Abstract：

Lubrication　performance　of　three　axial-grooved　gas-lubricated　hydrodynamic　journal　bearing　with　micro　grooves　was　investigated.　Parabolic　micro　grooves　were　textured　on　the　surfaces　of　the　pads　of　three　axial-grooved　gas-lubricated　hydrodynamic　journal　bearing　and　a　mathematical　model　of　the　dimensionless　gas　film　thickness　of　the　gas-lubricated　bearing　was　established.　The　dimensionless　steady　Reynolds　equation　was　solved　by　the　finite　element　method,　and　then　the　nonlinear　gas　film　pressure　distribution　was　obtained.　The　numerical　results　showed　that　the　finite　element　method　for　solving　the　steady　Reynolds　equation　of　three　axial-grooved　gas-lubricated　hydrodynamic　journal　bearing　is　effective,　and　the　dimensionless　load-carrying　capacity　can　be　increased　and　the　friction　coefficient　can　be　reduced　when　micro　grooves　are　textured　on　the　surfaces　of　the　pads　of　the　gas-lubricated　bearing.　©　2015　Taylor　&　Francis　Group,　London.
