Description

Technical Field

[0001] The utility model relates to the technical field of V-belts, and in particular to a high-friction V-belt. Background Art

[0002] V-belt, also known as rubber triangle belt, generally refers to mechanical parts commonly used to transmit power.

[0003] However, it was found during use that if the output power of the rotating shaft or transmission wheel used to drive the V-belt increases, the tension transmitted to the V-belt will also increase, which will cause the V-belt to be subjected to greater tension, thereby causing the V-belt to stretch. When the V-belt stretches, its tension and tension will decrease, resulting in a weakening of the close contact between the V-belt and the rotating shaft or transmission wheel, thereby resulting in insufficient friction effect, making the V-belt prone to deformation, affecting the transmission efficiency of the V-belt, and even causing the V-belt to be unusable. Utility Model Content

[0004] The utility model provides a high-friction V-belt, which solves the problem in the related art that the V-belt has insufficient friction after being stretched under force.

[0005] The technical solution of the utility model is as follows:

[0006] A high-friction V-belt comprises a belt body, wherein the belt body comprises a main belt body and a plurality of sub-belt bodies, wherein the main belt body is fixedly connected to the sub-belt bodies, the sub-belt bodies are arranged in sequence along a linear direction, and each sub-belt body is provided with an anti-slip structure, wherein the anti-slip structure comprises a plurality of anti-slip teeth;

[0007] The anti-slip teeth are sequentially arranged along a linear direction, and the arrangement direction of the belt-dividing bodies is perpendicular to the arrangement direction of the anti-slip teeth.

[0008] Furthermore, each of the belt-dividing bodies is made of elastic material, and each of the anti-slip teeth on each of the belt-dividing bodies is integrally formed with the belt-dividing body.

[0009] Furthermore, each of the strip bodies is a hollow structure, and a plurality of tensile cores are provided inside the strip body, and the tensile cores are arranged in sequence along a linear direction.

[0010] Furthermore, a filling body is provided between each tensile core and the strip body, and between adjacent tensile cores, and the filling body is made of some elastic material.

[0011] Furthermore, each of the tensile cores is located at an end of the sub-belt body away from the main belt body.

[0012] Furthermore, the main belt body includes an anti-fracture portion and an anti-stretch portion, the anti-stretch portion is located between the anti-fracture portion and each sub-belt body, the anti-fracture portion includes a buffer layer and a plurality of tensile ropes, and the anti-stretch portion is composed of a plurality of glass fiber woven layers.

[0013] Furthermore, each of the anti-tension ropes is located in a buffer layer, and the buffer layer is provided with a plurality of mounting holes for each of the anti-tension ropes to pass through.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] 1. The belt body in the present invention includes a main belt body and a plurality of sub-belt bodies. The presence of each sub-belt body reduces the force-bearing area of ​​the present invention acting on the drive wheel or the drive shaft, thereby increasing the force acting on the drive wheel or the drive shaft. As the force increases, the friction between the present invention and the drive wheel or the drive shaft also increases.

[0016] 2. In the present invention, each sub-belt is provided with an anti-skid structure, and each anti-skid structure includes a plurality of anti-skid teeth. That is, with the presence of the anti-skid teeth, the contact between the sub-belt and the drive wheel or drive shaft is changed, so that more surface area between the two is involved in friction, thereby increasing the friction between the two by increasing the effective contact area between the two.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 and 2 As shown, the present embodiment provides a high-friction V-belt, which mainly includes a belt body 1. The belt body 1 includes a main belt body 11 and a plurality of sub-belt bodies 12. The main belt body 11 is fixedly connected to the sub-belt bodies 12. The sub-belt bodies 12 are arranged in sequence along a linear direction. That is, the presence of the sub-belt bodies 12 causes a plurality of protrusions to appear on the originally relatively flat surface of the main belt body 11. The presence of these sub-belt bodies 12 (protrusions) reduces the contact area between the main belt body 1 and the transmission wheel or transmission shaft. Prior to this, in order to enable the present embodiment to cooperate with the transmission system for transmission, a tensioning force is usually generated in the present embodiment through a tensioning device. When the present embodiment is subjected to the tensioning force, a reaction force is generated in response thereto. Under the action of this reaction force, the present embodiment comes into close contact with the transmission wheel or transmission shaft. When the contact area decreases, the force acting on the transmission wheel or transmission shaft increases accordingly, and the friction between the present embodiment and the transmission shaft or rotating wheel increases, thereby fully ensuring the transmission efficiency of the present embodiment.

[0026] Furthermore, each sub-belt body 12 is provided with an anti-skid structure 2, which includes a plurality of anti-skid teeth 21. The anti-skid teeth 21 change the contact between each sub-belt body 12 and the transmission shaft or transmission wheel, so that more surface between the present embodiment and the transmission wheel or transmission shaft participates in the friction between the two, thereby increasing the effective contact area, thereby preventing the present embodiment from slipping during the transmission process, and ensuring the stability and reliability of the transmission structure; at the same time, due to the increase in the additional contact area, the present embodiment can more evenly distribute the friction and torque, thereby reducing the possibility of local stress concentration.

[0027] Each sub-belt body 12 is made of an elastic material, so that when each sub-belt body 12 contacts the surface of the transmission wheel or the transmission shaft under force, it will deform, so that the contact area between this embodiment and the transmission wheel or the transmission shaft is further expanded, and the friction between the two is also improved. In addition, the anti-skid teeth 21 on each sub-belt body 12 are integrally formed with itself, that is, each sub-belt body 12 is integrally formed with its corresponding anti-skid structure 2. While fully ensuring the stability of the connection between the two, the anti-skid teeth 21 are also made of an elastic material and will also deform under the action of force, thereby squeezing the surface of the transmission wheel or the transmission shaft, increasing the contact area between the anti-skid teeth 21 and its contact surface, and thus increasing the friction between the two.

[0028] The anti-skid teeth 21 are arranged in a linear direction, and the arrangement direction of the sub-belts 12 is perpendicular to the arrangement direction of the anti-skid teeth 21. This makes the directions of the friction forces borne by the sub-belts 12 and the anti-skid teeth 21 perpendicular and staggered to each other. This provides bidirectional friction in this embodiment. The friction forces in two directions can more evenly distribute the load and torque, thereby improving the stability of the transmission device.

[0029] like Figures 3 and 4 As shown, each of the strip bodies 12 in this embodiment has a hollow structure. A tensile core 121 is provided inside the strip body 12. When the strip body 12 is stretched under load, the tensile core 121 can disperse the stress to a larger area, reducing local stress concentration, thereby improving the load-bearing capacity and tensile strength of the overall structure of the strip body 12. There are a plurality of tensile cores 121, which are arranged in sequence along a linear direction. Through the cooperation of the tensile cores 121, they can simultaneously withstand tensile forces, better adapt to complex load conditions, ensure the tensile performance of the strip body 12, and improve the stability of the overall structure of the strip body 12.

[0030] The tensile core 121 in this embodiment is preferably made of polyester fiber thread. The polyester fiber thread has good elasticity and is not easily deformed, which fully ensures the tensile effect of the tensile core 121.

[0031] A filling body 122 is provided between each tensile core 121 and the strip body 12, and between adjacent tensile cores 121. The filling body 122 is made of elastic material. When the strip body 12 is stretched and deformed by force, the tensile core 121 transfers the external stress to the filling body 122, and the elastic material constituting the filling body 122 will deform. When the external stress disappears or is removed, the filling body 122 will return to its original shape. This ability enables the filling body 122 to have multiple functions such as shock absorption, buffering and impact energy absorption, thereby reducing the impact of external stress on the strip body 12.

[0032] The elastic materials in this embodiment are preferably wear-resistant elastic materials such as polyurethane, which fully ensures the service life of this embodiment.

[0033] Each tensile core 121 is located at the end of the sub-belt body 12 away from the main belt body 11, that is, each tensile core 121 is located at the inner ring of the sub-belt body 12. Because the inner ring of the sub-belt body 12 is subjected to greater stress during transmission, when each tensile core 121 is designed at the inner ring of the sub-belt body 12, the stress at the inner ring of the sub-belt body 12 can be directly dispersed, thereby ensuring the effectiveness of the tensile core 121.

[0034] The main belt body 11 includes an anti-fracture portion 111 and an anti-stretch portion 112. The anti-stretch portion 112 is located between the anti-fracture portion 111 and each sub-belt body 12. That is, the anti-stretch portion 112 on the main belt body 11 is located at the end of the main belt body 11 away from the sub-belt body 12. The anti-stretch portion 112 and each anti-stretch core 121 in this embodiment are respectively located at the two ends of this embodiment, which can better balance the internal stress of this embodiment and fully ensure the stability of the overall structure of this embodiment.

[0035] The anti-fracture part 111 includes a buffer layer 1111 and several tensile ropes 1112. The tensile rope 1112 in this embodiment is preferably a synthetic rope with a steel wire rope core, which combines the advantages of steel wire rope and synthetic rope, has certain softness and wear resistance, and excellent strength; the buffer layer 1111 is composed of elastic materials such as rubber, that is, each tensile rope 1112 is used to resist the force in the axial direction of the main belt body 11, and the buffer layer 1111 is used to absorb the force dispersed by the tensile rope 1112 and buffer the force in the radial direction of the main belt body 11. The two cooperate with each other to ultimately achieve the function of preventing the main belt body 11 from breaking, thereby ensuring the integrity of the overall structure of this embodiment.

[0036] The anti-stretching portion 112 is composed of several glass fiber woven layers. The glass fiber itself has a high elastic modulus. Even after being deformed under the action of external force, it can quickly return to its original shape and is not easily permanently deformed, thereby achieving an anti-stretching function and preventing this embodiment from being in a state of long-term elongation, resulting in tensile fatigue of this embodiment and affecting the service life of this embodiment.

[0037] Each tensile rope 1112 is located in the buffer layer 1111 , and the buffer layer 1111 is provided with a number of mounting holes 1113 for each tensile rope 1112 to pass through one by one, that is, each tensile rope 1112 is located in the buffer layer 1111 , which facilitates each tensile rope 1112 to disperse stress into the buffer layer 1111 .

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
