Studying the domains of existence of wave gears with external and internal wave generators

The results of studies of the geometry of involute wave gears with external and internal wave generators are presented. The domains of their existence are obtained and the design parameters are chosen. Unlike the domains of existence for conventional internal and external gear trains, the design domains for wave gears are constructed in the coordinates (x_г; z_г), (w₀/m; z_г), and (w₀/r_с.г; x_г). The flexible and rigid wheel teeth have involute profiles. The resulting domains of existence are calculated using special computational techniques. The proposed approach will allow the designers to choose the engagement parameters of wave gears that are little studied and develop wave gears with desired characteristics.
