Utility model content
The purpose of this utility model is in casing deformation and temperature in providing one kind and can reduce motor operation course The vibration reduction electric machine of vibration noise caused by change.
In order to reach the purpose, the utility model adopts the following technical scheme that:Including support, shell, drive end bearing bracket and rear end Lid, rotating shaft is provided with through the drive end bearing bracket and the rear end cap, and rotor is provided with the rotating shaft, is surround between the shell described Rotor is provided with stator, it is characterised in that:Also include supporting arrangement, the supporting arrangement includes being socketed in the outer side Fixed cylinder and the support on the outside of the fixed cylinder, the fixed cylinder inner side are provided with supporting close to the support side Body, the supporting mass include the contact site being bonded with the outer side surface and positioned at the contact sites and the fixed cylinder Between support, relatively described supporting mass is provided with limit body, the limit body bag between the fixed cylinder and the shell Include the elastic spacing portion contacted with shell and the power transmission portion between the elastic spacing portion and the fixed cylinder, the elasticity The contact surface of limiting section and the shell is provided with inner concave, and the section of the inner concave is circular arc.
Thus, in the motor course of work, the motor feels hot or ambient temperature rise and motor movement or structure suction In the case of thermal deformation, in elastic spacing portion, stress deformation, inner concave heat absorption expand, the contact area of elastic spacing portion and shell Increase and the load between the two becomes big.
As a preferred embodiment, the position-limiting drum is fixedly installed fan housing, the fan housing and institute close to the rear end cap side State and be connected with fan in the rotating shaft between rear end cap.
Thus, the heat that motor housing sheds is discharged, avoids too high element manipulation and the shell of influenceing of heat Deformation.
As a preferred embodiment, the contact site, the elastic spacing portion form the cavity of both ends open with the position-limiting drum.
Thus, air circulates by the cavity.
As a preferred embodiment, it is uniformly provided with heat emission hole on the contact site.
Thus, avoid shell local temperature too high.
As a preferred embodiment, the quantity of the limit body is two, two elastic spacing portions are on the support It is symmetrical arranged.
Thereby it is ensured that the stability of structure.
As a preferred embodiment, the power transmission portion is provided with contiguous block with the fixed cylinder.
As a preferred embodiment, the inner concave is uniformly distributed along in the shell circumference.
To sum up, the utility model has advantages below:Motor oscillating can be effectively reduced, it is simple and reliable for structure.
