Abstract :
In this study, a water-lubricated hybrid bearing with circumferential grooves and stepped recesses is devised for supporting a high-speed spindle system. Due to the low viscosity of water and high rotating speed, this hybrid bearing usually works in a turbulent regime. A computational procedure has been developed to calculate the bearing performance operating under different rotating speeds and supply pressures. The numerical model has taken turbulence and thermal effects into account. The results presented in this study is expected to be useful for the design of hybrid bearings. It will also be helpful to promote the future better test and safe operation of the high-speed spindle system for different machining processes.
