 1 and rotor body 2 use bi-material to build stripping forming simultaneously, afterwards one end of rotating shaft 3 to be penetrated in this rotor body 2 and to make it relatively fixing, during use, on the internal stator being arranged in external rotor electric machine that only other end of rotating shaft 2 need be coordinated.
