The invention discloses a high-strength bevel gear. The high-strength bevel gear comprises a bevel gear body and a non-bevel gear body; the high-strength bevel gear is in a LogiX tooth shape, the part(tooth top) above a pitch line (the bevel gear is degraded into a pitch circle) is convex, the part (tooth root) below the pitch line is concave, and in the transmission process, a pair of gear teethcan achieve convex-concave meshing; the tooth profile is formed by connecting a series of feature points, the curvature centers of the feature points are on a pitch curve (pitch circle), and when thepair of tooth profiles are meshed at the corresponding feature points, the curvature centers coincide and fall at nodes, so that the instantaneous pure rolling condition is met; and compared with aninvolute tooth profile, the tooth surface contact stress and the slip rate are greatly reduced, the friction is reduced, the tooth root thickness is increased to a certain extent, the number of teethcan be designed to be smaller
