Description

Technical Field

[0001] This utility model relates to the technical field of motor fan covers, and in particular to a structurally stable motor fan cover base. Background Technology

[0002] In industrial motor equipment, the fan cover is a key component used to fix the cooling fan blades. Its structural stability directly affects the service life of the main motor. Traditional fan covers usually use screws to connect directly from the bottom, which means that the screw nuts face the main motor. However, since the main motor generates a strong magnetic field, the screws are easily affected by the magnetic field force, causing them to loosen or even fall off. Loose screws may be attracted to the main motor, which not only affects the normal operation of the main motor, but may also cause short circuits in the main motor, spindle jamming, and other phenomena. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a structurally stable motor fan cover base, including an upper cover, a base, screws, a motor and fan blades. The upper cover is detachably connected to the base by screws, and the upper cover and the base are combined to form a mounting groove for mounting the motor. The output end of the motor passes through the upper cover and is connected to the fan blades. The base has a lower mounting part distributed in a circle. The lower mounting part has a side hole for connecting an external fan cover and a threaded hole for connecting screws. The upper cover has an upper mounting part corresponding to the lower mounting part. The screw passes through the upper mounting part and is threaded to the lower mounting part, with the screw head facing the direction of the fan blades.

[0004] By adopting the above technical solution, an upper mounting part and a lower mounting part are added to the structure of the upper cover and the base, thereby changing the installation direction of the screws. By optimizing the installation position of the screws, the problem of screw loosening caused by magnetic field force in traditional wind cover seats is effectively solved, ensuring reliable screw fastening, improving the stability of the wind cover seat structure, and having significant practical value.

[0005] The present invention is further configured such that the lower mounting part includes a rectangular part and a cylindrical part, the threaded hole and the side hole are respectively provided on the rectangular part and the cylindrical part, the outer contour of the upper mounting part is adapted to the rectangular part, and the upper mounting part is provided with a mounting hole corresponding to the threaded hole.

[0006] Furthermore, the opening of the top cover is provided with an inner stop, and the base is provided with an outer stop corresponding to the inner stop.

[0007] Using the above technical solution, the top cover and the base are both integral aluminum castings. The positioning of the inner and outer stops makes the top cover and the base coaxially connected. Since the outer contour of the upper mounting part is the same as the rectangular part of the lower mounting part, the assembled fan cover base is uniform and beautiful, meeting the requirements of lightweight design.

[0008] The present invention is further configured such that the upper cover and the base are respectively provided with corresponding upper ring portion and lower ring portion, and the upper ring portion and the lower ring portion are combined to form the mounting groove, and the upper and lower ends of the motor are respectively provided with positioning portions for engaging the upper ring portion and the lower ring portion.

[0009] Furthermore, the upper cover is provided with a through hole and an outer ring portion coaxially distributed with the upper ring portion. The outer ring portion is used to install bearings, and the output shaft of the motor passes through the through hole and is connected to the fan blades.

[0010] Furthermore, the upper and lower ring portions are fitted with sound-insulating pads for supporting the motor.

[0011] Furthermore, the base is provided with a wire hole for connecting an external power supply to the motor between the two sets of lower mounting parts.

[0012] By adopting the above technical solution, the upper and lower ring parts form a coaxial positioning structure, which ensures automatic centering of the motor during installation. The limiting of the upper and lower ring parts prevents the motor from moving radially during operation, and the limiting of the sound insulation pad prevents the motor from moving axially during operation, thereby achieving precise installation and stable operation of the motor.

[0013] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Attached Figure Description

[0021] like Figure 1 , 2 As shown, this embodiment provides a structurally stable motor fan cover holder, including an upper cover 1, a base 2, screws 3, a motor 4, and a fan blade 5. The upper cover 1 is detachably connected to the base 2 by the screws 3, and the upper cover 1 and the base 2 are combined to form a mounting groove 6 for mounting the motor 4. The output end of the motor 4 passes through the upper cover 1 and is connected to the fan blade 5. The base 2 is provided with a lower mounting part 7 distributed in a circular pattern. The lower mounting part 7 is provided with a side hole 8 for connecting an external fan cover and a threaded hole 9 for connecting the screws 3. The upper cover 1 is provided with an upper mounting part 10 corresponding to the lower mounting part 7. The screws 3 pass through the upper mounting part 10 and are threadedly connected to the lower mounting part 7, and the nuts of the screws 3 face the direction of the fan blade 5.

[0022] Combination Figure 3 , 4 As shown, in this embodiment, the lower mounting part 7 includes a rectangular part 11 and a cylindrical part 12. Threaded holes 9 and side holes 8 are respectively provided on the rectangular part 11 and the cylindrical part 12. The outer contour of the upper mounting part 10 is adapted to the rectangular part 11, and the upper mounting part 10 is provided with mounting holes 13 corresponding to the threaded holes 9. The opening of the upper cover 1 is provided with an inner stop 14, and the base 2 is provided with an outer stop 15 corresponding to the inner stop 14. The upper cover 1 and the base 2 are both integral aluminum castings 16. Through the positioning of the inner stop 14 and the outer stop 15, the upper cover 1 and the base 2 are coaxially connected. Since the outer contour of the upper mounting part 10 is the same as the structure of the rectangular part 11 of the lower mounting part 7, the assembled wind cover base is uniform and beautiful, meeting the requirements of lightweight design.

[0023] In this embodiment, the upper cover 1 and the base 2 are respectively provided with corresponding upper ring portion 17 and lower ring portion 18, and the upper ring portion 17 and lower ring portion 18 are combined to form a mounting groove 6. The upper and lower ends of the motor 4 are respectively provided with positioning portions 19 for engaging the upper ring portion 17 and the lower ring portion 18. The upper cover 1 is provided with a through hole 20 and an outer ring portion 21 coaxially distributed with the upper ring portion 17. The outer ring portion 21 is used to install bearings.

The ring portion 18 is fitted with a sound insulation pad 23 for supporting the motor 4. The base 2 is located between the two sets of lower mounting portions 7 and has a wire hole 24 for connecting the external power supply of the motor 4. The upper ring portion 17 and the lower ring portion 18 form a coaxial positioning structure to ensure that the motor 4 is automatically aligned during installation. The upper ring portion 17 and the lower ring portion 18 limit the motor 4 from radial movement during operation, and the sound insulation pad 23 limits the motor 4 from axial movement during operation, thereby achieving precise installation and stable operation of the motor 4.

[0024] Combination Figure 5 , 6As shown, the working principle of this utility model is as follows: The heat dissipation structure of this utility model is independent of the main motor 25. The base 2 is connected to the fan cover 26 through the side hole 8 and is installed at the tail of the main motor 25 through the fan cover 26. The motor 4 controls the fan to work, thereby playing a role in forced heat dissipation of the main motor 25. By changing the structure of the upper cover 1 and the base 2, that is, by providing an upper mounting part 10 and a lower mounting part 7 on the outer side of the upper cover 1 and the base 2 respectively, the direction of the screw 3 nut is changed from facing the main motor 25 to facing away from the main motor 25, which effectively prevents the screw 3 from loosening due to the magnetic field of the main motor 25 and maintains the stability of the structure.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
