Hydrostatic Guide Rail in Tilt State Oil Pad Bearing Performance Analysis

Abstract

The rectangular pad is widely used in the hydrostatic guide rail, but hydrostatic guide rail in conditions for the emergence of the partial load or deformation factors, makes the hydrostatic guide rail in tilted state of bearing capacity of oil pad has a certain influence. This micro element method to establish hydrostatic guide rail are based on the actual working conditions of Reynolds equation, and then based on the finite difference method to solve the single rectangular pad under uneven oil film thickness of oil film pressure distribution, oil pad oil cavity pressure, as well as the carrying capacity of changing with the guide rail inclination. Through analysis shows that oil cavity pressure and oil pad bearing capacity with larger guide angle, both of them show a trend of slow decline.
