Description

Technical Field

[0001] The utility model relates to the field of belt pulleys, and particularly relates to a double-wheel combined spinning belt pulley for preventing deformation. Background Art

[0002] Generally, belt pulleys are relatively large in size. In manufacturing processes, casting and forging are mainly used. For larger-sized belt pulleys, the casting method is designed, and the material is mostly cast iron. For smaller-sized belt pulleys, forging is designed, and the material is steel. The structure of belt pulleys is relatively simple, easy to adjust, and the manufacturing and installation accuracy requirements for belt pulleys are not as strict as those for meshing transmissions. The double-wheel combined spinning belt pulley belongs to one type of belt pulleys. A double-wheel combined spinning belt pulley refers to a belt pulley composed of two large outer wheels and small outer wheels with the shape of hollow rings and coaxial centers. These two outer wheels are processed by a spinning process and extend a common wheel body. The outer side surfaces of the rings of each outer wheel are provided with grooved teeth for installing the belt, which is used for power transmission.

[0003] During the use of the existing double-wheel combined spinning belt pulley, due to different application scenarios of the double-wheel combined spinning belt pulley, the double-wheel combined spinning belt pulley is prone to being impacted and working in a harsh environment, and will be affected by the environment and thus deformed. If the double-wheel combined spinning belt pulley lacks the ability to prevent deformation, the deformation of the double-wheel combined spinning belt pulley will damage the original transmission accuracy, resulting in inaccurate transmission ratio or unstable transmission process. At the same time, it will also cause the belt to jump and slip during the transmission process, thereby generating additional noise and vibration, which directly affects the overall performance of the equipment. In the long run, it will also lead to problems such as decreased equipment performance and frequent failures.

[0004] Therefore, it is very necessary to invent a double-wheel combined spinning belt pulley for preventing deformation to solve the above problems. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a double-wheel combined spinning pulley that prevents deformation. Through the pulley deep groove, side stiffening ribs, fixing bolts, wheel deep groove sleeve, connecting shaft groove, and connecting rotating shaft rod, the double-wheel combined spinning pulley is enabled to have the ability to prevent deformation. When the double-wheel combined spinning pulley works in an environment vulnerable to impact and harsh conditions, the probability of deformation can be reduced, providing a certain anti-deformation ability. At the same time, the connecting rotating shaft rod is connected and installed with the double-wheel combined spinning pulley through the connecting shaft groove, docking card slot, and docking block. Such a fitting design can ensure the synchronism and stability of the two during the rotation process, and also helps to reduce the vibration and offset generated during rotation, thereby reducing the risk of deformation of the double-wheel combined spinning pulley, as well as problems such as the jumping and slipping of the belt during transmission, reducing noise and vibration, and ensuring the overall performance of the equipment. This is to solve the problems in the prior art that during the use of the double-wheel combined spinning pulley, due to different application scenarios of the double-wheel combined spinning pulley, when the double-wheel combined spinning pulley works in an environment vulnerable to impact and harsh conditions, it will be affected by the environment and deform. If the double-wheel combined spinning pulley lacks the ability to prevent deformation, the deformation of the double-wheel combined spinning pulley will destroy the original transmission accuracy, resulting in inaccurate transmission ratio or unstable transmission process. At the same time, it will also cause the jumping and slipping of the belt during transmission, thereby generating additional noise and vibration, directly affecting the overall performance of the equipment. In the long run, it will also lead to problems such as the decline of equipment performance and frequent failures.

[0008] A connecting shaft groove is arranged inside the small combined spinning pulley body and is used to install a rotating shaft. A docking card slot is opened inside the connecting shaft groove. A docking block is movably connected inside the docking card slot. One end of the docking block is fixedly installed with a connecting rotating shaft rod.

The design of the anti-slip lines significantly increases the contact area between the wheel deep groove sleeve and the belt, thereby enhancing the friction force between them. This increased friction force helps to prevent the belt from slipping during the transmission process, ensuring the continuity and stability of power transmission. Brief Description of the Drawings

[0026] The present utility model provides a double-wheel combined spinning pulley for preventing deformation as shown in Figures 1-5 Figure, which includes a large combined spinning pulley body 1, a pulley main body for driving the belt to rotate;

[0027] A small combined spinning pulley body 2 is arranged outside the large combined spinning pulley body 1 and is used to combine with the large combined spinning pulley body 1. A pulley deep groove 3 is opened on the outside of the large combined spinning pulley body 1. A side stiffening rib 4 is fixedly installed inside the pulley deep groove 3. A fixing bolt 5 penetrates through the inside of the pulley deep groove 3. One end of the fixing bolt 5 is movably connected to a wheel deep groove sleeve 6;

[0028] A communicating shaft groove 9 is arranged inside the small combined spinning pulley body 2 and is used for installing a rotating shaft. A docking card slot 10 is opened inside the communicating shaft groove 9. A docking card block 11 is movably connected inside the docking card slot 10. One end of the docking card block 11 is fixedly installed with a communicating rotating shaft rod 12. A small wheel disc reinforcing groove 13 is opened on one side of the small combined spinning pulley body 2. The communicating rotating shaft rod 12 is connected and installed with the double-wheel combined spinning pulley through the communicating shaft groove 9, the docking card slot 10 and the docking card block 11. Such a fitting design can ensure the synchronism and stability of the two during the rotation process, and also helps to reduce the vibration and offset generated during the rotation, thereby reducing the risk of deformation of the double-wheel combined spinning pulley.

[0029] As shown in Figure 1 、 Figure 2 and Figure 3 Figure, the number of the side stiffening ribs 4 is set to be multiple, and the multiple side stiffening ribs 4 are evenly distributed on the pulley deep groove 3. The side stiffening ribs 4 arranged on both sides of the pulley deep groove 3 can enhance the structural strength on both sides of the pulley deep groove 3, improve the overall rigidity of the double-wheel combined spinning pulley, avoid the occurrence of stress concentration phenomenon, ensure that it can bear the force evenly when carrying, effectively prevent deformation. An embedded groove 7 is opened inside the wheel deep groove sleeve 6. Anti-slip lines 8 are fixedly installed inside the wheel deep groove sleeve 6. Multiple groups of anti-slip lines 8 are arranged on the surface of the wheel deep groove sleeve 6. The design of the anti-slip lines 8 significantly increases the contact area between the wheel deep groove sleeve 6 and the belt, and further enhances the friction between them. This increased friction helps to prevent the belt from slipping during the transmission process, ensuring the continuity and stability of power transmission.

[0030] As shown in Figure 1 、 Figure 4 and Figure 5As shown in the figure, the docking block 11 fixedly installed outside the connecting rotating shaft rod 12 is engaged with the docking slot 10 opened inside the connecting shaft groove 9.

On one side of the large combined spinning pulley body 1, a large wheel disc reinforcement groove 16 is provided. A connecting bolt 17 penetrates through the inside of the large wheel disc reinforcement groove 16. One end of the connecting bolt 17 is movably connected with an outer large wheel reinforcement disc 18. Similarly, the outer large wheel reinforcement disc 18 and the connecting bolt 17 also strengthen the firmness of the connection between the other end of the connecting rotating shaft rod 12 and the large combined spinning pulley body 1.

[0031] Working principle of this utility model: Firstly, when using this double-wheel combined spinning pulley, first install the wheel deep groove sleeve 6 on the large combined spinning pulley body 1 and the small combined spinning pulley body 2 of the double-wheel combined spinning pulley. Since both the large combined spinning pulley body 1 and the small combined spinning pulley body 2 are provided with pulley deep grooves 3, the deeper wheel grooves can better support the belt, reduce the vibration and offset generated during the belt transmission, thereby reducing the risk of pulley deformation. Then, the side stiffening ribs 4 arranged on both sides of the pulley deep groove 3 can enhance the structural strength on both sides of the pulley deep groove 3, improve the overall rigidity of the double-wheel combined spinning pulley, avoid the occurrence of stress concentration phenomenon, ensure that it can be evenly stressed when bearing, and effectively prevent deformation. Next, take out the wheel deep groove sleeve 6, and use the fixing bolt 5 through the embedded groove 7 of the wheel deep groove sleeve 6 to install the wheel deep groove sleeve 6 on the large combined spinning pulley body 1 and the small combined spinning pulley body 2. In this way, after the belt is installed, the fixing bolt 5 can reduce the influence on the belt rotation, and can further increase the support area and transmission stability of the belt. Subsequently, multiple groups of anti-slip lines 8 are arranged on the surface of the wheel deep groove sleeve 6. The design of the anti-slip lines 8 significantly increases the contact area between the wheel deep groove sleeve 6 and the belt, thereby enhancing the friction between them. This increased friction helps to prevent the belt from slipping during the transmission process, ensuring the continuity and stability of power transmission. After the wheel deep groove sleeve 6 is installed, the belt can be sleeved outside the large combined spinning pulley body 1 and the small combined spinning pulley body 2. Then, take out the connecting rotating shaft rod 12 and connect and install it with the double-wheel combined spinning pulley through the connecting shaft groove 9, the docking card slot 10 and the docking block 11. Such a fitting design can ensure the synchronism and stability of the two during the rotation process, and also helps to reduce the vibration and offset generated by the rotation, thereby reducing the risk of deformation of the double-wheel combined spinning pulley, and also reducing problems such as the jumping and slipping of the belt during the transmission process, reducing noise and vibration. In this way, the installation of the double-wheel combined spinning pulley is completed, and the external machinery can be connected to the connecting rotating shaft rod 12 to drive the double-wheel combined spinning pulley to rotate. Such a design enables the double-wheel combined spinning pulley to have the ability to prevent deformation, and can reduce the probability of deformation when the double-wheel combined spinning pulley works in an environment vulnerable to impact and harsh conditions, providing a certain anti-deformation ability. Finally, after completing all the installation and use work of the double-wheel combined spinning pulley according to the above operations, only need to maintain the device daily. Just like this, the use process of the anti-deformation double-wheel combined spinning pulley is completed.
