Gleason's Cage bevel and hypoid gear design and manufacture software is available with a seamless link to Smart Manufacturing Technology's Masta full-system transmission design and analysis software. The design-to-manufacture integration was developed to improve workflow, taking into account design geometry of gears via machine settings within the context of the full system. The combined software enables full-system durability and NVH analyses at any stage of production to solve bevel and hypoid noise problems. In addition, the user can optimize gear-flank geometry by performing system-level loaded tooth contact analysis. The improved virtual analysis and testing capability is intended to avoid the costs associated with repeated manufacturing and testing of prototype gears.
