According　to　the　simulation　of　the　face　gear　in　UG,　the　research　established　the　model　of　face　gear.　A　perfect　model　that　can　be　used　in　ANSYS　was　obtained　through　reserve　modeling.　The　blending　situation　of　three　models　of　face　gear　was　analyzed　in　ANSYS.　The　blending　stresses　distribution　area　and　the　influence　on　gear　teeth　bending　stresses　of　different　parameters　i.e.　modulus,　width　and　number　of　teeth　were　discussed.　And　the　discipline　of　the　bending　stresses　under　these　parameters　was　got.　It　provides　a　new　analysis　method　to　research　the　characteristics　of　stress　of　face　gear.
