Abstract：Normal modulus was usually as design standard of involutes helical gear , there were advantages but if involute helical gear take face modulus as standard .Based on the characteristics of two standard gears , this paper analyzed and compared their geometry parameters , processing and mapping methods .It showed a design advantage was thin or no undercut when face modulus was as standard processing herringbone gear .It provided a reference for selection and application of helical gear and herringbone gears processing methods .
