The paper proposes a method of cutting by generating spur gears using rack cutter with modified geometry. analytical equations the tooth profile rack-gear are deduced, both for involute zone and filleting region, based on remark that is envelope successive positions tool. undercutting radius obtained from system transcendental which requires numerical solving it. Compared to standard profile, d...

Stress state of the surface layer in contact zone mating teeth cylindrical gears has been studied. It is established that stressed surfaces meshing pole characterized not only by stresses, but also deep equivalent stresses. shown under loading heterogeneous and changes with distance from surface. Analysis substantiation calculation model for diffusion surface-hardened are performed. Value coeff...
