摘要

The gear has a hollow wheel, a thin-walled wave-shaped deformable flexible wheel and a wave generator that produces a deformation wave, which rotates with a drive speed of a transmission. The flexible wheel contacts with the hollow wheel in two diametric regions. A gearing is designed as a helical gearing at the hollow wheel and the flexible wheel. The hollow wheel is axially designed in two parts. A helix angle of the helical gearing is maintained at a preset overlap ratio with selected tooth width, which is designed in double helical gears.
