Description

Technical Field

[0001] This disclosure relates to the field of machinery, and more particularly to a washer, the use of the washer in the assembly of hexagonal bolts and nuts and the assembly of carriage bolts and nuts, a method for fastening V-clamps, and a method for manufacturing the washer for bolt-nut assemblies. Background Technology

[0002] Washers play a crucial role in the assembly of bolts and nuts. They primarily enhance the overall stability and functionality of the connection by serving several purposes.

[0003] Load distribution: When nuts and bolts are tightened, the washer, as a flat, smooth surface, distributes the load applied by the nut over a larger area. This helps reduce stress on the materials used in the connection, avoiding localized stress concentrations and potential damage.

[0004] Protective function: Washers protect the materials used in the connection. They provide a barrier between the nut and the connecting surfaces, preventing damage from direct contact and reducing the risk of corrosion or wear over time.

[0005] Alignment: Placing the washer under the nut ensures that the bolt and nut are properly aligned during assembly.

[0006] Anti-slip and friction control: Some washers, such as spring washers, can grip mating surfaces, increasing frictional resistance and creating a stronger connection.

[0007] Spacers or dividers: In some cases, washers can be used as spacers or dividers to adjust the height or alignment of connection points. They help to fill any gaps or irregularities between bolts, nuts, and connecting surfaces, ensuring proper installation.

[0008] In summary, washers play a crucial role in the combination of bolts and nuts. They enhance the effectiveness and service life of the connection by distributing load, protecting the connecting surfaces, assisting alignment, controlling slippage and friction, and acting as spacers or dividers (if necessary), thus ensuring a safe and reliable connection.

[0042] The following descriptions of exemplary embodiments are with reference to the accompanying drawings. These exemplary embodiments are merely specific implementations of this disclosure and are not intended to limit the scope of this disclosure in any way. Directional terms used in this disclosure, such as [up], [down], [front], [back], [left], [right], [inner], [outer], [end], etc., refer only to directions referenced to the accompanying drawings. Therefore, the directional terms used are for illustration and understanding of this disclosure and not for limiting it. In the drawings, structurally similar units are denoted by the same reference numerals. In the drawings, for clarity and ease of description, the dimensions of some components have been exaggerated and / or the structures of some components simplified. That is, the dimensions and structures of each component shown in the drawings are schematic and are not intended to limit the scope of this disclosure.

[0043] Figure 1 The figure shows a schematic perspective view of a gasket according to an exemplary embodiment disclosed herein. Figure 1 As shown, washer 1 includes a base 2, which includes a through hole. By way of example and not limitation, base 2 is illustrated as annular. However, it is understood that base 2 may take any other suitable shape, and this disclosure does not impose any limitation thereon. As shown, a protrusion 20 extending from the inner wall of base 2 is provided at the through hole of base 2. By way of example and not limitation, four protrusions 20 are illustrated. That is, each protrusion 20 approximately corresponds to a quarter-circle. The protrusions 20 are used to fit into the threads of a bolt. In the example, washer 1 is made of plastic, for example, high-density polyethylene (HDPE).

[0044] Figure 1The gasket shown is suitable for pure gasoline-powered engines. In factory testing, the HDPE gasket completely disintegrates after the engine runs. However, to make the gasket suitable for all engines (e.g., hybrid engines), the inventors based... Figure 1 The gasket design shown has been improved. The improved gasket can at least solve the problem of insufficient decomposition of HDPE material during factory testing, which leads to the continued decomposition of HDPE material at the customer end and the generation of smoke.

[0045] Figure 2 The figure illustrates a schematic perspective view of another washer according to an exemplary embodiment disclosed herein. As shown, washer 1 includes a base 2 having a through hole 3 through which a bolt passes. Washer 1 also includes a plurality of legs 5 extending from the periphery 4 of the through hole 3 of the base 2 (e.g., extending toward the same side of the plane in which the base 2 is located). Each of the plurality of legs 5 has a first tapered segment 6 inclined toward the central axis (not shown) of the through hole 3. The central axis refers to a straight line passing through the geometric center of the base (or the through hole, especially assuming the base is centrally symmetric as a whole) and perpendicular to the plane in which the base is located (ignoring the thickness of the base). By way of example and not limitation, the base 2 is illustrated as annular. However, it is understood that the base 2 may take any other suitable shape, and this disclosure does not impose any limitation thereon. By way of example and not limitation, the number of legs 5 is illustrated as four. However, it is understood that the number of legs 5 may be varied as needed, and this disclosure does not impose any limitation thereon. As an example and not a limitation, as shown, for each leg 5, the first tapered section 6 may optionally be provided with a transition section; alternatively, a transition section may optionally be provided between the base 2 and the first tapered section 6. Accordingly, the term "at least partially extended range" in the former case may refer to the portion of the first tapered section 6 excluding the transition section or a sub-range of that portion (that portion having the end of the first tapered section 6 remote from the base 2), while in the latter case it may refer to at least a portion of the first tapered section 6 (that at least a portion having the end of the first tapered section 6 remote from the base 2). According to embodiments of the present disclosure, the first tapered section of each leg may be shaped to conform to the crest of the thread when elastically opened by the thread of a bolt passing through a through hole, for example in Figure 13 The center is indicated by two dotted circles.

[0046] Figure 3 The figure illustrates a schematic side view of another washer according to an exemplary embodiment disclosed herein. As shown, the first tapered segment 6 of each leg 5 is inclined toward the central axis of the through hole (not shown), which, for example, passes through the geometric center of the annular base and is perpendicular to the plane of the base (ignoring the thickness of the base)). It can be understood that due to view obstruction, Figure 3 Only the illustrations are shown. Figure 2Three of the legs 5 of the washer. Similarly, the number of legs 5 can be changed as needed, and this disclosure does not impose any limitation on this. Figures 2 to 3 In the illustrated washer design, the first tapered section is shaped to fit (e.g., tightly wrap) the thread crest when elastically spread by the thread of a bolt passing through a through hole, effectively preventing the bolt from falling off during transport (e.g., from a clamp (such as a V-clamp) employing a bolt-nut assembly). According to embodiments of this disclosure, such as... Figure 2 and Figure 3 As shown, the first tapered section 6 can be configured to extend straight within at least a portion of the extension range 11 at the end of the first tapered section 6 that is away from the base 2.

[0047] Figure 4 The figure shows a schematic perspective view of yet another washer according to the exemplary embodiments disclosed herein.

[0048] Figure 5 The figure shows a schematic side view of yet another washer according to the exemplary embodiments disclosed herein. Figures 4 to 5 and Figures 2 to 3 The difference is that, within at least a portion of the extension 11 of the first tapered section 6 at the end away from the base 2, the first tapered section 6 extends in a curved manner instead of in a straight line.

[0049] According to embodiments of this disclosure, such as Figure 4 and Figure 5 As shown, the first tapered section can be configured to extend curvedly within at least a partial extension range 11 of the end of the first tapered section 6 away from the base 2, and within at least a partial extension range 11, the closer the first tapered section 6 is to that end, the greater the inclination of the first tapered section 6 toward the central axis (not shown) of the through hole 3. Figures 2 to 3 In the washer design shown, the first tapered section is shaped to fit (e.g., tightly wrap) the crest of the thread when it is elastically spread by the thread of the bolt passing through the through hole, and the elastic force of the thread crest on the first tapered section is increased due to the first tapered section extending flexurally over at least a portion of its extension range, which effectively prevents the bolt from falling off during transport.

[0050] Figure 6 The figure shows a schematic perspective view of another washer according to the exemplary embodiments disclosed herein.

[0051] Figure 7 The figure shows a schematic side view of another washer according to the exemplary embodiments disclosed herein. Figures 6 to 7 and Figures 2 to 3 ,and Figures 4 to 5The difference is that, for each leg 5, there is a second tapered section 12 adjacent to the end of the first tapered section away from the base 2.

[0052] According to embodiments of this disclosure, such as Figure 6 and Figure 7 As shown, each of the plurality of legs 5 also has a second tapered section 12 adjacent to the end of the first tapered section 6 away from the base 2, the second tapered section 12 having a greater inclination toward the central axis (not shown) of the through hole 3 than the first tapered section 6.

[0053] refer to Figure 13 , Figure 13 The figure illustrates how a washer prevents a bolt from falling off a nut, according to an exemplary embodiment disclosed herein. Figure 13 The gaskets in the middle are adopted Figures 6 to 7 The washer design shown. (As shown) Figure 13 The single dashed circle indicates that, due to the fact that each leg of the washer has a second tapered section in addition to the first tapered section, at least one leg of the washer can interfere with the crest area of ​​the thread (e.g., resist the crest of the thread) in the event of bolt displacement due to loosening, thereby providing resistance in the opposite direction to the bolt displacement due to loosening, which helps to prevent the bolt from loosening further and falling off during transportation. It is understood that, when using... Figures 6 to 7 With the washer design shown, the displacement of the bolt due to loosening will not exceed one thread pitch.

[0054] Figure 8 The figure shows a schematic exploded view of a V-shaped clamp with a hexagonal bolt-nut assembly according to the exemplary embodiments disclosed herein. Figure 9 The figure shows a schematic partially exploded view of a V-shaped clamp with a hexagonal bolt-nut assembly according to the exemplary embodiments disclosed herein.

[0055] As an example, not a limitation, such as Figure 8 and Figure 9 As shown, the V-shaped clamp includes a pair of lugs 14 and 15. A nut 7 is riveted to one of the lugs 14. The nut 7 can be passed through by a mating bolt 8. The nut 7 may have a threaded section 16 and a non-threaded section 17, the non-threaded section 17 receiving the bolt 8 and adjacent to one end face 18 of the nut 7.

[0056] Figure 10 The figure shows a schematic diagram illustrating the initial state of the fastening process of a V-clamp with a hexagonal bolt-nut assembly according to the exemplary embodiments disclosed herein.

[0057] According to embodiments of this disclosure, a method for fastening a V-shaped clamp (e.g., a bolt-locking clamp) may include: step S11, passing a bolt 8 through a lug (e.g., lug 15 as shown); step S12, pushing a washer 1, as described above, from the end of the bolt 8 to be engaged with the nut 7 toward the inner wall of the lug 15 (note that the leg 5 of the washer 1 faces the nut 8); and step S13, tightening the bolt 8 to the nut 7. Exemplarily, in step S13, tightening the bolt 8 to the nut 7 may include tightening the bolt 8 to the nut 7 such that the leg 5 of the washer 1 at least partially extends into the unthreaded section 17 of the nut 7. Exemplarily, in step S13, tightening the bolt 8 to the nut 7 may include tightening the bolt 8 to the nut 7 such that the base 2 of the washer 1 approaches or contacts the end face 18 of the nut 7.

[0058] Understandable, although Figures 8 to 10 The bolt shown in the diagram is a hexagonal bolt, but any other suitable type of bolt and its matching nut can be selected as needed for fastening V-clamps, such as square bolts and nuts, etc.

[0059] Figure 11 The figure shows a schematic diagram of a hexagonal bolt-nut assembly to be tightened according to the exemplary embodiments disclosed herein. Figure 12 The figure illustrates a schematic diagram of a hexagonal bolt-nut assembly during tightening according to the exemplary embodiments disclosed herein. It can be understood that the base 2 of the washer 1 may prematurely contact the end face 18 of the nut 7 before the bolt is fully tightened.

[0060] Figure 14 The figure shows a schematic partial cross-sectional view of a V-shaped clamp with a carriage bolt-nut assembly according to an exemplary embodiment disclosed herein.

[0061] According to embodiments of this disclosure, a method for fastening a V-shaped clamp (e.g., a bolt anti-loosening clamp) may include: step S21, passing a carriage bolt through a lug 14 of a V-shaped clamp 13 such that the head 19 of the carriage bolt presses against the outer wall of the lug 14; step S22, pressing a washer 1, as described above, from the end of the carriage bolt to be engaged with a mating nut against the inner wall of the lug 14, such that the base 2 of the washer 1 contacts the inner wall; and step S23, tightening a nut from the end of the carriage bolt toward the head 19 of the carriage bolt from the other lug 15 of the V-shaped clamp 13.

[0062] According to embodiments of this disclosure, the angle between the second tapered region and the first tapered region can be between 150 degrees and 180 degrees. It should be noted that the range of this angle can be any suitable interval with a lower bound greater than or equal to 150 degrees and an upper bound less than or equal to 180 degrees; this disclosure does not impose any limitations in this regard.

[0063] According to embodiments of this disclosure, the number of legs can be two or more.

[0064] It should be noted that throughout the accompanying drawings of this application, although the legs of the washers are shown to be equally spaced from each other, this is not necessary.

[0065] According to embodiments of this disclosure, the gasket may be integrally molded.

[0066] According to embodiments of this disclosure, the material of the gasket can be selected from the group consisting of: high-temperature resistant polymers, stainless steel, metals, alloys, or combinations thereof. This solves the problem of insufficient decomposition of HDPE material during factory testing, followed by continued decomposition at the customer end, generating fumes. The term "tapering" has at least two meanings herein: first, if the first tapered sections of the plurality of legs of the base extend sufficiently (assuming each leg has only a first tapered section), the geometry formed by the legs resembles a cone (the more legs there are and the smaller the spacing between them, the more cone-like it is); second, if the first tapered sections of the plurality of legs of the base extend sufficiently, the geometry formed by the legs gradually tapers from the base in the extension direction.

[0067] The term "elastic" refers to the ability of a washer (especially the legs of the washer) to undergo elastic deformation without compromising its structure or function when subjected to force or load (e.g., the support force exerted by a bolt through a hole in the washer). For example, during bolt piercing or tightening, the displacement of the washer legs in a direction perpendicular to the bolt length or travel direction can occur between the crest and root of the bolt thread (e.g., similar to a lever).

[0068] The term "inclination" can refer to the degree of inclination or skewness of the tapered section of the leg relative to the central axis of the base through hole. Taking a first tapered section of the leg as an example, its inclination can refer to the "angle" formed by the first tapered section and the corresponding first tapered section extending from the base perpendicular to the plane of the base (ignoring the thickness of the base) (here the first tapered section can be regarded as a plane rather than a conical surface).

[0069] According to embodiments of this disclosure, a method for manufacturing a washer for bolt-nut assembly may include: step S31, providing a base having a through hole through which a bolt passes; step S32, providing a plurality of legs extending from the periphery of the through hole of the base, each of the plurality of legs having a first tapered section inclined toward the central axis of the through hole, the first tapered section of each of the legs being shaped to conform to the crest of the thread when elastically opened by the thread of the bolt passing through the through hole.
