摘要：

In　order　to　improve　the　carrying　capacity　and　the　stability,　a　new　structure　of　journal　bearing　with　deep　transition　cavity　is　put　forward.　By　using　differential　method　with　fractionized　grid　considering　the　boundary　condition　of　the　bearing,　the　characteristic　analysis　and　optimization　design　are　carried　out.　Serial　characteristic　data　and　structure　parameters　of　the　bearing　are　obtained.　The　bearing　is　provided　with　the　performance　of　large　load　capacity　and　high　stability.　Comparing　with　general　journal　bearing,　the　load　capacity　of　the　new　bearing　can　be　increased　by　18%-98%,　the　attitude　angle　is　decreased　from　43°　to　14°　and　the　stable　rotate　speed　can　be　increased　by　10%-75%　under　general　work　condition.　The　pressure　distribution　and　eccentricity　ratio　of　the　bearing　is　measured　on　the　HZS-1　bearing　test-bed.　Experiment　results　is　well　coincided　with　theory　results.
