Active aerostatic lubrication technology is an important developing direction of motion bearings of precision/ultraprecision manufacturing equipment,and active aerostatic lubrication has become the hot focus of the academic community recently,which is expected to enhance the dynamic characteristics of aerostatic lubrication bearing such as high loading capacity,high dynamic stiffness and high antidisturbance ability.The research status of active aerostatic lubrication bearings with vacuum preloading,electromagnetic preloading and piezoelectric active compensation was reviewed,the present academic research status of aerostatic lubrication bearings,as well as existing problems,were analyzed.A new development direction of active aerostatic lubrication was suggested,which is combined with active inherent restrictor,active controlled restrictor or gas film shape control.
