To　measure　and　evaluate　the　pitch　deviations　of　automotive　gears　rapidly　is　a　key　problem.　Two　measures　are　used　to　solve　this　question.　Firstly,　a　specific　rapid　inspection　machine　for　automotive　gears　based　on　the　Gear　Integrated　Error　(GIE)　technology　is　developed.　The　efficiency　of　the　rapid　inspection　machine　is　fairly　high.　The　rotational　speed　of　the　master　worm　is　up　to　200　rpm.　Under　this　condition,　a　profile　of　a　tooth　flank　can　be　measured　in　0.3　second.　The　machine　can　acquire　analytical　results　including　pitch　deviations　rapidly.　Secondly,　a　new　approach　of　gear　evaluation　and　a　set　of　new　parameters　of　the　pitch　deviations　are　proposed　in　this　paper.　The　values　of　the　new　parameters　are　more　stable　than　those　of　the　traditional　parameters　and　are　relatively　not　sensitive　to　random　errors　of　the　measurements.　The　principles　of　the　new　evaluation　system　of　gear　accuracy　based　on　the　statistical　analysis　are　described　and　the　definitions　of　the　new　parameters　of　pitch　deviations　are　proposed.　And　then,　the　rapid　inspection　machine　of　automotive　gears　based　on　the　GIE　technology　is　introduced　as　an　ideal　instrument　that　can　acquire　pitch　deviations　much　more　quickly　than　others.　For　the　verification　of　both　the　effect　of　the　new　parameters　of　pitch　deviations　based　on　statistical　analysis　and　the　efficiency　of　the　rapid　inspection　based　on　GIE,　a　series　of　measuring　experiments　are　performed　under　different　conditions.　A　comparison　of　the　results　shows　that　the　new　parameters　are　suitable　to　evaluate　the　pitch　deviations　of　gears　under　the　condition　of　high　efficiency　measurements.　©　2017　Taylor　&　Francis　Group,　London.
