This invention relates to the machining of gears subjected to mechanical hardening. There is a known method of machining gear wheels using a disk tool, in which the workpiece is penetrated into internal contact with the working elements of the tool, it passes through a continuous planetary gearbox, the H1OFUG axis, the parapeptochemical tool axis of the tool, and ciscrete rotations on the hijacking; equal and and multiple to the angular pitch, the cutting is performed by vapain and the hardening of the teeth by their surface plastic cementation, 1.1. The disadvantage of the aanal method is that the gears processed with its use are not knobby, since the method allows to obtain tooth surfaces with hardening that is close to uniform along the tooth line. At the same time, for barrel-shaped wheels, the most wearable one is the chain of the rim, where the contact spot is localized and the greatest contact voltage occurs. As a result, the teeth wear unevenly and the transmission loses relatively smoothly. The purpose of the invention is to increase the durability of gears by non-dimensional deformation of the sides of the tooth. The goal is achieved by the method of processing gear wheels, which includes heating the tooth with its hardening disk tool, the volume at which the wheel is sequentially inserted into the internal touch with the tool working elements and informs it of a continuous planetary motion around an axis parallel to the geometric axis of the tool, and Accurate turns at an angle, 1 phase angle step, hardening produced by the tool, the radius of curvature of which is greater than that of the tool, which made the cutting teeth / Pr This tool curvature but- polzuemogo for cutting teeth, n are in a ratio of stroke s..i ,, where p is the curvature radius of the tools, which 1roizvod t hardening teeth} R | - the radii of curvature of the tool used to cut the teeth; h is the greatest depth of plastically depleted filament cpo metal; d - the nominal value of the barrel shape of the teeth. FIG. Figure 1 shows the processing scheme (cutting - by a dotted line, strengthening & solid lines); in fig. 2 - view of the end of the tooth. The cutting of the tooth of the wheel 1 is carried out with the disk tool 2, the hardening of the wheel 1 is produced by $ 1t with the disk tool 3. The wheel 1 is sequentially introduced into the internal touch with the working elements of the tool 3 and communicates continuous planetary motion around the axis O parallel to the geometric axis of the tool 3, and discrete turns at an angle that is a multiple of the angular step. The side A of the tooth 4 is deformed non-uniformly due to the fact that the radius of curvature of the strengthening tool 3 is larger.
