Description

Technical Field

[0001] This utility model relates to the field of electric motor technology, and in particular to a permanent magnet waterproof electric motor. Background Technology

[0002] Electric motors convert electrical energy into mechanical energy and are widely used in industry, commerce, and homes to drive various electric equipment and mechanical devices. They can be used to provide rotary or linear mechanical motion, thereby driving the operation of equipment such as fans, pumps, compressors, home appliances, machine tools, and electric vehicles. They are key components in modern machinery and automation equipment, promoting productivity and technological progress.

[0003] Over time, the screws securing the front and rear covers of existing electric motors may loosen due to vibration, resulting in a lack of waterproof sealing. First, the waterproof performance deteriorates, allowing external moisture or humidity to enter the motor, causing internal parts to become damp or rust, especially the windings and bearings, which are prone to corrosion damage. Second, water entering the motor may cause electrical short circuits, leading to motor malfunctions or performance degradation, and may even pose safety hazards. In addition, internal lubricating oil may leak out, increasing friction, shortening the motor's lifespan, and increasing maintenance and replacement costs.

[0004] To address the above issues, we have developed a permanent magnet waterproof motor. Utility Model Content

[0005] This utility model discloses a permanent magnet waterproof motor, which aims to solve the technical problem of non-sealing and waterproofing.

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

[0007] A permanent magnet waterproof motor includes a housing. U-shaped plates are fixedly connected to both sides of the housing. Threaded rods are rotatably connected to both sides of the U-shaped plates. The adjacent ends of two corresponding threaded rods extend into the interior of the U-shaped plates and are fixedly connected to a first bevel gear. Adjusting rods are rotatably connected to one side of the U-shaped plates. The adjacent ends of two adjusting rods extend into the interior of the corresponding U-shaped plates and are fixedly connected to a second bevel gear. The second bevel gears mesh with the corresponding first bevel gears. Ratchets are fixedly connected to the exterior of each adjusting rod. Fixing blocks are fixedly connected to the exterior of each U-shaped plate. Limiting pins are rotatably connected to the exterior of each U-shaped plate, and each limiting pin engages with a corresponding ratchet. A spring is fixedly connected between the top of the fixing block and the bottom of the limiting pin.

[0008] The design incorporates a U-shaped plate and threaded rod for adjusting and securing various parts of the motor. The bevel gear engagement mechanism allows the adjusting rod to rotate the threaded rod for precise adjustment. A ratchet and limit pin combined with a spring provide a simple yet effective locking mechanism to prevent the adjusting rod from rotating back, ensuring safety and operational stability. This simplifies installation and adjustment and prevents unnecessary loosening or displacement during use.

[0009] In a preferred embodiment, a front cover is provided on one side of the housing, and a rear cover is provided on the side of the housing away from the front cover. Fixing plates are fixedly connected to both sides of the front cover and the rear cover, and the threaded rods are threadedly connected to the corresponding fixing plates.

[0010] The front and rear covers are used to enclose the inside of the motor, providing physical protection. The connection between the fixing plate and the threaded rod makes the entire assembly more stable and less prone to falling off. At the same time, it facilitates quick assembly and disassembly, extends the service life of the motor, and improves the convenience of maintenance.

[0011] In a preferred embodiment, bearings are fixedly connected inside both the front cover and the rear cover, and a torsion shaft is fixedly connected between the two bearings, with one end of the torsion shaft penetrating through the front cover.

[0012] By setting bearings to support the rotation of the torque shaft, friction and energy loss are reduced, improving the efficiency and stability of the motor, which helps to transmit power and ensures stable power output and efficient operation of its internal components.

[0013] In a preferred embodiment, sealing rings are fixedly connected to both ends of the housing, and the front cover and the rear cover are used in conjunction with the sealing rings.

[0014] By incorporating a sealing ring to provide waterproofing, the internal components of the motor are protected from humid environments, preventing the ingress of water and dust, thus enhancing the protection level of the device and ensuring the safety and longevity of the motor.

[0015] In a preferred embodiment, a commutator is fixedly connected to the top of the housing, and a terminal block is fixedly connected to the input end of the commutator.

[0016] By setting a commutator to change the current direction, the rotation direction of the motor can be adjusted as needed. The terminal provides a stable electrical connection, which facilitates power supply and signal transmission, thereby improving the control flexibility and ease of use of the motor.

[0017] In a preferred embodiment, a winding is fixedly connected to the top of the housing and to one side of the commutator.

[0018] The winding is one of the core components of an electric motor, responsible for generating a magnetic field. Its design directly affects the motor's power and efficiency, enabling the motor to operate efficiently.

[0019] In a preferred embodiment, a mounting base is fixedly connected to the bottom of the housing, and the mounting base has four through slots symmetrically opened inside.

[0020] By providing a stable mounting base for the motor, the stability and safety of the equipment are ensured, thereby improving its reliability and service life during operation.

[0021] The permanent magnet waterproof motor provided by this utility model has the following advantages:

[0022] In this invention, when the aforementioned permanent magnet waterproof motor is in use, the rotation of the adjusting rod drives the second bevel gear to mesh with the first bevel gear at one end of the threaded rod to achieve threaded fastening. Simultaneously, the use of a limiting pin and ratchet ensures self-locking after fastening, preventing loosening even after shaking, thus achieving a waterproof seal. On one hand, a well-sealed motor ensures that internal lubricating oil or grease does not leak, maintaining lubrication of the rotor, bearings, and other components, reducing friction and wear, and ensuring stable operation of the motor over a long period. On the other hand, because external moisture cannot enter, the internal windings and other electrical components of the motor will not experience short circuits or leakage due to moisture, thereby reducing the risk of electrical failures and improving the safety and reliability of the motor. Compared with traditional devices, this significantly improves operational quality and efficiency. Attached Figure Description

[0035] In this embodiment, the front cover 11 and the rear cover 12 are used to enclose the inside of the motor and provide physical protection. The connection between the fixing plate 13 and the threaded rod 3 makes the entire assembly more stable and less prone to falling off. At the same time, it facilitates quick disassembly and assembly, extends the service life of the motor and improves the convenience of maintenance.

[0036] Reference Figure 1 and Figure 5 In a preferred embodiment, bearings 14 are fixedly connected inside both the front cover 11 and the rear cover 12, and a torsion shaft 15 is fixedly connected between the two bearings 14, with one end of the torsion shaft 15 penetrating through the front cover 11.

[0037] In this embodiment, the bearing 14 supports the rotation of the torque shaft 15, reduces friction and energy loss, improves the efficiency and stability of the motor, helps to transmit power, and ensures stable power output and efficient operation of its internal components.

[0045] In this embodiment, the mounting base 20 provides a stable installation for the motor, ensuring the stability and safety of the equipment and improving its reliability and service life during operation.

[0046] Working Principle: When the above-mentioned permanent magnet waterproof motor is in use, the housing 1 is the main external protective structure of the motor. A U-shaped plate 2 is fixedly connected to each side of the housing 1 to provide mechanical stability and support. The two ends of the housing 1 are equipped with sealing rings 16, which are used in conjunction with the front cover 11 and the rear cover 12 to ensure the waterproof performance of the motor. Each U-shaped plate 2 has a pair of threaded rods 3 and adjusting rods 5, which are connected by the meshing of the first bevel gear 4 and the second bevel gear 6. When the adjusting rod 5 is rotated, the threaded rods 3 can be adjusted accordingly to change their support and fixed positions. The adjusting rod 5 is externally fixedly connected to a ratchet 7, which, through the action of the limit pin 9 and the spring 10, provides a stable anti-adjustment force to prevent accidental loosening and allows locking or releasing when needed. Since external moisture cannot enter, the windings 19 and other electrical parts inside the motor will not short-circuit or leak due to moisture, thereby reducing the risk of electrical failure and improving the safety and reliability of the motor. Compared with traditional devices, this greatly improves the quality of operation and efficiency of use.
