[0024] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0025] Combined with Figure 1-4As shown, a sprocket wheel that is easy to replace tooth shape includes a sprocket body 1 and outer gear teeth 2. The outer edge of the sprocket body 1 is circumferentially distributed with a plurality of gear tooth bodies 9, and gear tooth grooves 10 are opened between adjacent gear tooth bodies 9. An insert plate 6 is arranged in the middle of the bottom of the outer gear teeth 2, and the insert plate 6 is inserted into the gear tooth groove 10. The sprocket body 1 is circumferentially provided with a plurality of fixing blocks 12, and the outer gear teeth 2 are circumferentially provided with a plurality of fixing blocks 2 11.

[0026] Specifically, a groove 13 is provided between the fixing block 12 and the fixing block 2 11, and the bottom height of the groove 13 of the fixing block 12 is flush with the bottom height of the groove 13 of the fixing block 2 11, so that when external connecting parts such as tension springs are installed, the connection between the outer gear 2 and the sprocket body 1 can be ensured to be horizontal, which helps to stabilize the connection.

[0027] Specifically, clamping plates 7 are symmetrically arranged on both sides of the bottom of the outer gear 2, and a magnetic layer 8 is arranged on the side of the clamping plate 7 close to the plug plate 6. The clamping plate 7 is magnetically connected to the upper and lower surfaces of the gear body 9 through the magnetic layer 8. The magnetic connection between the clamping plate 7 and the gear body 9 further improves the tightness and firmness of the installation of the outer gear 2.

[0028] Specifically, a plurality of square holes 3 are circumferentially arranged on the sprocket body 1 , and reinforcing ribs 4 are arranged in the square holes 3 . The arrangement of the square holes 3 is conducive to heat dissipation and reducing the weight of the sprocket body 1 , while the arrangement of the reinforcing ribs 4 further improves the overall structural strength of the sprocket body 1 .

[0029] Specifically, a tension spring or a high-strength alloy steel wire rope is connected between the fixed block 12 and the fixed block 2 11, and is installed and connected in the groove 13 through the tension spring or the high-strength alloy steel wire rope, so that the outer gear 2 is installed more tightly and firmly on the gear tooth body 9 in the radial direction, ensuring the stability of the sprocket meshing during operation.

[0030] Specifically, a wear-resistant pad 14 is arranged in the middle of the top of the outer gear tooth 2, and a slot 15 corresponding to the wear-resistant pad 14 is arranged in the middle of the top of the outer gear tooth 2. The wear-resistant pad 14 is snapped into the slot 15. The arrangement of the wear-resistant pad 14 is beneficial to enhancing the wear resistance of the outer gear tooth 2, ensuring smooth meshing of the chain and the sprocket, and further improving the service life of the outer gear tooth 2.

[0031] Specifically, a mounting hole 5 is provided in the middle of the sprocket body 1 , and the mounting hole 5 is used for mounting the sprocket body 1 .

[0032] In addition, if the tooth shape of the sprocket needs to be changed, there is no need to replace the entire sprocket, just replace the outer gear teeth 2, ensure the setting of the plug plate 6 at the bottom of the outer gear teeth 2 and the clamping plates 7 on both sides, and set the shape and parameters of the top of the outer gear teeth 2 as needed.

[0033] The specific working principle of the utility model is as follows:

[0034] By setting a plurality of plug-in plates 6 of the outer gear 2, the plug-in plates 6 are plugged into the gear groove 10, and the magnetic connection between the clamping plate 7 and the gear body 9 is matched, so that the installation and removal of the outer gear 2 are facilitated, so that the installation and removal time of the outer gear 2 is greatly reduced, and the outer gear 2 is installed and connected in the groove 13 of the fixing block 12 and the fixing block 2 11 through the tension spring or high-strength alloy steel wire rope, so that the outer gear 2 is more tightly and firmly installed on the gear body 9 in the radial direction, ensuring the stable installation of the outer gear 2. When the outer gear 2 needs to be replaced, the plug-in plate 6 of the outer gear 2 can be directly pulled out of the gear groove 10 by untying the tension spring or high-strength alloy steel wire rope.

[0035] The above is only a preferred implementation of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention should be included in the protection scope of the present invention.
