Three-dimensional pressure- and shear-driven flow phenomena in a circular recess of a hydrostatic rotary table

Abstract: The three-dimensional pressure-and shear-driven flow phenomena in a circular recess of hydrostatic rotary table in heavy-duty computer numerical control machines is very complicated and has not been fully explored. Navier-Stokes equations have been applied through the whole flow region using a finite volume approach to explore this complicated flow phenomena, including the influences of feeding Reynolds number (Re i ), sliding Reynolds number (Re s ) and the recess geometry on flow behaviors. A test rig based … Show more

“…Bakker and van Ostayen (2010) determined the minimum dissipation for annular recess thrust bearings operating at a certain rotational speed by finding the optimum film thickness in the recess. Shen et al (2014) studied a threedimensional numerical investigation and some experimental results supporting evidence on the flow structure and the pressure distribution in an annular thrust pad bearing of hydrostatic system in machine tools. The results will be useful for improving the load capability and fluid film stiffness of the thrust pad bearing of hydrostatic systems in machine tools at a low rotating speed.…”
