Method for fitting the roll mantle of a tubular roll intended for a paper machine or equivalent with glide bearings and a tubular roll that makes use of the method.

摘要

The invention concerns a method for fitting a tubular roll mantle of a roll intended for a paper machine or equivalent with glide bearings. In the method the roll mantle (12) is supported on a stationary roll axle (11) by means of hydraulic glide bearing elements (14,14a,15,16,16a) acting upon the roll mantle (12) or upon the roll ends (13,13a), said bearing elements being loaded hydraulically by means of the pressure of a pressure medium. In the invention, the roll mantle (12) is supported on the roll axle (11) by means of glide bearing elements (15,16,16a) acting radially and/or axially in opposite directions, so that, when a outside force that shifts or attempts to shift the roll mantle (12) in the direction transverse to the radial principal loading direction and in the axial direction is applied to the roll mantle (12), the pressure in the glide bearing element (15;16,16a) placed at the side of the higher loading is adjusted to a level higher than the pressure in the glide bearing element acting in the opposite direction so that the outside forces are neutralized. In the principal loading direction, the roll mantle (12) is allowed to be shifted over a certain distance, in which case, when the roll mantle (12) approaches its preset extreme position in this direction, the movement of the roll mantle (12) is braked down, and finally the movement is stopped in its extreme position by means of the glide bearing elements (14,14a). The invention also concerns a roll that makes use of the method. <IMAGE>
