ANALYSIS OF BEARING PERFORMANCE OF HYDRODYNAMIC AND HYDROSTATIC BALL BEARINGS UNDER INTERFACE SLIP BASED ON ORIFICE THROTTLING
Due to study the influence of interfacial slip on the bearing capacity of hydrostatic and hydrostatic ball bearings with small orifice throttling, the Reynolds equation of ball bearings considering interfacial slip was established based on the linear slip model of interfacial slip. The Reynolds equa...

| description | Due to study the influence of interfacial slip on the bearing capacity of hydrostatic and hydrostatic ball bearings with small orifice throttling, the Reynolds equation of ball bearings considering interfacial slip was established based on the linear slip model of interfacial slip. The Reynolds equation and the oil film thickness equation are solved by the finite difference method and the relaxation iterative method. The oil film pressure distribution and bearing capacity of the hydrostatic ball bearing considering interface slip are calculated. The results study that the higher the oil supply pressure, the higher the rotational speed, the smaller the oil film clearance, the stronger the dynamic pressure effect and the greater the bearing capacity of the hydrostatic bearing. Considering the sliding effect, the interface sliding leads to the increase of oil film pressure, and the influence on bearing capacity has a critical value. When the oil film gap is larger, the critical value of slip coefficient is larger, the liquid slip effect is stronger, and the carrying capacity increases when the slip degree is lower than the critical value, but decreases when the slip degree is higher than the critical value. |
