Description

Technical Field

[0001] This utility model relates to the field of mobile phone case testing equipment technology, and in particular to a tensile-resistant triangular belt. Background Technology

[0002] Rubber transmission belts are important components in modern industrial production equipment. There are two basic types of transmission methods for transmission belts: friction transmission and meshing transmission. Friction transmission relies on the friction between the belt and the pulley to transmit motion and power. Friction transmission can be further divided into flat belt transmission, V-belt transmission, and multi-ribbed belt transmission, depending on the cross-sectional shape of the belt.

[0003] Currently, V-belts come in two types: special core structure and rope core structure. Each type consists of four parts: fabric covering, top rubber, tensile strength, and bottom rubber. Rope core structure V-belts are easy to manufacture, have moderate tensile strength, are inexpensive, and are widely used. Special core structure V-belts have good toughness and high strength, making them suitable for high-speed applications.

[0004] However, in high-strength and high-load applications, the existing design of V-belts is prone to breakage and has a short service life. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tensile-resistant V-belt to solve the technical problem that the existing V-belt design is prone to breakage and has a short service life in high-strength and high-load application scenarios.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A tensile-resistant triangular belt includes a base layer and an outer sheath. The base layer has an internal tensile-resistant structure and a reinforcing structure. The tensile-resistant structure includes an aramid braided core, a steel wire rope, a corrugated ring, and a polyester fiber core. The aramid braided core, steel wire rope, corrugated ring, and polyester fiber core are all disposed inside the base layer. The steel wire rope is located at the center of the corrugated ring, the aramid braided core is located on the outer convex inner side of the corrugated ring, and the polyester fiber core is located on the inner concave inner side of the corrugated ring. The reinforcing structure is located on top of the base layer.

[0008] Furthermore, the outer surface of the base layer is provided with a reinforcing layer and a heat insulation layer, and the inner walls of both the reinforcing layer and the heat insulation layer are provided with trapezoidal blocks, which are fitted and installed with the base layer.

[0009] Furthermore, the reinforcing layer and the heat insulation layer are in contact, and the outer layer is wrapped around the outside of the base layer.

[0010] Furthermore, the reinforcing structure includes a cross-fiber layer and reinforcing ribs, wherein the cross-fiber layer is disposed inside the top side of the base layer, and the reinforcing ribs are located inside the cross grooves of the cross-fiber layer.

[0011] The beneficial effects of this utility model are:

[0012] With its reinforced structure, the aramid braided core provides excellent tensile strength due to its high strength and high temperature resistance. The steel wire rope further enhances the load-bearing capacity of the belt, especially under high load conditions. The corrugated ring design not only increases the flexibility of the V-belt but also improves its abrasion resistance during bending. The polyester fiber core, with its good abrasion resistance and aging resistance, further enhances the overall abrasion resistance and lifespan of the V-belt. The reinforced structure, located at the top of the base layer, provides additional strength support, ensuring overall structural stability. When the V-belt is running in mechanical transmission, the aramid braided core and steel wire rope share the tension. The corrugated ring and polyester fiber core enhance the overall tensile strength and abrasion resistance, while the reinforced structure ensures the structural integrity and stability of the V-belt under heavy loads, thereby effectively improving the tensile strength and service life of the V-belt.

[0021] Please see Figure 1-2 As shown, a tensile triangular belt includes: a base layer 11 and an outer layer 1, wherein the base layer 11 is provided with a tensile structure and a reinforcing structure.

[0022] The tensile structure includes an aramid braided core 4, a steel wire rope, a corrugated ring 6, and a polyester fiber core 10. The aramid braided core 4, the steel wire rope, the corrugated ring 6, and the polyester fiber core 10 are all located inside the base layer 11. The steel wire rope is located at the center of the corrugated ring 6, the aramid braided core 4 is located on the outer convex inner side of the corrugated ring 6, and the polyester fiber core 10 is located on the inner concave inner side of the corrugated ring 6. The reinforcing structure is located on the top of the base layer 11.

[0023] Specifically, through the inclusion of a reinforcing structure, the aramid braided core 4, with its high strength and high temperature resistance, provides excellent tensile strength. The steel wire rope further enhances the load-bearing capacity of the belt, especially under high load conditions. The design of the corrugated ring 6 not only increases the flexibility of the V-belt but also improves its wear resistance during bending. The polyester fiber core 10, with its good wear resistance and aging resistance, further enhances the overall wear resistance and lifespan of the V-belt. The reinforcing structure, located at the top of the base layer 11, provides additional strength support, ensuring the overall structural stability. When the V-belt operates in mechanical transmission, the aramid braided core 4 and the steel wire rope share the tensile force. The corrugated ring 6 and the polyester fiber core 10 enhance the overall tensile strength and wear resistance, while the reinforcing structure ensures the structural integrity and stability of the V-belt under heavy loads, thereby effectively improving the tensile strength and service life of the V-belt. The corrugated ring 6 is made of short fiber rubber.

[0024] In this embodiment, the base layer 11 is wrapped with a reinforcing layer 2 and a heat insulation layer 3. The inner walls of the reinforcing layer 2 and the heat insulation layer 3 are provided with trapezoidal blocks 7, and the trapezoidal blocks 7 are fitted and installed with the base layer 11. The reinforcing layer 2 and the heat insulation layer 3 are in contact, and the outer wrapping layer 1 is wrapped around the outside of the base layer 11.

[0025] Specifically, the outer layer 1 is a fabric layer, which is composed of plain weave canvas cut at 45°, mainly cotton canvas and polyester-cotton canvas. It has excellent elasticity and friction, can connect various parts into a whole, protect other parts from wear and corrosion, and can increase the stiffness of the V-belt. The principle is based on existing technology. The base layer 11 is made of rubber, the reinforcing layer 2 is made of polyester fiber, and the heat insulation layer 3 is made of silicone rubber. It has excellent high temperature resistance and good oxidation stability, which can prevent the friction force of the V-belt during transmission from being transmitted to the inside of the V-belt and affecting its internal structure. Trapezoidal blocks 7 are used for fitting and installation, which facilitates its positioning and installation.

[0026] The reinforcing structure includes a cross-fiber layer 8 and a reinforcing rib 9. The cross-fiber layer 8 is disposed inside the top side of the base layer 11, and the reinforcing rib 9 is located inside the cross groove of the cross-fiber layer 8.

[0027] Specifically, since the top of the V-belt is subjected to greater stress during use, the cross-fiber layer 8 is set inside the top side of the base layer 11. The longitudinal fibers provide tensile strength, and the transverse fibers enhance transverse stability, effectively increasing the interlacing strength of the large area of ​​fibers and improving the overall load-bearing capacity of the belt. The reinforcing rib 9 is located inside the cross groove of the cross-fiber layer 8. By providing additional support and enhancing the transverse stability and torsional resistance of the belt, the cross-fiber layer 8 first provides multi-directional tensile strength, and then the reinforcing rib 9 further strengthens it, ensuring that the entire belt can evenly bear and transmit power under load conditions, thereby achieving excellent tensile performance and durability. The cross-fiber layer 8 is made of aramid fiber, and the reinforcing rib 9 can be made of steel wire rope or polyester fiber core 10.

[0028] In summary, compared with existing technologies, this V-belt has at least the following beneficial effects: With its reinforced structure, the aramid braided core 4 provides excellent tensile strength due to its high strength and high temperature resistance; the steel wire rope further enhances the load-bearing capacity of the belt, especially under high load conditions. The design of the corrugated ring 6 not only increases the flexibility of the V-belt but also improves its wear resistance during bending. The polyester fiber core 10, with its good wear resistance and aging resistance, further enhances the overall wear resistance and lifespan of the V-belt. The reinforced structure, located at the top of the base layer 11, provides additional strength support, ensuring overall structural stability. When the V-belt operates in mechanical transmission, the aramid braided core 4 and the steel wire rope jointly bear the tension. The corrugated ring 6 and the polyester fiber core 10 enhance the overall tensile strength and wear resistance, while the reinforced structure ensures the structural integrity and stability of the V-belt under heavy loads, thereby effectively improving the tensile performance and service life of the V-belt. The corrugated ring 6 is made of short-fiber rubber.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
