Abstract
The utility model provides an electric motor rotor shock -absorbing structure belongs to the motor field, it has solved the problem that the yielding rubber easily misplaced among the current electric motor rotor shock -absorbing structure. The utility model discloses an outer rotor core with establish the inboard interior rotor core at outer rotor core, it has the yielding rubber to fill between outer rotor core and the interior rotor core, pastes on the outer rotor core outer wall and installs a plurality of permanent magnets, interior rotor core outer wall encircles that to be equipped with a plurality of bars protruding, outer rotor core inner wall is equipped with the recess that corresponds with the arch, arch and the groove phase setting of standing erect, and be equipped with the yielding rubber between arch and the recess. The setting because the protruding groove phase with outer rotor core inner wall of interior rotor core outer wall stands erect, and be equipped with the yielding rubber between arch and the recess, therefore firmly block the yielding rubber through arch and recess, preventing its dislocation, can increase and yielding rubber area of contact through protruding and recess simultaneously for the shock attenuation effect is better.
Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of rotor shock-damping structure.
Background technology
Existing motor shock absorption rotor comprises internal rotor iron core and outer rotor iron core, outer rotor iron core to be enclosed within outside internal rotor iron core and to form space between outer rotor iron core and internal rotor iron core, the outside wall surface of internal rotor iron core stretches out some interior protuberances, the internal face of outer rotor iron core stretches out some male part, interior protuberance and male part be relative or spaced arrangement between two, insulator is provided with between outer rotor iron core and internal rotor iron core, but the insulator of the damping rotor of this structure easily and internal rotor iron core or outer rotor iron core mutual dislocation, the concentricity of rotor is caused to control poor, affect the operational efficiency of rotor.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of good damping effect and prevents yielding rubber from misplacing, and can also increase the rotor shock-damping structure of thermal diffusivity.
The purpose of this utility model realizes by following technical proposal: a kind of rotor shock-damping structure, comprise outer rotor iron core and be located at the internal rotor iron core inside outer rotor iron core, yielding rubber is filled with between described outer rotor iron core and internal rotor iron core, outer rotor iron core outer wall is pasted some permanent magnets are installed, it is characterized in that: internal rotor iron core outer wall is around being provided with some strip bulges, outer rotor iron core inwall is provided with the groove corresponding with projection, described projection and groove stand erect setting mutually, and are provided with yielding rubber between described projection and groove.
Because the projection of internal rotor iron core outer wall and the groove of outer rotor iron core inwall stand erect setting mutually, and be provided with yielding rubber between projection and groove, therefore firmly yielding rubber is blocked by protruding and groove, prevent it from misplacing, can be increased and yielding rubber contact area by protruding and groove simultaneously, make damping effect better.
As preferably, described projection is V-shaped, and groove is the V-shaped groove corresponding with projection.
As preferably, described lobed interior has the bar shaped heat radiation cavity of both ends open.
As preferably, in described heat radiation cavity, be provided with fin.
Radiating effect when heat radiation cavity and fin can improve rotor turns is set.
As preferably, outer rotor iron core inner wall section and internal rotor iron core outer wall cross section are circle, and outer rotor iron core inwall is provided with and bar shaped boss, and described groove is located on boss.
Therefore more yielding rubber can be set between outer rotor iron core inwall and internal rotor iron core outer wall.
As preferably, described yielding rubber is injection mo(u)lding.
Therefore yielding rubber can be filled up between outer rotor iron core inwall and internal rotor iron core outer wall.
Compared with prior art, the utility model tool has the following advantages:
Because the projection of internal rotor iron core outer wall and the groove of outer rotor iron core inwall stand erect setting mutually, and be provided with yielding rubber between projection and groove, therefore firmly yielding rubber is blocked by protruding and groove, prevent it from misplacing, can be increased and yielding rubber contact area by protruding and groove simultaneously, make damping effect better.
