[0004] The purpose of the utility model can be achieved by the following technical solutions: A high-strength gear, comprising a gear body, a keyway, and a plurality of teeth located outside the gear body. It is characterized in that annular fixing parts are arranged on both sides of the gear body, reinforcing ribs for improving the strength of the teeth are arranged on the fixing parts, and supporting parts for supporting the reinforcing ribs are arranged on both sides of the reinforcing ribs;

[0005] A connecting part is arranged between the teeth, a connecting plate for strengthening the strength of the connecting part is arranged on the connecting part, and both sides of the connecting plate are connected to the bottom of the reinforcing rib.

[0006] In the above-mentioned high-strength gear, the reinforcing rib extends from the fixing part to the front end of the tooth. The reinforcing rib has a two-stage structure. The lower end of the reinforcing rib is trapezoidal, and the upper end of the reinforcing rib is triangular.

[0007] In the above-mentioned high-strength gear, the supporting part extends from the middle of the reinforcing rib to both sides of the tooth and reaches the edge of the tooth.

[0008] In the above-mentioned high-strength gear, reinforcing plates for improving the strength of the keyway edge are arranged on both sides of the keyway, a supporting plate for supporting the reinforcing plate is arranged between the reinforcing plate and the fixing part, and the supporting plate, the reinforcing plate, and the fixing part form a triangular structure.

[0009] Compared with the prior art, the high-strength gear realizes the purpose of strengthening the gear through multiple components for fixing and supporting on the gear body, effectively improving the strength of the gear. Brief Description of the Drawings

[0010] Figure 1 is the main body schematic diagram of the high-strength gear;

[0011] Figure 2 is the partial view of the high-strength gear.

[0012] In the figure, 1 is the gear body; 2 is the keyway; 3 are the teeth; 4 is the fixing part; 5 are the reinforcing ribs; 6 is the supporting part; 7 is the connecting part; 8 is the connecting plate; 9 is the reinforcing plate; 10 is the supporting plate. Detailed implementation mode

[0013] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0014] As Figure 1 、 Figure 2 shown, this high-strength gear includes a gear body 1, a keyway 2, and a plurality of teeth 3 located outside the gear body 1. Circular fixing parts 4 are provided on both sides of the gear body 1. Reinforcing ribs 5 for improving the strength of the teeth 3 are provided on the fixing parts 4. Supporting parts 6 for supporting the reinforcing ribs 5 are provided on both sides of the reinforcing ribs 5;

[0015] A connecting part 7 is provided between the teeth 3. A connecting plate 8 for strengthening the strength of the connecting part 7 is provided on the connecting part 7. Both sides of the connecting plate 8 are connected to the bottom of the reinforcing ribs 5. The supporting part 6 can support the sides of the teeth 3 to increase their strength. The connecting plate 8 is used to increase the connection between the teeth 3 to prevent the connection between the teeth 3 from cracking during the use of the gear body 1.

[0016] The reinforcing ribs 5 extend from the fixing parts 4 to the front end of the teeth 3. The reinforcing ribs 5 are of a two-piece structure. The lower part of the reinforcing ribs 5 is trapezoidal, and the upper part of the reinforcing ribs 5 is triangular. The supporting parts 6 extend from the middle of the reinforcing ribs 5 to both sides of the teeth 3 to the edges of the teeth 3. The two-piece reinforcing ribs 5 enable the gear body 1 to transfer the force received during rotation to both sides to the reinforcing ribs 5 during rotation, and accumulate the force-bearing points in the middle of the two sections of the reinforcing ribs 5.

[0017] Reinforcing plates 9 for improving the edge strength of the keyway 2 are provided on both sides of the keyway 2. A supporting plate 10 for supporting the reinforcing plates 9 is provided between the reinforcing plates 9 and the fixing parts 4. The supporting plate 10, the reinforcing plates 9, and the fixing parts 4 form a triangular structure. This structure can give greater supporting force to both sides of the keyway 2 after fitting to prevent the keyway 2 from cracking and breaking due to centrifugal force or external force during the rotation of the gear body 1.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0019] Although terms such as gear body 1, keyway 2, tooth 3, fixing part 4, reinforcing rib 5, supporting part 6, connecting part 7, connecting plate 8, reinforcing plate 9, and supporting plate 10 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
