[0002] As a crucial power source in industrial production, machinery manufacturing, power equipment, pump and fan systems, the operational stability and safety of electric motors are of paramount importance. However, electric motors often generate vibrations during operation, which not only affect their lifespan but can also disrupt the surrounding environment. Therefore, the research and application of motor vibration damping and fixing devices are of particular significance.

[0003] In related technologies, a vibration damping mechanism is usually installed below the motor to achieve a vibration reduction effect. However, since motors vary in size, weight, and vibration characteristics, traditional vibration damping fixing devices often need to be customized according to the specific specifications of the motor. This makes it difficult to adapt to motors of different sizes and specifications, resulting in poor versatility and high cost. Utility Model Content

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] The vibration-absorbing structure includes a main body and a support part installed on the main body. The support part has an arc-shaped surface for supporting the motor. The main body is located on the side of the support part that is away from the arc-shaped surface.

[0008] Two sets of position adjustment components are located on both sides of the body along the first horizontal direction, and the position adjustment components are connected to the support part.

[0009] Two sets of fixing components are provided, and the two sets of fixing components are set one-to-one with the two sets of position adjustment components. The fixing components include a connector, a first connecting part and a second connecting part. The connector is movably connected to the corresponding position adjustment component along the first horizontal direction. One end of the first connecting part is rotatably connected to the connector, and the other end of the first connecting part is hinged to the second connecting part. The end of the second connecting part on each side away from the first connecting part is detachably connected to the second connecting part on the other side.

[0010] Optionally, the position adjustment component includes:

[0012] The base plate is fixedly connected to the support.

[0013] The lead screw is rotatably connected to the base plate and extends along the first horizontal direction.

[0014] The nut is connected to the lead screw drive and is configured to reciprocate linearly along the first horizontal direction. The nut is fixed to the connecting plate.

[0015] Optionally, the position adjustment component also includes:

[0016] A connecting rod is fixedly connected to the base plate along the first horizontal direction;

[0017] The slider is sleeved on the outside of the connecting rod and slides with the connecting rod. The slider is fixedly connected to the connecting plate.

[0018] Optionally, the end of the lead screw away from the body is provided with a plurality of threaded holes spaced apart along its own radial direction, and a first fastener passes through the base plate and is threadedly connected to any of the threaded holes.

[0019] Optionally, the position adjustment component includes:

[0028] The beneficial effects of this utility model are:

[0029] The motor vibration damping and fixing device provided by this utility model features an arc-shaped support for the vibration-absorbing structure. This arc-shaped surface allows for better contact with the outer periphery of the motor, increasing the contact area between the vibration-absorbing structure and the motor. This results in a more uniform transmission of vibrations from the motor to the main body, dispersing vibration energy evenly. By setting position adjustment components and fixing components on both sides of the main body in the first horizontal direction, the position adjustment components allow for adjustment of the connecting member's position in the first horizontal direction. The connecting member moves the first connecting part, thereby adjusting the horizontal position of the fixing component. This allows for the application of motors of different specifications. After adjusting the first connecting part to the appropriate position, it will fit against the outer periphery of the motor. The second connecting parts on both sides then firmly hold and fix the motor. This enables vibration damping and fixing of motors of different specifications, offering strong versatility and eliminating the need for custom-designed vibration damping and fixing devices, significantly reducing manufacturing costs.

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] like Figure 1-5 As shown, an embodiment of this utility model provides a motor vibration damping and fixing device, including a vibration-absorbing structure 1, two sets of position adjustment components 3, and two sets of fixing components 4. The vibration-absorbing structure 1 includes a body 11 and a support portion 12 installed on the body 11. The support portion 12 has an arc-shaped surface for supporting the motor 2. The body 11 is located on the side of the support portion 12 facing away from the arc-shaped surface. The two sets of position adjustment components 3 are respectively located on both sides of the body 11 along a first horizontal direction and are connected to the support portion 12. The two sets of fixing components 4 are correspondingly arranged with the two sets of position adjustment components 3. The fixing components 4 include a connector 41, a first connecting portion 42, and a second connecting portion 43. The connector 41 is movably connected to the corresponding position adjustment component 3 along the first horizontal direction. One end of the first connecting portion 42 is rotatably connected to the connector 41, and the other end of the first connecting portion 42 is hinged to the second connecting portion 43. The end of the second connecting portion 43 on each side away from the first connecting portion 42 is detachably connected to the second connecting portion 43 on the other side. Specifically, the first horizontal direction is the length direction of the body.

[0041] The support portion 12 of the vibration-absorbing structure 1 is designed in an arc shape. The arc surface can better fit with the outer periphery of the motor 2, increasing the contact area between the vibration-absorbing structure 1 and the motor 2. This allows the vibration generated by the motor 2 to be transmitted to the body 11 more evenly, dispersing the vibration energy uniformly. By setting a position adjustment component 3 and a fixing component 4 on both sides of the body 11 in the first horizontal direction, the position adjustment component 3 can adjust the position of the connecting piece 41 in the first horizontal direction. The connecting piece 41 will drive the first connecting part 42 to move, thereby realizing the horizontal position adjustment of the fixing component 4, which can be used for motors 2 of different specifications. After the first connecting part 42 is adjusted to a suitable position, part of the first connecting part 42 will fit with the outer periphery of the motor 2. Then, the second connecting parts 43 on both sides are used to hold and fix the motor 2 tightly. This can realize vibration damping and fixing of motors 2 of different specifications, with strong versatility. There is no need to customize different types of vibration damping and fixing devices, which greatly reduces manufacturing costs.

[0042] It should be noted that the material of the vibration-absorbing structure 1 should be selected to have certain stiffness and damping characteristics to ensure stable support while having the ability to reduce vibration of the foundation, such as engineering plastics or alloy materials.

[0043] Furthermore, the position adjustment assembly 3 includes a connecting plate 31, a base plate 32, a lead screw 33, and a nut 34. The connecting plate 31 is fixedly connected to the connector 41, the base plate 32 is fixedly connected to the support 12, the lead screw 33 is rotatably connected to the base plate 32, the lead screw 33 extends along a first horizontal direction, the nut 34 is drively connected to the lead screw 33, the nut 34 is configured to reciprocate linearly along the first horizontal direction, and the nut 34 is fixed to the connecting plate 31.

[0044] Specifically, such as Figure 3 As shown, by manually rotating the lead screw 33, the lead screw 33 drives the nut 34 to move along the first horizontal direction. The nut 34 drives the connecting plate 31 to move along the first horizontal direction. The connecting plate 31 can adjust the horizontal position of the first connecting part 42, and then the motor 2 is clamped by the second connecting part 43, thereby enabling vibration damping and fixing of motors 2 of different specifications. Depending on the actual specifications of the motor 2, the lead screw 33 can be selectively rotated in the forward or reverse direction to fix the motor 2 in place. The method of using the lead screw 33 to drive the connecting plate 31 to move enables precise horizontal displacement adjustment.

[0045] Optionally, the position adjustment component 3 can also be equipped with a small motor. The small motor is mounted on the base plate 32, and the output end of the small motor is fixedly connected to the lead screw 33. By driving the lead screw 33 to rotate through the small motor, labor costs can be reduced and work efficiency can be improved.

[0046] In other embodiments, the position adjustment component 3 may also include a bracket, a rack and a gear. The bracket is fixedly connected to the support portion 12, the rack is slidably connected to the bracket and one end of the rack is connected to the connector 41. The rack extends along a first horizontal direction, and the gear is rotatably connected to the bracket and meshes with the rack.

[0047] By rotating the gear, the rack moves along the first horizontal direction. The rack moves, causing the connector 41 to move along the first horizontal direction. The connector 41 moves the first connecting part 42, making the horizontal position of the first connecting part 42 adjustable, thereby providing vibration damping and fixing for motors 2 of different specifications.

[0048] Furthermore, the position adjustment assembly 3 also includes a connecting rod 35 and a slider 36. The connecting rod 35 is fixedly connected to the base plate 32 along the first horizontal direction, and the slider 36 is sleeved on the connecting rod 35 and slides with the connecting rod 35. The slider 36 is fixedly connected to the connecting plate 31.

[0049] like Figure 3 As shown, there are two connecting rods 35, each of which is equipped with a slider 36. The connecting rod 35 is fixed to the base plate 32, and the slider 36 is fixed to the connecting plate 31. The connecting rod 35 and the slider 36 provide support and guidance for the connecting plate 31. At the same time, the connecting rod 35 and the slider 36 can ensure that the nut 34 reciprocates only in a straight line along the first horizontal direction.

[0050] Furthermore, the end of the lead screw 33 furthest from the body 11 is provided with a plurality of threaded holes spaced apart along its own radial direction, and a first fastener passes through the base plate 32 and is threadedly connected to any of the threaded holes. Specifically, the first fastener is a bolt.

[0051] like Figure 4 As shown, after the connecting plate 31 is adjusted to a suitable position by rotating the lead screw 33, the first fastener passes through the base plate 32 and is threadedly connected to the lead screw 33, which can fix the horizontal position of the connecting plate 31 relatively. When it is necessary to replace the motor 2 of a different specification, the first fastener is loosened to allow the connecting plate 31 to move along the first horizontal direction, adjust it to a suitable position, and then fix it with the first fastener.

[0052] Furthermore, the first connecting part 42 includes a plurality of connecting frames 421, which are hinged together end to end in sequence.

[0053] like Figure 5 As shown, multiple connecting brackets 421 are hinged together, which allows the first connecting part 42 to fit more closely to the outer periphery of the motor 2, increasing the contact area between the first connecting part 42 and the motor 2 and improving the fixing stability of the motor 2.

[0054] Furthermore, the second connecting part 43 includes a plurality of connecting strips 431, which are bent and connected sequentially along the circumference of the motor 2.

[0055] Multiple connecting strips 431 are bent in sequence to form an approximately arc-shaped structure, which can increase the contact area between the second connecting part 43 and the motor 2. The combination of the first connecting part 42 and the second connecting part 43 can hold the entire motor 2 tightly and fix it, further improving the fixation stability of the motor 2.

[0056] Furthermore, each second connecting part 43 is provided with multiple through holes on the connecting strip 431 away from the corresponding first connecting part 42. The multiple through holes are distributed at intervals along the length direction of the corresponding connecting strip 431. The multiple through holes on the two second connecting parts 43 are aligned one by one, and the second fastener passes through any of the aligned through holes in sequence.

[0057] By providing multiple through holes on the connecting strip 431 away from the first connecting part 42, the second connecting part 43 can be tightly connected to the motor 2 according to different specifications of the motor 2, and then fixed by passing the second fastener through the appropriate through holes. This prevents the motor vibration damping fixing device from loosening due to vibration during the operation of the motor 2, thereby improving the stability of the motor 2.

[0058] The end of the second connecting part 43 adopts a snap-lock design, which can adapt to motors 2 of different specifications, improving versatility and flexibility.

[0059] In other embodiments, one of the second connecting portions 43 may be provided with multiple through holes in the connecting strip 431 away from the corresponding first connecting portion 42, and the other second connecting portion 43 may be provided with a protrusion in the connecting strip 431 away from the corresponding first connecting portion 42, and the protrusion may pass through any of the through holes.

[0060] Furthermore, the motor vibration damping fixing device also includes a counterweight, which is detachably installed on the main body 11.

[0061] By setting counterweights on the main body 11, the mass of the entire motor vibration damping and fixing device can be increased. This allows the motor vibration damping and fixing device to better resist external vibrations due to inertia when subjected to the vibration of the motor 2, thereby reducing the vibration amplitude. The installation method that combines the vibration absorption structure 1 with the counterweights can effectively reduce the mechanical vibration generated by the motor 2 during operation, improve the stability of equipment operation, and extend the service life of the equipment.

[0062] Optionally, the counterweight is an optional counterweight block. The mass of the counterweight block should be optimized according to the vibration characteristics of the motor 2, and is usually 5%-15% of the mass of the motor 2. Different masses of counterweight blocks can be selected according to different specifications of the motor 2.

[0063] In other embodiments, the motor vibration damping fixing device further includes a dynamic vibration absorber, which is detachably mounted on the body 11.

[0064] By setting a dynamic vibration absorber on the main body 11, when the motor 2 vibrates, the dynamic vibration absorber will generate an anti-phase motion, that is, generate a reaction force opposite to the vibration direction of the motor 2, thereby offsetting part of the vibration force generated by the motor 2 and achieving the vibration reduction effect. The installation method of combining the vibration absorption structure 1 with the dynamic vibration absorber can effectively reduce the mechanical vibration generated by the motor 2 during operation, improve the stability of equipment operation, and extend the service life of the equipment.

[0065] It should be noted that the parameters of the dynamic vibration absorber should be tuned according to the main vibration frequency of motor 2 in order to obtain the best vibration reduction effect. The parameter tuning of the dynamic vibration absorber is an existing technology and will not be discussed in detail here.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
