【Abstract】 So far,littk has been reported in felevant literature on the performance study,especial-ly the study of static characteristics of gas-lubricated bearings with surface restriction com-pensation.A new hybrid gas-lubricated journal bearing with surface restriction compensation by muItiple sawtooth grooves is proposed.Static and dynamic Reynolds equations are solved by FEM,The effects of the main design parameters of the bearing on bearing performance are studied.According to calculated results,it is shown that sawtooth grooves are capable of producing greater hydrodynamic wedge effect and the groove depth as well as the number of grooves exert significant effects on bearing characteristics,However,the groove depth could be the most decisive design parameter.Compared with existing ones,the bearing proposed by the authors exhibits better performance.更多还原
