Description

Technical Field

[0001] This utility model relates to the field of transmission belt technology, specifically to a high wear-resistant harvester transmission belt. Background Technology

[0002] Rubber V-belts, also known as triangular belts or V-belts, are commonly used as drive belts. Currently, domestic V-belt structures consist of three main parts: a rubber skeleton (i.e., the winding), a rubber base, and an outer fabric layer. However, in high-power applications, traditional belts are prone to elongation and deformation after speed changes. The elongated and deformed belt generates relative friction with the drive pulley, leading to increased wear.

[0003] Based on the above problems, existing technologies often only consider increasing the wear resistance of the transmission belt. However, due to the deformation of the belt, the belt will still be subject to continuous friction, which does not effectively solve the above problems. Therefore, a new transmission belt is needed to address these issues. Utility Model Content

[0004] This invention proposes a high wear-resistant harvester transmission belt, which solves the problem of wear caused by deformation in existing transmission belts.

[0005] The technical solution of this utility model is as follows: A high wear-resistant harvester transmission belt includes a base rubber layer and a transmission layer body disposed on the base rubber layer. The transmission layer body includes a transmission inner core layer and a wear-resistant layer covering the transmission inner core layer. One side of the transmission inner core layer is connected to the base rubber layer, and the wear-resistant layer covers the other three sides of the transmission inner core layer. The transmission belt also includes an inner core skeleton and a wear-resistant skeleton. The inner core skeleton is disposed in the transmission inner core layer along its length direction. Multiple wear-resistant skeletons are disposed at equal intervals along the length direction in the wear-resistant layer. The shape of the wear-resistant skeleton is smaller than the cross-sectional outer contour shape of the wear-resistant layer and they are the same shape.

[0006] The outer contour of the wear-resistant layer cross section is trapezoidal.

[0007] The inner core skeleton is configured as multiple parallel skeletons.

[0008] The wear-resistant skeleton is provided with a rib skeleton at the bend, and the rib skeleton is located on the inside of the bend of the wear-resistant skeleton.

[0009] The surface of the wear-resistant skeleton is provided with a patterned groove.

[0010] The transmission belt also includes a buffer layer, which is disposed on the base rubber layer. The transmission inner core layer and the wear-resistant layer are both disposed on the buffer layer.

[0011] The working principle and beneficial effects of this utility model are as follows: This utility model discloses a high wear-resistant harvester transmission belt. Specifically, its structure includes a base rubber layer as the bottom layer, upon which a transmission layer body is set, serving as the main part that cooperates with the transmission wheel. The transmission layer body is divided into two parts: a transmission inner core layer and a wear-resistant layer. The wear-resistant layer covers the outside of the transmission inner core layer and its three sides. Because the transmission belt undergoes elongation and deformation, the portion of the belt within the transmission pulley contracts, reducing friction and causing slippage and wear. Therefore, an inner core skeleton is pre-embedded inside the transmission inner core layer, and a wear-resistant skeleton is pre-embedded inside the wear-resistant layer, enhancing its wear resistance. The wear-resistant skeletons are multiple and evenly spaced along the length of the transmission belt. The shape of the wear-resistant skeleton is smaller than the outer contour of the wear-resistant layer cross-section and the shape is the same. The inner core skeleton in the transmission inner core layer can improve the tensile strength of the belt and effectively delay the elongation of the belt during transmission. The wear-resistant skeleton can effectively maintain the shape stability of the part of the belt located in the transmission pulley, so that the transmission belt maintains stable contact, thereby avoiding slippage and reducing wear. By synergistically improving the stability of the length and contour of the transmission belt, the transmission belt can effectively overcome deformation, thereby improving wear and extending service life.

[0014] 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.

[0015] like Figures 1-2As shown in the figure, this embodiment proposes a high wear-resistant harvester transmission belt. The transmission belt includes a base rubber layer 1 and a transmission layer body 2 disposed on the base rubber layer 1. The transmission layer body 2 includes a transmission inner core layer 3 and a wear-resistant layer 4 covering the transmission inner core layer 3. One side of the transmission inner core layer 3 is connected to the base rubber layer 1, and the wear-resistant layer 4 covers the other three sides of the transmission inner core layer 3. The transmission belt also includes an inner core skeleton 5 and a wear-resistant skeleton 6. The inner core skeleton 5 is disposed in the transmission inner core layer 3 along the length direction. Multiple wear-resistant skeletons 6 are disposed at equal intervals along the length direction in the wear-resistant layer 4. The shape of the wear-resistant skeleton 6 is smaller than the cross-sectional outer contour shape of the wear-resistant layer 4 and the shape is the same.

[0016] This embodiment discloses a high wear-resistant harvester transmission belt. Specifically, its structure includes a base rubber layer 1 as the bottom layer, upon which a transmission layer body 2 is disposed. This transmission layer body 2 serves as the main component that engages with the transmission pulley. The transmission layer body 2 is divided into two parts: a transmission inner core layer 3 and a wear-resistant layer 4. The wear-resistant layer 4 covers the outside of the transmission inner core layer 3 and its three sides. Due to the elongation and deformation of the transmission belt, the portion of the belt within the transmission pulley contracts, reducing friction and causing slippage and wear. Therefore, an inner core skeleton 5 is pre-embedded inside the transmission inner core layer 3, and a wear-resistant skeleton 6 is pre-embedded inside the wear-resistant layer 4. Multiple wear-resistant skeletons 6 are evenly spaced along the length of the transmission belt, and the shape of the wear-resistant skeleton 6 is smaller than the cross-section of the wear-resistant layer 4. The outer contours are identical; the inner core skeleton 5 within the transmission inner core layer 3 improves the tensile strength of the belt, effectively delaying belt elongation during transmission. The wear-resistant skeleton 6 effectively maintains the stability of the belt's shape within the transmission pulley. For example, the inner core skeleton 5 can be composed of a glass fiber weave and a tensile core. Multiple parallel and evenly distributed tensile cores are woven and inserted within the glass fiber weave. The tensile cores can be made of polyester fiber yarn, while the wear-resistant skeleton 6 can be made of a relatively rigid material to maintain the shape of the transmission belt. For example, the wear-resistant skeleton 6 can be made of metal, such as aluminum alloy. Through the above scheme, the transmission belt maintains stable contact, thereby preventing slippage and reducing wear.

[0017] The outer contour of the wear-resistant layer 4 is trapezoidal.

[0018] Based on the above embodiments, the outer contour of the wear-resistant layer 4 is trapezoidal, and the shape of the wear-resistant skeleton 6 is also trapezoidal. It should be noted that the trapezoid here is an open trapezoid without a bottom side. The size of the wear-resistant skeleton 6 is smaller than the size of the wear-resistant layer 4, so that the wear-resistant skeleton 6 can be pre-embedded in the wear-resistant layer 4. The trapezoidal wear-resistant layer 4 can form a larger contact area with the transmission groove wheel, improving the stability of the transmission.

[0019] The inner core skeleton 5 is configured as multiple parallel skeletons.

[0020] Based on the above embodiments, multiple inner core skeletons 5 can be set in the transmission inner core layer 3, and the multiple inner core skeletons 5 can be arranged in parallel. The multiple inner core skeletons 5 are symmetrically arranged in the cross section of the transmission inner core layer 3 along the width direction. For example, four inner core skeletons 5 can be set, and the four inner core skeletons are axially symmetrically arranged in the cross section of the transmission inner core layer 3 along the width direction. By adopting this arrangement, the tensile strength of the inner core skeletons 5 can be more balanced.

[0021] The wear-resistant skeleton 6 is provided with a rib skeleton 7 at the bend, and the rib skeleton 7 is located on the inside of the bend of the wear-resistant skeleton 6.

[0022] Based on the above embodiments, the wear-resistant skeleton 6 and the wear-resistant layer 4 have the same cross-sectional outer contour shape along the width direction, which is also trapezoidal. A rib skeleton 7 is also provided at the bend of the trapezoid. The rib skeleton 7 improves the deformation resistance of the wear-resistant skeleton 6, thereby better maintaining the stability of the external shape of the wear-resistant layer 4.

[0023] The surface of the wear-resistant skeleton 6 is provided with a patterned groove 8.

[0024] Based on the above embodiments, patterned grooves 8 can be machined on the surface of the wear-resistant skeleton 6 and embedded in the wear-resistant layer 4 to improve the tightness of the bond between the wear-resistant layer 4 material and the wear-resistant skeleton 6.

[0025] The transmission belt also includes a buffer layer 9, which is disposed on the base rubber layer 1. The transmission inner core layer 3 and the wear-resistant layer 4 are both disposed on the buffer layer 9.

[0026] Based on the above embodiments, a buffer layer 9 is further provided on the base rubber layer 1. The buffer layer 9 can be made of a material that can absorb vibration and impact. For example, a layer of rubber is used to absorb the vibration of the transmission belt during operation and protect the base rubber layer 1.

[0027] 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.
