Kinematic　and　the　direction　of　the　power　flow　for　closed　planetary　bevel-type　CVT　are　performed.　The　relationship　between　partition　coefficient　of　power　and　power　flow　in　closed　system　is　studied　by　analyzing　closed　planetary　bevel-type　CVT,　the　expressions　between　power　partition　coefficient　and　the　basic　speed　ratios　are　established,　the　necessary　conditions　with　no　recirculation　of　power　for　closed　planetary　bevel-type　CVT　are　determined.　Sixteen　possible　interconnections　of　parallel　planetary　gear　train　and　planetary　bevel-type　CVT　are　obtained.　A　effective　compact　analysis　processing　method　for　design　of　closed　planetary　bevel-type　CVT　with　no　recirculation　of　power　is　offered.
