sine-similar profile of teeth

DESIGN OF FORMING BY HELIX COAXIAL FORMATIVE LINES OF TOOTH FLANK OF SPUR HELICAL GEAR

Aim. Development of mathematical model for process of teeth profiling of spur helical gear by disk cutting tool by the radial and round kinematic modify formation method on the basis conception of forming of teeth flanks by spatial helix coaxial formative lines. Method. Researches are based on methods and substantive provisions of the theory of parts surfaces formation by cutting instruments, in particular formation of spur gear teeth, the tooth system theory, kinematics analysis, analytical and differential geometry.
