| Abstract: | Flexural strength is a principal factor that defines the fatigue life of face gear.A new tooth structure with circular arc of fillet part for the face gear tooth are developed and a shaper with tooth rounded top is applied to generate the fillet part of helical face gear.The thesis derived the equations of fillet surface of the shaper.The coordinate systems are created for the face gear machining,with which the equations of fillet surface of face gear is conducted from the equations of rounded top of the he... |
