Research on the Characteristics of the Hydrostatic Support Turntable of Large Gear Grinding Machine Based on AMESim
In order to improve the machining accuracy of large CNC gear grinding machines,the overall structure and working con-dition of the hydrostatic bearing turntable of gear grinding machine were studied,and the theoretical model for solving the oil film thick-ness and output flow rate was analyzed.The results show that the eccentric loading has a great influence on the oil film thickness.In or-der to further verify,on the basis of analyzing the existing parameters design methods,the system model was established by AMESim software,and the system dynamic simulation analysis was carried out for different working conditions and structural parameters.The sim-ulation results show that the structural parameters of the hydrostatic bearing turntable can ensure that the turntable can produce suffi-cient bearing capacity.The influence of flow pulsation on the change rate of oil film thickness is less than 0.4％,and the influence of ec-centric loading on the change rate of oil film thickness is up to 13％.The static and dynamic simulation results are consistent with the actual data,and the performance test results meet the design requirements of the grinder.
