[0008] After the above structure is adopted, the utility model has the beneficial effects that:

[0009] The utility model sets up the upper stress groove and lower stress groove to disperse the stress of the gear, and sets up the ball screw to support and strengthen the upper stress groove and lower stress groove, thereby improving the gear strength and ensuring the service life and reliability of the gear body; the connecting strength between the gears can be improved through the reinforcing component, thereby further improving the overall strength. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 The utility model is a structural schematic view.

[0011] Mark explanation:

[0012] 1 gear body, 2 small end face, 3 large end face, 4 bevel, 5 gear tooth, 6 upper stress groove, 7 lower stress groove, 8 spherical bolt, 9 reinforcing assembly, 91 reinforcing rib, 92 plug, 93 bolt, 10 front stress groove, 11 rear stress groove. DETAILED DESCRIPTION

[0013] The utility model will be further explained in connection with the drawings.

[0014] In order to make the utility model purposes, technical scheme and advantages more clearly, the following will be further detailed in connection with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model.

[0015] Reference Figure 1 A high-strength bevel gear, comprising a gear body 1, the gear body 1 includes small end face 2, large end face 3 and bevel 4, bevel 4 is provided with gear tooth 5, the upper stress groove 6 and the lower stress groove 7 of arc structure are arranged at the upper and lower connecting transition of bevel 4 and gear tooth 5, spherical bolt 8 is arranged at the upper stress groove 6 and the lower stress groove 7, and the spherical nut of spherical bolt 8 is abutted on the upper stress groove and the lower stress groove;Reinforcing assembly 9 is arranged in the spacing between gear tooth 5. Specifically, the upper stress groove 6 and the lower stress groove 7 disperse the stress of gear 5, improve the strength of gear tooth 5, spherical bolt 8 is arranged to support and strengthen the upper stress groove 6 and the lower stress groove 7, thereby improving the gear strength, ensuring the service life and reliability of the gear;The connecting strength between gear teeth can be improved by reinforcing assembly 9, thereby further improving the overall strength.

[0016] In the embodiment, reinforcing assembly 9 is arc-shaped reinforcing rib 91, the left and right side walls of reinforcing rib 91 are attached to the corresponding side walls of gear tooth, the bottom of reinforcing rib 91 is flat structure and is attached to bevel 4, plug 92 is arranged at the bottom of reinforcing rib 91, and the plug groove is arranged on the bevel, the plug groove and the plug clearance fit, and bolt 93 is arranged on the reinforcing rib and is fixedly connected with the bevel. The left and right sides of reinforcing rib 91 are attached to the side walls of gear tooth 5, the connecting strength between gear teeth 5 is improved, gear tooth 5 is effectively supported, and the overall strength is further improved;The threaded hole for mounting bolt 93 is preferably counterbore, and the bolt is hexagonal bolt, so as to avoid the protrusion of bolt 93, affect the normal meshing of the gear, and the height of reinforcing rib 91 is also not too high.

[0017] In the embodiment, small end face 2 is provided with front stress groove 10. Front stress groove 10 disperses the stress received by small end face 2, to avoid breakage.

[0018] In the embodiment, large end face 3 is provided with rear stress groove 11. Rear stress groove 11 disperses the stress received by large end face 3, to avoid breakage.

[0019] The above merely aims to explain the technical solutions of the present application but not to limit the present application. Other modifications or equivalent replacements to the technical solutions of the present application made by those skilled in the art should be covered in the scope of claims of the present application as long as they are not beyond the spirit and range of the present application.
