Description

Technical Field

[0001] The present application relates to the technical field of motors, and in particular to an anti-electro-corrosion motor. Background Art

[0002] Electric machinery (commonly known as "motor") refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. During the operation of the motor, high-frequency current and winding imbalance cause the shaft voltage to be too high. The current flows through the bearings, causing high-frequency electrical corrosion between the bearings, thus producing an anti-electrocorrosion motor. The casing of the anti-electrocorrosion motor in the prior art is generally manufactured as a whole, or connected with screws. When the motor needs to be repaired, professional tools are required to disassemble and repair the motor as a whole, which results in inconvenient disassembly and assembly and low maintenance efficiency. Utility Model Content

[0003] The present application provides an anti-electro-corrosion motor, which solves the problems of inconvenient assembly and disassembly and low efficiency of motors in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An anti-corrosion motor, comprising

[0006] The outer shell protects the internal components;

[0007] A stator, the stator being arranged in the housing;

[0008] Rotor;

[0009] The invention is characterized in that the shell comprises a first shell and a second shell, the first shell is provided with a positioning portion, the second shell is provided with a matching portion, the positioning portion and the matching portion cooperate to realize the disassembly and assembly connection of the first shell and the second shell, which not only makes the assembly and disassembly of the motor more convenient, but also improves the maintainability of the motor. When a component inside the motor fails, the shell can be easily removed for replacement or repair without disassembling the entire motor, thereby greatly improving work efficiency.

[0010] Furthermore, the positioning portion includes an L-shaped positioning groove, and the mating portion is clamped in the positioning groove, and the mating portion moves along the positioning groove. The characteristic of the L-shaped groove is that its bottom and side walls can provide support and positioning functions at the same time, thereby ensuring that the mating portion is not easy to loosen or shift after clamping.

[0011] Furthermore, a fixing hole is provided on the mating part, and a positioning hole communicating with the positioning groove is penetrated through the surface of the first shell, and the pin shaft passes through the positioning hole and cooperates with the fixing hole. The design of the fixing hole enables the mating part to be further fixed by the pin shaft after being snapped into the positioning groove. This fixing method is simple and effective, and can prevent the mating part from loosening or shifting during the operation of the motor, thereby ensuring a stable connection between the first shell and the second shell.

[0012] Furthermore, a first limiting surface is provided in the first shell. When the first shell is matched with the second shell, the end surface of the second shell abuts against the first limiting surface, which has a positioning effect, so that during the assembly process, the second shell can be accurately placed in the predetermined position, which greatly reduces assembly errors and improves assembly efficiency. At the same time, when the first shell and the second shell abut against each other, the contact area between the two is increased, thereby improving the tightness and stability of the connection, which helps to prevent the shell from loosening or shifting due to vibration or impact during the operation of the motor.

[0013] Furthermore, a second limiting surface is provided in the first housing, the stator includes a bracket, a clamping portion is provided on the bracket, a clamping groove is provided on the second limiting surface, the clamping portion is clamped in the clamping groove, and the clamping portion and the clamping groove cooperate with each other in a simple, fast and reliable manner. Compared with the traditional bolt connection or welding method, the clamping design greatly simplifies the assembly process and improves the assembly efficiency. At the same time, due to the close cooperation between the clamping portion and the clamping groove, the connection stability and reliability between the stator and the housing are also ensured.

[0014] Furthermore, a mounting portion is provided in a ring shape on the side surface of the bracket, the first limiting surface and the second limiting surface are connected by a connecting section, a mounting groove is provided on the connecting section, and the mounting portion cooperates with the mounting groove. The mounting portion provided in a ring shape on the side surface of the bracket provides additional support and fixing points for the stator. This design not only increases the contact area between the stator and the housing and improves the stability of the connection, but also helps to disperse the stress and vibration generated during the operation of the motor, and further protects the stability and reliability of the stator. The cooperation between the mounting groove provided on the connecting section and the mounting portion makes the assembly process of the stator simpler and more efficient.

[0015] Furthermore, the height of the mounting portion is smaller than the depth of the mounting groove. When the mounting portion cooperates with the mounting groove, the mounting portion is snapped into the mounting groove as a whole. Since the height of the mounting portion is smaller than the depth of the mounting groove, the mounting portion can penetrate deeper into the mounting groove during the snapping process to achieve a tighter fit. This design reduces the assembly gap and prevents loosening or displacement caused by vibration or impact. At the same time, the close connection between the outer shells also reduces the heat transfer resistance, allowing the motor to better dissipate heat and reduce the operating temperature.

[0016] Furthermore, the rotor includes a rotor core, which is provided with an accommodation groove for placing magnetic tiles. Limiting parts are provided on both sides of the accommodation groove. The limiting parts are used to limit the magnetic tiles. The accommodation groove not only improves the positioning accuracy of the magnetic tiles, but also helps to reduce the vibration and noise of the magnetic tiles during high-speed rotation. The design of the limiting parts can effectively limit the movement of the magnetic tiles in the accommodation groove, preventing the magnetic tiles from falling off or shifting due to vibration or centrifugal force during the operation of the motor. This design not only ensures the stability and reliability of the magnetic tiles, but also extends the service life of the motor.

[0017] Furthermore, the rotor also includes a plastic seal, which is sleeved outside the rotor core, and a positioning strip is provided on the plastic seal, a positioning cavity is formed between the two positioning strips, and a matching strip is provided on the rotor core, the matching strip matches the positioning cavity, and the positioning cavity formed between the two positioning strips provides a precise matching space for the matching strip on the rotor core. This matching structure enables the rotor core to maintain a fixed position inside the plastic seal, and is not prone to displacement or loosening. At the same time, the close matching of the positioning strip and the matching strip also enhances the overall stability of the rotor and reduces the performance degradation caused by vibration or impact.

[0018] Furthermore, a guiding surface is obliquely provided on the positioning bar, and a mating surface corresponding to the guiding surface is provided on the mating bar. The guiding surface cooperates with the mating surface. When the rotor approaches the positioning bar, the guiding surface guides the mating bar to slide smoothly into the positioning cavity, thereby reducing resistance and friction during assembly. This not only improves assembly efficiency, but also reduces the risk of damage caused by improper assembly, reduces position offset or instability problems caused by assembly errors, and improves the working performance of the rotor.

[0019] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0020] The utility model discloses an anti-electric corrosion motor, wherein the shell comprises a first shell and a second shell, the first shell is provided with a positioning portion, the second shell is provided with a matching portion, the positioning portion and the matching portion cooperate to realize the disassembly and assembly connection of the first shell and the second shell, which not only makes the assembly and disassembly of the motor more convenient, but also improves the maintainability of the motor. When a component inside the motor fails, the shell can be conveniently disassembled for replacement or repair without disassembling the entire motor, thereby greatly improving work efficiency.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0036] like Figures 1 to 9 As shown, this is an anti-electro-corrosion motor of the utility model, the main function of which is that a positioning portion 18 is provided on the first shell 10, and a matching portion 17 is provided on the second shell 11. The positioning portion 18 and the matching portion 17 cooperate with each other to realize the disassembly and assembly connection of the first shell 10 and the second shell 11, making the assembly and disassembly of the motor more convenient, while also improving the maintainability of the motor and greatly improving the work efficiency.

[0037] The utility model discloses an anti-electric corrosion motor, comprising a shell, a stator 14 arranged in the shell, a rotor 15 and a PCB board 16 (printed circuit board, which is a basic component for supporting and connecting electronic components) which are positioned and matched, the shell comprising a first shell 10 and a second shell 11 which are detachably connected, a rotating shaft 12 is connected in the rotor 15, bearings 13 are installed at both ends of the rotating shaft 12 and are connected to the shell, the stator 14 is connected to the shell, and the rotor 15 is located in the middle of the stator 14 and can rotate.

[0038] The rotor 15 includes a rotor core 30 and a plastic sealing member 21 sleeved on the rotor core 30. The rotor core 30 is provided with a placement groove 27 for placing magnetic tiles. The placement groove 27 is arranged along the central circumference of the rotor core 30. Limiting parts are provided on both sides of the placement groove 27 close to the edge of the rotor core 30. Two adjacent limiting parts 28 are used to limit the magnetic tiles. The placement groove 27 not only improves the positioning accuracy of the magnetic tiles, but also helps to reduce the vibration and noise of the magnetic tiles when rotating at high speed. The design of the limiting part 28 can effectively limit the movement of the magnetic tiles in the placement groove 27 to prevent the magnetic tiles from falling off or shifting due to vibration or centrifugal force during the operation of the motor. The plastic sealing member 21 is provided with a placement block 22 corresponding to the placement groove 27, and the placement block 22 is provided with a support part 26. A through groove 29 communicating with the placement groove 27 is formed between the two adjacent limiting parts 28, and the support part 26 extends It extends into the through groove 29 and abuts against the magnetic tile. A positioning strip 23 is circumferentially arranged in the middle position of the plastic sealing member 21, and a positioning cavity 25 is formed between the two positioning strips 23. A matching strip is arranged on the rotor core 30, and the matching strip is arranged in the placement groove 27 and directly opposite to the magnetic tile. The positioning strip 23 is trapezoidal, and a guide surface 24 is obliquely arranged on the positioning strip 23. A matching surface corresponding to the guide surface 24 is arranged on the matching strip. When the plastic sealing member 21 is matched with the rotor core 30, the guide surface 24 will guide the matching strip to slide smoothly into the positioning cavity 25 until the matching strip is matched with the positioning cavity 25, and the guide surface 24 is fitted with the matching surface, thereby reducing the resistance and friction during assembly. This not only improves the assembly efficiency, but also reduces the risk of damage caused by improper assembly, and also reduces the position offset or instability caused by assembly errors, thereby improving the working performance of the rotor 15.

[0039] A first limiting surface 36 and a second limiting surface 35 are provided in the first shell 10, and the first limiting surface 36 and the second limiting surface 35 are connected by a connecting section 34. The first limiting surface 36 and the second limiting surface 35 are arranged in a circular ring shape. The stator 14 includes a bracket 33, and a clamping portion 31 is provided on the bracket 33. The clamping portions 31 are evenly distributed along the central circumference of the stator 14, and the specific number is set according to actual conditions. The clamping portion 31 is located at one end that cooperates with the bracket 33 and the first shell 10, and a clamping groove 20 is provided on the second limiting surface 35. When the stator 14 cooperates with the first shell 10, the clamping portion 31 is clamped in the clamping groove 20. The cooperation between the clamping portion 31 and the clamping groove 20 is simple, fast and reliable. Compared with the traditional bolt connection or welding method, the clamping design greatly simplifies the assembly process and improves the assembly efficiency. At the same time, due to the close cooperation between the clamping portion 31 and the clamping groove 20, the connection stability and reliability between the stator 14 and the shell are also ensured.

[0040] The side of the bracket 33 is provided with a mounting portion 32 in an annular shape, and a mounting groove 19 corresponding to the mounting portion 32 is opened on the connecting section 34. The height of the mounting portion 32 is less than the depth of the mounting groove 19. When the stator 14 is matched with the first shell 10, the mounting portion 32 moves along the mounting groove 19 until the stator 14 and the first shell 10 are matched. The mounting portion 32 is integrally engaged in the mounting groove 19, which reduces the assembly gap and prevents loosening or displacement caused by vibration or impact. At the same time, the close connection between the shells also reduces the heat transfer resistance, so that the motor can better dissipate heat and reduce the operating temperature. The mounting portion 32 arranged in an annular shape on the side of the bracket 33 provides additional support and fixing points for the stator 14, which not only increases the contact area between the stator 14 and the shell, improves the stability of the connection, but also helps to disperse the stress and vibration generated during the operation of the motor, and at the same time plays a guiding role, which facilitates the connection between the stator 14 and the first shell 10, making the assembly process of the stator 14 simpler and more efficient.

[0041] The first housing 10 is provided with a ring-shaped positioning portion 18, and the positioning portion 18 is an L-shaped positioning groove. The second housing 11 is provided with a matching portion 17 corresponding to the positioning portion 18. The positioning portion 18 and the matching portion 17 cooperate to realize the disassembly connection between the first housing 10 and the second housing 11, which not only makes the assembly and disassembly of the motor more convenient, but also improves the maintainability of the motor. When a component inside the motor fails, the housing can be easily removed for replacement or repair without disassembling the entire motor, which greatly improves the work efficiency. Each matching portion 17 is provided with a fixing hole 38, and a positioning hole 39 communicating with the positioning groove is penetrated on the surface of the first housing 10. When the first housing 10 and the second housing 11 are connected, the first housing 10 and the second housing 11 are connected. When the second shell 11 is mated, the positioning hole 39 is coaxial with the fixing hole 38. When installing the first shell 10 and the second shell 11, first move the mating portion 17 axially along the positioning portion 18 until the mating portion 17 reaches the axial end face, rotate the second shell 11, and the mating portion 17 continues to move until it abuts against the end face. The pin 37 passes through the positioning hole 39 and is snapped into the fixing hole 38. The design of the fixing hole 38 allows the mating portion 17 to be further fixed by the pin 37 after being snapped into the positioning groove. This fixing method is simple and effective, and can prevent the mating portion 17 from loosening or shifting during the operation of the motor, thereby ensuring a stable connection between the first shell 10 and the second shell 11.
