Abstract
The utility model discloses a kind of compressing structures 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, further include screw rod, nut, tetrafluoro cushion block and pressure ring, in the tetrafluoro cushion block and the coaxial casing of pressure ring, and tetrafluoro cushion block is located at the top of pressure ring, screw rod is plugged in along the axial direction of stator on 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 inner wall of casing.The tetrafluoro cushion block of the utility model has certain elastic deformation amount, rigid contact before being avoided relatively in the nut and casing of screw rod upper end becomes 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 utility model is related to a kind of compressing structures of motor stator.
Background technology：
The installation of the motor stator of existing wind turbine be by motor cabinet /V, but after Stator and electrical machine seat installs,
Because the linear dimension of stator and engine base is plus tolerance on axial direction, and installs the axial linear of the chassis hole of stator and engine base
Size is negative common difference, and the installation end face of actual upper frame and casing is discontiguous there are gap.If engine base during mounting screw
End face one side and chassis contact, opposite side will tilt, this can cause the installation of engine base to be inclined, and actual installation is to installation
The concentricity requirement of parts is higher, it is clear that this is to generate certain influence.
Utility model content：
The utility model is to provide a kind of compression knot of motor stator to solve the above-mentioned problems of the prior art
Structure.
There is technical solution used by the utility model：A kind of compressing structure of motor stator, including stator, casing and electricity
Engine base, the stator are placed in casing, and motor cabinet is fixed at the lower port of casing, further include screw rod, nut, tetrafluoro cushion block and
Pressure ring, in the tetrafluoro cushion block and the coaxial casing of pressure ring, and tetrafluoro cushion block is located at the top of pressure ring, axial direction side of the screw rod along stator
To being 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
It contacts 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 machine by pressure ring
On the inner wall of shell.
Further, the inner wall of the casing lower port is equipped with positioning step portion.
Further, the motor cabinet is equipped with the boss portion that the positioning step portion is adapted.
The utility model has the advantages that：The tetrafluoro cushion block of the utility model has certain elastic deformation amount,
Rigid contact before being avoided relatively in the nut and casing of screw rod upper end becomes Elastic Contact, therefore can effectively ensure motor
Close contact between seat and casing ensures the concentricity requirement of each installing component.
Description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the matching chart between casing and motor cabinet in the utility model.
Fig. 3 is the structure chart of motor cabinet in the utility model.
Specific embodiment：
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1 to Figure 3, the utility model discloses a kind of compressing structure of motor stator, including stator 11, casing
12nd, motor cabinet 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
At the lower port of casing 12, tetrafluoro cushion block 16 and pressure ring 17 are arranged in casing 12, and tetrafluoro cushion block 16, pressure ring 17 and stator 11
Coaxial arrangement, tetrafluoro cushion block 16 are located at the top of pressure ring 17.The axial direction of screw rod 14 along stator 11 is plugged on stator 11, spiral shell
The upper/lower terminal of bar 14 is threadedly coupled a nut 15 respectively, and nut 15 is by 11 axially position of stator.Motor cabinet 13 is consolidated by screw
At the lower port of casing 12, and motor cabinet 13 is contacted on the nut of 14 lower end of screw rod, and by the nut of 14 upper end of screw rod
It contacts on pressure ring 17, pressure ring 17 contacts at tetrafluoro cushion block 16 on the inner wall of casing 12.
The utility model is ensures the effect that is located by connecting good between casing 12 and motor cabinet 13, in 12 lower port of casing
Inner wall is equipped with positioning step portion 121, corresponds ground, is adapted on motor cabinet 13 equipped with the positioning step portion 121
Boss portion 131.
It is partially soft for 16 opposing metallic of tetrafluoro cushion block in the utility model, but have certain flexible deformation.When stator 11
After having good positioning, 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 flexible deformation occurs.Pressure ring 17 can ensure that the compression of tetrafluoro cushion block 16 is uniform.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, several improvement can also be made on the premise of the utility model is not departed from, these improvement also should be regarded as this reality
With new protection domain.
