Description

Technical Field

[0001] This utility model relates to the field of transmission belt technology, specifically a photovoltaic precision high-speed transmission synchronous belt. Background Technology

[0002] Drive belts are core components in mechanical equipment for power transmission and motion control. Working in conjunction with pulleys, they efficiently transmit power from the drive shaft to the driven shaft, and are widely used in industrial manufacturing, automotive, home appliances, medical equipment, and other fields. Their performance directly affects the operating accuracy, stability, and service life of the equipment; therefore, it is necessary to select the appropriate type based on different application scenarios.

[0003] Existing precision high-speed transmissions rely on the precise meshing of synchronous belts and pulleys. Therefore, the requirements for "coaxiality, parallelism, and center distance accuracy" during installation are much higher than those for ordinary transmission belts. As a result, precision instruments are required for installation, making the assembly process time-consuming and labor-intensive, and requiring specialized personnel for installation. Moreover, if the belt is under alternating overload conditions for a long time, such as frequent start-stop and load fluctuations, "bending fatigue stress" will be generated at the root of the belt teeth. At high speeds, the fatigue crack propagation rate accelerates, which can easily lead to problems such as tooth root fracture and tooth surface cracking.

[0004] Therefore, it does not meet the existing requirements, so we propose a photovoltaic precision high-speed transmission synchronous belt. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 A photovoltaic precision high-speed transmission synchronous belt includes a belt body 1 and teeth 10. The belt body 1 is connected end to end to form an annular belt 11. The belt body 1 has an integral structure and is fitted between two pulleys 3 in the transmission structure. The integral structure of the belt body 1 can be fitted between two pulleys 3 in the transmission structure for power transmission.

[0023] refer to Figure 3 and Figure 4 The belt body 1 is made of TPU material. A protective layer 2 is provided on the annular belt 11, covering both the inner and outer ring walls of the annular belt 11. The protective layer 2 is a nylon fiber layer. A tensile layer 13 is provided inside the belt body 1. The tensile layer 13 consists of several parallel steel wires 130, which are wrapped around the belt body 1. The steel wires 130 are spirally woven from fine metal wires. TPU material is polyester fiber material. The belt body 1, directly extruded from TPU material, has high hardness and stronger rigidity. It has a low compression deformation rate during long-term use and can maintain good shape and performance over extended periods. It is suitable for high-precision transmission structures. The tensile layer 13 composed of steel wire 130 gives the belt body 1 high resistance to breakage. The inner and outer ring walls of the belt body 1 are provided with protective layers 2. The protective layer 2, which is made of nylon fiber, has high tensile strength, so that the transmission belt can withstand large tensile forces and is not easy to break. The annular belt 11, which is composed of the protective layer 2 made of nylon fiber and the belt body 1 made of TPU material directly extruded, is not easy to deform and will not produce fatigue cracks. It also has strong wear resistance and rigidity, making it suitable for high-precision transmission structures.

[0024] refer to Figures 1-5A number of teeth 10 are equidistantly arranged on the inner side of the annular belt 11. Each tooth 10 has a tooth groove 12. The annular belt 11 has a positioning groove 110 along its inner ring wall. The positioning groove 110 divides the teeth 10 into two parts: a left tooth 100 and a right tooth 101. The left tooth 100 and the right tooth 101 are symmetrically distributed along the center line of the positioning groove 110. The pulley 3 has a groove 30 for the annular belt 11 to be fitted. The groove 30 has a positioning rail 300 embedded in the positioning groove 110. The positioning groove 110 divides all the teeth 10 into two parts: a left tooth 100 and a right tooth 101. The positioning rail 300 is provided on the pulley 3 corresponding to the annular belt 11 so that the belt body 1 can be accurately installed between the two pulleys 3. This avoids the problem that existing high-precision transmission belts require precision instruments for auxiliary installation, which makes the assembly very troublesome. It also avoids the problem of the belt body 1 jumping during operation, thereby reducing the number of maintenance and lowering the cost of use.

[0025] refer to Figures 2-4 The tooth groove 12 and the positioning groove 110 are perpendicular to each other, and the lowest surface of the tooth groove 12 and the lowest surface of the positioning groove 110 are located on the same plane. The cross-sectional profile of the tooth 10 and the cross-sectional profile of the tooth groove 12 are opposite to the arc-shaped structure. The connection between the outer wall of the tooth 10 and the outer wall of the tooth groove 12 is smooth. The tooth 10 is separated by the tooth groove 12, and the end of the tooth 10 and the top of the tooth groove 12 are smoothly connected, so that the belt 1 can maintain a stable fit when it contacts the pulley 3, reducing the contact gap between the two and thus improving the transmission efficiency. Furthermore, since the lowest surface of the tooth groove 12 and the lowest surface of the positioning groove 110 are located on the same plane, it can effectively prevent the positioning rail 300 on the pulley 3 from wearing the left tooth 100 and the right tooth 101.

[0026] When assembling the belt body 1, the annular belt 11 is fitted onto the positioning rail 300 of the pulley 3 through the positioning groove 110. At this time, the left tooth 100 and the right tooth 101 located at the pulley 3 are respectively located on the left and right sides of the positioning rail 300 and mesh with the teeth on the pulley 3. The end of the tooth 10 smoothly transitions with the top of the tooth groove 12, so that the belt body 1 can maintain a stable fit when contacting the pulley 3, avoiding the problem of the belt body 1 jumping during operation, thereby reducing the number of maintenance and lowering the cost of use. Moreover, during installation, high-precision positioning can be completed directly through the positioning groove 110 and the positioning rail 300, thus avoiding the need for precision instruments to assist in installation. During use, the belt body 1 is fitted between the two pulleys 3 in the transmission structure for power transmission. The annular belt 11, which is composed of a protective layer 2 woven from nylon fiber and a belt body 1 directly extruded from TPU material, is not easily deformed, will not produce fatigue cracks, and has strong wear resistance and rigidity.

[0027] In summary, the positioning groove 110 divides the toothed part 10 into a left tooth 100 and a right tooth 101, and a positioning rail 300 that can be embedded in the positioning groove 110 is provided on the pulley 3 to position the belt body 1, preventing the belt body 1 from deviating and jumping during use. Moreover, during installation, the two can be used together to achieve quick and accurate positioning, simplifying the installation steps. Furthermore, the protective layer 2 made of nylon fiber weaving, the belt body 1 made of TPU material directly extruded, and the tensile layer 13 composed of steel wire 130 work together to give this annular belt 11 high hardness and stronger rigidity. It has a low compression deformation rate during long-term use and can maintain good shape and performance during long-term use. This makes the belt body 1 less prone to breakage, deformation, and fatigue cracking when subjected to large tensile forces.
