hydrostatic bearing

hydrostatic bearing

[‚hī·drə′stad·ik ′ber·iŋ]
(mechanical engineering)
A sleeve bearing in which high-pressure oil is pumped into the area between the shaft and the bearing so that the shaft is raised and supported by an oil film.

For a hydrostatic bearing having the diameter D = 50 mm, the shaft's length L = 100 mm, the mass M = 3 kg and running between Nmin = 1 rpm and Nmax = 2500 rpm we tried a lot of numerical integration using Runge-Kutta integrator of IVth order from MATLAB utility, alternating all the parameters of the system in the normal running limits of the bearing but even in the outer of these.
