A kind of damping rotor structure, comprise internal layer iron core, outer iron core and middle buffer layer, internal layer iron core and outer iron core connect by middle buffer layer, the outer side surface of internal layer iron core is established some outer grooves, the interior sidewall surface of outer iron core is established some inner groovies, outer groove and inner groovy position are corresponding, and the projection that protrude middle buffer layer both sides embeds respectively in outer groove and inner groovy, and the fixture block that protrude at middle buffer layer two ends is buckled in respectively on the end face and bottom surface of internal layer iron core and outer iron core.

The outer side surface of outer iron core described above protrudes some axial location muscle, between adjacent two positioning bars, outer iron core outer side surface installs permanent magnet.

Middle buffer layer described above is the elastomeric material injection mo(u)lding.

Middle buffer layer described above is that rubber is made.

Internal layer iron core and rotating shaft described above connect.

Outer groove described above is deep-slotted chip breaker, and inner groovy is deep-slotted chip breaker.

The utility model beneficial effect compared with prior art is: 1) outer side surface of the utility model internal layer iron core is established some outer grooves, the interior sidewall surface of outer iron core is established some inner groovies, outer groove and inner groovy position are corresponding, the projection that protrude middle buffer layer both sides embeds respectively in outer groove and inner groovy, realize the radial location assembling, the fixture block that protrude at middle buffer layer two ends is buckled in respectively on the end face and bottom surface of internal layer iron core and outer iron core, realize the axial location assembling, simple in structure, be connected firmly, good damping effect reduces noise; 2) outer side surface of outer iron core protrudes some axial location muscle, and between adjacent two positioning bars, outer iron core outer side surface installs permanent magnet, permanent magnet is installed simple and easy by the positioning bar location and installation; 3) in the middle of, buffer layer is the elastomeric material injection mo(u)lding, and middle buffer layer is that rubber is made, and is with low cost, good damping effect.
