Abstract
In order to increase the bending and contact strengths of cylindrical gears, after chemical heat treatment, their teeth, as a rule, are subjected to shot peening and subsequent finishing machining. Studies have shown that mechanical heat grinding of gears with worm grinding wheels made of cubic boron nitride provides higher compressive stresses in the surface layer of the teeth and higher bending and contact strength compared to grinding with abrasive wheels. Keywords: gear grinding, shot peening, tooth strength, internal stress, chemical heat treatment. alexandr_kalashnikov45@rambler.ru, morgunov@mami.ru, chelendger1@mail.ru, ggglilo@mail.ru
