Description

Technical Field

[0001] This utility model relates to the field of synchronous belt technology, specifically a multi-layer composite material reinforced heavy-duty synchronous belt. Background Technology

[0002] Synchronous toothed belts, also known as timing belts, are similar to common belt drives such as V-belts and flat belts, and are a form of flexible transmission. Synchronous toothed belts use steel wire rope or fiberglass rope as the reinforcing layer, covered with polyurethane or neoprene rubber. The inner circumference of the belt is toothed to mesh with toothed pulleys. Because the reinforcing layer deforms little under load, it maintains a constant circumferential pitch, thus preventing relative slippage between the belt and pulleys and ensuring synchronous transmission with a constant transmission ratio.

[0003] However, existing synchronous belts are all single-layered in actual use. This can cause damage to the synchronous belt due to friction and other external factors during material conveying or movement, thus affecting the service life of the synchronous belt. To address this, we propose a multi-layer composite material reinforced heavy-duty synchronous belt. Utility Model Content

[0004] The purpose of this invention is to provide a multilayer composite material reinforced heavy-duty synchronous belt to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite material reinforced heavy-duty synchronous belt, comprising a synchronous belt body, the synchronous belt body comprising a polyurethane rubber belt layer, a steel wire rope layer and a neoprene rubber belt layer, the bottom of the polyurethane rubber belt layer being fixedly connected to the top of the steel wire rope layer, the bottom of the steel wire rope layer being fixedly connected to the bottom of the neoprene rubber belt layer, the polyurethane rubber belt layer comprising a first wear-resistant layer, a second wear-resistant layer and a third wear-resistant layer, the bottom of the first wear-resistant layer being fixedly connected to the top of the second wear-resistant layer, and the bottom of the second wear-resistant layer being fixedly connected to the top of the third wear-resistant layer.

[0006] Preferably, the inner side of the synchronous belt body is fixedly connected with belt teeth, and the belt teeth are rectangular.

[0007] Preferably, the toothed surface is engaged with a transmission tooth, and a transmission gear is fixedly connected to the inner side of the transmission tooth.

[0008] Preferably, the inner side of the toothed part is provided with a first groove, and the inner side of the transmission tooth is provided with a second groove.

[0009] Preferably, the top of the toothed part is provided with a first corrosion-resistant layer, and the top of the first corrosion-resistant layer is provided with a second corrosion-resistant layer.

[0010] Preferably, the first corrosion-resistant layer is made of a waterproof coating layer, and the second corrosion-resistant layer is made of a cement-based coating layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model utilizes a high-strength steel wire rope layer within the synchronous belt body. This high tensile strength allows it to withstand the large torque and tension during heavy equipment transmission, effectively preventing breakage or deformation of the synchronous belt during use and improving the reliability and stability of the transmission system. The polyurethane rubber belt layer comprises a first wear-resistant layer, a second wear-resistant layer, and a third wear-resistant layer. This multi-layered wear-resistant structure significantly enhances the wear resistance of the synchronous belt surface. During long-term transmission, it reduces frictional loss with transmission gears and other components, extending the service life of the synchronous belt and lowering equipment maintenance costs.

[0013] 2. This utility model forms a double protection through the first and second corrosion-resistant layers on the top of the belt teeth, which can effectively resist the erosion of water, oil, chemical media, etc., prevent the belt teeth from being damaged by corrosion, and ensure that the synchronous belt can still work normally in harsh environments with humid and corrosive substances. The rectangular belt teeth on the inner side of the synchronous belt precisely mesh with the transmission teeth of the transmission gear. The first groove on the inner side of the belt teeth and the second groove on the inner side of the transmission teeth cooperate with each other, enhancing the tightness and stability of the meshing, reducing slippage during the transmission process, realizing high-precision synchronous transmission, and ensuring the accuracy of equipment operation.

[0021] Please see Figures 1-4 The following technical solution is provided, specifically disclosing: a multi-layer composite material reinforced heavy-duty synchronous belt, including a synchronous belt body 1, the synchronous belt body 1 including a polyurethane rubber belt layer 11, a steel wire rope layer 12 and a neoprene rubber belt layer 13, the bottom of the polyurethane rubber belt layer 11 is fixedly connected to the top of the steel wire rope layer 12, the bottom of the steel wire rope layer 12 is fixedly connected to the bottom of the neoprene rubber belt layer 13, the polyurethane rubber belt layer 11 includes a first wear-resistant layer 111, a second wear-resistant layer 112 and a third wear-resistant layer 113, the bottom of the first wear-resistant layer 111 is fixedly connected to the top of the second wear-resistant layer 112, and the bottom of the second wear-resistant layer 112 is fixedly connected to the top of the third wear-resistant layer 113;

[0022] In practical use, the steel wire rope layer 12 in the synchronous belt body 1 is composed of high-strength steel wire rope, which has high tensile strength and can withstand the large torque and tension during the transmission of heavy equipment. This effectively prevents the synchronous belt from breaking or deforming during use, improving the reliability and stability of the transmission system. The polyurethane rubber belt layer 11 includes a first wear-resistant layer 111, a second wear-resistant layer 112, and a third wear-resistant layer 113. The multi-layered wear-resistant structure significantly enhances the wear resistance of the synchronous belt surface. During long-term transmission, it can reduce frictional loss with components such as the transmission gear 2, extend the service life of the synchronous belt, and reduce equipment maintenance costs. Example

[0023] Please see Figure 1 and Figure 2The following technical solution is provided, specifically disclosed: a belt tooth 4 is fixedly connected to the inner side of the synchronous belt body 1. The belt tooth 4 is rectangular. A transmission tooth 3 is meshed with the surface of the belt tooth 4. A transmission gear 2 is fixedly connected to the inner side of the transmission tooth 3. A first groove 5 is provided on the inner side of the belt tooth 4. A second groove 6 is provided on the inner side of the transmission tooth 3. A first corrosion-resistant layer 7 is provided on the top of the belt tooth 4. A second corrosion-resistant layer 8 is provided on the top of the first corrosion-resistant layer 7. The material of the first corrosion-resistant layer 7 is a waterproof coating layer. The material of the second corrosion-resistant layer 8 is a cement-based coating layer.

[0024] In actual use, the first corrosion-resistant layer 7 and the second corrosion-resistant layer 8 on the top of the belt teeth 4 form a double protection, which can effectively resist the erosion of water, oil, chemical media, etc., prevent the belt teeth from being damaged by corrosion, and ensure that the synchronous belt can still work normally in harsh environments with humid and corrosive substances. The rectangular belt teeth 4 on the inner side of the synchronous belt mesh precisely with the transmission teeth 3 of the transmission gear 2. The first groove 5 on the inner side of the belt teeth 4 and the second groove 6 on the inner side of the transmission teeth 3 cooperate with each other, which enhances the tightness and stability of the meshing, reduces the slippage phenomenon in the transmission process, realizes high-precision synchronous transmission, and ensures the accuracy of equipment operation.

[0025] In use: When the synchronous belt body 1 is subjected to tension during transmission, the steel wire rope layer 12, as the main load-bearing structure, uses the high strength characteristics of the steel wire rope to disperse and bear the tension, preventing the synchronous belt from being stretched, deformed or broken due to excessive force, providing reliable strength support for the synchronous belt, and ensuring the normal operation of the transmission system. During the meshing transmission process between the synchronous belt and the transmission gear 2, the multi-layer wear-resistant structure of the polyurethane rubber belt layer 11 continuously rubs against the surface of the transmission gear 3. The first wear-resistant layer 111, the second wear-resistant layer 112, and the third wear-resistant layer 113, with their respective wear-resistant properties, resist frictional loss in sequence. Through the gradual wear and consumption of the multi-layer structure, the wear life of the entire synchronous belt is extended, ensuring good transmission performance during long-term use. When the synchronous belt is in a humid or corrosive environment, the waterproof coating layer of the first corrosion-resistant layer 7 firstly plays the role of waterproofing and isolating mild corrosive media, preventing moisture and some corrosive substances from penetrating into the interior of the belt teeth 4. If a small amount of corrosive media penetrates the first corrosion-resistant layer 7, the cement-based coating layer of the second corrosion-resistant layer 8 further plays the role of corrosion resistance, blocking the penetration of corrosive media, thereby protecting the internal structure of the belt teeth 4 and the synchronous belt body 1, maintaining the stable performance of the synchronous belt. When the synchronous belt is working, the belt teeth 4 mesh with the transmission teeth 3 of the transmission gear 2. The rectangular teeth 4 fit tightly against the transmission teeth 3, and the first groove 5 and the second groove 6 interlock, increasing the friction and contact area during meshing. This ensures accurate power transmission between the synchronous belt and the transmission gear 2, preventing slippage or transmission errors and achieving precise synchronous transmission. This guarantees coordinated operation between all components of the equipment. The elasticity of the polyurethane rubber belt layer 11 allows the synchronous belt to buffer vibrations and absorb impacts during transmission, reducing transmission noise. The aging resistance of the neoprene rubber belt layer 13 ensures that the synchronous belt is not prone to hardening or cracking during long-term use. The high strength of the steel wire rope layer 12 provides reliable support at all times. The materials of each layer work together synergistically, giving the synchronous belt excellent comprehensive performance in terms of strength, wear resistance, and weather resistance, meeting the high requirements of heavy equipment for transmission components.
