Description
Technical field
the utility model relates to a kind of washing machine motor rotor, particularly a kind of washing machine motor rotor with mute function.
Background technology
along with the development of washing machine, people require that the noise produced in washing machine running is the smaller the better.In the market for the rotor of motor for washer be generally that one deck rubber shock-absorbing layer is set between internal rotor and external rotor, reduce the vibrations of rotor, thus reduce the noise that produces in washing machine running.But the rubber shock-absorbing layer in this rotor easily comes off from internal rotor and external rotor surface, thus make internal rotor, exist between external rotor and rubber shock-absorbing layer and relatively rotate, affect damping effect and motor normally works.Meanwhile, because the deformation of rubber shock-absorbing layer is comparatively large, the concentricity of internal rotor and external rotor can be made to occur larger situation, affect motor and normally work.Therefore, existing washing machine motor rotor also exists rubber shock-absorbing layer and more easily comes off, the undesirable and easy problem affecting machine operation of damping effect.
Utility model content
the purpose of this utility model is, provides a kind of washing machine motor rotor with mute function.The utility model can not only prevent rubber shock-absorbing pull-up from falling, and guarantees that motor normally works, and also has the advantage of good damping effect.
the technical solution of the utility model: a kind of washing machine motor rotor with mute function, comprises internal rotor, and internal rotor arranged outside has external rotor; The outer surface of internal rotor is provided with some radially outer male part, and the inner surface of external rotor is provided with some radially inner interior protuberances, there is certain space between adjacent male part and interior protuberance; External rotor outer surface is connected with equally distributed permanent magnet, between adjacent two pieces of permanent magnets, is provided with PBT Connection Block; Be provided with the rubber shock-absorbing layer of ring-type between internal rotor and external rotor, in rubber shock-absorbing layer, be provided with some sound-absorption hole, the inner surface of rubber shock-absorbing layer and outer surface are equipped with some grooves.
aforesaid a kind ofly have in the washing machine motor rotor of mute function, and the middle part on described internal rotor and surface, the external rotor left and right sides is provided with the mounting groove of ring-type, mounting groove is provided with PBT Connection Block; The PBT Connection Block of adjacent two pieces of permanent magnets is fixedly connected on the outer surface of external rotor.
aforesaid a kind ofly have in the washing machine motor rotor of mute function, and the groove on the described inside and outside surface of rubber shock-absorbing layer is connected with male part and interior protuberance respectively, and the length of male part and interior protuberance is all less than the thickness of rubber shock-absorbing layer.
compared with prior art, the utility model improves the structure of rotor, by arranging interior protuberance, male part and groove, adding rubber shock-absorbing layer and the contact area between external rotor and internal rotor, strengthening rubber shock-absorbing layer, connection between external rotor and internal rotor.Meanwhile, the utility model is also provided with PBT Connection Block, and the connection between permanent magnet and external rotor can be strengthened and guarantee to the PBT Connection Block on external rotor outer surface; PBT Connection Block in external rotor and internal rotor both side surface can not only limit the axial location of rubber shock-absorbing layer, can also strengthen overall construction intensity, guarantees that the concentricity of internal rotor and external rotor is in a stable normal range (NR).And, be provided with some suction holes in rubber shock-absorbing layer of the present utility model, by while the damping noise reduction of rubber shock-absorbing layer, also absorb noise by suction hole, substantially increase muting function.Therefore, the utility model can not only prevent rubber shock-absorbing pull-up from falling, and guarantees that motor normally works, and also has good damping effect and the good advantage of muting function.
