This work is devoted to analysis of a new method for the experimental evaluation of the fatigue resistance of rims of large nitrided gears with internal gears by testing their fragments (sectors) under cyclic lateral bending. The changes in cyclic strength of 38H2MJuA steel rims caused by nitriding and various modes of details heat treatment before nitriding are comparatively evaluated.
