Rolling　bearing　is　a　key　supporting　component　for　major　equipment　such　as　precision　machine　tools　and　special　vehicles.　Lubrication　performance　directly　determines　the　stable　serving　performance　of　the　bearing,　which　in　turn　affects　the　performance　indicators　of　major　equipment.　In　this　paper,　the　operating　characteristics　were　studied　based　on　the　theoretical　simulation　and　experimental　analysis　for　the　oil-air　lubrication　rolling　bearings　under　the　wide-range　lubrication　parameters.　Firstly,　according　to　the　multi-phase　flow　analysis　technology,　the　flow　state　of　oil　and　gas　in　the　high-speed　angular　contact　ball　bearing　was　studied,　and　a　basic　law　of　oil　and　gas　flow　inside　the　bearing　was　revealed.　Then,　an　experiment　platform　was　designed　to　validate　the　rolling　bearing　lubrication　performance.　The　influence　of　different　lubrication　parameters　on　the　bearing　temperature　was　experimentally　analyzed,　the　optimal　bearing　lubrication　parameters　with　the　smallest　temperature　rise　at　a　specific　rotation　speed　were　obtained,　and　the　influence　of　the　different　lubrication　parameters　on　its　service　performance　was　confirmed.　The　research　results　provide　a　basis　for　the　service　performance　analysis　of　rolling　bearings　under　wide-range　lubrication　conditions.　©　2018,　Materials　Review　Magazine.　All　right　reserved.
