Design and Performance Analysis of Hydrostatic Sliding Bearing for High Speed and Precision Electric Spindle
At present,in order to fully meet the performance requirements of high-speed precision motorized spindle hydrostatic plain bearings,the design scheme is analyzed in detail on the basis of understanding the design requirements of hydrostatic plain bearings of motorized spindle.The performance grid division and parameter adjustment scheme of electrospindle hydrostatic plain bearing are studied by ANSYS modeling and analysis method,and the harmonic response of the improved electrospindle is evaluated.According to the field test results of electrospindle hydrostatic plain bearings,the bearing design introduced in this paper is technically feasible,and can ensure the horizontal and vertical stiffness changes of bearings,and is worthy of popularization and application.
