Description

Technical Field

[0001] This utility model relates to the field of transmission component technology, specifically a stamped synchronous wheel. Background Technology

[0002] Synchronous belt pulleys are commonly used transmission devices in industry, and are widely used in automobiles, light industry, textiles, food packaging, printing machinery, tobacco machinery, office automation equipment, home appliances, medical and health equipment, CNC machine tools and other fields. Synchronous belt drives involve pulleys and synchronous belts, and are a type of embedded meshing transmission. The synchronous belt pulley is a key component in a synchronous belt drive system, usually referring to the synchronous belt pulley installed on the right side of the transmission system, which meshes with the synchronous belt to transmit power or motion.

[0003] For example, a novel stamped synchronous wheel, as disclosed in patent publication number CN202992101U, includes a wheel body with a through hole in the thickness direction, and all solid parts of the wheel body except for the through hole have a consistent thickness. By adopting this technical solution, the through hole in the thickness direction and the consistent thickness of all solid parts mean that during the stamping process, parameters such as the thickness of the powder at the powder loading point remain consistent, resulting in uniform stamping pressure. The synchronous wheel is integrally formed. Compared with existing technologies, this effectively reduces stamping pressure, saving energy and material usage, while also lowering costs. Furthermore, the consistent thickness of the solid parts effectively overcomes the defects of traditional synchronous wheels, which suffer from uneven stamping pressure and internal cracks due to inconsistent thickness, different compression ratios and precision of powder forming, leading to easy breakage during use. This improves the overall strength and working performance of the synchronous wheel.

[0004] However, during the use of the above-mentioned equipment, due to the design of its internal wheel body, the synchronous wheel is prone to generating heat and noise during rapid rotation, causing environmental pollution and accelerating wear. Therefore, we propose a more convenient and practical synchronous wheel to meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a stamped synchronous wheel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamped synchronous wheel, comprising an annular support plate, with multiple equidistant noise-reducing grooves extending through the top of the annular support plate; at least two radially inner reinforcing ribs fixedly connected to multiple equidistant reinforcing ribs on the inner wall of the support plate; a connecting ring fixedly connected to one side of the reinforcing ribs; a clamping boss fixedly connected to one side of the connecting ring; a connecting hole extending through the center of one side of the clamping boss; and a wear-resistant plate fixedly connected to the outer side of the support plate, with multiple equidistant heat dissipation holes extending through one side of the wear-resistant plate.

[0007] Furthermore, the reinforcing rib has a trapezoidal cross-section, with one side welded and fixed to the inner wall of the support plate, and the other side fixedly connected to the outer wall of the connecting ring.

[0008] Furthermore, the outer wall of the wear-resistant plate is fixedly connected with multiple equidistant teeth, and the outer wall of the wear-resistant plate is provided with multiple equidistant heat dissipation grooves between the teeth.

[0009] Furthermore, the wear-resistant plate is integrally formed on the outer wall of the support plate by stamping, and its thickness is 0.6-0.8 times the thickness of the support plate. The heat dissipation hole is a circular through hole with a diameter of 3-8mm.

[0010] Furthermore, the axial height of the clamping boss is 2-5mm, and the top of the clamping boss is provided with a chamfer structure.

[0011] Furthermore, the heat dissipation groove is a straight groove arranged radially along the wear-resistant plate, with a groove depth of 2-5mm, and the tooth surface is provided with a hardened treatment layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This stamped synchronous pulley, through the setting of a support mechanism and a heat dissipation mechanism, works as follows: First, the power shaft passes through the clamping boss and is fixed. Then, the power shaft drives the gear to rotate, which in turn moves the meshing parts to achieve power transmission. During rotation, the main load is borne by the annular support plate and the stress is dispersed by the reinforcing ribs. Then, the teeth of the wear-resistant plate contact the mating parts to reduce wear. At the same time, the heat dissipation holes and heat dissipation grooves accelerate airflow and dissipate the heat generated during operation in a timely manner. Finally, the sound-absorbing grooves effectively reduce vibration noise. This device can effectively reduce vibration noise during operation, while reducing weight and improving energy efficiency. It also forms an air convection channel to further improve heat dissipation efficiency. It is highly practical and suitable for widespread application.

[0014] Meanwhile, the entire process is made using stamping, which is efficient and cost-effective, making it suitable for mass production. The trapezoidal reinforcing ribs and clamping bosses can be formed in one step using a mold, reducing subsequent processing. Attached Figure Description

[0019] 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.

[0020] Synchronous pulleys are required in the use of transmission equipment. Before installing the synchronous pulley provided by this invention, ensure that its surface is undamaged, the wear-resistant plate 7 is intact, and the heat dissipation holes 8 and heat dissipation grooves 10 are unobstructed to avoid affecting its performance and heat dissipation. Ensure that the clamping boss 5 fits tightly with the fixed part of the transmission equipment, and that the direction of the reinforcing rib 3 is consistent with the direction of the transmission force to improve the load-bearing capacity and transmission stability of the synchronous pulley. During use, the operating status of the synchronous pulley should be checked regularly, including the wear condition of the wear-resistant plate 7 and the cleanliness of the heat dissipation holes 8 and heat dissipation grooves 10. If any problems are found, replace or clean it promptly. Avoid overloading the transmission equipment during use to prevent excessive load on the synchronous pulley, which could damage it or affect the transmission effect.

[0021] like Figures 1-3 As shown, this utility model provides a technical solution: a stamped synchronous wheel, including an annular support plate 1. Multiple equidistant noise-reducing grooves 2 are formed through the top of the annular support plate 1. At least two radially inner reinforcing ribs 3 are fixedly connected to each other along their inner sides, with a connecting ring 4 fixedly connected to one side of each reinforcing rib 3. A clamping boss 5 is fixedly connected to one side of the connecting ring 4. A connecting hole 6 is formed through the center of one side of the clamping boss 5. A wear-resistant plate 7 is fixedly connected to the outer side of the support plate 1, with multiple equidistant heat dissipation holes 8 formed through one side of the wear-resistant plate 7. The reinforcing rib 3 has a trapezoidal cross-section, with one side welded to the inner wall of the support plate 1 and the other side fixedly connected to the outer wall of the connecting ring 4.

[0022] It should be noted that during use, when the material is stamped, it is squeezed by the mold to fill the sound-absorbing groove 2 of the annular support plate 1 and the heat dissipation hole 8 of the wear-resistant plate 7, forming a lightweight structure. The reinforcing rib 3 enhances the radial support force through the trapezoidal cross section design, and works with the connecting ring 4 to improve the resistance to deformation. Then, the power 2 passes through the connecting ring 4, the clamping boss 5 and the connecting hole 6 in sequence to fix it, ensuring transmission stability. Heat is transferred into the air through the heat dissipation hole 8. The integral stamping process ensures structural rigidity and avoids the risk of deformation or desoldering caused by welding.

[0023] like Figure 3 As shown, the outer wall of the wear-resistant plate 7 is fixedly connected with multiple equidistant teeth 9, and multiple equidistant heat dissipation grooves 10 are opened between the teeth 9 on the outer wall of the wear-resistant plate 7. The wear-resistant plate 7 is integrally formed on the outer wall of the support plate 1 by stamping, and its thickness is 0.6-0.8 times the thickness of the support plate 1. The heat dissipation hole 8 is a circular through hole with a diameter of 3-8mm. The axial height of the clamping boss 5 is 2-5mm. The top of the clamping boss 5 is provided with a chamfer structure. The heat dissipation groove 10 is a straight groove arranged radially along the wear-resistant plate 7, and its groove depth is 2-5mm. The surface of the teeth 9 is provided with a hardened treatment layer.

[0024] It should be noted that during use, the wear-resistant plate 7 rotates with the support plate 1, causing the teeth 9 to mesh with external components. Then, the heat dissipation groove 10 accelerates airflow and heat dissipation. The hardened teeth 9 improves wear resistance, while the circular heat dissipation holes 8 assist in cooling, ensuring long-term stable operation. The surface hardening treatment of the teeth 9 significantly improves wear resistance and extends service life. The heat dissipation groove 10 increases the heat dissipation area and accelerates heat dissipation.

[0025] During use, the power shaft first passes through the clamping boss 5 and is fixed. Then, the power shaft drives the tooth 9 to rotate, which drives the meshing parts to move and realize power transmission. During the rotation, the main load is borne by the annular support plate 1 and the stress is dispersed by the reinforcing rib 3. Then, the tooth 9 of the wear-resistant plate 7 contacts the mating parts to reduce wear. At the same time, the heat dissipation holes 8 and heat dissipation grooves 10 accelerate the air flow and dissipate the heat generated during operation in time. Finally, the sound-absorbing groove 2 effectively reduces vibration noise. This device can effectively reduce vibration noise during operation, reduce weight, improve energy efficiency, and form an air convection channel to further improve heat dissipation efficiency.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
