摘要：

Based　on　the　magnetic　flux　leakage　detection　principle　of　magnetic　dipole,　a　model　of　magnetic　flux　leakage　signal　of　gear＇s　early　local　micro　crack　is　derived.　The　characters　of　the　crack　area　that　include　the　peak　in　the　tangential　component　of　magnetic　flux　leakage　signal,　pass　zero　point　in　normal　component　and　the　peak　in　the　gradient　of　it　are　analyzed.　The　analysis　results　provide　the　basic　theoretical　foundation　of　the　Metal　Magnetic　Memory　application.　Then　based　on　the　theory　above,　the　detection　of　micro　crack　on　the　side　of　an　actual　gear　is　applied　which　includes　static　testing　and　dynamic　detection　with　load.　The　detection　position　and　load　effect　on　detection　results　is　analyzed.　The　detection　results　show　the　effectiveness　of　the　peak　in　the　gradient　of　normal　component　magnetic　flux　leakage　signal　normal　component　in　the　gear　magnetic　flux　leakage　signal　model　and　the　feasibility　of　the　magnetic　memory　testing　on　gear　fault.　©　2011　IEEE.
