SLEEVE FOR HYDROSTATIC OR HYDRODYNAMIC BEARING, METHOD FOR MOUNTING SUCH A SLEEVE ON A SHAFT, ASSEMBLY FORMED BY SUCH SLEEVE AND SHAFT Russian patent published in 2018 - IPC F16C17/02 F16C43/02 

FIELD: machine building.

SUBSTANCE: invention relates to a sleeve, provided for mounting on the shaft of a rotating machine to create an internal surface of a hydrostatic or hydrodynamic bearing, and is aimed to the possibility of maintaining the tolerance for machining the outer surface of the sleeve. Sleeve comprises a cylinder and a hoop. Cylinder consists of several parts, coupled with the provision of assembly without deformation of the outer surface of the cylinder. Cylinder has radial threaded through holes, screws installed in the holes and made with contact with the shaft and adjusting the position of the axis of the cylinder relative to the axis of the shaft, and radial threaded blind bores. Outer surface of the hoop forms the inner surface of the bearing. Hoop contains elements, fixed on the cylinder while maintaining the tolerance for machining of said outer hoop surface. Hoop has radial through holes, combined with radial threaded blind bores of the cylinder.

EFFECT: for mounting the sleeve on the shaft, the hoop is designed to be screwed onto the cylinder by means of screws passing the through holes and screwed into the bores.
