A　new　design　of　rapid　inspection　machine　for　automotive　gears　based　on　Gear　Integrated　Error　(GIE)　technology　is　introduced　in　this　paper　The　novel　equipment　can　be　used　in　production　workshops　to　get　analytical　results　such　as　profile　deviations　and　pitch　deviations　of　spur　and　helical　cylindrical　gears.　The　distinguishing　features　of　GIE　are　summarized　by　analyzing　the　principle　of　GIE　method,　the　specific　measuring　master,　and　the　curves　of　GIE　measuring　results.　Then　the　design　approach,　system　structure,　procedure　of　inspection,　key　parameters,　and　specifications　of　the　newly　designed　rapid　inspection　machine　are　introduced.　It　is　difficult　and　critical　in　the　GIE　technology　to　distinguish　the　involute　meshing　phase　and　to　determine　the　exact　coordinates　of　the　starting　and　end　points　in　a　GIE　curve.　An　innovative　algorithm　is　also　proposed　to　solve　this　problem.　The　performance　of　the　rapid　inspection　machine　has　been　verified　by　experiments　in　two　aspects,　the　accuracy　and　the　efficiency.　It　can　be　seen　that　the　accuracy　of　the　rapid　inspection　machine　for　automotive　gears　is　good　enough　to　meet　the　design　requirements　and　the　efficiency　is　much　higher　than　Gear　Measuring　Centers　(GMCs).
