Description

Technical Field

[0001] This utility model relates to the field of rotor core technology, and in particular to an easy-to-fix rotor core for generators. Background Technology

[0002] The rotor core refers to the core assembly of the generator's central device. It is one of the core parts of the generator rotor, making the generator rotor rotation more stable and having good magnetic permeability and anti-magnetic saturation performance. During generator operation, the current generates a strong magnetic field, which further generates a rotating magnetic field through the rotor core and rotor guide shaft, thereby driving the rotor to rotate.

[0003] Rotor cores are typically made of silicon steel sheets coated with oxide, which effectively reduces hysteresis and eddy current losses, improving generator efficiency and stability. High-performance silicon steel rotor cores offer significant advantages in enhancing motor efficiency and stability.

[0004] Existing generator rotor cores require specific bolts and fixing tools to install inside the generator, and multiple bolts need to be tightened for fixation. This installation method is not only labor-intensive but also inefficient. Therefore, this utility model provides an easy-to-fix rotor core for generators. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention provides an easily fixed rotor core for a generator. It has the following advantages:

[0018] 1. By rotating the bolt column, the bolt column moves towards the fixed block via the thread. The bolt column pushes the trapezoidal slider to move via the push rod. The trapezoidal slider pushes the fixed block upward via the inclined surface. When the fixed block moves upward and abuts against the inner wall of the fixed groove, the rotating shaft cylinder and the rotor lamination are fixed, so that the rotor lamination can be quickly installed and fixed on the rotating shaft cylinder.

[0019] 2. By rotating the bolt column in the opposite direction, the bolt column drives the push rod to move away from the fixed block, thereby releasing the compression on the return spring A and return spring B. The return spring A and return spring B restore the trapezoidal slider and the fixed block to their original positions through elastic deformation, thereby releasing the fixation of the rotor lamination and achieving the effect of quick disassembly.

Detailed Implementation

[0027] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: an easily fixed rotor core for a generator, including a rotor cylinder 1, a rotor lamination 6 provided on the inner wall of the rotor cylinder 1, and a rotor cover 2 fixedly connected to one side of the rotor cylinder 1 by bolts. A drive gear shaft 3 is rotatably connected to the surface of the rotor cover 2. A mounting plate A4 is fixedly connected to one side of the drive gear shaft 3. A mounting plate B5 is fixedly connected to one side of the mounting plate A4 by bolts. A rotating shaft cylinder 7 is fixedly connected to one side of the mounting plate B5. The surface of the rotating shaft cylinder 7 is slidably connected to the inner wall of the center of the rotor lamination 6.

[0028] Reference Figure 4 and Figure 5As shown in this embodiment: a sliding groove 8 is provided on the surface of the rotor cylinder, the sliding groove 8 is connected to the inner wall of the rotor cylinder 1, and a fixing block 9 is slidably connected to the surface of the sliding groove 8. A bolt post 10 is threadedly connected to the inner wall of the rotor cylinder 1. A push rod 11 is rotatably connected to one end of the bolt post 10, and a trapezoidal slider 12 is abutted at the other end of the push rod 11. An inclined surface is provided on the side of the fixing block 9 near the trapezoidal slider 12, and the inclined surface abuts against the surface of the trapezoidal slider 12. A fixing groove 16 is provided on the inner wall of the rotor lamination 6, and the size of the fixing groove 16 is adapted to the size of the fixing block 9.

[0029] Furthermore, by rotating the bolt post 10, the bolt post 10 moves towards the fixing block 9 via the thread. The bolt post 10 pushes the trapezoidal slider 12 to move via the push rod 11. The trapezoidal slider 12 pushes the fixing block 9 upward via the inclined surface. When the fixing block 9 moves upward and abuts against the inner wall of the fixing groove 16, the rotating shaft cylinder 7 and the rotor lamination 6 are fixed together, so that the rotor lamination 6 can be quickly installed and fixed on the rotating shaft cylinder 7.

[0030] Reference Figure 4 and Figure 5 As shown, specifically, a return spring A13 is fixedly connected to the side of the trapezoidal slider 12 away from the push rod 11. One end of the return spring A13 is fixedly connected to the inner wall of the rotating shaft cylinder 7. Both ends of the fixed block 9 are fixedly connected to a return plate 14. A return spring B15 is fixedly connected to the side of the return plate 14 away from the trapezoidal slider 12. One end of the return spring B15 is fixedly connected to the rotating shaft cylinder 7. A positioning groove 17 is opened on one side of the rotor lamination 6. A positioning ring 18 is slidably connected to the inner wall of the positioning groove 17. One side of the positioning ring 18 is fixedly connected to the surface of the mounting plate B5.

[0031] Furthermore, when the trapezoidal slider 12 moves, the side of the trapezoidal slider 12 away from the push rod 11 presses the return spring A13, causing the return spring A13 to undergo elastic deformation. At the same time, the return plates 14 on both sides of the fixing block 9 also press the return spring B15, causing the return spring B15 to undergo elastic deformation. When it is necessary to disassemble the rotor lamination 6, the bolt column 10 is rotated in the opposite direction, causing the bolt column 10 to drive the push rod 11 to move away from the fixing block 9. At the same time, the compression on the return springs A13 and B15 is released, allowing the return springs A13 and B15 to restore the trapezoidal slider 12 and the fixing block 9 to their original positions through the recovery of elastic deformation, thereby releasing the fixing of the rotor lamination 6 and achieving the effect of quick disassembly.

[0032] Working principle: In use, first, the rotor lamination 6 is placed into the rotor cylinder 1. Then, the rotating shaft cylinder 7 is inserted into the inner wall of the center of the rotor lamination 6. By rotating the bolt post 10, the bolt post 10 moves towards the fixing block 9 via the thread. The bolt post 10 pushes the trapezoidal slider 12 to move via the push rod 11. The trapezoidal slider 12 pushes the fixing block 9 upward with the help of the inclined surface. When the fixing block 9 moves upward and abuts against the inner wall of the fixing groove 16, the rotating shaft cylinder 7 and the rotor lamination 6 are fixed, thus allowing the rotor lamination 6 to be quickly installed and fixed on the rotating shaft cylinder 7. When the trapezoidal slider 12 moves, the side of the trapezoidal slider 12 away from the push rod 11 compresses the return spring A13, causing the return spring A13 to undergo elastic deformation. At the same time, the sides of the fixing block 9... The reset plate 14 also compresses the reset spring B15, causing the reset spring B15 to undergo elastic deformation. When it is necessary to disassemble the rotor lamination 6, the bolt column 10 is rotated in the opposite direction, causing the bolt column 10 to drive the push rod 11 to move away from the fixing block 9. At the same time, the compression on the reset spring A13 and the reset spring B15 is released, allowing the reset spring A13 and the reset spring B15 to restore the trapezoidal slider 12 and the fixing block 9 to their original positions through the recovery of elastic deformation, thereby releasing the fixation of the rotor lamination 6 and achieving the effect of quick disassembly. After the rotor lamination 6 is fixed, the fixing plate A and the fixing plate B can be connected by bolts. Then, the rotor cover 2 is inserted into the drive gear shaft 3, and the rotor cover 2 is fixedly connected to the rotor cylinder 1 by bolts, thereby completing the fixed installation of the generator.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
