Abstract
The utility model discloses an axial location structure of motor rotor, comprising a rotating shaft, an iron core disposed on the rotating shaft and a motor end cover, wherein an elastic sleeve with elasticity is disposed on the rotating shaft between a rotor and the motor end cover; one end of the elastic cover is pressed against the side wall of the iron core; the other end of the elastic sleeve is pressed against the side wall of the motor end cover. The axial location structure of motor rotor of the utility model is simply structured and conveniently used; the tiny elasticity of the elastic sleeve is used for locating the rotor axially and buffering the axial vibration; the rigid collision between the rotor and the motor end cover is avoided; the wear between the elastic sleeve and the motor end cover is reduced; and the service life and working efficiency of motor parts are improved.
Description
Technical field
The utility model relates to the axial positioning structure of micro-machine assembly, particularly a kind of rotor.
Background technology
For micro-machine, simple in structure, the axial location of rotor generally realizes by axle sleeve class part, in operation process, because moving axially of rotor is inevitable, and rigidity is bigger between rotor and the axle sleeve, may bump, produce noise, influence the operating efficiency of motor.
The utility model content
Problem to be solved in the utility model just provides a kind of axial positioning structure of rotor simple in structure, easy for installation, has avoided the generation of rigid collision, reduces noise, improves the useful life and the operating efficiency of motor part.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of axial positioning structure of rotor, comprise rotating shaft, be located at rotor core and electric motor end cap in the rotating shaft, it is characterized in that: in the rotating shaft between rotor and the electric motor end cap, be provided with the rubber-like resilient sleeve, one end of resilient sleeve is against on the sidewall of rotor core, and the other end of resilient sleeve is against on the madial wall of electric motor end cap.
Further, described resilient sleeve is horn-like, and the small end of resilient sleeve is against on the sidewall of rotor core, and the big end of resilient sleeve is against on the madial wall of electric motor end cap.
Further, be provided with sealing ring between described resilient sleeve and the electric motor end cap madial wall.
Further, the madial wall of described electric motor end cap is provided with the boss of location sealing ring.
After adopting technique scheme, the utlity model has following advantage: the micro-elastic of resilient sleeve is to the axial location and the buffering axial vibrations of rotor, avoided the rigid collision of rotor and electric motor end cap, the interaction energy of sealing ring is further controlled the end play of rotor and electric motor end cap, and reduces the wearing and tearing between resilient sleeve and the electric motor end cap.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
The structural representation of a kind of embodiment of the utility model as shown in Figure 1, a kind of axial positioning structure of rotor, comprise rotating shaft 1, be located at rotor core 2 and electric motor end cap 3 in the rotating shaft, in the rotating shaft between rotor and the electric motor end cap, be provided with rubber-like resilient sleeve 4, one end of resilient sleeve is against on the sidewall 21 of rotor core, and the other end of resilient sleeve is against on the madial wall 31 of electric motor end cap.
In the foregoing description, resilient sleeve is set as horn-like, the small end of resilient sleeve is against on the sidewall of rotor core, the big end of resilient sleeve is against on the madial wall of electric motor end cap, be provided with sealing ring 5 between resilient sleeve and the electric motor end cap madial wall, the madial wall of electric motor end cap is provided with the boss 32 of location sealing ring.Resilient sleeve can adopt plasticity preferred metal material to be made of such as copper.
The utility model is simple in structure, easy for installation, the micro-elastic of resilient sleeve is to the axial location and the buffering axial vibrations of rotor, avoided the rigid collision of rotor and electric motor end cap, the interaction energy of sealing ring is further controlled the end play of rotor and electric motor end cap, and the wearing and tearing between minimizing resilient sleeve and the electric motor end cap, the useful life and the operating efficiency of raising motor part.
Except that above preferred embodiment, the utility model also has other execution mode, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
