PRESS FIT JOINTS FOR MOUNTING BY MEANS OF A PRESSURE MEDIUM

摘要

The invention relates to a press fit joint which joint is mounted by means of a pressure medium. The joint comprises an inner and an outer part provided with co-acting tapered press fit surfaces and in which the axial force required for obtaining the joint is obtained from a pressing device. This device comprises an annular piston which is fixed to one part of the joint and is axially displaceable in relation to the other part of the joint and which together with portions of the respective joint parts limits a cavity which is connected to the press fit surfaces and to which a pressure medium can be supplied. The pressure medium is inserted between the press fit surfaces in the joint through a channel which ends directly at or in a groove in one of the press fit surfaces of the joint in a position between the end portions of the surface and from there is brought into the pressing device via those parts of the press fit surfaces which are situated between the channel end and the pressing device.
