[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] See also Figures 1 to 3, the utility model provides an embodiment: a gear with heat dissipation effect, including a gear body 1, a plurality of gear teeth 2 arranged in a circumferential array are provided on the gear body 1, the gear teeth 2 are mainly used for engaging with other gears, each gear tooth 2 is provided with a first flow groove 3, the first flow groove 3 is adapted to the circumferential direction of the gear body 1, and a meshing groove 4 is provided between any two adjacent gear teeth 2, a second flow groove 5 is provided in the meshing groove 4, a first flow groove and a second flow groove, and the first flow groove 3 and the second flow groove 5 form two flow channels in different directions. Through the two flow channels, the contact area between the gear tooth 2 and the airflow is increased, and heat exchange is performed with the airflow to achieve heat dissipation effect and improve the service life of the gear.

[0019] In this embodiment, the gear body 2 is further provided with a plurality of inserting slots 6 , into which flow guides 7 are inserted, and the plurality of flow guides 7 are evenly arranged along the axial direction of the gear body 1 .

[0020] In this embodiment, an air guide groove 8 is provided on the air guide member 7. The end of the air guide member 7 close to the gear body 1 is a flat surface, and the flat surface is in conflict with the gear body 1. The plugged-in air guide member 7 can rotate synchronously with the gear body 2. The air guide groove 8 increases the contact area with the airflow, and heat exchange is performed with the airflow, thereby further improving the heat dissipation effect.

[0021] The opening at the starting end of the air guide slot 8 is larger than the opening at the tail end of the air guide slot 8, and the air guide slot 8 gradually becomes smaller from the starting end to the tail end. Through this structure, the airflow can be compressed and the air pressure of the airflow discharged from the tail end of the air guide slot 8 can be increased. The tail end of one air guide slot 8 is aligned with the starting end of the corresponding and adjacent other air guide slot 8, and the airflow with increased air pressure enters the next air guide slot 8. The airflow simultaneously drives the air from the surrounding side to enter, further compressing the air, increasing the air pressure flow rate, and further improving the heat exchange efficiency between the inner wall of the air guide slot 8 and the airflow, thereby improving the heat dissipation effect.

[0022] The meshing groove 4 is adapted to the shape of the gear tooth portion 2 , and the gear tooth portion 2 of another gear can be inserted into the meshing groove 4 to achieve a gear meshing effect; and the second flow groove 5 and the axis of the gear body 1 are parallel to each other.

[0023] The openings at both ends of the first flow groove 3 gradually expand from the middle of the first flow groove 3 to the outside. When the gear body 1 rotates, the above-mentioned opening structure can increase the airflow entering the first flow groove 3, further improve the heat dissipation effect, and increase the service life of the gear.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
