Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, specifically a noise-reducing motor. Background Technology
[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses a current-carrying coil to generate a rotating magnetic field, which acts on the rotor to form a magnetoelectric torque. Electric motors are classified into DC motors and AC motors according to the power source they use. Most motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field is related to the direction of the current and the direction of the magnetic field lines.
[0003] Motors generate significant noise during operation, which can have a substantial impact on the working environment. Existing noise-reducing motors rely on protective covers for sound insulation, but these covers are inconvenient to install and remove. Furthermore, motors vibrate during high-speed operation, generating noise, which further reduces the effectiveness of the protective covers in sound insulation and hinders the normal operation of the motor. Utility Model Content
[0004] The purpose of this invention is to provide a noise-reducing motor to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The protective box has a top plate on top and a protective box at the bottom of the top plate. Both the inner walls of the protective box and the inner walls of the soundproof box are lined with sound-insulating material. The bottom of the protective box has a positioning post. The soundproof box has multiple positioning holes that cooperate with the positioning post. Both the outer walls of the protective box and the outer walls of the soundproof box have a locking plate. A locking plate is provided between two of the locking plates.

The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.
[0022] In one embodiment, such as Figure 1-3 As shown, a noise-reducing motor includes a motor body 1 and a base plate 3, and also includes:
[0023] The soundproof box 5 has a mounting groove 301 on its base plate 3. Multiple fixing blocks 22 are fixedly installed inside the mounting groove 301. Support rods 24 are fixedly installed on the fixing blocks 22. Movable blocks 13 are slidably sleeved on the top of the support rods 24. The soundproof box 5 is horizontally arranged between the multiple movable blocks 13. The motor body 1 is placed inside the soundproof box 5. The soundproof box 5 has two symmetrical slide rails 17 inside. Each of the two slide rails 17 has a slider 19 inside. A clamping plate 16 is arranged between the two sliders 19. The clamping plate 16 is an elastic plate that can fix motor bodies 1 of different sizes. The clamping plate 16 is located outside the motor body 1.
[0024] The protective box 4 and the soundproof box 5 are provided with a top plate 2 on top of the top plate 2 and a protective box 4 at the bottom. Both the protective box 4 and the soundproof box 5 are square boxes. The inner walls of the protective box 4 and the soundproof box 5 are provided with sound insulation material, which can absorb the noise generated by the motor 1 during use. The bottom of the protective box 4 is provided with a positioning post 14. The soundproof box 5 is provided with a plurality of positioning holes 15 that cooperate with the positioning post 14. The positioning post 14 passes through the positioning holes 15, so that the protective box 4 and the soundproof box 5 fit together. The outer walls of the protective box 4 and the soundproof box 5 are provided with a retaining plate 20. A locking plate 21 is provided between two retaining plates 20. The locking plate 21 passes through two retaining plates 20 to fix the protective box 4 and the soundproof box 5 in place.
[0025] A buffer mechanism is installed between the bottom plate 3 and the top plate 2 to buffer and reduce the vibration of the protective box 4 and the soundproof box 5.
[0026] The noise-reducing motor consists of a motor body 1, a soundproof box 5, and a protective box 4. The motor body 1 is installed inside the soundproof box 5. The protective box 4 is lowered and connected to the soundproof box 5, forming a protective cover over the motor body 1. This cover can absorb the noise emitted by the motor body 1. When the motor body 1 runs at high speed, it will cause the protective cover to vibrate up and down. The buffer mechanism buffers and dampens the vibration of the protective box 4 and the soundproof box 5, further reducing the noise generated by the motor body 1. As an example, the left, right, up, and down positions of the various components shown in the attached drawings are only one arrangement. The specific positions are set according to specific needs.
[0027] In one embodiment, such as Figure 1-3 As shown, the buffer mechanism includes a support rod 8, a buffer block 7, and a buffer spring 25. A fixed plate 6 is provided on the base plate 3, and a sliding groove 601 is provided on the fixed plate 6. The buffer block 7 is slidably arranged inside the sliding groove 601, and the support rod 8 is rotatably arranged on the buffer block 7. A connecting block 9 is provided at the bottom of the top plate 2, and the connecting block 9 is rotatably connected to the support rod 8. The buffer spring 25 is provided inside the sliding groove 601, and one end of the buffer spring 25 is connected to the buffer block 7. The protective box 4 is fixedly connected to the soundproof box 5. When the motor vibrates up and down, the protective box 4 drives the top plate 2 to move up and down. The top plate 2 drives the buffer block 7 to slide along the sliding groove 601 through the support rod 8. The return spring 25 pulls the support block 7 to buffer the external force on the support block 7 and reduce the vibration amplitude of the top plate 2 and the protective box 4.
[0028] In one embodiment, such as Figure 1-2 As shown, the protective box 4 is provided with a mounting plate 10 on the top. The top of the mounting plate 10 passes through the top plate 2 and is provided with a horizontal plate 11. Multiple locking bolts 12 are provided on the horizontal plate 11. The bottom end of the locking bolts 12 is connected to the top plate 2. The horizontal plate 11 can be pulled out from the mounting plate 10, so that the protective box 4 can be removed from the top plate 2.
[0029] In one embodiment, such as Figure 1-2 As shown, both ends of the clamping plate 16 are provided with fixing bolts 18, and the clamping plate 16 is installed inside the soundproof box 5 by fixing bolts 18.
[0030] In one embodiment, such as Figure 1-2 As shown, a support spring 23 is provided between the fixed block 22 and the movable block 13, and the support spring 23 is sleeved on the outside of the support rod 24.
[0031] The present invention provides a noise-reducing motor in the above embodiments. The motor body 1 is placed inside the soundproof box 5 and fixed by the clamping plate 16. The protective box 4 is pressed down so that the protective box 4 comes into contact with the soundproof box 5. The locking plate 21 is inserted for fixation. The protective box 4 and the soundproof box 5 form a protective cover covering the outside of the motor body 1, which can absorb the noise emitted by the motor body 1. When the motor body 1 vibrates up and down, the protective box 4 drives the top plate 2 to move up and down. The top plate 2 drives the buffer block 7 to slide along the sliding groove 601 through the support rod 8. The reset spring 25 pulls the support block 7 to buffer the external force on the support block 7, reduce the vibration amplitude of the top plate 2 and the protective box 4, and further reduce the noise generated by the motor body 1.
[0032] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
