Description

Technical Field

[0001] This utility model relates to the field of chain technology, and in particular to a high-strength chain. Background Technology

[0002] Chains are a versatile mechanical product widely used in transmission, conveying, and some special applications. A chain typically consists of multiple links connected sequentially. Each link comprises an outer link plate, an inner link plate, a pin, a roller, and a bushing. The outer and inner link plates are connected by a pin, and the bushing is positioned outside the pin, while the roller is positioned outside the bushing to achieve the transmission function.

[0003] During transmission, existing chains often encounter harsh working environments with significant vibrations or sudden pulling forces. Due to the limited strength of traditional chains, large tensile forces are generated between chain links under such working conditions, causing local deformation at the connection points between the outer and inner chain plates and the pins. Over time, this can easily lead to fatigue of the outer and inner chain plates, or even breakage, affecting the normal operation of the chain. Utility Model Content

[0004] This utility model discloses a high-strength chain, which mainly solves the problem that traditional chains have low strength and are prone to breakage of the outer and inner chain plates in harsh working environments.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides a high-strength chain, including multiple chain links that are rotatably connected to each other. Each chain link includes symmetrically arranged chain plates. The two ends of two chain plates are connected by a pivot pin. A roller is provided on the pivot pin so that the roller is positioned between the two chain plates.

[0007] The chain plate includes a first plate and a second plate, with a bending plate connecting the first plate and the second plate, creating a gap on the same side of the first plate and the second plate. The connection between the bending plate and the first plate and the second plate is flexible. A first chain hole is passed through the first plate, and a second chain hole is passed through the second plate. A first reinforcing ring is provided on one side of the first plate along the outer periphery of the first chain hole, and a second reinforcing ring is provided on one side of the second plate along the outer periphery of the second chain hole.

[0008] In one embodiment, the first reinforcing ring is disposed on the side of the chain plate facing the roller, and the second reinforcing ring is disposed on the side of the chain plate away from the roller.

[0009] In one embodiment, a buffer is symmetrically connected between each two adjacent links, and the two ends of the buffer are rotatably connected to the corresponding pins. The buffer includes a first connecting plate and a second connecting plate, and an elastic plate is connected between the first connecting plate and the second connecting plate.

[0010] In one embodiment, the cross-section of the elastic plate has a wave-shaped structure.

[0011] In one embodiment, the elasticity of the elastic plate is greater than that of the bending plate.

[0012] In one embodiment, the first connecting plate has a first through hole, and the second connecting plate has a second through hole, both of which are adapted to the shaft pin.

[0013] The advantages or beneficial effects of the above technical solution include at least the following: with the cooperation of the first plate, the second plate, and the bending plate of the chain plate, when the bending plate connects the first plate and the second plate, there can be a gap between the same surface of the first plate and the second plate, that is, the spacing between the first plates of adjacent chain plates is different from the spacing between the second plates, thereby strengthening the chain plate and allowing the chain plate to have room to extend when subjected to rapid pulling, thus providing strength to the chain plate. At the same time, the first reinforcing ring and the second reinforcing ring are set at the positions of the first chain hole and the second chain hole of the first plate and the second plate, which can increase the contact area of ​​the first chain hole and the second chain hole, thereby reducing the local stress when the chain links are pulled, thereby improving the strength of the two ends of the chain plate and enhancing the overall strength of the chain.

[0027] It should be noted that the terms "a" and "a plurality of" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0028] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0029] See Figure 1 and Figure 2This utility model provides a high-strength chain, including multiple chain links 1 that are rotatably connected to each other. Each chain link 1 includes symmetrically arranged chain plates 11. The two ends of two chain plates 11 are connected by axle pins 12. Rollers 13 are provided on the axle pins 12, so that the rollers 13 are positioned between the two chain plates 11. A sleeve (not shown in the figure) can be fitted between the axle pins 12 and the rollers 13 to reduce the resistance between the axle pins 12 and the rollers 13.

[0030] The chain plate 11 includes a first plate 111 and a second plate 112. A bending plate 113 is connected between the first plate 111 and the second plate 112, so that the same side of the first plate 111 and the second plate 112 are spaced apart. The connection between the bending plate 113 and the first plate 111 and the second plate 112 is flexible. A first chain hole 114 is passed through the first plate 111, and a second chain hole 115 is passed through the second plate 112. A first reinforcing ring 116 is provided on one side of the first plate 111 along the outer periphery of the first chain hole 114, and a second reinforcing ring 117 is provided on one side of the second plate 112 along the outer periphery of the second chain hole 115.

[0031] With the above structure, the first plate 111, the second plate 112, and the bending plate 113 of the chain plate 11 cooperate to connect the first plate 111 and the second plate 112. This allows for a gap between the same surface of the first plate 111 and the second plate 112, meaning that the spacing between adjacent chain plates 11 corresponding to the first plate 111 is different from the spacing between the second plate 112. This strengthens the chain plate 11 and provides it with room to extend when subjected to rapid tension, thus enhancing its strength. Furthermore, the placement of the first reinforcing ring 116 and the second reinforcing ring 117 at positions corresponding to the first chain holes 114 and 115 on the first plate 111 and the second plate 112 increases the contact area between the first chain holes 114 and 115, thereby reducing local stress during tension between chain links 1 and improving the strength at both ends of the chain plate 11, thus enhancing the overall strength of the chain.

[0032] In one embodiment, see Figure 2 and Figure 3 The first reinforcing ring 116 is disposed on the side of the chain plate 11 facing the roller 13, and the second reinforcing ring 117 is disposed on the side of the chain plate 11 away from the roller 13. In practical applications, by setting the orientation of the first reinforcing ring 116 and the second reinforcing ring 117, it is possible to prevent the first reinforcing ring 116 and the second reinforcing ring 117 of adjacent chain links 1 from interfering with each other when the chain links 1 are connected.

[0033] In one embodiment, see Figure 1 and Figure 4Each pair of adjacent chain links 1 is symmetrically connected with a buffer element 2. The two ends of the buffer element 2 are rotatably connected to the corresponding pins 12. The buffer element 2 includes a first connecting plate 21 and a second connecting plate 22, and an elastic plate 23 is connected between the first connecting plate 21 and the second connecting plate 22. The adjacent buffer elements 2 are staggered. In practical application, the cooperation of the first connecting plate 21 and the second connecting plate 22 of the buffer element 2 enables the elastic plate 23 to be connected between two adjacent chain links 1. When a slight deformation occurs between two adjacent chain links 1, the elastic force of the elastic plate 23 can buffer the deformation, thereby protecting the chain plate 11 and improving its service life.

[0034] The cross-section of the elastic plate 23 is a wavy structure. In practical applications, setting the cross-section of the elastic plate 23 to a wavy structure enables the elastic plate 23 to have better elasticity.

[0035] The elasticity of the elastic plate 23 is greater than that of the bending plate 113. In practical applications, by setting the elasticity of the elastic plate 23 to be greater than that of the bending plate 113, the elastic plate 23 can buffer the tensile force it bears in advance.

[0036] A first through hole 211 is provided on the first connecting plate 21, and a second through hole 221 is provided on the second connecting plate 22. Both the first through hole 211 and the second through hole 221 are adapted to the shaft pin 12. In practical applications, the buffer 2 can be stably connected to the shaft pin 12 through the cooperation of the first through hole 211 and the second through hole 221.
