The utility model discloses a double-arc gear. The gear comprises gear teeth which are sequentially distributed on the gear, the basic tooth profile of each gear tooth comprises a convex arc at the tooth top and a concave arc at the tooth root; the convex arc is connected with the concave arc through a straight line section, the straight line section intersects with the convex arc and the concavearc, and the distance H1 from the intersection point of the straight line section and the convex arc to the gear pitch circle D is smaller than the distance H2 from the intersection point of the straight line section and the concave arc to the gear pitch circle D; through the design that the tooth profile generated and machined by the straight line section serves as the involute, due to the fact that the involute participates in meshing, the bearing capacity, the transmission efficiency, the transmission stability and the service life of the gear are improved, and in addition, pitting corrosion of the involute tooth p
