Abstract
The invention concerns hydrostatic bearings supplied with fluid under pressure for a shaft rotating at high speed in a fixed bed, with the goal of reducing the power dissipated by shear of the fluid in the said bearings. According to the invention, a sleeve (5) is disposed coaxially to the shaft (1) in a chamber arranged for this purpose between the bed (3) and the shaft (1), with apertures being arranged respectively in the shaft and in the bed, opposite the sleeve on one side and the other, in such a way that a movement in rotation can be imparted to the sleeve (5), the structure being particularly applicable to fluid pumps.
Claims6
Hydrostatic bearing with fluid under pressure for a shaft rotating at high speed in a fixed bed, unique in that a sleeve is arranged coaxially to the said shaft in a chamber created for this purpose between the said bed and the said shaft, with apertures supplied with fluid being disposed respectively in the said shaft and in the said bed, opposite the said sleeve on one side and the other, in such a way that a movement in rotation around its axis can be imparted to the said sleeve.
