Abstract
Description
Technical Field
[0001] This utility model relates to the field of torque motor technology, and in particular to a high-reliability, low-noise torque motor. Background Technology
[0002] A torque motor is a special type of motor, characterized by its ability to continue operating at low speeds or even when stalled without damage. In this operating mode, the motor can provide a stable torque to the load, hence the name torque motor. The shaft of a torque motor does not output power at a constant power output, but rather at a constant torque output.
[0003] Traditional torque motors generate significant noise during operation, which is typically mitigated by soundproof enclosures. However, the soundproofing effect is often poor, allowing the noise to still affect the working environment. Therefore, we propose a highly reliable, low-noise torque motor. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a high-reliability, low-noise torque motor.
[0005] This utility model is achieved using the following technical solution: a high-reliability, low-noise torque motor, including a fixed base plate, a torque motor body fixedly connected to the top of the fixed base plate, a through groove opened at the bottom of the fixed base plate, a soundproof cover provided at the upper end of the fixed base plate, an extension plate fixedly connected to the surface of the soundproof cover, a threaded rod threadedly connected to the inner wall of the extension plate, a first arc-shaped limiting plate fixedly connected to the inner wall of the soundproof cover, sound-absorbing cotton provided inside the soundproof cover, a second arc-shaped limiting plate fixedly connected to the inner wall of the soundproof cover, and glass fiber provided between the first arc-shaped limiting plate and the second arc-shaped limiting plate.
[0006] The above technical solution, through the sound-absorbing cotton and glass fiber installed inside the soundproof cover, can effectively absorb and isolate the noise generated during motor operation, providing a quieter working environment. The soundproof cover can also protect the surface of the torque motor body. The through groove opened at the bottom of the fixed base plate helps to dissipate heat from the torque motor body and prevents damage to the torque motor body due to overheating.
[0007] As a further improvement to the above solution, the threaded rod passes through the extension plate and is threadedly connected to the inner wall of the fixed base plate.
[0008] The above technical solution uses threaded rods to fix the extension plate, thereby installing and securing the soundproof cover. It also facilitates subsequent disassembly and maintenance, making the operation simple and quick and improving its practicality.
[0009] As a further improvement to the above solution, two extension plates are provided, and the two extension plates are arranged in a circle around the soundproof cover.
[0010] The above technical solution improves the fixing effect of the soundproof cover by using two extension plates in conjunction with two threaded rods.
[0011] As a further improvement to the above solution, the torque motor body is located inside the soundproof enclosure.
[0012] As a further improvement to the above solution, multiple versions of both the first arc-shaped limiting plate and the second arc-shaped limiting plate are provided.
[0013] The above technical solution uses a first arc-shaped limiting plate in conjunction with a second arc-shaped limiting plate to install and limit the glass fiber, which is simple and quick to operate. At the same time, the glass fiber can be quickly removed, making it convenient to replace different sound insulation materials later.
[0014] As a further improvement to the above solution, the sound-absorbing cotton is located between the soundproof cover and the first arc-shaped limiting plate.
[0015] The above technical solution allows for the installation and positioning of sound-absorbing cotton by using the first arc-shaped limiting plate in conjunction with the inner wall of the soundproof cover, while also facilitating subsequent disassembly and replacement.
[0016] As a further improvement to the above solution, mounting holes are provided at the four corners of the fixed base plate.
[0017] The above technical solution involves using mounting holes and bolts to install and fix the base plate, thereby securing the torque motor body to its operating position.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This invention utilizes a soundproof cover, sound-absorbing cotton, and glass fiber. Specifically, glass fiber is a high-performance sound insulation material with excellent sound absorption and heat insulation properties, effectively insulating against noise. The sound-absorbing cotton is a porous material that effectively absorbs sound wave energy, reducing noise transmission and further enhancing the sound insulation effect. Through the dual sound insulation of sound-absorbing cotton and glass fiber, the noise generated by the torque motor during operation can be effectively absorbed and isolated, reducing noise pollution and providing a quieter working environment.
[0020] This utility model, by setting a first arc-shaped limiting plate and a second arc-shaped limiting plate, specifically uses the soundproof cover in conjunction with the first arc-shaped limiting plate to limit the installation of sound-absorbing cotton, and uses the first arc-shaped limiting plate in conjunction with the second arc-shaped limiting plate to limit the installation of glass fiber, which facilitates the quick removal of sound-absorbing cotton and glass fiber for replacement with different soundproofing materials, thus improving the convenience of use.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0029] Example:
[0030] Please combine Figure 1-5 This embodiment discloses a high-reliability, low-noise torque motor, including a fixed base plate 1. A torque motor body 2 is fixedly connected to the top of the fixed base plate 1. A through groove 3 is provided at the bottom of the fixed base plate 1. A soundproof cover 4 is provided at the upper end of the fixed base plate 1. An extension plate 5 is fixedly connected to the surface of the soundproof cover 4. A threaded rod 6 is threadedly connected to the inner wall of the extension plate 5. A first arc-shaped limiting plate 7 is fixedly connected to the inner wall of the soundproof cover 4. Sound-absorbing cotton 8 is provided inside the soundproof cover 4. A second arc-shaped limiting plate 9 is fixedly connected to the inner wall of the soundproof cover 4. The first arc-shaped limiting plate 7 and the second arc-shaped limiting plate 9... A glass fiber 10 is disposed between the two arc-shaped limiting plates 9. When the torque motor body 2 generates noise during operation, the glass fiber 10, being a high-performance sound insulation material with excellent sound absorption and heat insulation properties, effectively insulates the generated noise. The sound-absorbing cotton 8, being a porous material, can effectively absorb sound wave energy, reduce noise transmission, and further enhance the sound insulation effect. Through the double sound insulation of the sound-absorbing cotton 8 and the glass fiber 10, the noise generated during the operation of the torque motor body 2 can be effectively absorbed and isolated, reducing noise pollution and providing a quieter working environment.
[0031] The threaded rod 6 passes through the extension plate 5 and is threadedly connected to the inner wall of the fixed base plate 1. By disassembling the threaded rod 6, the fixation of the extension plate 5 can be removed, and the soundproof cover 4 can be disassembled and removed for subsequent inspection and maintenance.
[0032] There are two extension plates 5, which are arranged in a circle around the soundproof cover 4.
[0033] The torque motor body 2 is located inside the soundproof cover 4.
[0034] There are multiple first arc-shaped limiting plates 7 and multiple second arc-shaped limiting plates 9.
[0035] The sound-absorbing cotton 8 is located between the soundproof cover 4 and the first arc-shaped limiting plate 7. The soundproof cover 4, together with the first arc-shaped limiting plate 7, limits the installation of the sound-absorbing cotton 8. The first arc-shaped limiting plate 7, together with the second arc-shaped limiting plate 9, limits the installation of the glass fiber 10. This facilitates the quick removal of the sound-absorbing cotton 8 and the glass fiber 10 for replacement with different soundproofing materials, thus improving the convenience of use.
[0036] Mounting holes 11 are provided at the four corners of the fixed base plate 1, and the fixed base plate 1 is installed and fixed by the mounting blocks 11.
[0037] The implementation principle of a high-reliability, low-noise torque motor in this embodiment is as follows: When the torque motor body 2 generates noise during operation, the glass fiber 10, being a high-performance sound insulation material with excellent sound absorption and heat insulation properties, effectively absorbs the noise. The sound-absorbing cotton 8, a porous material, effectively absorbs sound wave energy, reduces noise propagation, and further enhances the sound insulation effect. Through the dual sound insulation of the sound-absorbing cotton 8 and glass fiber 10, the noise generated during the operation of the torque motor body 2 can be effectively absorbed and isolated, reducing noise pollution and providing a quieter working environment. When the torque motor body 2 needs maintenance, the soundproof cover 4 can be removed by disassembling the threaded rod 6 and canceling the fixation of the extension plate 5, facilitating subsequent maintenance. The soundproof cover 4, in conjunction with the first arc-shaped limiting plate 7, limits the installation of the sound-absorbing cotton 8, and the first arc-shaped limiting plate 7, in conjunction with the second arc-shaped limiting plate 9, limits the installation of the glass fiber 10, facilitating the quick removal of the sound-absorbing cotton 8 and glass fiber 10 for replacement with different sound insulation materials, thus improving the convenience of use.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
