Abstract
Disclosed is a motor fixing device of fully enclosed compressor, comprising a drive motor, a compression pump body and a housing in which the drive motor and the compression pump body are arranged, and characterized in that the motor fixing device further comprises a backing ring between a stator of the drive motor and the housing; the internal diameter of the backing ring forms interference fit and shrinkage fit with the external diameter of the stator of the drive motor; and the external diameter of the backing ring forms interference fit and shrinkage fit with the internal diameter of the housing. The motor fixing device of compressor can reduce motor vibration and noise, facilitate the cooling of the drive motor when the compressor is operated, and bring about convenience for producing and assembling.
Description
Technical field
The utility model relates to technical field of refrigeration compressors, particularly the motor technique for fixing of compressor.
Background technology
In general; The compressor of prior art all has the compression pump housing with an electric rotating machine and be connected motor and the rotating shaft of the pump housing; The three is fixed in a totally enclosed enclosure interior; Fixing between motor stator and the housing, the rotor rotation drives pump body compression, and motor stator external diameter and housing internal diameter interference fit are installed together usually.The deficiency of prior art is: vibration and noise that motor produces can be directly conducted on the housing, conduct to the external world then, and be especially more obvious for the uneven motor of some Distribution of Magnetic Field; Motor in the totally-enclosed compressor mainly relies on the gas flow cooling, because the volume requirement of motor stator, the gas passage cross-sectional area is restricted between the motor top and bottom.
Summary of the invention
The purpose of the utility model provides a kind of motor fixing device of fully closed compressor, the motor oscillating and the noise that are transmitted on the housing is reduced, and help the motor cooling.
The technical scheme of the utility model is: a kind of motor fixing device of fully closed compressor; Comprise drive motors, the compression pump housing and housing; Drive motors places in the housing with the compression pump housing, it is characterized in that said fixture also comprises grommet, and said grommet is located between drive motors stator and the housing; For the interference hot charging cooperates, cooperate for the interference hot charging between the external diameter of grommet and the housing internal diameter between the internal diameter of said grommet and the motor stator external diameter.
The inner surface and the outer surface of said grommet have groove, and groove is an axial groove, the perhaps mixing groove that combines of axial groove and circumferential grooves, and axial groove connects the upper surface and the lower surface of grommet, and circumferential grooves is offered along the grommet circumference.
The axial groove on the inside and outside surface of said grommet is 1-8, and the circumferential grooves on the inside and outside surface of said grommet is 1-3.
The inner surface of said grommet and the gash depth of outer surface are 1-10mm.
Said grommet material is a metal or nonmetal.
The beneficial effect of the utility model is:
1, has the groove grommet, when compressor operation, can increase near the refrigerant circulation of motor, the heating of controlling and driving motor body, the long-term operation reliability of increase compressor.
2, grommet is between drive motors stator and compressor case, and vibration and noise section that drive motors is produced are cushioned by grommet, reduces to be transmitted to extraneous noise.
3, the axial and circumferential groove of the inside and outside both sides of grommet can reduce the contact area of grommet and shell, is convenient to the hot charging shell.
Description of drawings
The utility model has accompanying drawing 3 width of cloth, wherein
Fig. 1 is the structural representation of the motor fixing device of the utility model fully closed compressor,
Fig. 2 is the grommet sketch map with axial groove;
Fig. 3 is the grommet sketch map with axial groove and circumferential grooves combination;
Among the figure: 1, motor 2, housing 3, grommet
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment 1 is the embodiment that grommet has axial groove.The axial groove of grommet is four, and the degree of depth of groove is 2mm, and the grommet material is a metal material.Drive motors 1 places in the housing 2 with the compression pump housing; The grommet 3 that has axial groove is located between drive motors stator and the housing 2; For the interference hot charging cooperates, cooperate for the interference hot charging between the external diameter of grommet 3 and housing 2 internal diameters between the internal diameter of grommet 3 and the motor stator external diameter.Earlier being installed together grommet internal diameter and motor stator external diameter interference fit during assembling, being heated to high temperature to housing then, is to be installed in the grommet outside under the ambient temperature at grommet.
Embodiment 2 is embodiment that grommet has axial groove and circumferential grooves combination.The axial groove of grommet is four, and circumferential grooves is one, and the degree of depth of groove is 2mm, and the grommet material is plastics.Drive motors 1 places in the housing 2 with the compression pump housing; The grommet 3 that has axial groove is located between drive motors stator and the housing 2; For the interference hot charging cooperates, cooperate for the interference hot charging between the external diameter of grommet 3 and housing 2 internal diameters between the internal diameter of grommet 3 and the motor stator external diameter.Earlier being installed together grommet internal diameter and motor stator external diameter interference fit during assembling, being heated to high temperature to housing then, is to be installed in the grommet outside under the ambient temperature at grommet.
