Description

Technical Field

[0001] This utility model relates to the field of transmission component technology, specifically to a double-sided toothed belt for a high-horsepower harvester. Background Technology

[0002] Rubber V-belts, also known as triangular belts or V-belts, currently consist of three main parts in China: a rubber skeleton (i.e., the winding), a rubber base, and an outer fabric layer. However, in applications requiring high horsepower, traditional belts suffer from poor heat dissipation, high temperature rise, easy elongation, poor friction, low wear resistance, and easy deformation after speed changes. Therefore, based on the above problems, a transmission belt suitable for high-horsepower applications is needed. Utility Model Content

[0003] This invention proposes a double-sided toothed belt for high-horsepower harvesters, which solves the problem that traditional belts are unsuitable for use in high-horsepower scenarios.

[0004] The technical solution of this utility model is as follows:

[0005] A high-horsepower harvester double-sided toothed belt includes a pre-embedded skeleton and a transmission part. One side of the transmission part is provided with multiple transmission teeth, and the opposite side of the transmission teeth is provided with multiple structural teeth. The pre-embedded skeleton includes a tensile skeleton and a supporting heat-conducting skeleton. The tensile skeleton is pre-embedded in the transmission part along its length. The supporting heat-conducting skeleton has a U-shaped structure. One closed end of the supporting heat-conducting skeleton is set inside the transmission teeth, and the two sides of the open end of the supporting heat-conducting skeleton are respectively set inside two of the structural teeth.

[0006] The height of the transmission tooth profile is greater than the height of the structural tooth profile.

[0007] The cross-section of the transmission part along the width direction is trapezoidal.

[0008] The bottom of the gap between adjacent transmission teeth is arc-shaped.

[0009] The tensile skeleton is configured as multiple parallel skeletons located in the same horizontal plane.

[0010] The thermally conductive support frame includes multiple frames, and the thermally conductive support frame is disposed between two adjacent tensile frames.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] This utility model discloses a double-sided toothed belt for high-horsepower harvesters, applied in high-horsepower transmission scenarios. Its transmission section has a pre-embedded skeleton, and different toothed structures are set on both sides of the transmission section to adapt it for transmitting greater power in high-horsepower scenarios. Firstly, the pre-embedded skeleton in the transmission section is divided into a tensile skeleton and a supporting heat-conducting skeleton. The tensile skeleton is pre-embedded along the length of the transmission section, improving its tensile strength in the length direction and preventing elongation deformation caused by high-horsepower transmission. Furthermore, one side of the transmission section has transmission teeth, and the opposite side has structural teeth. The moving tooth profile meshes with the drive wheel to achieve power transmission. The tooth profile engagement further improves the stability of power transmission in high-horsepower scenarios. The U-shaped support heat-conducting frame is set inside the drive section along the width direction. The closed end of the support heat-conducting frame is set inside the drive tooth profile, which can improve the strength of the drive tooth profile and maintain its shape stability. The two sides of the open end of the support heat-conducting frame are respectively inside the two structural tooth profiles. The support heat-conducting frame can conduct the heat generated by the drive tooth profile to the vicinity of the gap between the structural tooth profiles and dissipate it, thereby improving the heat dissipation capacity of the drive belt. Based on the above scheme, the double-sided toothed belt in this application can better adapt to the transmission in high-horsepower scenarios. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0019] like Figures 1-3As shown in the figure, this embodiment proposes a double-sided toothed belt for a high-horsepower harvester. The double-sided toothed belt includes a pre-embedded frame 1 and a transmission part 2. One side of the transmission part 2 is provided with multiple transmission teeth 3, and the opposite side of the transmission teeth 3 is provided with multiple structural teeth 4. The pre-embedded frame 1 includes a tensile frame 5 and a supporting heat-conducting frame 6. The tensile frame 5 is pre-embedded in the transmission part 2 along the length direction of the transmission part 2. The supporting heat-conducting frame 6 has a U-shaped structure. The closed end of the supporting heat-conducting frame 6 is set in the transmission teeth 3, and the two sides of the open end of the supporting heat-conducting frame 6 are respectively set in two of the structural teeth 4.

[0020] In this embodiment, a double-sided toothed belt for a high-horsepower harvester is used in high-horsepower transmission scenarios. Its transmission section 2 has a pre-embedded frame 1, and different toothed structures are provided on both sides of the transmission section 2 to adapt it for transmitting greater power in high-horsepower scenarios. Firstly, the pre-embedded frame 1 in the transmission section 2 is divided into a tensile frame 5 and a supporting heat-conducting frame 6. The tensile frame 5 is pre-embedded in the transmission section 2 along its length, improving the tensile strength of the transmission section 2 in the length direction and preventing elongation and deformation caused by high-horsepower transmission. Furthermore, one side of the transmission section 2 is provided with transmission teeth 3, and the opposite side is provided with structural teeth 4. The tooth profile 3 meshes with the transmission wheel to achieve power transmission. The tooth profile further improves the stability of power transmission in high-horsepower scenarios. The U-shaped support heat-conducting frame 6 is set inside the transmission part 2 along the width direction of the transmission part 2. The closed end of the support heat-conducting frame 6 is set inside the transmission tooth profile 3, which can improve the strength of the transmission tooth profile 3 and maintain its shape stability. The two sides of the open end of the support heat-conducting frame 6 are respectively inside the two structural tooth profiles 4. The support heat-conducting frame 6 can conduct the heat generated by the transmission tooth profile 3 to the vicinity of the gap between the structural tooth profiles 4 and dissipate it, thereby improving the heat dissipation capacity of the transmission belt. Based on the above scheme, the double-sided toothed belt in this application can better adapt to the transmission in high-horsepower scenarios.

[0021] The height of the transmission tooth profile 3 is greater than the height of the structural tooth profile 4.

[0022] Based on the above embodiments, the height of the transmission tooth profile 3 is greater than the height of the structural tooth profile 4. The transmission tooth profile 3 is higher and has a stable fit with the transmission wheel. The structural tooth profile 4 is relatively smaller, which can reduce the material used in manufacturing the toothed belt while still meeting the heat dissipation space requirements of the heat-conducting frame 6.

[0023] The cross-section of the transmission part 2 along the width direction is trapezoidal.

[0024] Based on the above embodiments, the cross-section of the transmission part 2 along its width direction is trapezoidal, and when it is matched with the transmission wheel, the trapezoidal structure is more stable and reliable.

[0025] The bottom of the gap between adjacent transmission tooth profiles 3 is arc-shaped.

[0026] Based on the above embodiments, the bottom of the gap between the transmission teeth 3 is arc-shaped. When it is in contact with the transmission wheel, the arc-shaped bottom of the gap can reduce wear and extend the service life of the toothed belt.

[0027] The tensile skeleton 5 is configured as multiple parallel skeletons located on the same horizontal plane.

[0028] Based on the above embodiments, the tensile skeleton 5 can be configured as multiple skeletons. Within one horizontal cross section of the toothed belt, multiple tensile skeletons 5 are arranged in parallel to improve the tensile performance in a balanced manner. The tensile skeleton 5 is composed of a glass fiber weave and a tensile core. Multiple parallel and evenly distributed tensile cores are woven and inserted inside the glass fiber weave. The tensile core is a polyester fiber thread.

[0029] The thermally conductive support frame 6 includes multiple frames, and the thermally conductive support frame 6 is disposed between two adjacent tensile frames 5.

[0030] Based on the above embodiments, the heat-conducting support frame 6 can be arranged in multiple parallel configurations, with the heat-conducting support frame 6 placed on the tensile frame 5 support.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
