Description

Technical Field

[0001] This utility model relates to the field of motor rotor sealing technology, and in particular to a moisture-proof and sealed motor rotor. Background Technology

[0002] A moisture-proof and sealed motor rotor is mainly used in industrial environments with high sealing requirements, such as food processing, textile printing and dyeing, and sewage treatment. The aim is to ensure stable operation of the motor rotor in complex environments by optimizing the sealing structure.

[0003] Motor rotors typically consist of a rotor body, a protective shell, and end covers. Installation often involves directly fixing the end covers to the protective shell using bolts. However, this connection method has significant drawbacks: firstly, bolted connections have low precision, easily leading to misalignment between the end covers and the protective shell, affecting the overall structural stability; secondly, relying solely on bolt tightening force for sealing has limited effectiveness. In humid environments, moisture can easily enter the protective shell through the connection gaps, affecting the normal operation of the motor rotor and reducing the equipment's lifespan.

[0004] Therefore, a moisture-proof and sealed motor rotor is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a moisture-proof and sealed motor rotor, which aims to improve the problem that some devices in the prior art rely solely on the tightening force of bolts to achieve sealing, resulting in limited sealing effect. In humid environments, moisture can easily enter the protective shell through the connection gaps, affecting the normal operation of the motor rotor and reducing the service life of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A moisture-proof and sealed motor rotor includes a protective shell, a transmission mechanism inside the protective shell, cover plates at both ends of the protective shell, a magnetic suction plate inside the protective shell, multiple arc-shaped threaded plates at the adjacent ends of the two cover plates, multiple limiting connecting blocks outside the cover plates, two limiting long plates fixedly connected to the outside of the limiting connecting blocks, a sealing mechanism at the distant ends of the multiple limiting connecting blocks, an inclined plate slidably connected inside the limiting connecting blocks, and a threaded rod threadedly connected inside the inclined plate.

[0008] As a further description of the above technical solution:

[0009] The sealing mechanism includes multiple sliding rods, the outside of which is slidably connected to the inside of the limiting connecting block, and a spring is sleeved on the outside of each sliding rod. A rubber block is fixedly connected to the outside of every two sliding rods.

[0010] As a further description of the above technical solution:

[0011] One end of the spring is fixedly connected to the outside of the limiting connecting block, and the other end of the spring is fixedly connected to the outside of the rubber block;

[0012] As a further description of the above technical solution:

[0013] The outer side of the limiting plate is slidably connected to the inner side of the arc-shaped threaded plate, and the outer side of the limiting connecting block is in contact with the outer side of the arc-shaped threaded plate.

[0014] As a further description of the above technical solution:

[0015] The threaded rod is externally rotatably connected to the inside of the cover plate, and the inclined plate is externally slidably connected to the inside of the cover plate;

[0016] As a further description of the above technical solution:

[0017] The rubber block is externally slidably connected to the inside of the arc-shaped threaded plate, and the rubber block is externally slidably connected to the outside of the cover plate.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, a threaded rod drives an inclined plate to push a limiting connecting block, allowing the limiting plate to slide within the arc-shaped threaded plate. This achieves precise alignment between the cover plate and the protective shell, ensuring installation stability. A spring outside the sliding rod pushes a rubber block, ensuring it tightly adheres to the arc-shaped threaded plate and the cover plate, achieving a good seal and effectively preventing moisture ingress. A magnetic plate enhances the connection stability between the cover plate and other components, further improving sealing performance. An internal transmission mechanism within the protective shell drives the entire system, enabling the motor rotor to operate continuously and stably in a moisture-proof and sealed environment, extending the equipment's service life.

[0026] 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.

[0027] Reference Figures 1 to 3 This utility model provides an embodiment of a moisture-proof and sealed motor rotor, including a protective shell 1, which serves as an external protective structure for the motor rotor, providing installation space and protection for the internal transmission mechanism 2, isolating the external environment from the direct influence of internal components, and maintaining a stable operating environment for the internal structure. The transmission mechanism 2 is housed inside the protective shell 1, and is the core component for power transmission and operation of the motor rotor. Through its own operation, it drives the entire motor rotor to work, ensuring that the motor rotor can output power. Sealing plates 4 are provided at both ends of the protective shell 1, serving to seal the protective shell 1 and prevent external moisture, dust, and other impurities from entering. Inside the protective shell 1, a mounting carrier is provided for components such as the magnetic suction plate 3 and the arc-shaped threaded plate 5. The outside of the rubber block 10 is slidably connected to the inside of the arc-shaped threaded plate 5. Utilizing the elasticity and sealing properties of the rubber material, the gaps between the components are filled, effectively preventing moisture from entering the interior of the protective shell 1. The outside of the rubber block 10 is slidably connected to the outside of the cover plate 4. The inside of the protective shell 1 is equipped with a magnetic suction plate 3, which can enhance the connection stability between the cover plate 4 and other related components during the operation of the motor rotor, reduce the relative displacement between components, and indirectly ensure the durability of the sealing performance. Multiple arc-shaped threaded plates 5 are provided at the adjacent ends of the two cover plates 4.

[0028] Reference Figures 2 to 4The limiting plate 7 provides a sliding track, which, in cooperation with the limiting plate 7, restricts the movement direction of the limiting connecting block 6, ensuring that the cover plate 4 can accurately dock with the protective shell 1 during installation. The cover plate 4 has multiple limiting connecting blocks 6 on its outside, which contact the arc-shaped threaded plate 5 on the outside and interact with the inclined plate 11 on the inside. Under the push of the inclined plate 11, they move, thereby driving the limiting plate 7 to move. It is the intermediate component connecting the inclined plate 11 and the limiting plate 7, and plays the role of transmitting force. Two limiting plates 7 are fixedly connected to the outside of the limiting connecting block 6. The outside of the limiting connecting block 6 slides inside the arc-shaped threaded plate 5. Through the sliding process, the cover plate 4 is guided to move closer to the protective shell 1, ensuring the accuracy of the position when the cover plate 4 docks with the protective shell 1 and improving the installation accuracy. The outside of the limiting plate 7 is slidably connected to the inside of the arc-shaped threaded plate 5, and the outside of the limiting connecting block 6 is in contact with the outside of the arc-shaped threaded plate 5. The far ends of the multiple limiting connecting blocks 6 are provided with sealing mechanisms.

[0029] The sealing mechanism includes multiple sliding rods 8, which slide inside the limiting connecting block 6 as part of the sealing mechanism. They provide guidance for the movement of the rubber block 10, ensuring that the rubber block 10 can move in a predetermined direction and guaranteeing the stability of the sealing action. The sliding rods 8 are externally slidably connected to the inside of the limiting connecting block 6. A spring 9 is sleeved on the outside of the sliding rods 8. One end of the spring 9 is connected to the limiting connecting block 6, and the other end is connected to the rubber block 10. When the cover plate 4 and the protective shell 1 are mated, the spring 9 pushes the rubber block 10 through its own elasticity, so that the rubber block 10 can fit tightly against the relevant components and enhance the sealing effect. One end of the spring 9 is fixedly connected to the outside of the limiting connecting block 6, and the other end of the spring 9 is fixedly connected to the outside of the rubber block 10.

[0030] Reference Figures 3 to 4 Each pair of sliding rods 8 is externally fixedly connected to a rubber block 10. An inclined plate 11 is slidably connected inside the limiting connecting block 6. It is located inside the limiting connecting block 6 and is threadedly connected to the threaded rod 12. Driven by the threaded rod 12, it slides inside the cover plate 4. Through sliding, it interacts with the limiting connecting block 6, providing driving force for the movement of the limiting connecting block 6. The inclined plate 11 is internally threadedly connected to the threaded rod 12 and is rotatably connected inside the cover plate 4. Through its own rotation, it drives the inclined plate 11 to slide inside the cover plate 4. It is the power input component in the entire installation process, controlling the movement state of the inclined plate 11, and thus regulating the docking process between the cover plate 4 and the protective shell 1. The threaded rod 12 is externally rotatably connected to the inside of the cover plate 4, and the inclined plate 11 is externally slidably connected to the inside of the cover plate 4.

[0031] Working principle: When operating this moisture-proof and sealed motor rotor, the cover plate 4 and the protective shell 1 must first be installed. At this time, the threaded rod 12 needs to be rotated. Since the external rotatable connection of the threaded rod 12 is to the inside of the cover plate 4, and it is threadedly connected to the inside of the inclined plate 11, while the external sliding connection of the inclined plate 11 is to the inside of the cover plate 4, the inclined plate 11 will slide inside the cover plate 4 as the threaded rod 12 rotates.

[0032] During the sliding process of the inclined plate 11, it interacts with the limiting connecting block 6. The limiting connecting block 6 has multiple limiting elongated plates 7 on its exterior, while the end of the cover plate 4 has multiple arc-shaped threaded plates 5 on its adjacent sides. The exterior of the limiting elongated plates 7 is slidably connected to the interior of the arc-shaped threaded plates 5, and the exterior of the limiting connecting block 6 contacts the exterior of the arc-shaped threaded plates 5. The sliding of the inclined plate 11 pushes the limiting connecting block 6 to move, which in turn causes the limiting elongated plates 7 to slide within the arc-shaped threaded plates 5, causing the cover plate 4 to gradually approach the protective shell 1 until the cover plate 4 and the protective shell 1 are initially aligned.

[0033] Next, the sealing mechanism begins to function. The sealing mechanism includes multiple sliding rods 8, the outer surfaces of which are slidably connected to the interior of the limiting connecting block 6. A spring 9 is fitted around the outer surface of each sliding rod 8. One end of the spring 9 is fixedly connected to the exterior of the limiting connecting block 6, and the other end is fixedly connected to the exterior of the rubber block 10. The exterior of the rubber block 10 is slidably connected to the interior of the arc-shaped threaded plate 5 and the exterior of the cover plate 4. When the cover plate 4 mates with the protective shell 1, the rubber block 10, under the elastic force of the spring 9, tightly adheres to the arc-shaped threaded plate 5 and the cover plate 4, thereby achieving a good sealing effect and preventing moisture from entering.

[0034] Afterwards, the transmission mechanism 2 inside the protective shell 1 begins to operate, driving the entire motor rotor. During operation, the magnetic plates 3 at both ends of the cover plate 4 also play a role, helping to enhance the connection stability between the cover plate 4 and other components, further ensuring sealing performance, and ensuring the motor rotor operates continuously and stably in a moisture-proof and sealed environment. From the installation of the cover plate 4 to the sealing of the sealing mechanism, and then to the operation of the transmission mechanism 2, all components cooperate with each other to achieve the normal operation of the moisture-proof and sealed motor rotor.

[0035] 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.
