Technical Field
[0001] This utility model relates to the field of shaded-pole motor technology, and in particular to an energy-saving and heat-dissipating shaded-pole motor. Background Technology
[0002] A shaded-pole motor is a type of induction motor, mainly composed of a stator and a rotor. Its rotor structure uses short-circuited annular conductors (such as aluminum or copper bars) to form a "shaded-pole" shape. This design allows the motor to have high torque during startup and operate over a wide load range.
[0003] In existing shaded-pole motors, the heat generated inside during operation and transferred to the stator can be quickly and instantly transferred to the first and second heat sinks and dissipated into the air, effectively preventing the motor coil windings from burning out due to overheating. However, when maintenance is required, it is inconvenient to perform the maintenance, which increases the difficulty and time for maintenance personnel. Therefore, an energy-saving and heat-dissipating shaded-pole motor is proposed to solve the above problems. Summary of the Invention
[0004] To overcome the above shortcomings, this utility model provides an energy-saving and heat-dissipating shaded-pole motor, aiming to improve the problem in the prior art that it is inconvenient to repair when maintenance is required, which increases the difficulty and time for maintenance personnel.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving and heat-dissipating shaded-pole motor, comprising a body, a rotating shaft fixedly connected to the output end of the body, a housing 1 and a housing 2 installed on the left and right sides of the body, a connector fixedly connected to each of the four right corners of the housing 1, a rotating block fitted to the right side of the connector, a semi-threaded rod fixedly connected to the left side of the rotating block, a nut threadedly connected to the left external side of the semi-threaded rod, threaded grooves opened at each of the four internal corners of the housing 2, the semi-threaded rod threadedly connected to the inside of the threaded grooves, and rotating components fixedly connected to the front and rear of the inner wall of the connector, the rotating components being used to expand the fixing area of the housing 1 and housing 2.

A sealing ring is engaged with the inner side of the threaded ring. The right side of the sealing ring is attached to the right side of the first sealing body. A retaining ring is engaged with the inner left side of the bearing.
[0008] As a further description of the above technical solution:
[0009] The rotating assembly includes a rotating seat, which is fixedly connected to the inner wall of the connector at the front and back. Rotating clamps are rotatably connected inside the rotating seat.
[0010] As a further description of the above technical solution:
[0011] Four inserts are fixedly connected to the left side of the threaded ring, and four insertion holes are opened inside the second sealing body. The inserts are engaged and connected inside the insertion holes.
[0012] As a further description of the above technical solution:
[0013] A protective cover is fixedly connected to the left side of the second housing, a cooling fan is fixedly connected inside the protective cover, and a protective frame is fixedly connected to the left side inside the protective cover.
[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by rotating the nut to separate it from the semi-threaded insert, and rotating the rotating block to rotate the semi-threaded insert out of the interior of housing two and housing one, so that it no longer squeezes the rotating clamp, the housing can be quickly and conveniently disassembled and replaced, so as to facilitate maintenance personnel to perform maintenance and reduce the difficulty and time of maintenance personnel.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 3 , Figure 4The present invention provides an embodiment of an energy-saving and heat-dissipating shaded-pole motor, comprising a body 1, a rotating shaft 2 fixedly connected to the output end of the body 1, a housing 3 and a housing 4 installed on the left and right sides of the body 1 to protect the shaded-pole motor, a connector 9 fixedly connected to the four right corners of the housing 3, a rotating block 10 attached to the right side of the connector 9, a semi-threaded rod 11 fixedly connected to the left side of the rotating block 10, a nut 14 threadedly connected to the left external side of the semi-threaded rod 11, threaded grooves 15 opened at the four internal corners of the housing 4, the semi-threaded rod 11 threadedly connected to the inside of the threaded grooves 15 to enable quick installation and disassembly of the housing, and rotating components fixedly connected to the front and rear of the inner wall of the connector 9 to expand the fixing area of the housing 3 and the housing 4.
[0032] The rotating assembly includes a rotating seat 12, which is fixedly connected to the inner wall of the connector 9 at the front and rear. Rotating clamps 13 are rotatably connected inside the rotating seat 12. A semi-threaded insert 11 is rotatably connected inside the connector 9 and is rotatably connected between the rotating clamps 13.
[0033] By rotating the nut 14 to separate it from the semi-threaded insert 11, the semi-threaded insert 11 can be rotated via the rotating block 10. By rotating the rotating block 10, the semi-threaded insert 11 rotates inside the threaded groove 15 and is screwed out of the interior of housing 2 4 and housing 1 3, separating from them and no longer pressing on the rotating clamp 13. This allows for quick and convenient disassembly and replacement of the housing, facilitating maintenance personnel and reducing the difficulty and time required for maintenance.
[0034] Reference Figure 1 , Figure 5 A bearing 16 is fixedly connected to the outer left side of the rotating shaft 2. A first sealing body 18 is engaged with the inner right side of the bearing 16. A threaded ring 19 is threadedly connected to the inner side of the first sealing body 18. A second sealing body 21 is attached to the left side of the threaded ring 19. A sealing ring 17 is engaged with the inner side of the threaded ring 19. The right side of the sealing ring 17 is attached to the right side of the first sealing body 18 to ensure the sealing between the bearing 16 and the rotating shaft 2. A retaining ring 23 is engaged with the inner left side of the bearing 16 to install and fix the sealing body and prevent it from falling out of the bearing 16. Four inserts 20 are fixedly connected around the left side of the threaded ring 19. Four insertion holes 22 are opened around the inner side of the second sealing body 21, and the inserts 20 are engaged with the inside of the insertion holes 22.
[0035] The first seal 18 and the second seal 21 installed inside the bearing 16 ensure a tight seal between the bearing 16 and the shaft 2, preventing lubricating oil from leaking out between the shaft 2 and the bearing 16. The first seal 18 is engaged inside the bearing 16 and can be disassembled and replaced as a whole. Alternatively, the second seal 21 can be rotated to separate the threaded ring 19 from the first seal 18, allowing for individual disassembly and replacement of the second seal 21. When the second seal 21 or the threaded ring 19 needs to be replaced, if the other does not need to be replaced, the threaded ring 19 can be separated from the first seal 18 and pulled to move its insert 20 out of the insertion hole 22, allowing for replacement of either the second seal 21 or the threaded ring 19. This ensures a tight seal between the bearing 16 and the shaft 2, preventing lubricating oil leakage and allowing for quick disassembly and replacement of the seals, preventing aging or failure after prolonged use.
[0036] Reference Figure 1 , Figure 2 , Figure 3 A protective cover 6 is fixedly connected to the left side of the second housing 4. A cooling fan 8 is fixedly connected inside the protective cover 6. A protective frame 7 is fixedly connected to the left side of the inside of the protective cover 6, so as to effectively dissipate heat from the body 1 and provide good protection for the cooling fan 8. The interior of the first housing 3 and the second housing 4 are provided with evenly distributed heat dissipation holes 5. The exterior of the first housing 3 and the second housing 4 are fixedly connected with evenly distributed heat dissipation fins 24 to expand the heat dissipation area and efficiency.
[0037] Heat is dissipated through the heat dissipation holes 5 inside the housing 1 3 and housing 2 4. The heat dissipation fins 24 further amplify the heat dissipation inside the housing 1 3 and housing 2 4 to accelerate the heat dissipation speed. The heat dissipation fan 8 further dissipates the heat, preventing the body 1 from being burned out due to heat not being dissipated in time during long-term operation.
[0038] Working principle: The heat dissipation holes 5 inside the housing 1 (3) and housing 2 (4) and the externally fixed heat sink 24 allow for ventilation and heat dissipation of the machine body 1. The cooling fan 8 further dissipates heat, preventing the machine body 1 from burning out due to insufficient heat dissipation during prolonged operation. When maintenance or disassembly is required, rotating the nut 14 separates it from the semi-threaded insert 11, and rotating the rotating block 10 causes the semi-threaded insert 11 to rotate and unscrew out of the housing 2 (4) and housing 1 (3), thus relieving pressure on the rotating clamp 13. This allows for quick and convenient disassembly and replacement of the housing. This design facilitates maintenance and reduces the difficulty and time required for repairs. The first seal 18 and the second seal 21 installed inside the bearing 16 ensure a tight seal between the bearing and the shaft 2. The first seal 18 is engaged inside the bearing 16 and can be disassembled and replaced as a whole. Alternatively, the second seal 21 can be rotated to separate the threaded ring 19 from the first seal 18, allowing for individual disassembly and replacement. This design ensures a tight seal between the bearing 16 and the shaft 2, preventing lubricant leakage and allowing for quick disassembly and replacement of the seals, thus preventing aging or failure after prolonged use.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
