Description

Technical Field

[0001] The utility model relates to the technical field of synchronous belts, in particular to a wear-resistant polyurethane synchronous belt. Background Art

[0002] The synchronous belt is an endless belt made of materials such as polyurethane or neoprene. Its inner circumference is made into a tooth shape, which meshes with the toothed pulley to achieve transmission. The working principle of the synchronous belt is based on the precise meshing of the belt teeth and the tooth grooves of the pulley. The tooth shape on the belt body matches the tooth grooves of the pulley. Through the close combination of the teeth, non-slip synchronous transmission is achieved.

[0003] According to the patent application number published on the China Patent Network, it is 202120612143.3, and the patent name is: Waterproof synchronous belt, including a synchronous belt body and a plurality of synchronous belt teeth equidistantly arranged on the lower surface of the synchronous belt body, the outer walls of the front and rear sides of the synchronous belt body are each provided with a plurality of V-shaped positioning grooves, the adjacent V-shaped positioning grooves on the front and rear sides are symmetrically arranged with respect to the synchronous belt body, and the plurality of V-shaped positioning grooves on the same side are equidistantly arranged along the length direction of the synchronous belt body. The utility model facilitates cutting the length of the synchronous belt body as needed along the direction of each V-shaped positioning groove through the mutual cooperation between the synchronous belt body, the V-shaped positioning grooves, the mounting grooves and the pins, and after cutting, the two ends are always concave and convex sections, avoiding the problem of mismatch of belt teeth at the connection and reducing waste. At the same time, when connecting, multiple pins are first used for fixing, and then polymer solvent glue is encapsulated at the connection, which can effectively reduce the problem of fracture at the connection, thereby avoiding the impact of fracture on transmission efficiency.

[0004] However, the structure of existing synchronous belts is relatively simple, and they are mainly made of injection molding materials such as polyurethane or neoprene. Since synchronous belts made of polyurethane or neoprene are elastic and will suffer losses due to friction, certain errors will be generated during the transmission process, resulting in inaccurate transmission ratios, which may become a problem in applications with extremely high precision requirements.

[0005] Therefore, it is necessary to redesign the wear-resistant polyurethane synchronous belt. Utility Model Content

Since the synchronous belt made of polyurethane or chloroprene rubber is elastic, certain errors will be generated during the transmission process, resulting in inaccurate transmission ratio, which may become an interference problem in applications with extremely high precision requirements.

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.

[0027] like Figures 1 to 4 As shown, the utility model provides a wear-resistant polyurethane synchronous belt, including a belt body 1;

[0028] A concave-convex toothed belt 2 is provided at the bottom of the belt body 1, a support structure 3 is provided on the top of the bag body, a heat dissipation structure 4 is provided inside the support structure 3, a protective layer 5 is provided on the top of the support structure 3, and a wear-resistant layer 6 is provided at the bottom of the concave-convex toothed belt 2.

[0029] refer to Figure 3 The left and right sides of the belt body 1 are fixedly connected with reinforcing ribs 7, the material of the reinforcing ribs 7 is a flexible metal material, and the bottom of the reinforcing ribs 7 is fixedly connected to the top of the concave-convex toothed belt 2.

[0030] As a technical optimization solution of the present invention, the reinforcement ribs 7 fixedly connected on the left and right sides of the belt body 1 effectively enhance the overall strength and rigidity of the belt body 1, improving the belt body's resistance to tearing and fatigue during transmission. The use of flexible metal materials ensures that the reinforcement ribs 7 maintain strength while also having a certain degree of flexibility, which can better adapt to the deformation and bending of the belt body 1.

[0031] refer to Figure 3 The heat dissipation structure 4 includes a heat conducting plate 8 embedded in the top of the concave-convex toothed belt 2. The heat conducting plate 8 is located on the inner side of the reinforcing rib 7. The material of the heat conducting plate 8 is heat conducting rubber. The heat conducting plate 8 and the concave-convex toothed belt 2 are adhered to each other by hot melting. The top end of the heat conducting plate 8 passes through the belt body 1 and extends to the top of the belt body 1.

[0032] As a technical optimization solution of the present invention, through the design of the heat dissipation structure 4, the heat generated by the belt body 1 during the transmission process is promptly conducted away through the heat conduction plate 8 embedded in the top of the concave-convex toothed belt 2, thereby avoiding performance degradation or damage caused by overheating.

[0033] refer to Figure 3 A temperature control layer 9 is fixedly connected to the top of the belt body 1. The material of the temperature control layer 9 is heat-conducting rubber. The temperature control layer 9 is wrapped around the surface of the heat-conducting plate 8 and is hot-melt connected to the heat-conducting plate 8.

[0034] As a technical optimization solution of the present invention, the heat dissipation capacity of the belt body 1 is further enhanced by the provision of the temperature control layer 9. By wrapping the surface of the heat conducting plate 8 and being hot-melt connected to the heat conducting plate 8, the temperature control layer 9 can more effectively absorb and disperse the heat generated by the belt body 1, ensuring that the belt body 1 always operates within an appropriate temperature range.

[0035] refer to Figure 3 The protective layer 5 includes a waterproof coating 10 fixedly connected to the top of the temperature control layer 9. The waterproof coating 10 is formed by applying and drying a waterproof coating. A PVC film 11 is adhered to the top of the waterproof coating 10. Both sides of the PVC film 11 extend to the outside of the belt body 1 and are fixedly connected to the belt body 1.

[0036] As a technical optimization solution of the present invention, the design of the protective layer 5 provides additional protection for the belt body 1. The waterproof coating 10 can block the intrusion of water and moisture, preventing the belt body 1 from aging or damage due to moisture. The adhesion and fixed connection of the PVC film 11 not only enhances the strength and durability of the protective layer 5, but also enables the protective layer 5 to better fit the surface of the belt body 1, forming an effective protective barrier.

[0037] refer to Figure 3 The wear-resistant layer 6 includes a chloroprene rubber layer 12 attached to the bottom of the concave-convex toothed belt 2, and a polyurethane layer 13 is fixedly connected to the bottom of the chloroprene rubber layer 12.

[0038] As a technical optimization solution of the present invention, through the design of the wear-resistant layer 6, the chloroprene rubber layer 12 and the polyurethane layer 13 attached to the bottom of the concave-convex toothed belt 2 significantly improve the wear resistance and durability of the belt body 1. The chloroprene rubber layer 12 has excellent wear resistance and tear resistance, and can resist friction and wear during transmission. The fixed connection of the polyurethane layer 13 further enhances the overall strength and elasticity of the wear-resistant layer 6, so that the belt body 1 can still maintain good performance during long-term, high-load transmission.

[0039] The working principle and use process of the utility model are as follows: First, a concave-convex toothed belt 2 is provided at the bottom of the belt body 1, which not only enhances the meshing degree between the belt body 1 and the pulley and improves the accuracy of the transmission, but also increases the contact area through the concave-convex structure of the tooth shape, which helps to disperse the pressure and reduce wear. At the same time, a wear-resistant layer 6 is specially provided at the bottom of the concave-convex toothed belt 2. The wear-resistant layer 6 is composed of a chloroprene rubber layer 12 and a polyurethane layer 13. The chloroprene rubber layer 12 has excellent wear resistance and tear resistance, while the polyurethane layer 13 further enhances the overall elasticity and durability. The combination of the two makes the synchronous belt more durable under long-term and high-load conditions. During the transmission process, it can still maintain good performance. Inside the belt body 1, the left and right sides are fixedly connected with reinforcing ribs 7. The reinforcing ribs 7 are made of flexible metal material, which not only enhances the overall strength of the belt body 1, but also ensures the stability of the belt body 1 during the transmission process through the fixed connection with the concave and convex toothed belt 2 at the bottom. At the same time, the inner side of the reinforcing rib 7 is inlaid with heat conducting plates 8. These heat conducting plates 8 are made of heat conducting rubber and are adhered to the concave and convex toothed belt 2 by hot melting. The design of the heat conducting plates 8 enables the heat generated by the belt body 1 during the transmission process to be conducted away in time, thereby avoiding performance degradation or damage due to overheating.

[0040] To sum up: this wear-resistant polyurethane synchronous belt enhances the meshing degree between the belt body 1 and the pulley by arranging the concave-convex toothed belt 2 at the bottom of the belt body 1, thereby improving the accuracy and stability of the transmission. At the same time, the design of the support structure 3, the heat dissipation structure 4 and the protective layer 5 respectively enhances the support, heat dissipation capacity and protective performance of the belt body 1, so that the synchronous belt can adapt to a wider range of working environments and conditions.
