Description

Technical Field

[0001] This utility model relates to the field of transmission belt technology, specifically to a high synchronization rate coupled transmission V-belt. Background Technology

[0002] A V-belt is used to transmit the power generated by the rotation of a motor or engine in a prime mover to mechanical equipment through pulleys. It is also called a power belt. It is a core connecting component of electromechanical equipment, and there are many different types with extremely wide applications.

[0003] In some scenarios with high transmission power, multiple V-belts need to be used simultaneously. However, when multiple V-belts are used at the same time, the transmission synchronization of each V-belt is different. Especially as the usage time increases, the difference in synchronization becomes more obvious, affecting the transmission efficiency. Therefore, based on the above problems, a new type of V-belt is needed to solve the problem. Utility Model Content

[0004] This invention proposes a high-synchronization-rate combined transmission V-belt, which solves the problem of inconsistent transmission synchronization among multiple transmission V-belts in the prior art.

[0005] The technical solution of this utility model is as follows: A high-synchronization-rate coupled drive V-belt includes a base rubber layer and multiple drive layers arranged parallel to the base rubber layer. Adjacent drive layers are connected on the side closest to the base rubber layer. The belt also includes a rubber skeleton, which includes a support skeleton and a linkage skeleton. The support skeleton is disposed within the drive layers, and the linkage skeleton is disposed within the drive layers on the side closest to the base rubber layer. The linkage skeleton passes through the multiple drive layers in sequence.

[0006] The support frame includes multiple support bars parallel to the length direction of the transmission layer.

[0007] The linkage frame includes multiple support bars perpendicular to the length direction of the transmission layer.

[0008] The transmission layer also has a wear-resistant layer on the friction surface used for transmission.

[0009] The adjacent transmission layers are separated by V-shaped grooves.

[0010] The base layer includes a tensile layer and a buffer layer, with the buffer layer disposed inside the tensile layer, and multiple transmission layers disposed on the buffer layer.

[0011] The working principle and beneficial effects of this utility model are as follows: This invention discloses a high-synchronization-rate linked transmission V-belt. Multiple transmission layers are arranged on a base rubber layer, with adjacent transmission layers connected on the side closest to the base rubber layer. A support frame is arranged within each transmission layer, and a linkage frame is arranged on the side of each transmission layer closest to the base rubber layer. The linkage frame passes sequentially through multiple transmission layers. The linkage frame and the support frame together form the rubber skeleton of the transmission V-belt. During transmission, the support frame within the transmission layer improves the shape stability of a single transmission layer, while the linkage frame improves the synchronization rate of movement between different transmission layers during transmission, thereby maintaining relatively stable power transmission.

Detailed Implementation

[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 1-2 As shown, this embodiment proposes a high synchronization rate coupled drive V-belt. The coupled drive V-belt includes a base rubber layer 1 and multiple drive layers 2 arranged parallel to the base rubber layer 1. Adjacent drive layers 2 are connected on the side closer to the base rubber layer 1. The coupled drive V-belt also includes a rubber skeleton 3, which includes a support skeleton 4 and a linkage skeleton 5. The support skeleton 4 is disposed within the drive layers 2, and the linkage skeleton 5 is disposed within the drive layers 2 on the side closer to the base rubber layer 1. The linkage skeleton 5 passes through the multiple drive layers 2 in sequence.

[0016] In this embodiment, a high-synchronization-rate connected V-belt is proposed. Multiple parallel transmission layers 2 are arranged on the base rubber layer 1. During use, the transmission layers 2 are engaged in the grooves of the pulleys to form a transmission. To further improve the transmission synchronization rate of each transmission layer 2, the structure of the transmission layers 2 is optimized. At the end of the transmission layer 2 near the base rubber layer 1, adjacent transmission layers 2 are connected, unlike the traditional disconnected structure. A support frame 4 is provided within the transmission layer 2 to improve its shape stability. Additionally, a linkage frame 5 is provided, which passes through the end of the transmission layer 2 near the base rubber layer 1 and sequentially through multiple transmission layers 2. During transmission, the synchronization rate of adjacent transmission layers 2 is greatly improved by the series connection of the linkage frames 5 and the optimized bottom structure of the transmission layers 2.

[0017] The support frame 4 includes multiple support bars parallel to the length direction of the transmission layer 2.

[0018] The linkage frame 5 includes multiple support bars perpendicular to the length direction of the transmission layer 2.

[0019] Based on the above embodiments, the support frame 4 and the linkage frame 5 together form the rubber frame 3. A possible implementation is that the support frame 4 is a support strip disposed within the transmission layer 2 along its length, providing stable support for the shape of the transmission layer 2. The linkage frame 5 is disposed at one end of the transmission layer 2 near the bottom rubber layer 1. The linkage frame 5 is arranged with support strips perpendicular to the length of the transmission layer 2, passing sequentially through multiple transmission layers 2. When multiple transmission layers 2 are driven on the pulley, the linkage frame 5 provides synchronous lifting for adjacent transmission layers 2. For example, the rubber strip can be composed of a glass fiber weave and a tensile core. Multiple parallel and evenly distributed tensile cores are woven into the glass fiber weave. The tensile cores can be polyester fiber yarns.

[0020] The friction surface of the transmission layer 2 used for transmission is also provided with a wear-resistant layer 6.

[0021] In this embodiment, a wear-resistant layer 6 is also provided on the transmission layer 2. The wear-resistant layer 6 is mainly distributed on the surface of the transmission layer 2 that contacts the inner wall of the pulley groove. The specific area can be flexibly designed according to the actual situation. For example, the wear-resistant layer 6 can be processed by combining a cloth material with a rubber formula.

[0022] The adjacent transmission layers 2 are connected by V-shaped grooves.

[0023] In this embodiment, there is a V-groove between adjacent transmission layers 2, which facilitates assembly with pulleys to form a transmission connection.

[0024] The base layer 1 includes a tensile layer 7 and a buffer layer 8. The buffer layer 8 is disposed inside the tensile layer 7, and multiple transmission layers 2 are disposed on the buffer layer 8.

[0025] In this embodiment, the base layer 1 includes a tensile layer 7 and a buffer layer 8. The tensile layer 7 has resistance to bending fracture and tensile strength, while the buffer layer 8 is a layer of rubber that absorbs vibrations caused by the transmission layer 2 during transmission. The above is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
