[0014] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0015] A self-heat dissipating gear comprises: a gear assembly 1 and an end cover assembly 2, wherein both ends of the gear assembly 1 are fastened to the end cover assembly 2 by bolts.

[0016] The gear assembly 1 includes: a gear body 1-1, an air guide groove 1-2, a heat dissipation fin 1-3 and a trapezoidal notch 1-4. A plurality of the air guide grooves 1-2 are evenly arranged on the end surfaces of both sides of the gear body 1-1, a plurality of the heat dissipation fins 1-3 are evenly arranged on the end surfaces of both sides of the gear body 1-1, and a plurality of the trapezoidal notches 1-4 are vertically arranged on each of the heat dissipation fins 1-3.

[0017] The two end cover assemblies 2 each include: an end cover 2-1, an arc-shaped plate 2-2 and an air inlet 2-3. A plurality of the arc-shaped plates 2-2 are evenly distributed on one end surface of the end cover 2-1. A plurality of the air inlet holes 2-3 are penetrated through the end cover 2-1. The plurality of the air inlet holes 2-3 are alternately arranged with the plurality of the air inlet holes 2-3.

[0018] The working principle of this utility model is:

[0019] The heat generated by the gear body 1-1 when it rotates is transferred to the heat dissipation fins 1-3. The rotation of the gear body 1-1 drives the heat dissipation fins 1-3 to rotate. The heat dissipation fins 1-3 can dissipate heat by hitting the wind. At the same time, the trapezoidal notches 1-4 set on the heat dissipation fins 1-3 allow air to flow from the wide end of the trapezoidal notches 1-4 to the narrow end, thereby increasing the flow rate of air passing through the trapezoidal notches 1-4. The increased air flow rate shortens the heat dissipation time, allowing the gear body 1-1 to dissipate heat quickly. The rotation of the gear body 1-1 drives the end cover assembly 2 to rotate, and the rotation of the end cover assembly 2 drives the arc plate 2-2 to rotate. The arc plate 2-2 rotates to inhale air through the air inlet 2-3 and blow it onto the end face of the gear body 1-1, which can dissipate heat for the gear body 1-1. At the same time, when the wind enters the air guide groove 1-2, it moves along the air guide groove 1-2 toward the teeth and blows onto the teeth of the gear body 1-1, which can dissipate heat for the teeth.

[0020] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
