Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor vibration damping device. Background Technology

[0002] Electric motors, as devices that convert electrical energy into mechanical energy, are widely used in many fields. During operation, motors vibrate due to rotor imbalance, electromagnetic forces, and bearing wear. Motor vibration can lead to a series of adverse effects, such as loosening and accelerated wear of motor components, shortening the motor's lifespan; the noise generated by vibration can also cause noise pollution in the working environment, affecting the physical and mental health of operators; at the same time, vibration may affect the output accuracy of the motor, leading to a decrease in the operating accuracy of the equipment it drives, thus affecting product quality. Therefore, vibration reduction measures are necessary for motors.

[0003] In existing technologies, vibration sources can be reduced in some cases during the motor manufacturing stage by optimizing rotor balance and improving support structures. However, this usually requires customized design for a specific motor, resulting in high costs and limited adaptability. Additionally, elastic supports or vibration damping pads can be used during motor installation to reduce the transmission of vibration energy. However, this method has limited effectiveness for higher frequency vibrations and may lead to aging or stiffness changes over long-term use, affecting vibration reduction performance. The natural frequency of the system can also be adjusted by adding external mass blocks, dampers, or dynamic vibration absorbers to reduce resonance effects. However, traditional installation methods typically require modifications to the motor housing, such as drilling and welding, which not only increases installation complexity but may also affect the structural integrity and heat dissipation performance of the motor. Utility Model Content

[0004] The purpose of this utility model is to provide a motor vibration damping device to solve the technical problems of poor adaptability and high cost of existing motor vibration damping devices.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A motor vibration damping device is applied to a horizontal motor, the horizontal motor including a motor body, and a plurality of ribs are arranged at intervals along the circumference of the motor body. The motor vibration damping device includes:

[0007] Two clamping members are arranged opposite to each other. Each clamping member includes a clamping plate and a connecting plate and a plug-in plate respectively disposed at both ends of the clamping plate. The two clamping plates can clamp the two sides of the motor body. The plug-in plate can be inserted between two adjacent ribs to fix the clamping plate.

[0008] Mounting base, the mounting base is disposed between the two clamping members, and the two ends of the mounting base are detachably connected to the two connecting plates respectively;

[0009] A vibration damper is detachably connected to the mounting base.

[0010] Preferably, the clamping plate extends obliquely from top to bottom in a direction away from the motor body, and the plug-in plate and the clamping plate are arranged at an angle.

[0011] Preferably, the included angle between the plug-in plate and the clamping plate is greater than or equal to 45 degrees and less than or equal to 90 degrees.

[0012] Preferably, the connection between the mounting base and the connecting plate is a bolt connection, a pin connection, or a snap-fit ​​connection.

[0013] Preferably, a vibration damping spring is provided between the mounting base and the connecting plate.

[0014] Preferably, the vibration damping element is a mass block.

[0015] Preferably, the vibration damping component is a dynamic vibration absorber.

[0016] Preferably, the plug-in plate is provided with a magnetic absorbing piece, which is magnetically connected to the rib.

[0017] Preferably, the length of the clamping plate is adjustable.

[0018] Preferably, the clamping plate is provided with a vibration damping pad on the side near the motor body.

[0019] The beneficial effects of this utility model are:

[0020] This invention proposes a motor vibration damping device that uses two opposing clamping members as the basic fixing unit. The clamping plates non-invasively clamp the motor body on both sides, avoiding the damage to the motor structure caused by traditional welding or drilling installation methods, effectively ensuring the integrity of the motor structure. The plug-in plates at both ends of the clamping members form a limiting position by inserting into the gap between adjacent ribs, thereby fixing the clamping plates. The ribs themselves act as anti-torsional support points, enhancing the connection stability between the clamping plates and the motor. The plug-in fixing method eliminates the need for additional processing of the motor body, simplifying the installation process and improving the device's adaptability to different motors. The mounting base is located between the two clamping members and is detachably connected to the connecting plate, making the assembly of the entire device more flexible and convenient for installation and subsequent maintenance and replacement. When the horizontal motor vibrates during operation, the vibration is transmitted from the motor body to the clamping plates through the plug-in plates. Since the clamping plates are fixed to the motor body, the vibration is transmitted to the mounting base. The vibration damping member, detachably connected to the mounting base, possesses buffering and energy absorption characteristics. When vibration energy is transmitted to the damping component, the damping component dissipates the mechanical energy of the vibration into other forms of energy through its own elastic deformation and internal damping, thereby reducing the transmitted vibration amplitude and effectively attenuating the motor vibration. In summary, this motor vibration damping device utilizes a structural design that features a rib-fixed clamping plate, a detachable connection between the mounting base and the clamping component, and a detachable mounting of the damping component on the mounting base. This design achieves stable installation, flexible assembly, and easy replacement of the damping component, effectively improving the motor vibration damping effect and convenience, and possessing good practicality and adaptability.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1 and Figure 2 The motor vibration damping device provided in this embodiment is applied to a horizontal motor. The horizontal motor includes a motor body 100, and a plurality of ribs 101 are arranged at intervals along the circumference of the motor body 100. The motor vibration damping device includes two clamping members 1, a mounting base 2, and a damping member arranged opposite to each other. The clamping member 1 includes a clamping plate 11 and a connecting plate 12 and a plug-in plate 13 respectively disposed at both ends of the clamping plate 11. The two clamping plates 11 can clamp the two sides of the motor body 100, and the plug-in plate 13 can be inserted between two adjacent ribs 101 to fix the clamping plate 11. The mounting base 2 is disposed between the two clamping members 1, and both ends of the mounting base 2 are detachably connected to the two connecting plates 12 respectively. The damping member is detachably connected to the mounting base 2.

[0030] The motor vibration damping device proposed in this utility model uses two opposing clamping members 1 as basic fixing units. The clamping plates 11 non-invasively clamp both sides of the motor body 100, avoiding the damage to the motor structure caused by traditional welding or drilling installation methods, effectively ensuring the integrity of the motor structure. The plug-in plates 13 at both ends of the clamping members 1 form a limiting position by inserting into the gap between adjacent ribs 101, thereby fixing the clamping plates 11. The ribs 101 themselves serve as anti-torsional support points, enhancing the connection stability between the clamping plates 11 and the motor. The plug-in fixing method using the plug-in plates 13 eliminates the need for additional processing of the motor body 1, simplifying the installation process and improving the device's adaptability to different motors. The mounting base 2 is located between the two clamping members 1 and is detachably connected to the connecting plate 12, making the assembly of the entire device more flexible and convenient for installation and subsequent maintenance and replacement. When the horizontal motor vibrates during operation, the vibration is transmitted from the motor body 100 to the clamping plates 11 through the plug-in plates 13. Since the clamping plates 11 are fixed to the motor body 100, the vibration is transmitted to the mounting base 2. The vibration damper is detachably connected to the mounting base 2 and possesses buffering and energy absorption characteristics. When vibration energy is transmitted to the vibration damper, the damper dissipates the mechanical energy of the vibration into other forms of energy through its own elastic deformation and internal damping, thereby reducing the transmitted vibration amplitude and effectively attenuating the motor vibration. In summary, this motor vibration damping device utilizes the structural design of the rib 101 fixing the clamping plate 11, the detachable connection between the mounting base 2 and the clamping component 1, and the detachable installation of the vibration damper on the mounting base 2. This design achieves stable installation, flexible assembly, and easy replacement of the vibration damper, effectively improving the motor vibration damping effect and convenience, and possessing good practicality and adaptability.

[0031] The specific structure of the motor vibration damping device is described below.

[0032] Specifically, the clamping plate 11 extends at an angle from top to bottom away from the motor body 100, which can better fit the shape of the motor body 100, making the contact between the clamping plate 11 and the motor body 100 tighter and more stable, enhancing the clamping force, and thus more effectively preventing the clamping part 1 from loosening or shifting during motor operation; the plug-in plate 13 and the clamping plate 11 are set at an angle, which helps to make more reasonable use of the space around the motor body 100 in a limited space to arrange the plug-in structure of the plug-in plate 13 and the rib 101, further improving the compactness and stability of the entire device installation.

[0033] More specifically, the included angle between the plug plate 13 and the clamping plate 11 is greater than or equal to 45 degrees and less than or equal to 90 degrees. This ensures that when the plug plate 13 is inserted between the ribs 101, it forms a suitable mating angle with the ribs 101. This ensures that the plug plate 13 is securely inserted between the ribs 101, enhancing the fixing effect of the entire clamping component 1 on the motor body 100 and effectively preventing shaking caused by an insufficiently small angle. At the same time, it avoids the plug plate 13 being difficult to insert between the ribs 101 due to an excessively large angle, or occupying too much space and affecting the overall layout of the motor.

[0034] For example, the included angle between the plug-in plate 13 and the clamping plate 11 can be 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees or 85 degrees, etc., and can be adjusted according to the actual working conditions. No limitation is made here.

[0035] To further improve the stability of the clamping plate 11, a magnetic absorbing piece is provided on the plug-in plate 13, which is magnetically connected to the rib 101. The magnetic connection enhances the stability of the connection between the plug-in plate 13 and the rib 101, and can effectively prevent the plug-in plate 13 from loosening and falling out from between the ribs 101 even when the motor body 100 vibrates during operation, making the clamping member 1 more reliably fixed to the motor body 100.

[0036] Since the dimensions of the motor body 100 vary depending on the model, the length of the clamping plate 11 is adjustable to improve the adaptability of the motor vibration damping device, thereby flexibly adapting to various specifications of motor body 100 and meeting diverse usage needs.

[0037] For example, the clamping plate 11 includes an inner plate and an outer plate that are nested together, with the inner plate sliding within the outer plate. The outer plate has a plurality of positioning holes spaced apart along its length, and the inner plate has corresponding through holes at corresponding positions. When the length of the clamping plate 11 needs to be adjusted, the inner plate is slid out or in to a suitable position from the outer plate, and then positioning pins are sequentially passed through the through holes in the inner plate and the corresponding positioning holes in the outer plate to fix the inner and outer plates relative to each other, thereby adjusting the length of the clamping plate 11 to accommodate motor bodies 100 of different sizes.

[0038] In other embodiments, the clamping plate 11 may be composed of multiple modular plates of the same or different lengths, each modular plate having a matching connection structure at both ends, such as a slot at one end and a block at the other. Based on the dimensions of the motor body 100, a suitable number of modular plates are selected, and the blocks are inserted into the slots to assemble the clamping plate 11 of the required length.

[0039] Optionally, a vibration damping pad is provided on the side of the clamping plate 11 closest to the motor body 100. The vibration damping pad can buffer the vibration generated during the operation of the motor body 100, reducing the direct transmission of vibration to the clamping plate 11 and improving the vibration damping effect. Furthermore, the vibration damping pad can prevent direct rigid contact between the clamping plate 11 and the rib 101, preventing wear or scratches on the surface of the motor body 100 caused by vibration during long-term use, thus protecting the integrity of the motor body 100. In addition, the vibration damping pad can fill any small gaps that may exist between the clamping plate 11 and the motor body 100, making the clamping tighter and more stable.

[0040] Among them, vibration damping pads can be rubber pads, silicone pads, etc., which will not be elaborated here.

[0041] A connecting plate 12 is provided at the upper end of the clamping plate 11 for connecting the mounting base 2. Specifically, the connection between the mounting base 2 and the connecting plate 12 can be a bolt connection, a pin connection, or a snap-fit ​​connection. Bolt connections offer high connection strength and stability, capable of withstanding various forces generated during motor operation, ensuring a tight fit between the mounting base 2 and the connecting plate 12, preventing loosening and guaranteeing the reliability of the entire vibration damping device. Furthermore, adjusting the tightening of the bolts allows for fine-tuning of the relative position between the mounting base 2 and the connecting plate 12, improving the installation accuracy. Pin connections are simple and convenient to operate, with rapid installation and disassembly. When maintenance, component replacement, or layout adjustments are required, the mounting base 2 and the connecting plate 12 can be quickly separated, improving maintenance efficiency. Snap-fit ​​connections feature rapid installation and disassembly, requiring no additional tools and can be performed by hand, enhancing on-site installation convenience.

[0042] It is understandable that in actual use, the required connection method can be selected according to different usage scenarios and needs, and no restrictions are imposed here.

[0043] Optionally, a damping spring is provided between the mounting base 2 and the connecting plate 12. When the motor body 100 is running, part of the vibration generated will be transmitted to the connecting plate 12 through the clamping member 1. The damping spring can buffer and absorb this part of the vibration, reduce the intensity of the vibration transmitted to the mounting base 2, and further improve the vibration reduction effect of the motor vibration damping device.

[0044] A vibration damper is mounted on the mounting base 2 to dampen the vibration of the motor body 100. In this embodiment, the vibration damper is a mass block. When the motor body 100 operates, it vibrates, and the mass block reacts to this vibration due to its inertia. The vibration of the motor body 100 attempts to move the mass block along with it, but the mass block, due to its mass, resists this tendency. The inertial force of the mass block interacts with the force of the vibration of the motor body 100, changing the dynamic characteristics of the vibration system and thus achieving a vibration damping effect. As a vibration damper, the mass block has a simple structure, requires no complex manufacturing process, reduces production costs and manufacturing difficulty, and also facilitates later maintenance and replacement.

[0045] In some embodiments, the vibration damping component is a dynamic vibration absorber. The dynamic vibration absorber includes a gravity block, a telescopic spring, and a damper. When the motor body 100 vibrates during operation, the natural frequency of the dynamic vibration absorber is designed to be close to the main vibration frequency of the motor. When the motor vibrates, the dynamic vibration absorber generates vibration in the opposite direction to the motor's vibration. For example, if the motor vibrates upwards, the dynamic vibration absorber, under the action of its telescopic spring and gravity block, generates downward vibration; the two vibrations cancel each other out, thereby reducing the vibration amplitude of the motor body 100. Simultaneously, the damper dissipates vibration energy, further suppressing vibration and avoiding the adverse effects of resonance. The dynamic vibration absorber can automatically adjust according to changes in the vibration frequency of the motor body 100. When the motor body 100 operates under different conditions, its vibration frequency may change. The dynamic vibration absorber can track these changes in real time and adjust its own vibration frequency through an internal adjustment mechanism to always maintain a match with the vibration frequency of the motor body 100, ensuring good vibration reduction under various operating conditions and improving the adaptability of the motor vibration damping device to different working scenarios.

[0046] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
