Abstract：

The　relationship　between　the　cage　slip　ratio　and　characteristic　frequencies　was　obtained　by　theoretical　deduction.　The　correctness　of　the　derivation　formulas　was　verified　by　the　rotor　experiment　bench　supported　by　cylindrical　roller　bearings.　And　the　variation　law　of　the　slip　ratio　of　the　cage,　the　actual　characteristic　frequencies　and　the　theoretical　values　deviations　with　the　rotational　speed　were　studied.　Results　showed　that　the　slip　ratio　and　the　deviation　tended　to　increase　with　the　growth　of　the　shaft　rotating　speed.　The　research　conclusion　has　the　guiding　significance　for　the　fault　diagnosis　of　the　aeroengine　main-bearings.　©　2019,　Editorial　Department　of　Journal　of　Aerospace　Power.　All　right　reserved.
