Description
Technical field
The utility model belongs to box type electrical machine technical field, especially a kind of box type electrical machine tilting upper end cover structure.
Background technology
In existing technology, for box type electrical machine, in order to protect motor stator winding overhang injury-free, again
The requirement of motor ventilation heat dissipation can be reached, therefore, the architectural characteristic of box type electrical machine keeps its volume larger, and for current box electricity
The trend that machine develops to enlargement, in design and manufacture, in order to ensure the heat-dissipating space for having enough inside motor, axial dimension
Also it needs constantly to increase, in this way, the bearing capacity of engine base will necessarily reduce, directly influences the service life of motor, in addition, due to
The increase of rotor length not only increases the design difficulty of rotor dynamics, and increases the design and cost of manufacture of motor.
Therefore reduce the axial dimension of engine base and rotor is just particularly important for large box type motor.
Utility model content
The purpose of this utility model is to provide a kind of heat dissipation area that can increase inside motor and shortens rotor axial
The box type electrical machine tilting upper end cover structure of length.
Technical solution is used by realize the purpose of this utility model：The upper end cover structure includes preceding upper end cover with after
Upper end cover, two end cap respectively by bolt on electric machine stand forebay and afer bay be fastenedly connected, wherein preceding upper end cover is
It is made of first member plate and right end plate two parts, is bolted connection between left and right end plate, rear upper end cover and preceding upper end cover are mutual
For the mirror-image structure of motor shaft vertical plane.
The first member plate is by upper left plate, left front panel, left plate, left blind cover, the connection of left engine base
Board group is at being welded connections between each plate.
The right end plate includes upper right plate, right front board, right plate, right blind cover, the connection of right engine base
Board group at, wherein be integrally formed with stretching on the left of right engine base connecting plate and win in succession, be to be welded to connect between each plate
Part.
The left front panel and right front board are bending and forming structure, from intermediate horizontal line by upper end bending, after bending under
End inclination angle is β=145 ° ~ 175 °.
It is reasonable in design according to box type electrical machine tilting upper end cover structure made of said program, pass through upper end cover
Be obliquely installed, the wind path area of box type electrical machine can be effectively increased, the result of ventilating heat dissipation of motor, Er Qieke can not only be improved
The length for reducing engine base and rotor, thus reduces design and cost of manufacture, while the rigidity of rotor also can be improved and reduce quiet
Amount of deflection reduces vibration when motor operation, extends the service life of motor, good practical effect.

Specific implementation mode
Referring to Fig. 1, Fig. 2, the box type electrical machine tilting upper end cover structure of the utility model, including preceding upper end cover 1 and it is rear on
End cap 4, two end cap respectively by bolt on electric machine stand forebay 2 and afer bay 3 be fastenedly connected, wherein preceding upper end cover 1
It is made of first member plate 1-1 and right end plate 1-2 two parts, is fastenedly connected by bolt 1-3 between left and right end plate, rear upper end cover 4
With the mirror-image structure of the motor shaft vertical plane each other of preceding upper end cover 1.
In conjunction with Fig. 2, referring to Fig. 3, Fig. 4, the first member plate 1-1 be by upper left plate 1-1-1,
Left front panel 1-1-2, left plate 1-1-3, left engine base connecting plate 1-1-4 and left blind cover 1-1-5 are formed, between each plate
For welded connections, left front panel 1-1-2 therein is bending and forming structure, from intermediate horizontal line by upper end bending, after bending with
Lower end inclination angle is β=145 ° ~ 175 °.
In conjunction with Fig. 2, referring to Fig. 5, Fig. 6, the right end plate 1-2 include upper right plate 1-2-1,
Right front board 1-2-2, right plate 1-2-3, right engine base connecting plate 1-2-4 and right blind cover 1-2-5, composition, wherein on the right side
It is integrally formed on the left of engine base connecting plate 1-2-4 and wins in succession 1-2-6 for connecting the stretching of first member plate 1-1, be weldering between each plate
Connecting connector, right front board 1-2-2 therein is bending and forming structure, from intermediate horizontal line by upper end bending, after bending under
End inclination angle is β=145 ° ~ 175 °.The utility model is tilted by the way that the upper end cover of box type electrical machine is arranged to tilted structure
Sponson can increase effectively motor ventilation area, improve the result of ventilating heat dissipation of motor, and can shorten engine base and rotor
Size improves the rigidity of engine base and rotor, reduces the vibration risk of motor in operation, extends the service life of motor.
