Abstract
The invention discloses a kind of compressing structure of motor stator, including stator, casing and motor cabinet, the stator is placed in casing, motor cabinet is fixed at the lower port of casing, also include screw rod, nut, tetrafluoro cushion block and pressure ring, in the coaxial casing of the tetrafluoro cushion block and pressure ring, and tetrafluoro cushion block is located at the top of pressure ring, screw rod is plugged on stator along the axial direction of stator, screw rod it is upper, lower both ends are threadedly coupled a nut respectively, motor cabinet is fixed on casing, and motor cabinet is contacted on the nut of screw rod lower end, and the nut of screw rod upper end is contacted on pressure ring, pressure ring contacts at tetrafluoro cushion block on the inwall of casing.The tetrafluoro cushion block of the present invention has certain elastic deformation amount, rigid contact before being avoided relatively in the nut and casing of screw rod upper end is changed into Elastic Contact, therefore it can effectively ensure the close contact between motor cabinet and casing, ensure the concentricity requirement of each installing component.
Description
Technical field：
The present invention relates to a kind of compressing structure of motor stator.
Background technology：
The installation of the motor stator of existing blower fan is spacing by motor cabinet, but after Stator and electrical machine seat installs,
Because the linear dimension of stator and support is plus tolerance on axial direction, and installs the axial linear of the chassis hole of stator and support
Size is negative common difference, and the installation end face of actual upper frame and casing is that gap to be present discontiguous.If support during mounting screw
End face side and chassis contact, opposite side will tilt, and this can cause the installation of support to be inclined, and actual installation is to installation
The concentricity requirement of parts is higher, it is clear that this is to produce certain influence.
The content of the invention：
The present invention is to provide a kind of compressing structure of motor stator to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：A kind of compressing structure of motor stator, including stator, casing and motor
Seat, the stator are placed in casing, and motor cabinet is fixed at the lower port of casing, in addition to screw rod, nut, tetrafluoro cushion block and pressure
Ring, in the coaxial casing of the tetrafluoro cushion block and pressure ring, and tetrafluoro cushion block is located at the top of pressure ring, axial direction of the screw rod along stator
It is plugged on stator, the upper/lower terminal of screw rod is threadedly coupled a nut respectively, and motor cabinet is fixed on casing, and motor cabinet supports
Touch on the nut of screw rod lower end, and the nut of screw rod upper end is contacted on pressure ring, tetrafluoro cushion block is contacted at casing by pressure ring
Inwall on.
Further, the inwall of the casing lower port is provided with positioning step portion.
Further, the motor cabinet is provided with the boss portion that the positioning step portion is adapted.
The present invention has the advantages that：The tetrafluoro cushion block of the present invention has certain elastic deformation amount, screw rod upper end
Nut and casing in avoid relatively before rigid contact be changed into Elastic Contact, therefore can effectively ensure motor cabinet and casing
Between close contact, ensure the concentricity requirement of each installing component.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 is the matching chart between casing and motor cabinet in the present invention.
Fig. 3 is the structure chart of motor cabinet in the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the present invention discloses a kind of compressing structure of motor stator, including stator 11, casing 12, electricity
Support 13, screw rod 14, nut 15, tetrafluoro cushion block 16 and pressure ring 17, stator 11 are placed in casing 12, and motor cabinet 13 is fixed on casing
At 12 lower port, tetrafluoro cushion block 16 and pressure ring 17 are in casing 12, and tetrafluoro cushion block 16, pressure ring 17 and stator 11 are coaxially set
Put, tetrafluoro cushion block 16 is located at the top of pressure ring 17.Axial direction of the screw rod 14 along stator 11 is plugged on stator 11, screw rod 14
Upper/lower terminal is threadedly coupled a nut 15 respectively, and nut 15 is by the axially position of stator 11.Motor cabinet 13 is fixed on machine by screw
At the lower port of shell 12, and motor cabinet 13 is contacted on the nut of the lower end of screw rod 14, and the nut of the upper end of screw rod 14 is contacted at
On pressure ring 17, pressure ring 17 contacts at tetrafluoro cushion block 16 on the inwall of casing 12.
The present invention is ensures the effect that is located by connecting good between casing 12 and motor cabinet 13, in the inwall of the lower port of casing 12
Positioning step portion 121 is provided with, corresponds ground, is adapted on motor cabinet 13 provided with the positioning step portion 121 convex
Platform portion 131.
It is partially soft for the opposing metallic of tetrafluoro cushion block 16 in the present invention, but have certain elastic deformation.When stator 11 positions
After good, then when installing motor cabinet 13, the nut 15 on screw rod 14 is compacted, the end contact of motor cabinet 13 and casing 12, tetrafluoro
Cushion block 16, which compresses, to be shunk, and elastic deformation occurs.Pressure ring 17 can ensure that the compression of tetrafluoro cushion block 16 is uniform.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise of not departing from the present invention, and these improvement also should be regarded as the protection of the present invention
