摘要：

The　effect　of　center　distance　error　of　machine　tool　employed　in　machining　globoidal　cam　was　discussed.　Based　on　the　offset　surface　theory,　the　equation　of　the　globoidal　cam　profile　and　the　mathematical　model　of　the　profile　error　were　established,　and　the　sensitivity　coefficient　of　the　center　error　was　derived.　The　variation　of　the　sensitivity　coefficient　corresponded　to　different　tool　paths　was　further　investigated.　The　real　profile　and　profile　error　were　simulated　through　VC++　and　PROE　software,　and　the　impact　and　collision　of　the　globoidal　cam　mechanism　caused　by　the　center　distance　error　and　its　generation　mechanism　were　revealed.　Results　show　that　the　center　error　degrades　meshing　quality　and　has　a　bad　influence　on　the　transmission　performances.
