Description

Technical Field

[0001] This utility model belongs to the field of synchronous belt pulley technology, specifically a wear-resistant synchronous belt pulley anti-slip tooth groove structure. Background Technology

[0002] Synchronous belt pulleys are mechanical components that transmit power by meshing with synchronous belts. They are widely used in industrial automation, automobiles, medical equipment and other fields. Their core function is to transmit motion and power through the precise meshing of belt teeth and pulley teeth. They have the characteristics of constant transmission ratio and high efficiency and energy saving. They are widely used in automobiles, printing and packaging equipment, sewing equipment, laser engraving equipment, medical machinery, steel machinery and other fields.

[0003] When in use, a synchronous belt pulley is driven by a closed annular rubber belt with equally spaced teeth on its inner circumference. During movement, the belt teeth mesh with the grooves of the pulley to transmit motion and power. It is a meshing transmission and therefore has the characteristics of gear transmission and flat belt transmission.

[0004] However, when the synchronous belt pulley transmission is under heavy load or at high speed, relative slippage can easily occur between the synchronous belt and the pulley, which will accelerate the wear of the synchronous belt, reduce the transmission accuracy, and even cause equipment failure. Therefore, the anti-slip properties of the synchronous belt pulley tooth groove are particularly important. To address the above problems, a wear-resistant anti-slip tooth groove structure for synchronous belt pulleys is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem of poor anti-slip properties of synchronous belt pulley tooth grooves, this utility model proposes a wear-resistant synchronous belt pulley anti-slip tooth groove structure.

The groove anti-slip mechanism includes side tooth surfaces symmetrically opened on both sides of the pulley grooves, a plurality of anti-slip side grooves are evenly opened on the two side tooth surfaces, a bottom transition tooth surface is opened below the pulley grooves, the bottom transition tooth surface connects the two corresponding upper side tooth surfaces, a bottom auxiliary groove is opened below the bottom transition tooth surface, a plurality of upper transition tooth surfaces are evenly arranged on the outer side of the synchronous pulley body, and side retaining rings are fixedly arranged on both sides of the synchronous pulley body, and auxiliary anti-slip mechanisms are provided on the side retaining rings.

[0007] Preferably, the bottom auxiliary groove extends along the length direction of the bottom transition tooth surface, and the cross-section of the bottom auxiliary groove is V-shaped.

[0008] Preferably, the upper transition tooth surface is located between two adjacent pulley tooth grooves, and the two sides of the upper transition tooth surface are connected to the corresponding side tooth surfaces.

[0009] Preferably, the auxiliary anti-slip mechanism includes a limiting ring detachably disposed on the inner side of the side retaining ring. The limiting ring includes two limiting half-rings. A pad is fixedly disposed on the inner side of the limiting half-ring. A plurality of pad grooves are evenly opened on the pad. A plurality of mounting holes are opened on the limiting half-ring.

[0024] Specific implementation examples are given below.

[0025] This application discloses a wear-resistant anti-slip tooth groove structure for a timing belt pulley. (Refer to...) Figures 1-5A wear-resistant anti-slip tooth groove structure for a synchronous belt pulley includes a synchronous belt pulley body 1. The synchronous belt pulley body 1 is made of high-strength steel, giving it good rigidity. Multiple pulley tooth grooves 2 are evenly distributed on the outer circumference of the synchronous belt pulley body 1. The pulley tooth grooves 2 are used for the meshing of the synchronous belt teeth. Transmission is achieved through the synchronous belt and the pulley tooth grooves 2. An anti-slip mechanism is provided on the pulley tooth grooves 2 to prevent relative slippage between the synchronous belt and the synchronous belt pulley body 1 when the synchronous belt transmission load is large or the speed is high, thus preventing accelerated wear of the synchronous belt and a decrease in transmission accuracy. The anti-slip mechanism includes symmetrically distributed side tooth surfaces 3 on both sides of the pulley tooth grooves 2. Multiple anti-slip side grooves 4 are evenly distributed on the two side tooth surfaces 3. The anti-slip side grooves 4 enhance the meshing tightness of the synchronous belt teeth on the two side tooth surfaces 3, effectively improving anti-slip capability. A bottom transition tooth surface 5 is provided below the pulley tooth grooves 2 to enhance the meshing of the synchronous belt teeth. To ensure the stability of the meshing at the ends and prevent relative slippage between the synchronous pulley and the synchronous belt during transmission, which would exacerbate wear on the synchronous belt and reduce transmission accuracy, the bottom transition tooth surface 5 connects the two corresponding side tooth surfaces 3 above. A bottom auxiliary groove 6 is provided below the bottom transition tooth surface 5. Multiple upper transition tooth surfaces 7 are evenly arranged on the outer side of the synchronous pulley body 1. Side retaining rings 8 are fixedly arranged on both sides of the synchronous pulley body 1. An auxiliary anti-slip mechanism is provided on the side retaining rings 8. Through the structure of the auxiliary anti-slip mechanism, side retaining rings 8 are fixedly arranged on both sides of the synchronous pulley body 1, and two limiting half rings 10 are installed inside the side retaining rings 8, which can effectively limit the axial displacement of the synchronous belt and avoid poor meshing and slippage caused by lateral offset. At the same time, the pad layer 11 can reduce impact and noise, and multiple pad grooves 12 are evenly opened on the pad layer 11 to improve the impact resistance of the pad layer 11.

[0026] Reference Figure 3 and Figure 4 The bottom auxiliary groove 6 extends along the length of the bottom transition tooth surface 5, and the cross-section of the bottom auxiliary groove 6 is set in a V-shape. Through the structure of the bottom auxiliary groove 6, it can contact and mesh with the synchronous belt tooth shape, increase the contact area and meshing tightness, effectively improve the anti-slip ability, and store a small amount of lubricant in the bottom auxiliary groove 6, which reduces wear and forms a small negative pressure on the surface, enhances the adsorption force, and further improves the anti-slip effect.

[0027] Reference Figure 2 The upper transition tooth surface 7 is located between two adjacent pulley tooth grooves 2, and the two sides of the upper transition tooth surface 7 are connected to the corresponding side tooth surfaces 3. The upper transition tooth surface 7 can contact and mesh with the synchronous belt tooth shape, increasing the contact area and meshing tightness, and effectively improving the anti-slip ability.

[0028] Reference Figure 1 and Figure 5The auxiliary anti-slip mechanism includes a detachable limiting ring 9 installed inside the side retaining ring 8. The limiting ring 9 includes two limiting half-rings 10. A pad 11 is fixedly installed inside the limiting half-ring 10. Multiple pad grooves 12 are evenly opened on the pad 11. Multiple mounting holes 13 are opened on the limiting half-ring 10. The limiting ring 9 is made of stainless steel. Through the structural setting of the auxiliary anti-slip mechanism, the side retaining rings 8 are fixedly installed on both sides of the pulley body 1 of the synchronous belt pulley, and the two limiting half-rings 10 are installed inside the side retaining rings 8. This can effectively limit the axial displacement of the synchronous belt and avoid poor meshing and slippage caused by lateral offset. At the same time, the pad 11 can reduce impact and noise, and the multiple pad grooves 12 are evenly opened on the pad 11 to improve the impact resistance of the pad 11.

[0029] Reference Figure 1 A reinforcing frame 14 is fixedly installed on the synchronous belt pulley body 1. The reinforcing frame 14 is made of tungsten alloy, which has good rigidity, thereby improving the impact resistance of the synchronous belt pulley body 1 and enhancing the overall rigidity of the synchronous belt pulley body 1. A mounting shaft 15 is fixedly installed on the shaft of the synchronous belt pulley body 1. A mounting keyway 16 is provided on the mounting shaft 15, which facilitates the installation of the synchronous belt pulley body 1 on the equipment shaft through the mounting keyway 16 on the mounting shaft 15, thereby facilitating the installation of the synchronous belt pulley body 1 and making it easier to use in the future.

[0030] Reference Figure 1 and Figure 3 The surface of the pulley tooth groove 2 is coated with a wear-resistant and anti-slip coating with a thickness of 0.05mm-0.1mm. By coating the pulley tooth groove 2 with a wear-resistant and anti-slip coating, the wear resistance of the pulley tooth groove 2 is improved and the wear of the pulley tooth groove 2 is reduced, thereby avoiding relative slippage between the synchronous belt and the synchronous pulley body 1 when the synchronous belt pulley drive has a large load or high speed.

[0031] Working principle: The operator installs the timing pulley body 1 on the equipment shaft through the mounting keyway 16 on the mounting shaft 15, thereby installing the timing pulley body 1 and adjusting the timing belt so that the teeth of the timing belt mesh with the pulley tooth groove 2 of the timing pulley body 1.

[0032] By designing an anti-slip mechanism in the tooth grooves, relative slippage between the synchronous belt and the pulley body 1 is prevented when the synchronous belt pulley is under heavy load or at high speed. This prevents increased wear on the pulley tooth grooves 2 and reduces transmission accuracy. Symmetrical side tooth surfaces 3 are provided on both sides of the pulley tooth grooves 2, and multiple anti-slip side grooves 4 are evenly distributed on these surfaces. These anti-slip side grooves 4 enhance the meshing tightness of the synchronous belt teeth on the two side tooth surfaces 3, effectively improving anti-slip capability. Furthermore, a bottom transition tooth surface 5 is provided below the pulley tooth grooves 2 to further enhance the meshing of the synchronous belt teeth ends. The stability of the engagement is improved by the structure of the bottom auxiliary groove 6, which allows it to engage with the teeth of the synchronous belt, increasing the contact area and meshing tightness, effectively improving the anti-slip ability. In addition, a small amount of lubricant can be stored in the bottom auxiliary groove 6, which reduces wear and forms a small negative pressure on the surface, enhancing the adsorption force and further improving the anti-slip effect. The structure of the upper transition tooth surface 7, which is located between two adjacent pulley tooth grooves 2, is connected to the corresponding side tooth surfaces 3 on both sides, increasing the contact area and meshing tightness, effectively improving the anti-slip ability.

[0033] By using the structure of the auxiliary anti-slip mechanism, side retaining rings 8 are fixedly installed on both sides of the wheel body 1 of the synchronous belt pulley, and two limiting half rings 10 are installed inside the side retaining rings 8. This can effectively limit the axial displacement of the synchronous belt and avoid poor meshing and slippage caused by lateral offset. At the same time, the pad layer 11 can reduce impact and noise, and multiple pad grooves 12 are evenly opened on the pad layer 11 to improve the impact resistance of the pad layer 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
