To　conduct　research　on　the　profile　modification　of　inner　gear　of　cam　profile　rolling　movable　teeth　transmission,　4　parameters　modification　modes　based　on　inner　gear　profile　equation　and　numerical　control　manufactures　are　proposed　and　the　universal　equation　for　inner　gear　profile　modification　is　established.　According　to　the　current　of　inner　gear　parameters　changing　and　forcing　trait,　two　compounded　profile　modification　ways,　Crest-Root　Compound　and　Angle-Crest-Root　Compound　are　suggested.　Then　an　example　for　explaining　the　above　is　demostrated,　which　shows　that　we　can　get　expectant　result　through　compound　modification.
