Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically, it relates to a shock absorption component. Background Technology

[0002] When two components require a vibration-damping connection, vibration damping components are usually used to absorb and disperse the vibration energy of the mechanical equipment, thereby reducing the noise generated during equipment operation. At the same time, they can prevent the connection from loosening or falling off, thus protecting the equipment from damage and extending its service life.

[0003] There are various types of existing vibration damping components, among which the two-piece rubber pad assembly is the most widely used. For example... Figure 1 As shown, this two-piece rubber pad assembly 100 typically includes upper and lower rubber pads 110 and 120. The upper rubber pad 110 is typically designed as an annular shape, with a through hole 111 formed in the inner ring for inserting a connecting bolt 130. Figure 2 As shown, the outer ring diameter is larger than the diameter of the mounting hole of the first component 141 requiring vibration damping. In use, it can be placed on the top surface of the first component 141, positioned between the first component 141 and the bolt head of the bolt 130, to absorb and disperse the vibration generated between the bolt head (or the washer 131 mounted on the bolt 130) and the first component 141. The lower rubber pad 120 is typically designed in a T-shape, including a damping portion 121 and an insertion portion 122. Both the damping portion 121 and the insertion portion 122 are annular, with the inner ring forming a through hole 123 for the bolt 130 to be inserted. The insertion portion 122 is used to insert into the mounting hole of the first component 141. The damping portion 121 can be arranged between the first component 141 and the second component 142 to absorb and disperse the vibration generated between them.

[0004] In actual installation, the insertion part 122 of the lower rubber pad 120 is usually installed into the assembly hole of the first component 141 first. Then, the washer 131 and the upper rubber pad 110 are installed on the bolt 130, and then the bolt 130 is inserted into the assembly hole of the first component 141. At this time, it often happens that the bolt 130 pushes the insertion part 122 of the lower rubber pad 120 out of the assembly hole of the first component 141, resulting in installation failure and affecting the assembly speed.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] This invention addresses the aforementioned problems in the prior art by proposing an easy-to-install shock-absorbing component to accelerate the assembly speed between parts.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] In one aspect, this utility model proposes an easy-to-install shock-absorbing assembly for installation between two components requiring shock absorption, comprising a split first shock-absorbing pad and a second shock-absorbing pad; wherein, the first shock-absorbing pad includes a shock-absorbing part, an insertion part, and a stop part; the shock-absorbing part is annular, and the outer radius of the annular part is larger than the radius of the assembly hole of the component; the insertion part is annular and is installed on the shock-absorbing part for insertion into the assembly hole of the component; the stop part is disposed on the insertion part for passing through the assembly hole of the component and abutting against the surface of the component surrounding the assembly hole; the second shock-absorbing pad is annular, and a recessed stop part clearance area is formed on one end face of it for accommodating the stop part of the first shock-absorbing pad.

[0009] In some embodiments of this application, to facilitate the stop portion passing through the assembly hole of the component, the stop portion of the first shock-absorbing pad can be designed as a frustum with a through hole, and the bottom surface of the stop portion is mounted on the insertion portion; the bottom radius of the stop portion is configured to be larger than the radius of the assembly hole of the component, while the top radius is smaller than the radius of the assembly hole of the component, so as to minimize the contact area between the stop portion and the assembly hole of the component and reduce the frictional resistance during insertion; the through hole is configured to penetrate the top and bottom surfaces of the stop portion and be coaxial with the central axis of the stop portion, so that the screw can pass through it.

[0010] In some embodiments of this application, the through hole of the stop portion can be configured to be concentric with the inner ring of the damping portion and the insertion portion and have the same radius, and smaller than the radius of the assembly hole of the component; at the same time, the bottom radius of the stop portion can be configured to be larger than the outer ring radius of the insertion portion, so as to reliably stop the component on the surface surrounding its assembly hole.

[0011] In some embodiments of this application, the shape and size of the stop portion of the second shock absorber can be configured to match the outer contour shape and size of the stop portion of the first shock absorber, so as to improve the tightness of the assembly of the first shock absorber and the second shock absorber, and ensure that the second shock absorber can fit tightly with the component to achieve the best shock absorption effect.

[0012] In some embodiments of this application, steel sleeves may be further inserted into the inner rings of the damping portion and the insertion portion, as well as the through holes of the stop portion, to prevent the bolts from being tightened and crushing the first damping pad. Simultaneously, the steel sleeves may be configured to have an interference fit with the inner rings of the damping portion and the insertion portion, as well as the through holes of the stop portion, to prevent the steel sleeves from falling out of the first damping pad.

[0013] In some embodiments of this application, the steel sleeve can be configured to insert into the inner ring of the second damping pad when the second damping pad is installed on the first damping pad, to prevent the bolts from being tightened and crushing the second damping pad. Simultaneously, the inner ring radius of the second damping pad can be configured to be equal to the inner ring radius of the damping portion of the first damping pad, thereby achieving an interference fit between the steel sleeve and the inner ring of the second damping pad, ensuring the secure assembly of the steel sleeve and the second damping pad.

[0014] In some embodiments of this application, the height of the steel sleeve can be configured to be less than the overall height of the first and second shock-absorbing pads after assembly, to prevent the steel sleeve from being exposed and affecting the shock absorption effect.

[0015] In some embodiments of this application, the bottom radius of the stop portion can be configured to be 1mm to 3mm larger than the radius of the assembly hole of the component. This ensures that the stop portion can pass smoothly through the assembly hole and forms an effective abutment on the surface of the component surrounding the assembly hole.

[0016] In some embodiments of this application, the outer ring radius of the damping portion of the first damping pad can be configured to be equal to the outer ring radius of the second damping pad, and more than 5 mm larger than the radius of the assembly hole of the component, so as to form an effective gap between the two components and the washer fitted on the bolt.

[0017] In another aspect, this utility model also proposes a vibration damping component mounting structure, including a first vibration damping pad, a second vibration damping pad, bolts, and washers; wherein,

[0018] The first shock-absorbing pad includes:

[0019] The shock-absorbing part is ring-shaped and is assembled between the first and second components that require shock absorption connection, and the radius of the outer ring is larger than the radius of the assembly hole of the first component.

[0020] An insert, which is annular, is mounted on the shock-absorbing part and inserted into the assembly hole of the first component;

[0021] A stop portion is provided on the insertion portion, passes through the mounting hole of the first component, and abuts against the surface of the component surrounding the mounting hole;

[0022] The second shock-absorbing pad is annular and is positioned on opposite sides of the first component, along with the shock-absorbing portion of the first shock-absorbing pad; a recessed stop clearance area is formed on one end face of the second shock-absorbing pad, and the stop portion of the first shock-absorbing pad is installed within the stop clearance area;

[0023] The bolt passes through the second damping pad and the first damping pad in sequence and is threadedly connected to the second component.

[0024] In some embodiments of this application, steel sleeves may be further provided in the inner annular holes of the first and second damping pads to prevent the bolts from being tightened and crushing the first and second damping pads; a washer may be further fitted on the bolt and assembled between the bolt head and the second damping pad to increase the contact area and improve the assembly effect between the bolt and the second damping pad.

[0025] Compared with the prior art, the advantages and positive effects of this utility model are mainly reflected in:

[0026] 1. This utility model designs the shock-absorbing component as a two-piece split structure, which simplifies its installation on components. By designing an insertion part and a stop part on one of the shock-absorbing pads, the firmness of the shock-absorbing pad in the assembly hole of the component can be improved. Even if the shock-absorbing pad is touched or squeezed when the bolt is inserted, it will not fall out of the assembly hole, thereby ensuring the smooth connection of shock absorption between components and improving assembly speed and work efficiency.

[0027] 2. By adding a steel sleeve to the shock absorber assembly, this utility model can effectively prevent the shock absorber assembly from being crushed by tightening the bolts, thereby protecting the shock absorber assembly and extending its service life.

[0028] 3. The shock-absorbing component of this utility model can be made of common elastic materials such as rubber, which is simple to mold, low in cost, and easy to promote and apply.

In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0044] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0045] like Figure 3 As shown, the shock absorption component 200 in this embodiment is preferably designed as a two-piece split structure for easy installation, mainly including a first shock absorption pad 210 and a second shock absorption pad 220. Both the first shock absorption pad 210 and the second shock absorption pad 220 are made of elastic materials such as rubber and silicone to achieve the shock absorption effect of absorbing and dispersing vibration energy.

[0046] In some embodiments, a damping portion 211, an insertion portion 212, and a stop portion 213 may be configured in the first damping pad 210.

[0047] The damping part 211 can be designed as a ring, with the outer and inner ring dimensions of the damping part 211 configured according to the dimensions of the mounting holes on the two components connected by the damping connection. In some embodiments, combined with Figure 8 As shown, for the case where the mounting hole 143 on the component is a round hole, the shock absorber 211 can be specifically designed to be annular, with the outer ring radius being larger than the radius of the mounting hole 143 and the inner ring radius being smaller than the radius of the mounting hole 143.

[0048] The insertion part 212 is used to be inserted into the assembly hole 143 of the component. It can be designed as a ring and installed on the damping part 211, for example, on the top surface 215 of the damping part 211, and extends perpendicular to the top surface 215 of the damping part 211 in a direction away from the top surface of the damping part 211.

[0049] In some embodiments, when the mounting hole 143 on the component is a circular hole, the insertion part 212 can be specifically designed to be annular, with its outer ring radius being smaller than the radius of the mounting hole 143, to facilitate the insertion of the insertion part 212 into the mounting hole 143. Alternatively, the insertion part 212 can be designed to have an interference fit with the mounting hole 143 to improve the stability of the insertion part 212 installed in the mounting hole 143. Simultaneously, the inner ring of the insertion part 212 is configured to be concentric and have the same radius as the inner ring of the shock-absorbing part 211, so that the wall of the inner ring hole 214 formed by the inner ring is flat and smooth, facilitating the insertion or passage of other components.

[0050] The stop portion 213 is provided on the insertion portion 212, for example, on the top surface of the insertion portion 212, for passing through the assembly hole 143 of the component and abutting against the surface of the component surrounding the assembly hole 143, thereby securing the first shock-absorbing pad 210 in the assembly hole 143 and preventing it from falling off during subsequent assembly.

[0051] To facilitate the stop portion 213 passing through the assembly hole 143 of the component and achieving a snap-fit ​​locking position on the component, in some embodiments, the stop portion 213 can be designed as a frustum shape, combined with... Figure 3 , Figure 4 As shown. The base radius of the frustum is slightly larger than the outer circumference of the mounting hole 143 and the insertion portion 212 of the component. For example, the base radius of the frustum is 1mm to 3mm larger than the radius of the mounting hole 143 of the component; and the top radius of the frustum is smaller than the radius of the mounting hole 143 of the component. The bottom surface of the stop portion 213 is mounted on the top surface of the insertion portion 212, and the top surface of the stop portion 213 is positioned away from the insertion portion 212. Since the base radius of the stop portion 213 is larger than the outer circumference of the insertion portion 212, a boss is formed relative to the insertion portion 212, which, after passing through the mounting hole 143, can be engaged with the surface of the component surrounding the mounting hole 143. Meanwhile, since the top surface radius of the stop 213 is smaller than the radius of the mounting hole 143 of the component, the contact area between the stop 213 and the mounting hole 143 is small during the period when the stop 213 passes through the mounting hole 143, and the frictional resistance generated is not large. Furthermore, since the stop 213 has the characteristic of elastic deformation, it can easily pass through the mounting hole 143.

[0052] A through hole is made in the stop portion 213, penetrating both the top and bottom surfaces of the stop portion 213. This through hole is coaxial with the central axis of the stop portion 213 and concentric with and of equal radius to the inner ring of the damping portion 211 and the insertion portion 212. This forms an inner ring hole 214 on the first damping pad 210, with a flat wall and a certain height, extending vertically. Figure 4 As shown.

[0053] In some embodiments, the first shock-absorbing pad 210 can be designed to be integrally formed, and the inner ring hole 214 can be formed by stamping in one step to simplify the manufacturing process.

[0054] The second shock-absorbing pad 220 can be designed in a ring shape, such as Figure 3 As shown, for example, it can be designed as an annular shape with the same size as the damping portion 211 in the first damping pad 210. On one end face 221 of the second damping pad 220, such as the bottom surface of the second damping pad 220, a stop portion clearance area 222 recessed into the end face 221 is formed, combined with Figure 5 , Figure 6 As shown, a stop portion 213 is used to accommodate the first shock-absorbing pad 210.

[0055] In some embodiments, the shape and size of the stop clearance area 222 can be designed to match the shape and size of the outer contour of the stop portion 212 of the first damping pad 210. That is, the stop clearance area 222 is also frustum-shaped, and the larger radius bottom surface of the frustum is formed on the end face 221 of the second damping pad 220, while the smaller radius top surface of the frustum is closer to the other end face 224 of the second damping pad than its bottom surface. With this structural design, when the first damping pad 210 and the second damping pad 220 are installed on opposite sides of the component, not only can the second damping pad 220 be ensured to fit against one side surface of the component, but the stop portion 213 of the first damping pad 210 can also assist in the rapid positioning of the second damping pad 220 on the component, so that the central axis of the inner ring hole 214 of the first damping pad 210 is quickly aligned with the central axis of the inner ring hole 223 of the second damping pad 220, simplifying the assembly operation. Meanwhile, by configuring the stop portion avoidance area 222 of the second damping pad 220 to be tightly assembled with the stop portion 213 of the first damping pad 210 to form an integral unit, the displacement of the second damping pad 220 on the surface of the component can be avoided, thereby obtaining a better damping effect.

[0056] The outer ring radius of the damping part 211 of the first damping pad 210 and the outer ring radius of the second damping pad 220 are more than 5mm larger than the radius of the mounting hole 143 of the component. Figure 8 As shown, this is to enable an effective gap to be formed between the two components 141 and 142 that require a shock-absorbing connection, and between one of the components 141 and the washer 131 fitted on the bolt 130.

[0057] To prevent the bolt 130 from tightening and crushing the damping assembly 200 after insertion, this embodiment also includes a steel sleeve 230 within the damping assembly 200. Figure 7 As shown.

[0058] In some embodiments, the steel sleeve 230 can be designed as a cylindrical tubular structure, and the radius r of the steel sleeve 230 can be configured to be slightly larger than the radius of the inner annular hole 214 of the first damping pad 210 and the radius of the inner annular hole 223 of the second damping pad 220. This allows the steel sleeve 230 to have an interference fit with the inner annular holes 214 and 223 of the first and second damping pads 210 and 220 when it is inserted into them, thereby improving the stability of the assembly of the steel sleeve 230 with the first and second damping pads 210 and 220.

[0059] The height h of the steel sleeve 230 is less than the overall height H of the first damping pad 210 and the second damping pad 220 after assembly, such as Figure 9 As shown, this ensures that the first damping pad 210 and the second damping pad 220 can be normally compressed and deformed in the height direction of the steel sleeve 230, without being affected by the steel sleeve 230. At the same time, it also prevents the two components 141 and 142 of the damping connection from contacting the steel sleeve 230 during vibration, thus affecting the damping effect.

[0060] Industrial applicability

[0061] The specific installation structure of the shock absorption component in this embodiment is described in detail below.

[0062] When it is necessary to install the first component 141, which absorbs vibration, onto the second component 142, such as Figure 8 As shown, the insertion part 212 and the stop part 213 of the first damping pad 210 can be inserted into the mounting hole 143 of the first component 141 firstly, and the stop part 213 of the first damping pad 210 can be made to pass through the mounting hole 143 and abut against the upper surface of the first component 141, as shown. Figure 9 As shown. At this time, the top surface 215 of the damping part 211 of the first damping pad 210 is in contact with the lower surface of the first component 141.

[0063] The second damping pad 220 is installed on the upper surface of the first component 141, and the stop portion 213 of the first damping pad 210 is inserted into the stop portion clearance area 222 of the second damping pad 220. At this time, the end face 221 of the second damping pad 220 forming the stop portion clearance area 222 is in contact with the upper surface of the first component 141.

[0064] A steel sleeve 230 is inserted into the inner annular holes 214 and 223 of the first damping pad 210 and the second damping pad 220. Then, a washer 131 is fitted onto the bolt 130. Next, the bolt 130 is passed sequentially through the inner annular hole 223 of the second damping pad 220, the steel sleeve 230, and the inner annular hole 214 of the first damping pad 210, and after extending out of the first damping pad 210, it is inserted into the mounting hole 144 on the second component 142.

[0065] Tighten bolt 130 to complete the vibration-damping connection between the first component 141 and the second component 142. At this time, the washer 131 presses against the other end face 224 of the second damping pad 220, and the bottom surface 216 of the damping part 211 of the first damping pad 210 presses against the second component 142. Since the second damping pad 220 is arranged between the washer 131 and the first component 141, and the first damping pad 210 is arranged between the first component 141 and the second component 142, the first damping pad 210 and the second damping pad 220 form an elastic isolation between the two adjacent metal parts, thereby absorbing and dispersing the vibration energy generated by the bolt 130 and components 141 and 142, eliminating vibration noise, and achieving a vibration reduction effect.

[0066] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
